Engine visualization is the most important process to develop the new engine. But this step has a major difficulty that is almost impossible to access the engine on running. Therefore, little indication from the experimental and analytical results has been so far. This work has conducted the important issue of developing a quartz liner. And it has given us good qualitative and quantitative results of temperature and stress fields in the quartz cylinder by considering forced convection of outside quartz liner, thickness of the quartz liner and preheating effect to operate quartz engine safely.
