Abstract: A broach for internal broaching is formed on its pull end and/or follower end with a tapered surface machined with high accuracy. A pull head and/or a retrieving head of a broaching machine, which drivingly grip the pull end and the follower end the broach, is formed with a tapered inner surface complementary to the tapered surface of the broach. The pull head and the retrieving head grip the broach while pressing and clamping their tapered inner surface against the tapered surface, and these heads and the broach are firmly connected together. Clearances or gaps between the heads and the broach are thus eliminated, concentricity between the heads and the broach is significantly improved, and broaching can be performed with high accuracy.

Abstract: Effects caused by unevenness among drive power sources and transmission torque changing apparatus and aging effects in a vehicle transmission are controlled without using sensors. A power train control unit releases engine torque through an assist clutch to release at least a part of gear train transmission torque to shift a meshing clutch toward a release position. During the gear release, a load is applied in a direction in which the meshing clutch is shifted toward the release position, before the transmission torque of the gear train is completely released, and the meshing clutch is shifted to the release position when at least a part of the transmission torque of the gear trains is released.

Abstract: In a configuration where it is judged whether or not a misfire occurred, based on the comparison between diagnosis data indicating a variation of an engine rotation speed and a threshold based on engine operating conditions, the misfire judgment is canceled based on a result of the comparison between data indicating an average correlation between the diagnosis data and the threshold, and a threshold for cancellation judgment.

When the detected battery voltage is smaller than a predetermined reference value, performance of the engine is degraded, and when the detected battery voltage is smaller than a reference value, that is smaller than the predetermined value, the engine is stopped.

Abstract: A fuel injection quantity control system for starting a two-cycle engine. The control system calculates an initial fuel injection quantity by correcting a basic fuel injection quantity according to a subtrahend to be applied to a time factor which is determined depending on a cranking time. The time factor is differently set for a first engine start operation and second or later engine start operation, thereby improving restart of the engine.

Abstract: An engine start control system wherein the engine is restarted after the engine is scavenged without supplying of fuel from a fuel injection valve by cranking only when the engine almost stops as well as when a driver wants to scavenge. The driver's intention to scavenge a combustion chamber of the engine is detected by a control switch which the driver can turn on or off or an opening degree of a throttle valve in an intake passage when the opening degree is equal to or exceeds a predetermined value.
