How normal is the car oil pressure?

Usually, the gasoline pressure of an automobile is about 280kpa, and the gasoline pressure of an engine equipped with in-cylinder direct injection technology can be higher. There are three kinds of fuel injection methods for automobiles, namely, in-cylinder direct injection, multi-point injection and mixed injection. The engine injector equipped with multi-point injection technology is located in the intake manifold and the engine injector equipped with in-cylinder direct injection technology is located in the cylinder. Mixed injection refers to direct injection and multi-point injection in the engine cylinder. The engine with mixed injection technology can choose different fuel injection modes under different working conditions, thus improving the power and efficiency of the engine. The fuel injection pressure of the engine equipped with in-cylinder direct injection technology is relatively high, but the in-cylinder pressure of the engine is relatively high. If the fuel injection pressure is low, the fuel cannot be injected into the combustion chamber normally. In addition, increasing the injection pressure can make gasoline atomization more thorough, make gasoline and air fully mixed, and improve the power and efficiency of the engine. Most automobile engines basically adopt in-cylinder direct injection technology. Before the emergence of EFI technology, automobile engines used carburetor to supply oil. Carburetor engine is an old-fashioned engine. Carburetors have high exhaust emissions, insufficient in-cylinder combustion, and the power is not necessarily the same as that of EFI engines.
