    摘要: A dual fuel engine is provided. The dual fuel engine includes an engine cylinder that is adapted to house a piston. A cylinder head is coupled with the engine cylinder. An inlet valve is adapted to inject a second fuel into the engine cylinder. A pre-combustion chamber is adapted to be coupled within the cylinder head to receive a first fuel via a micro-pilot fuel injector. As piston moves towards a top dead center pushing a portion of the second fuel into the pre-combustion chamber via a communication channel, the piston compresses the portion of the second fuel and the first fuel in the pre-combustion chamber for igniting the first fuel and combusting the second fuel. This generates a combustion flame. The pre-combustion chamber is adapted to allow the combustion flame to propagate from the pre-combustion chamber to the engine cylinder via the communication channel.

    摘要: A dual-fuel engine has a primary fuel supply and a secondary fuel supply, the primary and secondary fuels being arranged in use to mix with each other and with air for combustion in one or more cylinders of the engine. The supply of both the primary and secondary fuels is arranged to be actively managed in accordance with a desired engine performance characteristic by an electronic controller. In one arrangement the supply of a primary fuel is arranged to be actively reduced when a secondary fuel is supplied to the engine.

    摘要: A dual fuel engine (2) is provided which is supplied with diesel fuel and at least one secondary fuel, such as LPG. The engine (2) has a plurality of cylinders (4, 6, 8, 10) in which pistons reciprocate. Each cylinder has diesel injectors (4A, 6A, 8A, 10A) for injecting the diesel fuel into the cylinder during an appropriate stroke of the piston and an air inlet valve (4C, 6C, 8C, 10C) which opens during the appropriate stroke of the piston to permit air flow therethrough. Each cylinder is further provided with LPG injectors (4B, 6B, 8B, 10B) for injecting the secondary fuel into the cylinders. The LPG injectors are independent to and separate from the diesel fuel injectors. The LPG and diesel fuel injectors are also independently controlled.
