    摘要: A reverse rotation control apparatus for a two-cycle engine of a motor vehicle which can be implemented inexpensively while preventing exhaust gas composition and ignition performance from degradation. The apparatus includes a variety of sensors for generating a variety of information signals corresponding to engine operating states, and an ignition control unit (10A) for generating an ignition signal (P) for the engine (1) on the basis of the variety of information. The sensors include at least a rotation sensor (6) for generating a rotation signal (SG) and a reverse rotation switch (23) for generating a reverse rotation command signal (RW). The ignition control unit (10A) includes an ignition timing retard control means for causing an ignition timing of the engine (1) to retard beyond a top dead center (TDC) upon inputting of the reverse rotation command signal (RW), an engine rotation number decision means for deciding whether or not a rotation number (Re) of the engine (1) is lowered to a predetermined rotation number (ReW) suited for the reverse rotation control, and an excessively advanced ignition signal generating means for outputting only once an ignition signal (P) advanced excessively relative to a normal advanced ignition timing when the engine rotation number (Re) is lowered to the predetermined rotation number (ReW) suited for the reverse rotation control.

    摘要: A rotational direction change-over control method capable of reversing a rotational direction of an internal combustion engine without discharging unburnt gas. When a reverse command is generated, feed of fuel to the engine is interrupted to reduce a rotational speed of the engine to a set level. An ignition position of the engine is advanced to an excessively advanced position during a reduction in rotational speed to the set level. When the rotational speed is reduced to the set level, feed of fuel is restarted to reverse a rotational speed of the engine. When judgment that the rotational speed is successfully reversed is made, the ignition position is transferred to a position near a top dead center, to thereby maintain rotation of the engine in a direction reversed.

    摘要: Methods and systems are provided for diagnostics of a wastegate valve during vehicle-off conditions. In one example, the engine may be reverse rotated, unfueled, and air flow via the intake manifold may be estimated and compared to a baseline air flow. A stuck open wastegate valve may be indicated based on the comparison between the intake air flow and the baseline air flow.
