Where is the high pressure oil pump:
The high-pressure oil pump is just above the engine and is usually driven by the camshaft.
Generally, after opening the engine cover, you can see the high-pressure oil pump on the engine.
The high-pressure fuel pump can pressurize the gasoline delivered by the electronic fuel pump, so that the fuel injector in the cylinder can inject gasoline smoothly.
Direct injection engines must use high injection pressures because the pressure in the engine cylinders is very high. If you don't use high injection pressure, the gasoline will not come out.
The direct injection engine has a higher injection pressure, so that the gasoline atomization will be more thorough, and the air can be fully mixed with gasoline.
The fuel economy and power of the direct injection engine are better.
Many turbocharged and naturally aspirated engines are equipped with direct injection technology.
Generally, engines powered by in-cylinder direct injection technology are stronger and more fuel-efficient than engines powered by multi-point injection technology.
Direct injection engines also have disadvantages. The combustion chamber of this engine is more prone to carbon deposits, and the valves are also prone to carbon deposits.
It is recommended that car owners who use in-cylinder direct injection engines clean up carbon deposits regularly. The walnut sand cleaning method is an effective method to clean up carbon deposits, and the effect is obvious.
Carbon deposits are more harmful to the engine.
The following items should be paid attention to during the assembly process of the high pressure oil pump:
1) The positioning of the fuel injection pump control sleeve.
2) The installation mark on the plunger control wall of the fuel injection pump faces the window.
3) The meshing position of the oil quantity control rack of the fuel injection pump and the oil quantity control ring gear should be centered.
