摘要： PROBLEM TO BE SOLVED: To provide a high pressure fuel supplying device of an internal combustion engine, capable of securing good restartability in the high temperature of an engine. SOLUTION: A controller 90 closes a low-pressure fuel passage 70 and also releases a high-pressure fuel passage 80 by opening and closing respective electromagnetic control valves 60, 83 before cranking is started, and high-pressure fuel in a delivery pipe 50 is introduced into a pressurizing chamber 46. When it is judged that vapor is generated in the pressurizing chamber 46 after cranking is started, the controller 90 opens respective electromagnetic control valves 60 to release both fuel passages 70, 80, and fuel is supplied from a feed pump 32 to the delivery pipe 50 through the pressurizing chamber 46 on the basis of the feeding operation of the feed pump 32.

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 realize a detection of deterioration degree other than an injection amount such as an injection shape in a fuel injection valve and to suitably control an engine by reflecting it to a control of an internal combustion engine. SOLUTION: In order to determine a shape-like deterioration in a fuel injection valve, a presumed fuel injection operation amount Qx at a laminated combustion is corrected by a quantitative injection correction amount Qvol determined from a quantitative deterioration degree Dvol in the fuel injection valve and a presumed fuel injection operation amount Qz after correction is determined (S470). A lack degree 'Q-Qz' which the presumed fuel injection operation amount after correction Qz has against an actual fuel injection operation amount Q is determined and a shape-like deterioration degree variation amount ΔDshp is determined by dividing it by the actual fuel injection operation amount Q. A shape-like deterioration degree Dshp, i.e., a deterioration degree other than a fuel injection amount from this shape-like deterioration degree variation amount ΔDshp (S490). Thus, the shape-like deterioration degree Dshp only indicating a deterioration degree other than the fuel injection amount can be determined and a preferable engine control becomes possible.

摘要： PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine which prevents shortage and excess of an internal EGR amount when starting the internal engine from a cooling state. SOLUTION: A valve timing of an air intake valve is timed from the most retardant state by a hydraulic drive of a valve timing variable mechanism 25, and a valve overlapping becomes to increase an internal EGR amount. A hydraulic circuit for driving the valve timing variable mechanism 25 is formed so that oil in the part of the mechanism 25 side is distinguished from the oil in the part of the oil pump 32 side. Therefore, the oil in the mechanism 25 side used as working oil of the valve timing mechanism 25 in the hydraulic circuit can be employed for the one to be low volatile at low temperature compared with the oil of the oil pump 32 side used for lubricating oil of an engine. This process suppresses a response delay in action of the valve timing variable mechanism 25 when starting the engine at the cooling state. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To detect the abnormality of the viscosity of an oil as an medium for feeding the hydraulic pressure based on the operation condition of a variable valve timing mechanism in a valve timing control device of an internal combustion engine with a hydraulic pressure supply means and the variable valve timing mechanism for changing the open/close timing of at least either one of an intake valve or an exhaust valve based on the hydraulic pressure fed from the hydraulic pressure supply means based on a given target value. SOLUTION: The abnormality of the viscosity of the oil is determined based on either the deviation between the motion track of a previously set valve timing and the actual valve timing, the deviation between a target valve timing and the actual valve timing after the variable valve timing mechanism is operated and a prescribed period of time elapses, or the period of time having elapsed after the operation of the variable valve timing mechanism is outputted when the actual valve timing reaches a prescribed value.

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 control device for a cylinder injection type internal combustion engine, capable of suppressing starting failures at restart or the like.
SOLUTION: The valve timing of an intake valve 20 in an engine 1 is made variable, by hydraulically controlling a valve-timing variable mechanism 25. When it is judged that the valve timing variable mechanism 25 does not return to the position of locating the valve timing of intake valve 20 as a most delay angle (reference position) at start of the engine 1, the fuel injection amount during engine start and immediately after finishing the engine start, is corrected to be reduced. Thereby, even if the valve timing variable mechanism 25 does not return to the reference position and an internal EGR amount is excessive by the fuel combustion in such a state as to cause an insufficient oxygen condition, it can be suppressed that an air/fuel ratio becomes excessively rich due to such a situation.

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.
