摘要： PROBLEM TO BE SOLVED: To provide a piston for an engine, reducing slap noise caused by the enlargement of a clearance to a bore at low temperatures.
SOLUTION: The piston 1 includes a latent heat storage material 13 disposed at a skirt 4, and a mass member 14 acting to accelerate the phase change of the latent heat storage material 13 in a supercooled state at the time of engine start by acting according to piston motion. The mass member 14 acting according to piston motion acts to accelerate the phase change of the latent heat storage material 13 in the supercooled state at the time of engine start by applying impact on the latent heat storage material 13 through a soft member 12, concretely speaking. At that time, the latent heat storage material 13 releases stored latent heat. Temperature of the skirt 4 is raised thereby, and the skirt 4 is expanded through heat. Consequently, the clearance to the bore is quickly reduced.

摘要： PROBLEM TO BE SOLVED: To provide an engine cover sufficiently absorbing shocks even if a space between a bonnet hood and the engine cover is relatively narrow, and surely protect pedestrians.
SOLUTION: The engine cover 10 comprises a cover member 5 covering at least a part of an engine 1, and a support means 7 supporting the cover member 5 to have a predetermined space between the support means and a surface of the engine 1. In the engine cover 10 provided in the invention, the support means 7 has a shock sensing member sensing shocks, and can move so that the cover member 5 reaches approximately the surface of the engine when the shock sensing member has sensed the shocks. Even if the space between the bonnet hood 2 and the cover member 5 of the engine cover 10 is relatively narrow at normal times, the bonnet hood 2 can sufficiently deform when the shocks occurs. Therefore, the shocks are sufficiently absorbed to surely protect the pedestrians.
