The Basic Study of Safety Evaluation for Cylinder wall of Small output 2 Cycle Engine
The small output two-cycle engine is used though the main current of the engine is 4-cycles.It will come to often use the raw material of two-cycle engine with the recycle material. A crack, an empty hole, and the inclusion that cannot do visible at the casting process might mix chiefly, this is not avoided as a recycle raw material. This is exposed under a severe environment in the high temperature and the high pressure in the cylinder, the crack is caused against the cylinder wall, the stress concentration is caused of the destruction while the aged deterioration and the crack progresses. In addition, the cylinder wall deforms heat in the state of a high temperature and high-pressure power.The stress occurs on the crack tip that an empty hole and the inclusion besides the crack are against mixing or the cylinder wall. It is forecast for the stress to concentrate on crack vicinity, for the crack progress to happen. The thermal deformation of a cylinder in two-cycle engine is thought that it is necessary and indispensable to investigate these from the viewpoint of the dynamic mechanics. This research experimented the cylinder deformation under the high temperature, tried to calculate a simulation, and experimented the relation between the temperature and the pressure in the cylinder and measured the deformation of an engine.
