The role of the diesel engine turbocharger is by using the energy of the exhaust gas to compress the intake air and increase the intake air volume. And the high-density mixture is sent to the combustion chamber for combustion to improve the output power of the engine, increase the torque of the engine, and thereby increase the engine power.
1. Increase the engine power per liter. When 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 other hand, under the same power output requirement, the cylinder bore of the engine could be reduced, and the volume and weight of the engine could 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 for example particulate matter and nitrogen oxides in the exhaust gas of the engine. It is an indispensable configuration for diesel engines to meet the emission standards above Euro II.
3. Provide plateau compensation function. In some high-altitude areas, the bigger the altitude, the thinner the air, and the engine with a turbocharger can overcome the energy drop of the engine caused by the thin air on the plateau.
4. Improve fuel economy and reduce fuel consumption. As the combustion performance of the engine with turbocharger is way better, it could save fuel by 3%-5%.
