摘要： An internal combustion engine (100) comprises a fuel injection valve (21, 22) which supplies a first fuel having a higher self-ignitability than gasoline and a second fuel having a higher combustion speed than gasoline such that an air-fuel mixture containing the first fuel and the second fuel is formed in a combustion chamber (14), a spark plug (25) which ignites the air-fuel mixture, and a programmable controller (41) programmed to control supply proportions of the first fuel and the second fuel such that the ignited air-fuel mixture undergoes flame propagation combustion and then undergoes self-ignition combustion. Thus, a reduction in emissions can be achieved, and high thermal efficiency can be realized through the self-ignition combustion.

摘要： An internal combustion engine includes neighboring main and auxiliary combustion chambers that are separated by a partition wall including a communicating passage. Ignition of an air/fuel mixture in the auxiliary combustion chamber produces a fuel torch that is jetted into an air/fuel mixture in the main combustion chamber. Under a predetermined operation condition, timing for opening an intake valve is retarded relative to both the timing for closing an exhaust valve and the timing for top dead center of a piston on an exhaust stroke. By retarding the timing for opening the intake valve, residual gas in the auxiliary combustion that is left over from a previous cycle can be reduced.

摘要： A spark-ignition type internal combustion engine, including a main tank for storing a to-be-determined fuel having an unknown self-ignition property, an auxiliary tank for accumulating a reference fuel having a known self-ignition property, and a controller. The controller is programmed to supply to a combustion chamber a blended fuel prepared by blending the to-be-determined fuel and the reference fuel at a predetermined ratio, measure a self-ignition property of the blended fuel, and determine the unknown self-ignition property of the to-be-determined fuel based on the measured self-ignition property of the blended fuel, the known self-ignition property of the reference fuel and the ratio of the blended fuel. The controller is also programmed to introduce the to-be-determined fuel after the determination from the main tank to the auxiliary tank, and store the to-be-determined fuel in the auxiliary tank such that the to-be-determined fuel serves as a next reference fuel having a known self-ignition property.

摘要： An internal combustion engine, including a premixed mixture formation device that forms a premixed mixture of fuel and air in a combustion chamber, a fuel gas supply device that injects fuel gas directly into the combustion chamber, and an ignition device that ignites the fuel gas. The fuel gas supply device is configured to inject the fuel gas into the premixed mixture near a top dead center of a compression stroke such that a spray of the fuel gas passes through a firing position of the ignition device, to produce the spray of the fuel gas in a predetermined area substantially extending from one end of a cylinder bore to the other end as viewed in a cylinder-bore direction defined by a centerline of the cylinder bore. The ignition device is configured to directly ignite the spray of the fuel gas and to ignite and burn the premixed mixture by way of flame propagation along the spray of the fuel gas.
