Study of Piston Temperature Measurement System used RF-MEMS
It is extremely important to save energy for prevention of global warming. New generation automotive engine ismade up by high compression ratio and low friction by small engine for better fuel consumption. Howeverwith increasing higher compression increasing the piston's temperature exceeds a melting point of thealuminum and a piston is damaged. The measurement of good piston temperature of the precision is very
important for higher compression piston and good fuel consumption. In this paper we made themeasurement of good piston temperature of the precision by RF-MEMS systems.
