HCCI ENGINE WITH COMBUSTION-TAILORING CHAMBER

摘要

An internal combustion engine is adapted for operation with homogeneous combustion and compression ignition. The engine includes plural cylinders with the piston in each cylinder defining the main combustion chamber and connected to a crankshaft for reciprocating motion rotatably driving the crankshaft. An auxiliary combustion chamber and an inlet passage are formed in the engine head for each of the cylinders with a control valve for controlling communication between the main combustion chamber and the auxiliary combustion chamber and an inlet valve for controlling communication between the main combustion chamber and the inlet passage. The inlet valve is driven with rotation of the crankshaft, while the drive for the combustion control valve is independent of angular position of the crankshaft and has its own controller for timing its opening and closing to provide controlled homogeneous combustion.
