摘要： An internal combustion engine is operated on auto-ignition combustion of fuel with low cetane number like gasoline. The engine has at least one cylinder and a reciprocating piston in the cylinder to define a combustion chamber. Combustion event in the cylinder is expressed in terms of two variables. They are main combustion timing (&thgr;50) and a main combustion period (&thgr;20-50). The main combustion timing (&thgr;50) represents a crank position when mass burnt rate is 50 percent. The main combustion period (&thgr;20-50) represents a period from a crank position when mass burnt is 20 percent to a crank position when mass burnt is 50 percent. Controlled parameters governing main combustion are varied to adjust the main combustion timing on an advance side of a retard limit (&thgr;50 max) and to adjust the main combustion period within a range between an upper limit (&thgr;20-50 max) and a lower limit (&thgr;20-50 min).

摘要： An internal combustion engine has a fuel injection system capable of performing a multiple injection wherein a main injection event and a trigger injection event take place in this order in one cycle. With main injection, fuel is widely dispersed within a combustion chamber to create a main mixture for main combustion. With trigger injection, fuel is dispersed locally within the combustion chamber to create an ignitable mixture for auto-ignition. Auto-ignition of the ignitable mixture creates condition under which auto-ignition of the main mixture takes place. Fuel quantity and timing for each of main and trigger injections are varied corresponding to engine speed and load request to cause the main mixture to burn at a target crank angle after TDC of compression stroke.

摘要： A fuel supply system has a fuel injector positioned to directly inject fuel into a combustion chamber, and it is capable of performing a split injection wherein a first fuel injection in each engine cycle precedes a second fuel injection that occurs during compression stroke in the same engine cycle. A spark plug produces a spark to ignite a first air/fuel mixture portion created due to the second fuel injection, initiating a first stage combustion. The first stage combustion raises temperature and pressure high enough to cause auto-ignition of a second air/fuel mixture portion surrounding the first air-fuel mixture portion, initiating a second stage combustion. This control is accomplished by varying at least one of a fuel injection timing of the first fuel injection, a fuel injection timing of the second fuel injection, spark timing, a proportion of fuel quantity of the second fuel injection to the total fuel injected in each engine cycle, and an EGR rate in response to at least one of engine speed and load.

摘要： Fuel cells (20) are superimposed one upon the other in the stacking direction. Each fuel cell (20) comprises an anode gas passage (32) and a cathode gas passage (36). Each passage has a meandering configuration provided with two or more bent portions (511, 512, 521, 522). At least the most downstream bent portion (512, 522) of at least one of the anode gas passage (32) and the cathode gas passage (36) is connected to a through-hole (332, 372) extending through the fuel cell stack (1) in the stacking direction of the fuel cells (20). The through hole (332, 372) averages out the condensed water in the anode gas passages (32 )or the cathode gas passages (36) and prevents flooding from being caused in a specific anode gas or cathode gas passage.

摘要： A self-ignition combustion engine has a control unit that controls the temperature of the intake air such that the operating load range of compression self-ignition combustion is expanded. In operating regions where cooling the intake air results in an intake air temperature that is too low and an inability to conduct self-ignition operation, the temperature of the intake air is raised by directing intake air that has been supercharged by a supercharger to a bypass passage so that it does not pass through an inter-cooler.

摘要： A gasoline engine has an actuating system including an in-cylinder fuel injection system and an ignition system, capable of changing over combustion between spark ignition combustion and compression autoignition combustion, and a controlling system for controlling the combustion changeover. In a transition from one combustion to the other, the actuating system is controlled to perform transient combustion such as stratified charge combustion with fuel injection on the compression stroke, or combustion with fuel injection during a valve shutoff period during which intake and exhaust valves are both closed.

摘要： A system and method for controlling an internal combustion engine employs a split injection to create stratified air/fuel mixture charge. The stratified charge includes an ignitable air/fuel mixture portion around a spark plug within the surrounding lean air/fuel mixture and experiences a two-stage combustion. The first stage is combustion of the ignitable air/fuel mixture portion initiated by a spark produced by the spark plug, providing an additional increase of cylinder pressure. The second stage is auto-ignited combustion of the surrounding lean air/fuel mixture induced by such additional cylinder pressure increase. The system and method also employ generating a combustion event indicative (CEI) parameter related with combustion speed or ignition timing point of auto-ignition of auto-ignited combustion of the surrounding mixture, and determining control parameters of a spark timing controller and a fuel supply controller in response to the CEI parameter.
