IC engine with premixed and preburning jetting inside cylinder

Abstract

An internal combustion engine with a pre-blending and pre-combustion chamber comprises a normal cylinder, whereon the cylinder head installed a pre-blending and pre-combustion chamber, whereon the chamber installed spark plug, fuel inlet, air inlet, air valve driving device, cooling channel, fuel gas volume adjusting valve, air volume adjusting valve. The chamber links to the cylinder directly. Through a small amount of pre-combusted fuel gas to ignite the blended gas in the cylinder to realize the maximum combustion pressure to decrease the noise and exhaustion then to increase the efficiency of the engine.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a gas internal combustion engine with pre-mixing and pre-combustion in-cylinder injection. Background technique [0002] With the increasingly tense global energy sources and people's calls for environmental protection, people put forward higher requirements for the application fields and emissions of internal combustion engines, and internal combustion engines are more involved in the application of low calorific value gaseous fuels, which are usually produced by The intake pipe of the internal combustion engine is sent into the cylinder. Some internal combustion engines mix fuel gas with air before the intake pipe, while some internal combustion engines mix in the intake passage of the cylinder head. These working methods will more or less cause gas explosion in the intake pipe. Threat to the safety of the operator and prevent the engine from functioning properly. In addition, ...
