1 rebuild the combustion chamber and increase the compression ratio. The diesel engine energy-saving reform technology adopts the modified piston, so that the volume of the main combustion chamber is reduced, and the compression ratio is increased; the amount of gas inside the cylinder is reduced, and the utilization rate of air in the main combustion chamber is increased. 2 improve the law of oil supply. The measure is: to use an improved plunger pair with an increased diameter to maintain the oil supply and reduce the oil supply rotation angle. 3 Reduce the friction loss of the sports pair. The measures are: using modified pistons, changing three air rings, two oil rings to three air rings, and one oil ring; adjusting the dimensional tolerances of the main friction parts.
