Energy-saving piston for gas engine

Abstract

The invention discloses an energy-saving piston for a gas engine, and solves the technical problem of the heavy piston in the prior art. The technical scheme is that the energy-saving piston for the gas engine comprises a piston top surface, a piston combustion chamber, a piston head, a piston ring groove, a piston skirt, a wedge-shaped pin seat arranged in the cavity of the piston, a piston pin hole provided with a clamp ring groove, and a piston pin, wherein the ratio of the height to the outside diameter of the piston is (1-1.035):1; and the piston pin comprises a piston pin outer cycle, a piston pin inner hole and a conical surface formed in the piston pin inner hole, wherein the ratio of the length of the piston pin to the diameter of the piston pin outer circle is (1.96-2.05):1. The piston and the piston pin provided by the invention are particularly used for a T6114ZLQ-type gas engine, wherein the diameter of a working cylinder is 114 mm, the number of the cylinders is 6, and the displacement is 8L and 9L; the piston is light in weight, reasonable in structure, and low in invalid friction power loss; and the aims of improving power, reducing fuel oil and engine oil consumption, saving energy resources, and reducing pollution and emission are fulfilled.

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, especi...

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
