Abstract: A low pressure fuel injection system for a two cycle internal combustion engine. Fuel is introduced into the combustion chamber during the intake cycle from a cavity in the wall of the combustion chamber supplied with fuel by metering apparatus that controls the flow of fuel in accordance with engine demand. The fuel is compressibly accumulated when the cavity is covered by the piston during the compression and combustion cycles. As the piston moves into the fuel intake cycle, the cavity is opened and the fuel charge is discharged therefrom and swept out by the flow of intake air for subsequent vaporization and combustion.
