摘要： An engine having a cylinder, a piston slideably received in the cylinder, a crankshaft connected to the piston, and a multi-link piston crank mechanism. The multi-link piston crank mechanism controls movement of the piston such that an acceleration of the piston at top dead center is less than an acceleration of the piston at bottom dead center. A determining device determines an operating condition of the engine. A combustion mode control device controls the engine to operate at an air-fuel ratio leaner than a stoichiometric air-fuel ratio when the determining device determines that the operating condition of the engine is in a predetermined operating region.

摘要： An internal combustion engine includes a main combustion chamber and a small auxiliary combustion chamber. The main chamber is formed by a cylinder, the undersurface of a cylinder head, and the crown of a piston. A main ignition unit is disposed in the cylinder head, including a main body and a spark plug. The auxiliary chamber is formed within the main ignition unit. The main and auxiliary chambers are connected via a communication passage. The piston crown includes a cavity. When a fuel injection valve sprays fuel into the cavity on compression stroke, a tumble flow of fuel gas is generated to locally form a relatively rich air-fuel mixture near the communication passage. The air-fuel mixture partly flows into the auxiliary chamber as the piston travels upwardly. The air-fuel mixture in the auxiliary chamber is ignited by the spark plug so that a combustion flame propagates into the main chamber.

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 (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.
