Cylinder cover with double sparking plugs

Abstract

The invention discloses a cylinder cover with double sparking plugs. The cylinder head comprises an air cylinder head and at least one combustion chamber arranged on the air cylinder head. An air inlet is formed in one side in the combustion chamber while an exhaust port is formed in the other side in the combustion chamber; the air inlet communicates to an air inlet duct formed in the air cylinder head, and the exhaust port communicates to an exhaust duct formed in the air cylinder head; a first sparking plug hole and a second sparking plug hole are also formed in the combustion chamber, andthe first sparking hole is formed in the middle position of a region on one side of the air inlet and the exhaust port and inclines toward the exhaust duct; the second sparking plug hole is formed inthe other side of the combustion chamber relative to the first sparking plug hole and inclines toward the air inlet duct. The cylinder cover disclosed by the invention has the advantages of being simple in structure and convenient to process. By means of symmetrical ignition of double sparking plugs and a flow turbulent device, gas is uniformly distributed, so that the combustion area is increased, and the explosive force is increased obviously. Combustion is more full and complete, emission is cleaner and the ignition safety coefficient is high.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a cylinder head with double spark plugs. Background technique [0002] At present, the known gasoline engine uses a spark plug to ignite and combust 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. Therefore, the increase of the compression ratio of the engine is limited, resulting in poor economy of the engine. [0003] Chinese patent 200520006166.0 discloses a parallel and symmetrical double spark plug combustion chamber. Its technical solution consists of a cylinder head, a cylinder body and a piston. Two spark plugs are symmetrically installed on the upper end of the cylinder head and extend into the combustion chamber. Its shortcomings are that the distribution of gas in the combustion chamber is not reasonable enough, resulting in insufficient combustion characteristics, a...
