摘要： PROBLEM TO BE SOLVED: To prevent accidental fire at the time of stratified combustion by providing an ignition plug so as to be situated within a cavity on a top face of a piston, providing a fuel injection valve injecting fuel into the cavity and providing a projection part on a part around the cavity so as not to prevent air flow from directly passing an ignition part. SOLUTION: A fuel injection valve 7 is arranged on an intake port 1 side and is constituted so that fuel may be injected in a comparatively thin and flat fan shape. A fuel injection is performed at intake stroke in a uniform combustion area in which a high engine output is required and is performed at the latter half of compression stroke in a stratified combustion area. In a piston 5, a recessed cavity 8 is formed on the top face and an ignition plug 6 is disposed so as to be situated at this cavity 8. In this internal combustion engine, projection parts 9a, 9b for preventing air flow flowing into the cavity 8 from directly passing an ignition part at the end of compression stroke are formed on a part around the cavity 8 of the top face of the piston 5 and accidental fire at the time of stratified combustion is prevented.

摘要： PROBLEM TO BE SOLVED: To avoid a pumping failure of a high pressure pump in an engine start. SOLUTION: Before timing t2 when a crank angle is determined in the start of the cylinder injection type internal combustion engine, an electronic control unit ECU controls duty of energization to a spill valve of the high pressure pump by a cycle comprising very short periods. By the control, the spill valve is opened and closed at minute intervals and a pressure of fuel is raised. After the crank angle is determined, closing start timings of the spill valve are calculated for every predetermined set timings (timings t1 and t5), and the pressure of the fuel is raised by closing the spill valve at the calculated closing start timings (timings t7). After determining the crank angle, the former fuel pressure control is stopped and the spill valve is opened, and switching timing for switching to the latter fuel pressure control is set, for example at timing t4, within a period from right after a start of a delivery stroke of the high pressure pump to the set timing (the timing t5).

摘要： PROBLEM TO BE SOLVED: To provide a start controller for an internal combustion engine capable of properly controlling fuel injection even in a start wherein a fuel pressure to be raised is not stable.
SOLUTION: Pressure of fuel of a fuel tank 10 is raised at a high pressure fuel pump 20 and the fuel is supplied to a delivery pipe 30. The fuel stored in the delivery pipe 30 is suitably injected and supplied to each cylinder of the internal combustion engine 1 via an injector 40. A fuel pressure inside the delivery pipe 30 is measured by a fuel pressure sensor 60, and cooling water temperature of the internal combustion engine 1 is measured by a water temperature sensor 60. Calculation of a fuel injection quantity carried out on the basis of the measured fuel pressure and cooling water temperature is interlocked with fuel injection timing, and measurement of the fuel pressure is carried out each time the calculation of the fuel injection quantity is carried out.

摘要： PROBLEM TO BE SOLVED: To provide a control device capable of suppressing unstableness of the fuel combusting condition in the combustion chamber of an internal combustion engine when exhaust gas exists in the chamber at the time of fuel combustion so as to suppress generation of black smokes. SOLUTION: When the temperature of the combustion chamber 3 is low, the fuel injected into the combustion chamber 3 will not easily atomize and remain in liquid state, and owing to burning sticking of the liquid fuel by the heat of combustion, it is likely that black smokes are generated in the exhaust gas. When the presumed temperature T of the combustion chamber 3 becomes below the value (specified value a2) at which black smokes will be generated, the valve timing of an intake valve 20 is advanced, and the amount of the exhaust gas existing in the chamber 3 at the time of fuel combustion is adjusted incrementally. With this exhaust gas, the temperature of the chamber is heightened to promote atomization of the liquid fuel, and also the combustive temperature is lowered to lead to suppression of the generation of black smokes. The suppression of black smokes as in the described manner is executed only when really necessary such that the presumed temperature T sinks below the specified value a2.

摘要： PROBLEM TO BE SOLVED: To provide a combustion controller for a cylinder injection type internal combustion engine capable of forming an air-fuel mixture of a proper fuel concentration regardless of fuel properties in stratified charge combustion to suppress deterioration of a combustion state. SOLUTION: In this combustion controller, an electronic controller 40 changes over a combustion mode of the engine 10 between the stratified charge combustion and uniform combustion on the basis of an engine load and an engine speed. The electronic controller 40 compares a knock learning value with a reference knock learning value α to detect whether fuel is heavy fuel or light fuel. In the stratified charge combustion, the electronic controller 40 controls such that an interval between injection timing and ignition timing is long, to secure a time for vaporization of the fuel, in the case of the heavy fuel. In the case of the light fuel, the electronic controller 40 controls such that the interval between the injection timing and the ignition timing is short. Thereby, dispersion of the fuel is suppressed.

摘要： PROBLEM TO BE SOLVED: To prevent a sense of incongruity of a driver due to extension of starting time while shortening pressure rising time of fuel in starting.
SOLUTION: An electronic control unit ECU raises pressure of the fuel by a low pressure pump in starting of the cylinder injection type internal combustion engine (steps 100 and 110). When a fuel pressure P inside a delivery pipe reaches a first predetermined value P1 after starting the pressure raising, a high pressure pump raises the fuel pressure (steps 120 and 140). When the fuel pressure P reaches a second predetermined value P2 after starting the pressure raising by the high pressure pump, fuel injection from a fuel injection valve is allowed (steps 160-180). The ECU evaluates progress of the pressure raising by each pump (steps 120, 130, 150 and 160), and when it is evaluated that the pressure raising is slow, injection timing of the fuel from the fuel injection valve is advanced (steps 140 and 190).

摘要： PROBLEM TO BE SOLVED: To prevent a combustion state from deteriorating due to inflow of liquid stored in a surge tank in large quantity into a combustion chamber in a variable intake device of an internal combustion engine. SOLUTION: In the variable intake device, a surge tank 23 has an intake air introduction opening 28 and a blow-by gas introduction opening 29. An inner wall and a dividing wall 27 of a surge tank 23 define an intake air passage inside the surge tank 23. The intake air passage is divided into a main pipe line 21 constantly communicated with the surge tank 23, and an auxiliary pipe line 22 selectively communicated with or blocked off from the surge tank 23 according to an operation of an on-off valve 33 which is driven to close based on a condition satisfied at prescribed intervals. On the other hand, a liquid reservoir part 32 is formed at a bottom of the dividing wall 27. The liquid reservoir part 32 stores engine oil contained in blow-by gas and an intake air introduced from the two introduction openings and separated inside the surge tank 23. The engine oil stored in the liquid reservoir part 32 is introduced into the main pipe line 21 via a liquid return aperture 31. An intake air inlet 22a of the auxiliary pipe line 22 is disposed above the liquid reservoir part 32 in a vertical direction. COPYRIGHT: (C)2010,JPO&INPIT
