摘要： PROBLEM TO BE SOLVED: To provide a variable valve controller capable of improving phase variable responsiveness. SOLUTION: A minimum hydraulic oil pressure for controlling a vane rotor 63 is equal to or higher than a minimum hydraulic oil pressure for controlling a piston member 57, and a piston member 51 is hydraulic-controlled to such a level that an intake camshaft 3 is not moved from a lowest lifting position toward a high lifting position or from a highest lifting position toward a low lifting direction. Thus, when the phase of the intake camshaft 3 is made variable, the piston member 57 is always made variable. Therefore, even when the intake camshaft 3 is held in the lowest lifting position or the highest lifting position, by making the piston member 57 variable from the lowest lifting position toward the high lifting direction or from the highest lifting position toward the low lifting direction, the phase control of the intake camshaft 3 is highly accurately performed for a timing pulley 60, and the phase variable responsiveness of the intake camshaft 3 is improved.

摘要： PURPOSE:To improve power and fuel consumption regardless of type of fuel by controlling both an ignition timing responding to the knocking detected output and a supercharged pressure according to an ignition timing map prepared with relation to octane value and supercharged pressure data determined according to the map, respectively. CONSTITUTION:When control for high-octane gasoline is discriminated in an interruption routine, a supercharged pressure is set to a higher value so that a waist gate valve 22 will not be opened until the supercharged pressure reaches the high level. When ignition timing arithmetic operation is performed using a high-octane gasoline ignition timing map and occurrence of knocking is detected from the output of a knocking sensor 12, whether successive occurrence of the knockings has been made or not is discriminated and if precedent knocking is not found, ignition timing is delayed by a certain angle. If successive occurrence of knockings has been made, the octane number is found improper and thereafter ignition control as of regular gasoline is performed. When the control performed when regular gasoline is used is discriminated, the supercharged pressure is set to the lower pressure level and arithmetic operation of ignition timing is executed according to a regular gasoline ignition timing map to provide the optimum output.

摘要： PURPOSE:To prevent deposit from sticking inside an exhaust chamber of a pressure regulation valve and to allow the controller available with lead gasoline by bleeding atmosphere into the exhaust chamber when suction negative pressure is increased due to deceleration or other reasons. CONSTITUTION:When a suction negative pressure inside a suction passage 10, detected by the second sensing port 82, is reduced to a high negative pressure exceeding a certain value because of sudden closing of a throttle valve 12 at deceleration or the like, a vacuum switch 74 senses the high negative pressure and outputs an ON signal to VSV 76. When VSV 76 is thereby opened, atmosphere is directly bled into an exhaust chamber 46 of a pressure regulation valve 22 via the second check valve 78 to scavenge gas therein with the aid of pulsated exhaust gas. On the other hand, when a suction negative pressure inside the suction passage 10, detected by the second sensing port 82, is increased over a vacuum switch setting pressure, VSV 76 is closed to cut off the bleeding of atmosphere from the second check valve 78 into the exhaust chamber 46.

摘要： PURPOSE:To prevent deposit from sticking inside an exhaust chamber of a pressure resulation valve and to allow the controller available with lead gasoline by bleeding atmosphere into the exhaust chamber to scavenge the same when EGR is OFF. CONSTITUTION:When control negative pressure from a pressure regulation valve 22, applied in a diaphragm chamber 32 of an EGR valve 20, yields to a specific force of a compression spring 34 which is disposed inside the diaphragm chamber 32, a vacuum switch 72 is turned ON. Responding to the ON signal, VSV74 is opened. At the opening of VSV74, atmosphere is bled into both an exhaust chamber 46 of the pressure regulation valve 22 and a constant pressure chamber 40 of the EGR valve 20 via respective primary and secondary check valves 76 and 78 with the aid of pulsated exhaust gas to scavenge both the chambers. On the other hand, when EGR is ON, the vacuum switch 72 is kept OFF so that VSV 74 is closed.

摘要： PURPOSE:To obtain the effective removal of the accumulated deposit in a diaphragm chamber by supplying the air by an air-introduction means into the diaphragm chamber for scavenging when a negative pressure regulation value to regulate the negative pressure for leading to an EGR control valve is continuously opened. CONSTITUTION:When a throttle valve 3 is opened to surpass the first negative pressure take-out port 16, a suction negative pressure is regulated in a negative pressure regulation valve 19, and introduced into a diaphragm chamber 14 of an EGR control valve 8 from a pipe 17 to open the valve 8 for exhaust gas returning. Meanwhile, when a throttle valve 3 is opened to surpass the second negative pressure take-out port 31, a diaphragm 20 of the negative pressure regulation valve 19 is moved upward against a spring 23, and a port 24 is closed by a valve element 25. Simultaneously, a negative pressure control valve 37 is opened, and an entrance port 34 of a nonreturn valve 33 is opened to the open air. Consequently, by the pulsation of exhaust gas, the open air is introduced into the first diaphragm chamber 21 for scavenging the same chamber 21.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve timing apparatus which secures detection precision of actual valve timing without excessively increasing a calculation load in accordance with change in engine speed. SOLUTION: When the engine speed is high (determination of YES at S100), actual intake valve phase IV(θ) is calculated based on rotation phase difference between rotation angles of crankshaft and camshaft, detected by using a crank angle signal and a cam angle signal, and actual valve timing is detected therefrom (S110). When the engine speed is low (determination of NO at S100) and the crank angle signal and cam angle signal are unstable, an amount of change in camshaft rotation phase dIV(θ) by the VVT mechanism in accordance with the operation amount of actuator detected by a motor rotation angle signal is calculated successively (S120), and based on an accumulation operation of the amount of change dIV(θ), the actual intake valve phase IV(θ) is calculated, and the actual valve timing is detected (S130).

摘要： PROBLEM TO BE SOLVED: To stop power supply to an actuator so as to maintain a phase, and to change opening and closing timing in a big range. SOLUTION: An ECU executes a program including a step (S110) which interrupts power supply to an electric motor if the phase of an intake valve is in the first domain between a maximum angle of lag and CA(1) (YES at S108). In the case when the phase of the intake valve is in the first domain between the maximum angle of lag and CA(1), a relative rotation speed between an output shaft of an electric motor and a sprocket is decelerated by a reduction ratio R(1), and the phase of the intake valve is changed. When the phase of the intake valve is in a second domain between CA(2) (CA(2) is on a lead angle side than CA(1)) and a maximum angle of lead, the relative rotation speed between the output shaft of the electric motor and the sprocket is decelerated by a reduction ratio R(2) (R(1)>R(2)) and the phase of the intake valve is changed.
