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 about Motion & Mechanics
The company that owns Cummins diesel engines is Cummins Inc., a public company that is listed on the stock market. It is listed on the New York Stock Exchange, and most of its shares are owned by institutional shareholders.Full Answer >
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 >
Diesel engine servicing includes an oil change, inspection of the glow plugs, examination of the gaskets and attachment bolts and cleaning or replacement of the fuel and air filters. Regular maintenance is essential for vehicle safety, engine longevity and fuel efficiency. CarsDirect also recommends topping off each fill-up with a bottle of purifying diesel engine treatment, which prevents accumulation of sediments and impurities.Full Answer >
