Title: Rotary piston engine of epitrochoid design - fuel injection and combustion occurs in two stages
Inventor: SIAK-HOO ONG
IPC: F02B53/02
Filed: 1975-01-24
Abstract: The engine is provided with two fuel injectors the first being the main fuel injector which produces a weak mixture incapable of being ignited by the high tension spark whilst the second injector situated close to the spark plug produces a rich mixture which is readily ignited by the spark occurring just before top dead centre causing a 'Start' flame to ignite the weak mixture. Various alternative positions for the main injector giving the relatively weak mixture are proposed. Two carburettors and two inlet ports may also be used working on the same principle. Alternatively only one injector could be used, situated close to the spark plug and giving first a weak fuel injection at the beginning of the compression stroke and a rich injection just before ignition. Piston lubrication oil is also injected with the auxiliary fuel and the spark plug bore has a forwards converging form to offset any plug point pollution.
