Energy-saving piston for gas engine

Abstract

The energy-saving piston used for gas engines solves the technical problem of heavy piston weight in the prior art. The technical solution adopted is to include piston top surface, piston combustion chamber, piston head, piston ring groove, piston skirt, and The wedge-shaped pin seat, the piston pin hole with the snap ring groove, and the piston pin set in the inner cavity of the piston, the key is: the ratio of the height to the outer diameter of the piston is (1~1.035): 1, and the The piston pin includes the outer circle of the piston pin, the inner hole of the piston pin, and the tapered surface set in the inner hole of the piston pin. The ratio of the length of the piston pin to the diameter of the outer circle of the piston pin is (1.96~2.05): 1. , especially for the T6114ZLQ gas engine with a working cylinder diameter of 114mm, a cylinder number of 6 cylinders, and a displacement of 8L or 9L. The purpose of consumption, energy saving, pollution and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and relates to an assembly part of a high-speed medium-heavy gas engine, specifically an energy-saving piston for a T6114ZLQ gas engine, especially suitable for a working cylinder with a diameter of 114 mm and a number of cylinders of 6 Cylinder, T6114ZLQ gas engine with a displacement of 8L and 9L. Background technique [0002] Gas engines are mainly used in mechanical equipment such as automobiles, ships, construction machinery, transportation machinery, generator sets, etc. Pistons and piston pins are one of the most critical parts in the engine, and they are the "heart" of the engine, which burns gas The generated explosive pressure is transmitted to the crankshaft through the crank connecting rod to do work and form power. [0003] Gas engines, especially CNG engines, have superior emissions, economy, and relatively appropriate power, leading to their wider application, especially...

AI Technical Summary

Problems solved by technology

The height of the piston with this structure is high, the wall of the pin hole is thick, and the weight will naturally be large, resulting in a large reciprocating inertial force in the working motion, more frictional work loss, lower effective power, high gas consumption and oil consumption, and low power and economy. There are gaps and deficiencies in energy-saving and environmental protection performance
