摘要： PROBLEM TO BE SOLVED: To decide whether or not an oxygen concentration sensor is abnormal during driving by confirming that an output signal of the oxygen concentration output sensor does not show rich and lean reversals for air-fuel ratio in an air-fuel ratio feedback control drive state. SOLUTION: A CPU 6 determines a fuel injection time with the use of a drive parameter and the number of revolution of an engine. Fuel is injected into an engine 2 during only the fuel injection time. Oxygen concentration is detected by an oxygen concentration sensor 16 from a combustion exhaust gas. By repeating the process, an air-fuel ratio of a supplied mixed gas is fed back to control a theoretical air-fuel ratio. In a fail-safe process, the CPU 6 first decide whether or not a drive state of the engine 2 is in an air-fuel ratio feedback control area and then decides whether or not the drive state is in a rich drive area. When an output level of the oxygen concentration sensor 16 indicates a lean air-fuel ratio, it is decided whether or not a counted value of an anomaly decision counter is larger than a predetermined value, thereby deciding the oxygen concentration sensor 16 as abnormal.

摘要： PROBLEM TO BE SOLVED: To provide a speed change control device capable of both shortening the shift time and reducing the shift shock by controlling a clutch hydraulic pressure during a gear shift operation.
SOLUTION: A first clutch CL1 connects and disconnects a rotational driving force to a main shaft 16. A second clutch CL2 connects and disconnects the rotational driving force to a second main shaft 15. A transmission TM switches the connection/disconnection states of two clutches to enable shifting between adjoining transmission gear stages. The speed change control device includes a linear solenoid valve 28 for supplying clutch hydraulic pressure, a shift valve 25 for switching a hydraulic supply destination between both the clutches, and a control unit 100 for controlling both the valves. When a speed change command is output while a predetermined transmission gear state is selected, and the maximum hydraulic pressure Pa is supplied to one side of both the clutches, the control unit 100 changes over the hydraulic pressure supply destination to the other side of the clutches, and supplies the maximum hydraulic pressure P3 only for a predetermined time ta. After the predetermined time ta elapses, a second hydraulic pressure P2 is supplied only for a second predetermined time tb.

摘要： PROBLEM TO BE SOLVED: To detect opening/closing of an oil pressure switch for neutral detection by a detection device, and to detect disconnection of a wiring connected between the detection device and the switch. SOLUTION: Since connection is made by two pieces of wirings 31, 32 between a second contact 18 and an ECU 40, even if one piece of wirings is disconnected, opening/closing of the oil pressure switch 16 for neutral detection can be detected by the rest of one of them. Since different voltages are applied through respective resistive voltage divider circuits 41, 42 to respective wirings 31, 32, the occurrence of disconnection can be detected by utilizing the difference between the voltage detected by the ECU 40 at opening of the oil pressure switch 16 for neutral detection when one wiring is disconnected and the voltage when the one wiring is not disconnected.

摘要： PROBLEM TO BE SOLVED: To detect the cable breakage of a knock sensor even in an area where the rotational speed of an engine is low.
SOLUTION: The knock sensor 8 is secured to a multi-cylinder engine. A knock signal output from the knock sensor 8 is detected as a noise level in a noise gate period set for each cylinder. The maximum value of the noise levels for cylinders in one cycle is detected. The maximum value of the noise levels is compared with a failure determination value. When the maximum value of the noise levels is smaller than the failure determination value, the sensor is determined to be failed. A knock gate period is a period started from a top dead center of compression. The noise gate period is set in a period different from the knock gate period.

摘要： PROBLEM TO BE SOLVED: To provide a stroke determination device of a four-cycle engine for performing correct stroke determination by using intake pressure as a parameter.
SOLUTION: Combined intake pressure PB of intake ports of first to third cylinders is detected. A form of combined intake pressure waveform in an predetermined crankshaft phase period out of combined intake pressure waveforms based on the detection values of the combined intake pressure Pb is recognized as a Pb pattern of "increase" or "upward peak" to perform stroke determination. The Pb pattern is recognized by recording increase/decrease patterns of intake pressure values measured in the predetermined crankshaft phase period and then being collated with a data map stored in an ECU. Or, the Pb pattern is recognized by collation with a condition expression expressing the "increase" or "upward peak". In the latter case, intake pressure fluctuation by mixing of noise or the like in a Pb sensor is ignored to improve noise toughness of the stroke determination device.

摘要： PROBLEM TO BE SOLVED: To accurately detect a substituted atmospheric pressure in the case of compensating fuel supply by using the atmospheric pressure value substituted with the negative pressure of an air intake pipe. SOLUTION: A plurality of differences between an estimated atmospheric pressure and a calculated, substituted atmospheric pressure are previously set in a region discriminating part 33 in the form of functions of the revolution of engine and the opening of a throttle, and are stored together with a plurality of regions defined by the above differences. By the engine revolution and throttle opening, it is discriminated in which region the engine condition is present, and the offset corresponding to the region is outputted. A calculation part 35 calculates the base value derived from the negative pressure PB and the offset. If the calculated base value is in a fixed relation with the substituted atmospheric pressure determined last time, the latter is renewed with the former. Since the offset values are determined and atmospheric pressure is calculated every region discriminated according to the engine condition, an accurate fuel compensation can be performed in response to the engine condition.

摘要： PROBLEM TO BE SOLVED: To provide a reverse rotation preventive device for a motorcycle engine capable of restarting the engine without temporarily stopping the motorcycle even in case temporary locking of the rear wheel has actuated a reverse rotation preventing function.SOLUTION: The reverse rotation preventive device for motorcycle engine includes a crank pulser rotor 50 furnished with a plurality of reluctors 52 installed at a constant spacing except a tooth missing part H in one place and rotating synchronously with the crank shaft 45 of the engine 8, and a first pulse generator PC1 and a second pulse generator PC2 to emit pulse signals corresponding to the spacing of the reluctors 52. A reverse rotation preventing means 302 in the ECU 30 prohibits ignition of an ignition plug 35a by actuating the reverse rotation preventing function when the interval between pulses of the pulse signals exceeds prescribed time T. If the crank shaft 45 is sensed rotating in the normal direction after ignition was prohibited owing to actuation of the reverse rotation preventing function, the reverse rotation preventing means 302 releases the prohibition of ignition. If the ignition prohibited condition is established after preparation of ignition is made, the primary current in an ignition coil is shut off with a prescribed gradient.
