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： A split injection of gasoline produces stratified charge in at least one cylinder. A sensor measures cylinder pressure or knock and generates a sensor signal indicative of combustion event timing of stratified charge. From the sensor signal, a controller determines an actual value of a characteristic parameter representing combustion event timing in the cylinder. The controller modifies at least one of operating variables governing a split injection for the subsequent cycle in such a direction as to decrease a deviation between the actual value of the characteristic parameter and a target value thereof toward zero.

摘要： Before warmup of a fuel cell stack (1) is complete, a cooling water pressure of the fuel cell stack (1) is suppressed lower than the pressure used when the fuel cell system is run in the steady state. In this way, when the system is started from a low temperature state, water in a cathode (2) and anode (3) flows efficiently into the cooling water passage (9), and water clogging is prevented while maintaining a proper water balance in the fuel cell system.

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.
