Why is the power of the generator set up to reach the power of rated standards

Why is the power generator set that does not reach the power of the rated standard, and the load is lowered. The following power shortage failure causes and solutions:
DI 1: low fuel pressure. Take the fuel tank in the fuel tank. Check the oil supply pipeline between the fuel tank to the oil pump, there is no leakage or diagonally, and the air entering the fuel system, the fuel control valve is card letter, sticking or expires. Check the fuel pressure. When the engine is fully loaded, the fuel oil pump outlet pressure zui should be 415 kPa. If the fuel pressure is lower than the above pressure, the fuel filter is replaced. When the oil pressure is still low, the fuel oil pump is required.
Second: The valve gap is wrong. Adjust the valve clearance.
Third: The fuel quality is poor. Drain the fuel tank, replace the fuel filter. Add high quality fuel to the fuel tank.
Fourth: The power is too low. Adjust the engine power by the technical specifications on the engine brand.
Fifth: Turbo pressurium accumulation. Check the turbocharger and repair if necessary.
Sixth: Check the intake manifold pressure. Check the air filter has a metapulsion.
Seventh: Air filter is blocked.
