Understanding Engines: How a Diesel Engine Works?

Have you ever wondered what is the difference between a gasoline engine and a diesel engine? Besides the difference in noise that you hear when the diesel engine is running, there is a greater difference.

In a diesel engine, fuel is sprayed into the combustion chamber with the injector nozzle. The air in each chamber must be placed under very high pressure so that it is hot enough to ignite. Diesel itself is not flammable so it must be put under some sort of force. You can browse www.strictlydiesel.com/p-3654-gearhead-60l-sct-tunes.aspx to know more about the best 6.0 powerstroke tuners.

Many people turn on the ignition before driving a car to warm the engine. This might be useful in very cold weather conditions. Turning the key in the ignition system is the beginning of the whole process. After the key is turned, fuel is injected into the cylinder under tremendous pressure. This allows the air to heat itself.

Earlier versions of diesel engines needed incandescent spark plugs to heat the gas to produce an efficient drive. At present, gas or air heats up so fast those incandescent plugs are not as necessary before, but these plugs are still there to control emissions.

The diesel fuel then passes through the filter to be cleaned before it gets to the injector nozzle. It is important to maintain the filter because contamination is common in this type of fuel and blockages can occur.

In fuel injectors, a high and constant pressure of 23,500 psi needs to be applied when releasing fuel into the cylinder. Fuel is sprayed into the chamber with the Engine Control Unit (ECU). This ECU will determine the pressure that needs to be applied for the spraying process.

Most diesel engines have turbochargers mounted for greater power and pressure. Turbochargers also save the amount of fuel used in one cycle. With the turbocharger installed, diesel engine power has increased by more than forty percent.
