Title: Spark ignition internal combustion engine
Inventor: TERACHI ATSUSHI
IPC: F02P15/08
Filed: 2008-10-08
Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent knocking in a spark ignition internal combustion engine and improve thermal efficiency.  <P>SOLUTION: This internal combustion engine includes a pair of exhaust valves 8 and a pair of intake valves 7, a first spark plug 9 at roughly the center of a combustion chamber 1, and a tumble control valve variably controlling the intensity of tumble flow. Although ignition with the first ignition plug 9 is done at prescribed ignition timing, flame propagation 21 after spark ignition is distorted with a pair of vortexes T1, T2 due to a tumble flow, and an end gas zone 22 remains near the intake valve 7 of the combustion chamber 1. A second ignition plug 12 is arranged to correspond the end gas zone 22, and spark ignition combustion is done before knocking occurs by igniting at a suitable delay in phase difference with the first spark plug 9. Knocking is surely avoided by actively forming the end gas zone 22.  <P>COPYRIGHT: (C)2010,JPO&INPIT
