Abstract: An internal combustion engine having one or more power pistons (17) reciprocating in one or more cylinders (13) has at least one fuel inlet valve (14) of the piston type at each cylinder. An inlet valve sleeve (32) has an open end at the top of the cylinder and has fuel inlet ports (37) situated away from the cylinder. A valve piston (39) in the sleeve is movable towards the cylinder and away from the cylinder by an actuator system to open and close the valve. The actuator system varies timing and duration of the open periods of the valve to control engine power output thereby eliminating any need for a throttle valve and its attendant power losses. Valve piston (39) movement also varies the effective compression ratio in the engine cylinder as a function of power output thereby further increasing fuel efficiency.
