Abstract: A mask is disclosed for use in painting of a motor vehicle wheel of the type comprising a hub, which is to be painted, and a tyre disposed upon the hub. The mask comprises at least two mask panels 2, each having a concave arcuate inner edge 4. The individual panels can be arranged together around the wheel hub 8 with their inner edges 2 lying adjacent and conforming to the rim of the wheel hub. Together the mask panels 2 therefore form a ring around that rim, covering at least part of the tyre wall and so protecting it from inadvertent application of paint.

Abstract: A throttle control system includes a valve, an electric throttle unit, a control unit, a throttle sensor, a memory device, and a memory execution unit. The throttle control system operates the memory execution unit to allow the memory device to store an opening signal detected by the throttle sensor as a “detected full opening” of the valve, when energization of the electric throttle unit is stopped by the control unit and the valve stops at a “mechanical full opening” by mechanical operation. Thus, it becomes possible to coincide the actual valve opening of the valve and a “control valve opening” which the control unit recognizes. Therefore, it becomes possible to decrease system variation between the electric throttle unit and the control unit. Moreover, a control accuracy of an air intake amount by the throttle control system can be improved.
