    Abstract: A stroke detection apparatus performs a stroke detection of 4-cycle engine based on a rotary engine speed when a throttle opening is large. A first crank-pulse time interval between a crank pulse inputted before a top dead center by 30°, and a crank pulse of the top dead center is measured by a pulse-interval calculation unit, and at the same time, a second crank-pulse time interval between a crank pulse inputted after the top dead center by 60° and a crank pulse inputted after the top dead center 90° is measured. An interval difference calculation unit calculates time-interval difference by subtracting the second crank-pulse time interval from the first crank-pulse time interval, for two continuous top dead centers. A stroke detection unit determines whether two top dead centers are a compression top dead center or an exhaust top dead center based on magnitudes of the time-interval differences.

An oil temperature sensor is configured to detect temperature of lubricating oil for the transmission. A controller is configured to control the electric motor. The controller controls the electric motor to operate in a preset first motor duty until a first predetermined time elapses after operation of the electric motor is started when the shift drum is turned from a first predetermined position to a second predetermined position. The controller is also configured to operate the electric motor in a second motor duty calculated based upon oil temperature after the first predetermined time elapses.

    Abstract: The present invention provides an intake air amount control apparatus for an engine and a control method of an intake air amount of an engine, in which, when the atmospheric pressure exceeds a threshold value, a target lift amount of an intake valve is determined based on a target intake air amount and an electronically controlled throttle is controlled to generate a target boost pressure. On the other hand, when the atmospheric pressure does not exceed the threshold value because of a vehicle traveling at a high altitude, the target lift amount of the intake valve is fixed to a maximum lift amount and the opening angle of the electronically controlled throttle is determined in response to the target intake air amount. Consequently, an actual intake air amount is controlled to be brought to the target intake air amount thereby generating negative pressure necessary for exhaust gas recirculation.

    Abstract: Variable valve control method and apparatus for an internal combustion engine provided with a variable valve mechanism that varies an operating characteristic of an intake valve, for controlling a gas amount passing back through the intake valve by variably controlling the operating characteristic. A storage section stores previously a correlation between a value equivalent to an opening area of the intake valve and a valve passing gas amount, corresponding to predetermined effective cylinder capacity. A conversion section converts that value equivalent into the valve passing gas amount by referring to the correlation. A correction section corrects the value equivalent based on a ratio between the converted valve passing gas amount and a requested valve passing gas amount. A calculating section calculates requested effective cylinder capacity (by which the requested valve passing gas amount can be obtained based on the value equivalent to the opening area) based on the valve passing gas amount obtained by referring to the correlation based on the corrected value equivalent to the opening area, and the requested valve passing gas amount. A control section controls the variable valve mechanism according to the requested effective cylinder capacity calculated.
