    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.

A fuel supply device supplies fuel to the main combustion chamber and the auxiliary combustion chamber. A mixture forming device forms a mixture of air and the supplied fuel in the main combustion chamber, away from the partition wall before ignition. An ignition device ignites the fuel in the auxiliary combustion chamber, propelling an ejecting torch flame into the mixture of air and fuel in the main combustion chamber through the injection hole, thereby burning the mixture of air and fuel in the main combustion chamber.

    摘要： An internal combustion engine system, including a primary fuel tank that stores a fuel, a fuel reformer that reforms the fuel from the primary fuel tank, a secondary fuel tank that stores the fuel reformed by the fuel reformer, a fuel injection device that injects the fuel that is selectably supplied from either the primary fuel tank or secondary fuel tank into a combustion chamber, a sensor that detects the quantity of fuel remaining in the secondary fuel tank, and a control device that sets and outputs a load and revolution speed of the engine. The control device is configured to set the engine load and engine revolution speed according to a request output determined based upon an operation performed by an operator. The engine load and engine revolution speed when the quantity of fuel remaining in the secondary fuel tank is more than a predetermined value, are set different than when the quantity of fuel remaining in the secondary fuel tank is less than the predetermined value.
