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： A reforming catalyst (6) induces an isomerization reforming reaction and a decomposition reforming reaction of a gasoline fuel. Injectors (27, 33, 35, 36) supply an isomerized fuel generated by the isomerization reforming reaction and a decomposed fuel generated by the decomposition reforming reaction respectively to the internal combustion engine (1). The ratio of the isomerization reforming reaction and the decomposition reforming reaction depends on a catalyst temperature, and can be altered arbitrarily by controlling an air supply amount to the catalyst (6) via an air amount regulating valve (14) and a fuel supply amount to the catalyst (6) via a fuel injector (8) and thereby controlling the catalyst temperature.

摘要： An internal combustion engine includes a main combustion chamber, an auxiliary combustion chamber, a partition wall that separates the main and auxiliary combustion chambers, a first igniter disposed in the auxiliary combustion chamber, a second igniter disposed in the main combustion chamber, and a controller electrically coupled to the first and second igniters. The auxiliary combustion chamber has a capacity smaller than that of the main combustion chamber. The partition wall includes a communication passage. The controller is adapted to send an auxiliary combustion chamber ignition timing signal to the first igniter and is adapted to send a main combustion chamber ignition timing signal to the second igniter. Further, the controller is adapted to send the auxiliary and main combustion chamber ignition timing signals such that, in response to at least one engine operating condition, ignition in the auxiliary combustion chamber occurs after ignition in the main combustion chamber.
