Combustion chamber of internal combustion engine

Abstract

There is disclosed a combustion chamber of internal-combustion engines, which includes a combustion chamber wall body, a combustion chamber piston in the wall body cavity and a mechanism disposed outside the bottom of the combustion chamber piston capable of making the combustion chamber piston be in reciprocating motion along the centre-line of the combustion chamber. Using the inventive structure can eliminate the volume of the combustion chamber and reduce the residual waste gas in the combustion chamber via the movement of the combustion chamber piston at the end of the instroke.

Description

technical field [0001] The invention relates to a combustion chamber of an internal combustion engine. Background technique [0002] The combustion chamber of an internal combustion engine is the space in the cylinder that accommodates the combustible mixture for combustion and heat release. It is generally divided into two categories: unified combustion chamber and separate combustion chamber. The common problem of these traditional internal combustion engine combustion chambers is that since the combustion chamber is fixed and immutable and occupies a fixed volume, it is impossible to exhaust the exhaust gas in the combustion chamber at the end of the exhaust stroke, resulting in the exhaust gas remaining in the combustion chamber There is such a record in the first chapter, page 17, of "Automobile Structure" published by People's Communications Publishing House: "Because the combustion chamber occupies a certain volume, it is impossible to exhaust the exhaust gas at the e...

Problems solved by technology

The common problem of these traditional internal combustion engine combustion chambers is that since the combustion chamber is fixed and immutable and occupies a fixed volume, it is impossible to exhaust the exhaust gas in the combustion chamber at the end of the exhaust stroke, resulting in the exhaust gas remaining in the combustion chamber There is such a record in the first chapter, page 17, of "Automobile Structure" published by People's Communications Publishing House: "Because the combustion chamber occupies a certain volume, it is impossible to exhaust the exhaust gas at the end of the exhaust stroke. This part The exhaust gas left behind is called residual exhaust gas"

It can be seen that since the combustion chamber occupies a fixed volume, the technical problem of residual exhaust gas is caused.
