Document Type and Number:
Japanese Patent JP2954350
Kind Code:
B2
Abstract:
A system (100) for controlling operational modes of an engine (102) including valve and injection events, in which the engine (102) comprises a plurality of cylinders (104) having an intake and exhaust valve (220,222), an injector (224), a chamber and an intake and exhaust port. The plurality of cylinders (104) are connected by an intake and exhaust manifold. The system (100) comprises a cylinder control unit (108) for independently governing an operational mode of each of the cylinders. The cylinder control unit (108) comprises a valve control unit for controlling the operation of the intake and exhaust valves. The cylinder control unit (108) also controls opening and closing of the intake and exhaust valves (220,222) in accordance with the independently governed operational mode of each cylinder. The cylinder control unit (108) further comprises an injector control unit for controlling the operation of each of the injectors (224). The injector control unit controls fuel injection timing of each of the injectors (224), independently of the operation of the intake and exhaust valves (220,222). The cylinder control unit (108) independently controls each of the cylinders (104) to control the valve and injection events to achieve a plurality of operational modes for the engine (102).
