Abstract:
A crank angle detector and an ignition timing controller comprises a rotor rotated in association with a crank shaft of an internal combustion engine and having detection portions to be detected at equivalent angle intervals in the outer circumference; and a pickup arranged in the vicinity of the outer circumference of the rotor, for generating a pulse signal when the detection portions each pass; wherein one detection portion located immediately before the crank angle corresponding to the upper dead point of a piston of the internal combustion engine, of the detection portions is set to detect a reference angle of the crank angle.
Abstract:
A control apparatus for an internal combustion engine, includes: a fuel injection unit; an ignition unit; a crank angle detection unit; a fuel pump; a booster unit; an ignition discharge unit; and a control unit that controls the fuel injection unit, the ignition unit, and the fuel pump, that ascertains ignition timings based on crank signals output from the crank angle detection unit, and that performs a startup control sequence that is made up of fuel injection processing, voltage boosting processing, ignition processing, and fuel supply processing.
Abstract:
A rotor is provided such that the rotor rotates with a crank shaft of an engine. A plurality of detection sections are formed on a rotor periphery at equal angle intervals. A particular detection section is used for detection of a reference crank angle. A pickup is provided near the rotor periphery. A crank angle detecting apparatus receives pulse signals from the pickup, and sequentially detects a detection section time. The detection section time is a time interval from the front end to the rear end of the detection section. The crank angle detecting apparatus also sequentially detects a time between each two adjacent detection sections (detection section distance time), which is a time from the rear end of one detection section to the front end of the next detection section. A reference angle detection signal, which indicates detection of the detection section dedicated for the reference angle, is generated when at least two ratio conditions are met. These ratio conditions are decided based on the detection section time and the detection section distance time.

Abstract:
The present invention provides an engine stoppage notification apparatus with which, due to its compatibility with and good correspondence to the intention of a driver to start off a vehicle and to stop and idle the vehicle, it is possible to anticipate the possibility of enhancement of product quality along with alleviation of the burden upon the driver. This engine stoppage notification apparatus notifies the driver that the engine is about to stop when the engine has satisfied certain predetermined stoppage permission conditions, and includes a notification device which, from when the stoppage permission conditions are satisfied until the engine stops, issues a notification of the engine stoppage.
