  • Internal combustion engine with delayed torch ignition of oil fuel charge
    Patent number: 4091772
    Abstract: A primarily oil-fueled engine is disclosed in which the engine compression ratio is established well below the level at which compression ignition of oil fuel will occur and in which the oil fuel charge is ignited by the discharge from a spark ignited, gas-fueled precombustion chamber. The compression ratio and peak firing pressures are similar to those encountered in a gas-fueled engine.
