ABSTRACT:
Stratified charge four-stroke-cycle internal combustion engine with fuel injection and spark-ignition of the type wherein stratification and initial combustion occurs in a combustion chamber auxiliary to the variable volume space in the engine cylinder between the piston and the cylinder head. Unique aspirating passage means communicating between the auxiliary chamber and the variable volume space conducts and causes air entering the chamber at one end, pursuant to the piston's compression stroke, to form a substantially non-turbulent air column rotating about the chamber axis and acretively compressed, by continued entry of air, toward and against the opposite end of the chamber. Fuel is injected into air initially in the chamber and that initially entering through the aspirating passage to mix with such air to form a spark-ignitable air-fuel mixture compressed against said other chamber end. The remaining air forced into the chamber pursuant to the compression stroke comprises a substantially discrete mass creating the desired compression of the chamber contents for spark-ignition and combustion of the fuel.
