The role of the diesel engine turbocharger is to use the energy of the exhaust gas to compress the intake air and raise the intake air volume. And the high-density mixture is sent to the combustion chamber for combustion to increase the output power of the engine, raise the torque of the engine, and thereby raise the engine power.
1. Raise the engine power per liter. Once the engine displacement remains exactly the same, the engine can inject more fuel by increasing the intake air density, thereby increasing the energy of the engine. The power and torque of the engine after adding a supercharger should be increased by 20% to 30%. . On the contrary, under the same power output requirement, the cylinder bore of the engine could be reduced, and the quantity and weight of the engine can be reduced.
2. Improve engine emissions. The turbocharger engine improves the combustion efficiency of the engine and reduces the emission of harmful components such as particulate matter and nitrogen oxides in the exhaust gas of the engine. It really is an essential configuration for diesel engines to meet the emission standards above Euro II.
3. Provide plateau compensation function. In a few high-altitude areas, the bigger the altitude, the thinner the air, and the engine with a turbocharger can overcome the power drop of the engine due to the nothing on the plateau.
4. Improve fuel economy and reduce fuel consumption. Because the combustion performance of the engine with turbocharger is way better, it could save fuel by 3%-5%.
