Problems solved by technology

As such, spark-ignition engines suffer from various combustion problems: a relatively high probability of misfire, the need for long flame spread times, and the phenomenon of knocking caused by self-ignition of the terminal gases before they reach the flame front

Abstract

The invention discloses a spark ignition engine and a control method thereof. The spark ignition engine includes a main combustion chamber configured to suction a mixture through an intake port, a pre-chamber configured to communicate with the main combustion chamber, an auxiliary cylinder configured to communicate with the main combustion chamber via the pre-chamber, an auxiliary intake passage connecting the auxiliary cylinder and the intake port, an auxiliary piston, and a spark plug configured to ignite the mixture in the pre-chamber. The auxiliary piston is configured to slidably reciprocate in the auxiliary cylinder such that the mixture is suctioned from the intake port via the auxiliary intake passage and the mixture is discharged to the main combustion chamber via the pre-chamber.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2012-0142055 filed in the Korean Intellectual Property Office on December 7, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The present inventive concept relates generally to a spark ignition engine, and more particularly, to a spark ignition engine in which an ignited flame propagates to combust a mixture before reaching a combustion chamber. Background technique [0004] Internal combustion engines can be classified into spark ignition engines, such as gasoline engines, which are equipped with a spark plug and promote the combustion of the mixture by a separate ignition spark, and compression ignition engines, which inject fuel into the combustion chamber Combustion is facilitated by the spontaneous combustion of fuel in compressed air. [0005] In a spark ignition ...
