La idea original de Rudolf Diesel, el inventor alemán del motor de ciclo diesel, era construir un motor que funcionara prácticamente con cualquier combustible. Sin embargo, él nunca pudo imaginar que un motor diesel de hoy llegara a ser un mecanismo tan complejo y delicado, sobre todo, en el combustible que se utilice.
Los primeros motores diesel, de bomba lineal, utilizados en maquinaria agrícola y en algunas camionetas, y camiones en general, funcionaban con un combustible llamado “gasoil”; “gas” significa “combustible” y “oil”, “aceite”. Este combustible siempre se consideró de calidad mediana y muy inferior a la nafta, más refinada. La misma persona que cuidaba mucho sobre qué tipo de nafta le cargaba a su auto y en qué estación de servicio lo hacía, compraba gasoil de donde le resultara más cómodo y económico.
Sin embargo, hoy, la cuestión se ha revertido; cargar nafta de 95 octanos o de 98 octanos, da prácticamente lo mismo porque el motor de inyección lleva un Sensor de Detonación que le indica a la ECU (central electrónica del motor) hasta donde puede exigir al motor de nafta sin romperlo. La ECU se ha construído para que el usuario desinformado no rompa los motores antes de tiempo; después de cierto tiempo, ya no es lo mismo porque las concesionarias no venderían autos nuevos y los mecánicos nos moriríamos de hambre. Los autos tienen que romperse, por una cosa o por otra.
En los motores diesel nuevos (al combustible de mayor Número de Cetanos se le llama “diesel” en lugar de “gasoil”) el combustible utilizado determina la vida del motor. La pregunta lógica es ¿por qué? Si bien el gasoil es un Hidrocarburo (se simplifica con las letras HC) de cadena más larga que la nafta (ambos contienen cadenas carbonadas de Carbono combinado con Hidrógeno), el problema del diesel es que está sometido a presiones y temperaturas más elevadas que la nafta durante la combustión.
Hay un componente de menor porcentual que está presente en el petróleo del que se destila el diesel, y es el Azufre, en cantidades menores que el 1%, por lo que no parecería peligroso en primera instancia. Sin embargo, debido a las elevadas presiones y temperaturas, este Azufre se combina con el Oxígeno del aire y con Hidrógeno del combustible, dando como resultado un porcentaje de ácidos Sulfurosos y Sulfúricos.
Es de común conocimiento que el Ácido Sulfúrico se come lo que sea que toque, salvo algunos materiales, por suerte. Y además tiene cierta debilidad por el Hierro, que constituye en un 95% al acero que se utiliza en los motores. Conclusión, en el diesel hay Azufre que termina atacando al acero de los inyectores y a la misma bomba inyectora.
Hablemos de que la presión en un sistema de inyección moderno llega a los 1.500 Bars en el Common-Rail que alimenta los motores de hoy, y hasta 1.600 Bars en algunos sistemas de Inyector-Bomba utilizados mayormente en motores de camiones. Para tener una referencia, cuando usted infla por completo uno de los neumáticos del auto, utiliza una presión de 30 libras/pulg cuadrada que equivalen SÓLO A 2 BARS. Imagine ahora lo que pueden ser 1.500 Bars de presión. Como referencia le digo que si en funcionamiento se produce una fisura en el sistema, el líquido a alta presión que saldrá cortará como un cuchillo la mano que encuentre cerca.
En resumen, entonces, el ácido producido por el contenido del Azufre, con el tiempo se irá comiendo las toberas de los inyectores electrónicos y los órganos mismos de la bomba inyectora de alta presión, inexorablemente. Estos elementos tienen una superficie cementada (nitrurada) a fin de que no se desgasten, pero el Azufre se encarga de eliminar esa delgada capa, por lo que es fácil imaginar que no hay arreglo para esto, aunque hay talleres que prometen la reparación de los inyectores y de la bomba.
Para tener una idea, los juegos presentes en estos elementos llevan una luz de milésimas de milímetro, al grado que usted no puede intercambiar las agujas de los inyectores sin hacer un desastre, porque cada aguja del inyector tiene su juego permitido en cada cuerpo inyector. Lo que nos dice que será muy difícil recuperar un inyector o una bomba con desgaste, y si se logra, no será por mucho tiempo.
