Cylinder cover with double sparking plugs

Abstract

The invention discloses a double sparking plug cylinder cap, which comprises at least one spherical combustion chamber. The spherical combustion chamber is provided with an air inlet, an air outlet, a first sparking plug hole and a second sparking plug hole, wherein, the air inlet is communicated with an air intake passage, and the air outlet is communicated with an air drain passage. The invention is characterized in that: a burbling piece for disturbing flow is arranged near each sparking plug hole on the circumference of the base plane of the combustion chamber. Each burbling piece has a burbling surface on the base plane of the combustion chamber, and the projection of each burbling piece on the base plane is an obtuse triangle. As the invention adopts two sparking plugs for ignition,the flame travel is reduced and accordingly the combustion time is also reduced, thereby enabling adoption of greater compression ration to improve the economical efficiency of an engine. As one burbling piece for disturbing flow is arranged near each sparking plug hole on the circumference of the base plane of the combustion chamber, the combustion chamber is designed into a double burbling typecombustion chamber, thereby further improving combustion gas distribution in the combustion chamber and increasing combustion stability. The invention is applicable to various combustion engines.

Description

technical field [0001] The invention relates to an engine cylinder head, in particular to a double spark plug cylinder head. Background technique [0002] The main function of the cylinder head is to close the upper part of the cylinder and form the combustion chamber together with the top of the piston and the cylinder wall. There is a cooling water jacket inside the cylinder head. The cylinder head with overhead valves has intake and exhaust valve seats, valve guide holes and intake and exhaust passages. [0003] At present, the known gasoline engine uses a spark plug to ignite and burn the mixed gas, the flame propagation distance is long, the combustion time is long, the thermal efficiency is low, and it is easy to knock, so the compression ratio of the engine is limited, resulting in poor economy of the engine. At the same time, because the ignition advance angle needs to be advanced, the exhaust temperature is not high, which is not conducive to the light-off of the ...

AI Technical Summary

Problems solved by technology

Its shortcomings are that the distribution of gas in the combustion chamber is not reasonable enough, resulting in insufficient combustion characteristics, and the arrangement of spark plugs is not reasonable enough, and it does not involve the specific cylinder head structure of the dual-spark plug engine
