Diesel engines 2

Let’s talk about gas trucks vs. diesel engines. Gas engines may provide more horsepower but diesel engines offer more torque for acceleration and pulling power. All of the Big Three’s diesel engines are rated more than 600 lb-ft of torque, while their biggest gas engine is rated at 455 lb-ft. This advantage is achieved through a number of dynamics that make all diesels different from gasoline engines, beginning with the fuel. Diesel fuel is heavier and carries more carbon atoms than gasoline, that has about percent more energy density. Since engines convert heat energy from the fuel into mechanical energy, diesels offer more power and miles per gallon. Today’s truck most people want pulling power for towing, and diesel offers that extra power. Horse trailers are now bigger, with some even featuring living quarters. Travel trailers increase in size and weight. Race and show cars are being towed in bigger trailers to make sure you have the tools, supplies, and other needs. And everyone wants a bigger boat. With Interstate speed limits back up to 70 mph and higher, drivers towing these big trailers need more pulling power to enter on-ramps safely and maintain speed on steep mountain roads. Also to make sure they have the horsepower and have the life span of an engine to do all the work that some gas engines can not do.

Some engines are stock and some people that want more performance they program it and get what they want for max power. Key to programming such delicate fuel events is a common-rail fuel-injection system that supplies fuel at pressures from 2,000 psi up to more than 23,000 psi. Gas engines with electronic fuel injection run at 40 to 60 psi. Older diesels had separate fuel lines from the fuel pump to each injector. The pressure and injection timing were dependent on engine speed, which sometimes led to a fuel-delivery lag at high engine speeds. Today, a common-rail system links all the injectors to a feed line that is independent of engine speed, allowing the engine-management computer to control fuel exactly as programmed by the engineers. In 2017 all Alison transmissions are going in the newer trucks because they are so reliable and have very good gearing and are able to haul a heavy load without having any issues. Alison’s are the strongest yet most and best selling transmission out there. Most newer trucks are starting to do bigger and better transmissions like Alison because they are all around the best make right now.