Ahora, si usted debe cambiar un inyector debido al desgaste, deberá cambiar los 4 o los 6 dependiendo del motor, y también hay que irse preparando porque más tarde o más temprano habrá problemas en la bomba (siendo que fallan aún “de fábrica”), todo esto gracias a nuestro amigo el Azufre. Por lo que es muy importante que cuando carga diesel, lo haga en una estación de marca reconocida y que se fije en las especificaciones del combustible que le venden.
Me hace gracia porque hay gente que me dice: “Ah, no, yo cargo sólo en el Automóvil Club” como si eso fuera una garantía de combustible de primera. El ACA utiliza diesel de YPF que tiene 150 partes por millón de Azufre; Esso o Shell utilizan combustible de 10 partes por millón de azufre, pero claro, son marcas extranjeras y el precio es más caro. Bien, usted decida, es su motor y su bolsillo.
Lo que yo le recomiendo, es siempre cargar diesel “grado 3”, que contiene adhitivos para neutralizar el azufre y estabilizar el combustible. ¿Qué significa “estabilizar el combustible”? Que como casi todo en nuestro país, se produce de formas generalmente legales pero no tan generalmente éticas. Por ejemplo, sea nafta o gasoil, para que se entienda, demos un ejemplo: si se necesita una cadena de 10 carbonos, cuando ya no dispongamos de cadenas de 10 carbonos, utilizamos una más pesada, de 20 carbonos, le hacemos “cracking”, perfectamente legal, y obtenemos dos cadenas de 10.
Por supuesto, esto se realiza eléctricamente para “cortar” la cadena de 20 carbonos, pero con el tiempo, estas dos mitades tristemente separadas, se encontrarán y volverán a formar su feliz unión de 20 carbonos, o sea, que con el tiempo uno comienza a ver que el combustible se “pone viejo, o se pudre” y comienza a oler mal, señal de que el Azufre se ha combinado con el Hidrógeno, formando Sulfuro de Hidrógeno, que es el gas que uno libera luego de comerse un exquisito guiso de porotos.
Uno alimenta un motor electrónico de hoy con semejante mezcla y termina tapando los inyectores, al igual que si carga diesel en cualquier estación de cualquier bandera o que no tiene bandera. Y lógicamente, se queda en la mitad de la ruta, cuando menos lo espera. Por eso, cargue diesel Euro, que es más cara pero le dura más kilómetros y no le rompe el motor. ¿Por qué las camionetas que viajan a la cordillera se quedan por el camino a la vuelta? Porque cargaron cualquier cosa en cualquier lado, como si compraran frutillas para el viaje.
Bien, ahora ya sabe lo que pasa cuando utiliza en su motor diesel electrónico, cualquier clase de combustible, a pesar de lo que deseaba Rudolf Diesel, que en paz descanse y que el Cielo lo tenga en su gloria, pero es que la tecnología ha cambiado.

They are extremely useful to bones, muscle tissues, and sexual operate with out the
conversion of androgens into estrogens seen with steroids or prohormones.
SARMs and steroids both provide potential advantages for muscle growth and performance
enhancement, however they differ significantly when it comes to
safety, unwanted effects, and legality. SARMs are sometimes seen as a safer various for beginners or these trying to keep away from harsh
unwanted effects, whereas steroids may be more suitable for
skilled customers looking for speedy results.
LGD 4033 BenefitsWhere Ostarine is probably considered one of the best SARMs
to incorporate in a slicing cycle, LGD has
proven itself as an excellent bulking agent.
SARMs stacks are the logical way to progress your usage if you
hit a plateau or are looking for something tougher hitting.
For instance, the spotlight of one might be lean, dry features, whereas the spotlight of
one other may be enhanced recovery. The most suppressive SARMs are essentially the most potent ones, particularly when they’re run for very long cycles.
The most powerful SARMs include YK-11, which we would suggest just for very advanced users.
Even although SARMs are incessantly marketed as
safer substitutes for steroids, they still
carry dangers.
One standout instance is Tirzepatide, which many consultants consider the next evolution in weight loss medicine.
These two well-liked compounds have taken the
health world by storm—and for good cause. They promise spectacular results
but work in utterly different ways. For the record, there are quite a couple of SARMs available
on the market, and some are stronger than others
— that means they;re each simpler and have more side effects.
