摘要： A cylinder head gasket includes a pair of first and second outer plates 2, 3 and an inner plate 4 disposed therebetween. The inner plate 4 is formed with containment openings H1 to H10 at given positions therein for receiving sensors S1 to S10. The both outer plates 2, 3 are formed with projections P1 to P10 which project toward the sensor, thus allowing an urging force from a cylinder head or cylinder block to be transmitted to the sensors S1 to S10 through the projections P1 to P10. There can be provided a cylinder head gasket having a sealability comparable to that of a cylinder head gasket not internally housing a sensor while reducing a cost required for parts other than the sensor to be reduced in comparison to the prior art.

摘要： PROBLEM TO BE SOLVED: To decrease the amount of air-polluting substances emitted into atmosphere from a hybrid engine. SOLUTION: A purification unit having the following configuration is mounted on a hybrid engine provided with an internal combustion engine and an electric motor. Namely, the purification unit is provided with: a purification catalyst that purifies air pollutants contained in exhaust emissions; a first exhaust passageway that allows an inflow of the exhaust emissions from one side of the purification catalyst; a second exhaust passageway that allows an inflow of the exhaust emissions from the other side of the purification catalyst; an exhaust passageway selector mechanism that selects either the first exhaust passageway or the second exhaust passageway; and a bypass passageway through which the exhaust emissions bypass the purification catalyst when the exhaust passageway is selected. When the purification unit selects the exhaust passageway, operating conditions of the internal combustion engine are varied so as to decrease the amount of air-polluting substances emitted. This suppresses the amount of air-polluting substances that are not purified by the purification catalyst and that are discharged directly into the atmosphere together with the exhaust emissions through the bypass passageway when the exhaust passageway is selected.

摘要： PROBLEM TO BE SOLVED: To prevent combustion from being unstable since the degree of overlap is excessive during idle operation or low load operation and to prevent occurrence of engine stall in such a case that a variable valve timing mechanism falls in trouble so as to be inoperative. SOLUTION: An ECU 70 controls the drive of VVTs 29L, 29R, and determines whether or not the phase angles θ01, θ02, of actual valve timings of the VVTs 29L, 29R fall in a phase angle range based upon desired valve timing angles θT1, θT2 calculated from an engine rotational speed NE, a water cooling temperature THW and the like, and whether or not such a condition is successively determined by a number of repetitions greater than 5. If it is determined by a number of repetitions greater than 5 that the phase angles are out of the phase angle range, the ECU 70 determines that the VVTs 29L, 29R are erroneously operated, and forces the desired valve timing of the VVTs 29L, 29R which are not erroneously operated, to be fixed to a valve timing which has the minimum degree of overlap.

摘要： PURPOSE: To prevent any engine starting failure due to fuel spitting out of a combustion chamber in regard to such an engine as having no sufficient passage capacity ranging from the combustion chamber up to a throttle valve. CONSTITUTION: Each separated throttle valve 19 is installed in each branch path 12c of an inlet manifold 12. In order to forcibly open each valve 19 in time of engine stoppage, it is provided with an actuator 26 which displaces a diaphragm 27 on the basis of negative pressure, thereby displacing a pin 30. A negative pressure chamber 28 of this actuator 26 is interconnected to the branch path 12c at the downstream side of each valve 19 through a pipe 32. Then a throttle 33 delaying any induction of the negative pressure to the negative pressure chamber 28 is installed in this pipe 32. Accordingly, at the time of engine stoppage when the negative pressure becomes uninduced to this chamber 28, the pin 30 is displaced by the diaphragm 27, whereby each throttle valve 19 is forcibly opened. At the time of engine starting when the negative pressure is started to be taken into the chamber 28, the induction of the negative pressure is delayed by the throttle 33, so a span of timing when each valve 19 is released from the forcible opening is delayed to some extent.

摘要： PURPOSE:To prevent generation of an extreme scattering of sensor temperature when contents stored in a memory keeping a learned value of a target resistance is damaged in a heater control device which varies and controls a heater supply power so that a resistance of the heater which is installed at an oxygen concentration detection sensor becomes a target resistance. CONSTITUTION:When it is detected that contents stored in a memory 15 are damaged by a detection means 17, a heater control means 14 is controlled so that a heater supply power is constant by a power fixing means 18. A calculation means 19 calculates an annealing value of a heater resistance while this heater supply power is maintained to be constant. A control means 20 allows the heater control means 14 to be continued to a heater fixed resistance control and at the same time a value based on the annealing treatment value to be used as an initial value of the target resistance at that time.

摘要： PURPOSE:To secure a proper engine controlled variable at all times by adding a difference with the moderating theoretical value of a theoretical steady intake flow rate, to the moderating measured value of an intake flow rate, and thereby finding the final intake flow rate. CONSTITUTION:An actual intake flow measured value being measured by an intake flow measuring means M7 is moderated so as to vary it gradually, thereby operating the moderating measured value with a moderating measured value operational means M8. In addition, with operating of a throttle valve M3 and engine speed of an internal combustion engine M4 as parameters, a theoretical steady intake flow rate is operated by a steady intake flow operational means M9, and when a preset relationship is set up, the theoretical steady flow rate is moderated so as to be gradually varied, thereby operating the moderating theoretical value with a moderating theoretical value operational means M10. Then, a difference between the theoretical steady intake rate and the moderating theoretical value is added to the moderating measured value at a final intake flow operational means M11, operating the final intake flow rate, and on the basis of the calculated intake flow rate, an engine controlled variable is operated by an engine controlled variable operational means M12.

摘要： PURPOSE:To restrain an air-fuel ratio from shifting to the lean side as well as to abate an amount of harmful ingredient discharge in exhaust gases by compensating an air-fuel ratio feedback control constant to the overrich side at a time when a down-stream side air-fuel ratio detecting means is in a nonactivity. CONSTITUTION:Respective means M3, M4 detecting an air-fuel ratio each are set up in both upper and lower parts of catalytic converter rhodium M2 set up in an exhaust passage of an internal combustion engine M1. When a fact that a driving state of this engine M1 is a specified state is judged by a means M5, an air-fuel ratio feedback control constant is calculated by a means 6 on the basis of the detected result of the means M4. Likewise, according to the calculated constant, an air-fuel ratio controlled variable is calculated by a means M7 on the basis of the detected result of the means M3. In addition, an air-fuel ratio is adjusted by a means M8 according to this calculated controlled variable. In this case, when it is so judged that the means M4 is in a nonactivity by the means M5, the control constant being used at the means M7 is compensated to the overrich side by a means M9.

摘要： PURPOSE:To prevent an internal combustion engine from misfiring by compensating a timing delay value being controlled by an ignition timing delay control means on the basis of a driving state detected by a pre-decelerated driving state detecting means. CONSTITUTION:A driving state of an internal combustion engine is detected by a pre-decelerated driving state detecting means M5 just before being so judged that the engine has shifted to a decelerated state by a deceleration judging means M1 judging of whether a throttle valve has shifted to its decelerated state coming to full-close or not or at time of the judgement. There is provided with a timing delay control value compensating means M6 which compensates a timing delay control value being controlled by an ignition timing delay control means M4 delaying optimum ignition timing set by an ignition timing control means M3 as much as the specified timing delay control value on the basis of the driving state before deceleration detected by the pre- decelerated driving state detecting means M5.
