Abstract: An engine combustion device control system is disclosed, wherein, as a flywheel 10 rotates, a detection sensor 70 detects indexes 20a formed on an inner surface of the flywheel 10 to accurately measure the number of engine revolutions and a piston position. The indexes 20a are formed along a circle concentric with a rotational center of the flywheel at a substantially equal spacing and grouped to fall into different kinds of discrete angular sections, making it possible to accurately estimate the number of engine revolutions and the time at which a piston reaches a top dead point. This removes the need for a separate rotating disk other than the flywheel and enables an electronic control unit of an engine to control the timing of injection and ignition of mixed gas in an accurate manner.

Abstract: The resistance to unseating of at least one tire mounted on a mounting rim and inflated to a predetermined pressure is determined by mounting the tire/rim unit on a vehicle in a steering axle position. The vehicle is set in motion in a straight path and stabilized at a predetermined speed.

If the tire does not unseat, increases in the steering angle are made periodically so that the vehicle travels in progressively tighter circular trajectory arcs until either the tire becomes unseated or the steering wheel reaches its terminal stop.
