Problems solved by technology

[0006] In fact, there is a swing angle β in the connecting rod of the traditional internal combustion engine, and the piston stroke S is also short, usually 0.9 to 1.2 times the cylinder diameter D, and the gas expansion force F P Not fully utilized, high exhaust gas pressure (calorific value) is discharged out of the cylinder, resulting in low heat engine conversion efficiency (26-34%), and the exhaust gas takes away about 30% of the heat energy, causing a lot of noise

Abstract

An internal combustion engine with low oil consumption and low noise is an improvement to traditional internal combustion engine technology in such areas as additional straight-line reciprocating unit, delay air vlave mechanism, self-boosting technique and the cylinder sleeve made of composite material, resulting in a suspension-type straight-line reciprocating movement mechanism with no lateral abrasion of piston, constant specific compression stroke and increased specific expansion stroke. The full over-oxygen combustion of fuel can be ensured. Its advantages include high reliability and heat power, less residual pressure and waste gas and low noise of exhaust.

Description

Technical field: [0001] The invention relates to a variable capacity engine, in particular to an internal combustion engine with low fuel consumption and low noise. Background technique: [0002] As we all know, in the crankshaft and connecting rod reciprocating piston internal combustion engines in service, due to the continuous rotation of the crankshaft, the connecting rod sleeved on the crank journal and connected to the piston must have a swing angle β, and the effective force decreases with the increase of the swing angle. Harmful side wear of the cylinder wall increases, calculated by the conventional empirical formula, the total force P ∑ Will be decomposed into the connecting rod force P along the connecting rod direction k and the lateral force P perpendicular to the cylinder wall n . [0003] P k =P ∑ · COSβ, Pn=P ∑ · tamβ. [0004] (See "New Aluminum Piston", published by National Defense Industry Press in August 1999, p6) [0005] It can be seen th...
