摘要： An automobile engine (E) capable of changing over the operating area thereof between an operating area with all the cylinders being in action and one with a certain number of cylinders being at rest by stopping the operation of valve operation mechanisms for suction and exhaust in selected cylinders out of a plurality of cylinders, in particular, the engine comprising an engine revolution sensor (12), a boost pressure sensor (10), ignition driving devices (23, 24, 25), and a control device (15) for controlling a mechanism for stopping cylinders and the ignition driving devices, wherein an operating area with certain number of cylinders being at rest is determined from information on engine revolutions Ne and boost pressure Pb, and wherein a torque fluctuation of the engine occurring when the engine operating area is switched from an operating area with all the cylinders being in action to an operation area with a certain number of cylinders being at rest, and vice versa is offset by the retard amount processing of ignition timing or by idle-up so as to prevent the generation of torque shocks resulting from extraordinary change in output occurring when such switching is carried out to thereby prevent stall or improve drivability.

摘要： AN APPARATUS FOR CONTROLLING AN IGNITION OF A CYLINDER-INJECTION GASOLINE ENGINE (1) INCLUDES AN ELECTRONIC CONTROL UNIT (ECU) FOR CONTROLLING THE OPERATION OF AN IGNITION COIL. THE ECU ADVANCES THE IGNITION TIMING IN ACCORDANCE WITH THE THROTTLE OPENING (qTH) IN CONSIDERATION OF A DELAY IN INCREASE OF THE WALL TEMPERATURE (TCW) OF A COMBUSTION CHAMBER (5) WHEN THE ACCELERATION OF A VEHICLE IS DETECTED BY THE CHANGE OF THE THROTTLE OPENING (qTH). IN ORDER TO PREVENT KNOCKING OF THE ENGINE (1) ATTRIBUTABLE TO THE INCREASE OF THE WALL TEMPERATURE (TCW), THE ECU GRADUALLY DECREASES AN ADVANCE ANGLE FOR THE IGNITION TIMING TO 0 WITH THE PASSAGE OF CONTROL TIME. WHEN THE ENGINE (1) IS REACCELERATED DURING THE ADVANCE ANGLE CORRECTION, THE ECU NEWLY SETS AN ADVANCE ANGLE FOR THE IGNITION TIMING AND A CONTROL TIME, CORRESPONDING TO THE INCREASE OF THE WALL TEMPERATURE (TCW).

摘要： PURPOSE:To execute a safe operation without discharging battery excessively by mounting a control means for controlling switching operation of a series- parallel switching means so as to forbidden electric supply to an electric heating catalyst and charge the battery. CONSTITUTION:An electric heating catalyst 3 is mounted in an exhaust pipe 2 of an automobile engine. Temperature of the electric heating catalyst 3 is detected by a sensor 8. When the temperature of the catalyst 3 is high, a controller 7 switches a series-parallel switching relay 6 to a parallel mode and connects batteries B1, B2 in parallel and the batteries are discharged by a generator. When the temperature of the catalyst 3 is low and discharging capacity of the batteries B1, B2 is larger than predetermined value, the series switching relay 6 is switched to a series mode and the batteries B1, B2 are connected in series and electricity is supplied from the batteries B1, B2 to the electric heating catalyst 3. If even one of the discharging capacity of the batteries B. and B. comes to less than the predetermined value, the batteries B1 and B2 are discharged by connecting them in parallel and discharging to the electric heating catalyst 3 is forbidden. Thus, a safe operation can be secured.

摘要： PROBLEM TO BE SOLVED: To improve an output and fuel cost performance while preventing knocking by timing-correcting an ignition time for a specified period immediately after an acceleration driving start corresponding to the delay of a wall temperature increase in a combustion chamber when an internal combustion engine is changed to acceleration running. SOLUTION: Determination is made as to whether a running condition is in an acceleration region or not, and if YES, a time factor Kt is calculated with a function (f) based on the current open degree of a throttle and a timer (t) (the passage of control time) (S47), and a timing control time tx is calculated by using a function (h) based on the time factor Kt (S49). Then, a target average effective pressure Pe is calculated by an expression (S51), a basic ignition time is retrieved from a basic ignition time map based on the target average effective pressure Pe and an engine revolution number (S53), and ignition is performed by driving an ignition coil and outputting a high voltage to a spark plug (S55). After the passage of control time, when the value of the timer (t) exceeds the timing control time tx and determination is YES (S59), an acceleration timing control subroutine is finished.

摘要： PURPOSE:To assemble an assistant unit which is driven by using power of an engine to the engine. CONSTITUTION:A cam shaft l provided with a pump cam 2 on a right side is installed into a cylinder head of an engine. A cam shaft 1 is so rotated and positioned that a base circular space 2a of the pump cam 2 is located on an upper side. A passive pin 7 of an oil pump 6 is abutted against the base circle space 2a of the pump cam 2, while an oil pump 6 is attached to the engine. The oil pump 6 can be assembled without resisting elastic force of a coil spring 8 which pressurizes the passive pin 7.