At the same time, SARMs can keep away from binding to receptors that set off unwanted androgenic side effects.
This leaves many irrelevant androgen receptors untouched, unlike the non-selective exercise of anabolic steroids.
Non-selective steroidal drugs, referred to as anabolic androgenic
steroids (AAS), have been used for numerous medical purposes, but their side effects limit their use.
In 1998, researchers discovered a new class of non-steroidal compounds,
the SARMs. These compounds selectively stimulate the androgen receptor, providing potent
effects on bone and muscle to increase bone density and lean body mass while having minimal impression on reproductive tissues.
It might sound extreme, however shedding substantial fats on this stack is greater than attainable while gaining much muscle.
We’re speaking about 10 and even 15 pounds of fat loss by the end of the cycle and five or extra kilos
of gained muscle. The determining factor will be how strict and well-planned your
chopping food regimen is and the sort and intensity of exercises.
You may not need to acquire a lot muscle right here, so gear your workouts to
fats loss to form your outcomes accordingly. An various chopping cycle for novices could be to make use of Andarine instead of Ostarine.
Anabolic refers to their muscle-building effects, whereas androgenic refers
to their results on male traits. SARMs can be efficient for muscle development and efficiency,
however they are not as strong as steroids. They are sometimes most well-liked for
their probably fewer side effects and more targeted action. SARMs still must
undergo more intensive and rigorous medical trials as their long-term security, efficacy,
and total impression on health usually are not but as well-established as these
of anabolic steroids. Despite their vital benefits, anabolic steroids are usually not beneficial by most
professionals as a end result of their potential adverse effects.
Whichever complement you select, you should take it earlier than a
carbohydrate-rich meal to get probably the most unimaginable advantages.
If staying asleep all night is a problem, then magnesium, glycine, and vitamin B6 have lengthy been used
to solve this drawback. Some supplements include
all three; the label will provide the beneficial dosage.
At the time of writing, there are not any clinical trials of andarine
[3]. The increase was attributed to upregulated bile acid synthesis by a mechanism of increased expression of CYP8B1.
Additionally, low HDL cholesterol levels in both reported instances probably point out the shift of ldl cholesterol transport in the path
of bile acid synthesis, thus contributing to elevated intracellular content of poisonous bile acids.
Amongst muscle-building amateur athletes, SARMs (ligandrol or ostarine) and/or substances in PCT may trigger cholestatic liver injury with
prolonged recovery. Dosing is in the 7mg to 21mg vary,
with 14mg being the «sweet spot».
Nonetheless, SARMs are still under investigation and lack long-term safety knowledge.
Continued research and medical evaluation are crucial to understanding
their potential benefits and risks fully. SARMs might be
thought-about better than steroids for some customers
as a end result of their focused effects and doubtlessly fewer unwanted effects and their much
less regulated standing. The FDA has not accredited SARMs for
any use exterior of research, which means that those who choose
to make use of them are taking on potential health risks.
In studies, MK-677 was given at doses of as a lot as 50mg every day at
the high end. With that said, the belief that SARMs are «secure» is as wrong as a belief could be.
There are numerous false beliefs, similar to they do not shut you down (decreasing pure testosterone production), cause
pimples, increase hair loss, or have an result on your organs.
The 40-year-old athlete has competed in and won a number
of weightlifting and strongman competitions throughout his profession, and even broken world data.
One competitor estimates that solely about 1% ofstrongmen have by no means used anabolic
steroids. (Kazmaier thinksit’s closer to 50%.) Bruce Wilhelm,
a silver medalist inweightlifting on the ’76 Olympics and
the winner of the first twoWSM competitions, says,
«If you examined for drugs, you wouldn’thave a contest.»
Nevertheless, bench-pressing, squats, and deadlifts are three
compound exercises which are relied upon by renowned powerlifters like Zack George.
Different go-to activities when branching out the
strongman routine embody lunges, farmer’s walks, and the overhead press.
Leonid was born in 1956 within the USSR and set the world record for the clear and jerk
(266kg or 58.2 pounds) and whole (475 kg or 1,045 pounds) again in 1988,
a report that has stood for eons. Even although weightlifting tips changed and his record now not stands within the lifting federation,
none comes near equaling his power.
