| 摘要 |
A rotary combustion engine designed for operation as a stratified-charge engine by providing the engine with two intake passages, one an unthrottled passage for air only and the other for a very-rich, carburetor-controlled, fuel-air mixture such that the over-all charge is relatively lean. The two intake passages are arranged so that the fuel-rich mixture occupies the trailing portion of each engine working chamber when the mixture in the chamber is ignited and the spark plug for initiating combustion is disposed so that it fires in this fuel-rich region.
