1. Introduction to turbochargers

A turbocharger is a type of air compressor that increases intake by compressing air. The inertia impulse of the exhaust gas discharged by the engine is used to drive the turbine inside the turbine chamber, which in turn drives a coaxial impeller, which compresses the air sent by the air filter pipeline and pressurizes it into the cylinder.

When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The pressure and density of the air increase, which can burn more fuel. Correspondingly, increasing the fuel quantity and adjusting the engine speed can increase the output power of the engine.

2. Advantages of turbochargers

Increasing engine power: While the engine displacement remains unchanged, increasing the intake air density allows the engine to inject more fuel, thereby increasing the engine's power. After installing a turbocharger, the engine's power and torque should increase by 20% to 30%.

Improving engine emissions: Turbocharged engines reduce the emissions of harmful components such as particulate matter and nitrogen oxides in engine exhaust by improving the combustion efficiency of the engine. It is an indispensable configuration for diesel engines to meet Euro 2 or above emission standards.

The function of providing plateau compensation: In some high-altitude areas, the higher the altitude, the rarer the air. Engines with turbochargers can overcome the power reduction caused by the rarefied plateau air.

Improving fuel economy and reducing fuel consumption: Due to the better combustion performance of engines with turbochargers, fuel can be saved by 3% -5%.
