The fuel system of the traditional engine is injected through the air intake. By opening the valve, the fuel mixture enters the combustion chamber and is ignited by the spark plug to release energy. The direct injection system injects gasoline directly into the combustion chamber, and the fuel is injected through the multi-hole injector, and its ECU can accurately control the fuel injection quantity to make it reach the best working state.

Matters needing attention of in-cylinder direct injection turbocharged engine

Keep the turbine clean: This mainly refers to changing the oil and air filter. Changing oil is the maintenance of every car. Engine oil can be said to be the blood of the engine. The working environment of turbocharged engine is harsh, and the lubrication of engine oil is indispensable. It is more important to change the oil regularly.

The oil change interval determines the quality of the oil you use. The replacement cycle of mineral engine oil, semi-synthetic engine oil engine oil and all-synthetic engine oil engine oil is different. The replacement cycle of mineral oil is 5000km, that of semi-synthetic engine oil oil is 7500km, and that of synthetic engine oil is about 10000km.
