摘要： A two-stroke internal combustion engine achieves high performance levels by using an innovatively timed sequence of injecting and igniting fuel and oxidant. The operating cycle of the engine does not utilize a compression process. This permits the injection of fuel and oxidant to be coordinated with the initiation of the combustion process in such a way that the engine achieves high efficiency and provides high torque, while at the same time producing low thermal loading of engine components and low levels of engine noise and vibration.

摘要： A control device for an on-board compression-ignition engine in which partial compression-ignition combustion including spark ignition (SI) combustion performed by combusting a portion of mixture gas inside a cylinder by spark ignition followed by compression ignition (CI) combustion performed by causing the rest of the mixture gas inside the cylinder to self-ignite is executed within at least a part of an operating range of the engine, is provided. The device includes a detector configured to detect a parameter related to noise caused by the combustion inside the cylinder, and a combustion controller configured to control the combustion inside the cylinder during the partial compression-ignition combustion based on a combustion noise index value identified by the detected parameter of the detector and a given reference value defined as an upper limit of the combustion noise index value, the reference value increasing as a vehicle speed increases.

摘要： An internal combustion engine has a cylinder, a cylinder head mounted to the cylinder, a piston disposed in the cylinder, and a fuel injection valve. A combustion chamber is defined by the piston, the cylinder head and the cylinder. The fuel injection valve has a plurality of injection holes that injects fuel directly inside the cylinder from a side of the combustion chamber. The injection holes inject fuel in a spray shape with an overall shape, which is formed by a plurality of sprays being injected from the injection holes. The overall shape expands toward the cylinder head and forms one part of a conical shape that is dented near the piston. Central axes of some of the injection holes are oriented toward a boundary portion near the exhaust valve formed at a crown surface of the piston and an inner wall of the cylinder when fuel is injected.

摘要： In a method of operating an internal combustion engine with direct fuel injection such that, in the engine startup period, a three-way catalytic converter disposed in the engine exhaust system is rapidly heated to a working temperature, in that a fuel quantity which is injected is injected in two separate injection steps with the first fuel volume being injected during the intake stroke and the second fuel volume being injected during the expansion stroke so as to form immediately before the ignition instant a rich stratified charge cloud in the region of the spark plug thereby ensuring reliable ignition of the stratified cloud while, overall, achieving a lean fuel/air mix in the combustion chamber.

摘要： A control system for a compression-ignition engine is provided, which includes the engine, a spark plug, a fuel injection valve, an air-fuel ratio control valve, and a control unit. A geometric compression ratio of the engine is 14:1 or above. The control unit includes a processor configured to execute an air-fuel ratio controlling module for, when the engine being in a given operating state is detected, controlling the air-fuel ratio control valve to bring the air-fuel ratio of the entire mixture gas to a given lean air-fuel ratio that is larger than a stoichiometric air-fuel ratio, and an spark plug controlling module for, after this control, outputting the control signal to the spark plug to perform the ignition at a given ignition timing so that the mixture gas starts combustion by flame propagation and then unburned mixture gas self-ignites. The given ignition timing is stored in a memory.

摘要： A control system for a compression-ignition engine is provided, which includes an engine having a combustion chamber, an injector, a spark plug, a swirl valve provided to an intake passage of the engine, and a controller connected to the injector, the spark plug, and the swirl valve to control them. The controller includes a processor configured to execute a swirl adjusting module to control an opening of the swirl valve so as to make the opening of the swirl valve smaller as an engine speed decreases and output a control signal to the injector to inject the fuel after the control of the swirl valve, and a combustion controlling module to output an ignition instruction to the spark plug so as to ignite at a given ignition timing after the EGR ratio adjustment, so that partial compression-ignition combustion is performed.
