According to Gale Banks Engineering, diesel engines have more torque than certain other engines due to cylinder pressure, turbocharger boost and stroke length. The fact that diesels possess these characteristics allows them to perform at a higher level than other gasoline engines.Know More
Typically, diesels create a longer stroke, specifically because the pistons of the engine move at fast speeds, thus creating longer strokes; this feature results in higher torque. Furthermore, due to higher cylinder pressure and increased pressure on the crankshaft, the diesel engine is further effective in creating more torque. In addition, diesel fuel has around 10 to 11 percent more energy per gallon than gasoline.
Diesel engines are also known for burning fuel more efficiently than a gasoline engine, which allows the engine to deliver more power more effectively. Additionally, a diesel engine compresses just air, to a very high temperature and pressure, so that the diesel fuel ignites without a spark when injected. In contrast, gasoline engines compress a fuel-air mixture, which then has to be ignited by a spark, decreasing its ability to create torque. Gale Banks Engineering Incorporated supports the idea that despite cost, diesel fuel is becoming more popular because of its efficiency.Learn More
Most knocks come from the ignition or the injector nailing. Fuel injectors can also cause a knocking noise, especially in older diesel vehicles.Full Answer >
A petrol, or gasoline, engine is very similar to a diesel engine but is generally lighter and uses a spark ignition system rather than the diesel's compression ignition system. Diesel engines are exposed to greater pressures and must be built more heavily than petrol engines for the same capacity. Both petrol and diesel are refined crude oil products, but diesel is less refined and is very similar to heating oil.Full Answer >
Black smoke from a diesel engine is caused by an unbalanced air-to-fuel ratio. Either not enough oxygen is being added to burn the fuel, or too much fuel is in the mix. Black smoke is one of the most common smoke issues for diesel vehicles.Full Answer >
There are several theories about why fire engines are red. One theory suggests that fire trucks were first painted red back in the 1800s when fire brigades took so much pride in their trucks that they wanted them to stand out and feature the most regal and expensive color, which at the time was red.Full Answer >