He’s the father of a younger daughter and has
another one on the way. Invited to World’s Strongest Man for the first
time in 2022, Hooper completed better than expected – eighth
overall, plus he gained his six-man warmth, which included four-time
champion Brian Shaw. It was the one major competitors the place Hooper didn’t make the rostrum.
It can be the primary video of an upcoming collection of movies masking the subject of hormones,
testosterone, and other anabolics.
Eddie’s crowning glory got here in 2017 when he was finally declared the World’s Strongest
Man, an accomplishment pinnacle for any critical strongman competitor.
Despite asserting his retirement from the World’s Strongest Man competitors proper after achieving the world title due
to medical considerations, Eddie ensured his legacy throughout the power sport would endure.
However, life away from the sporting arena was
something of a wrestle. The college didn’t come easy to Eddie,
expelled from Clayton Corridor Academy at 15, turning a doubtlessly life-altering curveball into
character-building fodder. The expulsion didn’t
deter him from changing into a successful member of society, opting
to dive into the world of work.
On their approach to Veteran’s Memorial Auditorium that night, for the ultimate event of the competition, the boys sat
quietly in a non-public coach, submerged in their thoughts.
They had the half-desperate look of troopers in a convoy, advancing
toward a beachhead. There wasn’t much trash speak or posturing at contests like this—the lifts had been daunting enough on their own—but I’d often seen them cheer and luxury each other between lifts,
and even offer recommendation. The year earlier than, on the
World’s Strongest Man, they needed to drag a twenty-two-thousand-pound Titan truck greater
than eighty feet down a highway. Shaw, who prided himself on fastidious
preparation, had ordered a pair of custom truck-pulling sneakers from England,
with high-friction soles. He would have gained the contest, had
he not given his spare pair to Björnsson, who beat him
by half a second. Not Like many strongmen who have a complete rest day, Eddie’s typical midweek interval would include cardio exercises,
yoga, and a session together with his physical therapist.
With exhibits like «Eddie Eats America,» «Beasted,» and contributions to the charming Historical Past Channel series «The Strongest Man in Historical Past,» Hall’s personality shone by way of.
For those who are thinking about strongman existence and fitness,
his YouTube channel is still a popular site.
In a shocking flip of events and proving his
braveness to tackle completely new challenges, Eddie stepped into the world of skilled boxing.
The defining occasion of his boxing stint got here when he squared off in opposition to
another strongman legend, Hafþór Júlíus Björnsson, famously
known as ‘The Mountain’ from Recreation of Thrones.
Hoeberl, an Austrianwho completed second (to a Magnus,
by the way) within the 1994 WSMand who might be the only
sports activities exec whose biceps oncemeasured greater than 25 inches, has already lured away one topname (a Magnus, by the way) from WSM.
However Frank professes not todevote even a second of
thought to Hoeberl’s group, and he sayshe believes ESPN viewers will blissfully tune in to
WSM nomatter which Samsons are spilling the sweat.
In 1990, Jón Páll got here to the 1990 World’s
Strongest Man injured, but after a valiant battle, received the
title for a document breaking fourth time. He also
won World Muscle Energy Traditional and Iceland’s Strongest Man. In 1986 World’s Strongest Man in Good, France,
Jón Páll gained his second title, beating Capes by four factors.
He shook the kinks from his arms and bounced on his toes like a boxer, then bent down to pick up
the body. It seemed, for a moment, as he charged up the slope, that he would possibly simply make it in time.
«But then you’re trying to carry on, and your grip begins to lose it, and it’s simply opening, opening, opening. I don’t know anything else.» He
was less than two feet from the top when the final strands
of his biceps tore free, and the frame came thudding down. He managed
one final, agonizing push to the end line, as blinded and enraged as
Samson in the temple.
Bjornsson, 30, turned to competing in strongman occasions after his dream of turning into knowledgeable basketball player ended when he twice broke his
proper ankle on the age of 19. Turning to weightlifting,
the now 6-foot-9, 440-pound native of Iceland was discovered
in a fitness center by countryman Magnus ver Magnusson, a four-time winner of the WSM competition.
Understanding that steroids are so accepted amongst strongmen, Philippi,feeling he’ll come across like a complaining moralist,
is evenreluctant to speak about not taking them. «How might I load up,then ask my guys [at UNLV] not to?»
is about all he’ll say.
