The efficiency of common rail diesel engine is higher and higher, the loss of heat is lower and lower. It means it is difficult to use waste heat of engine for air conditioning. For that reason, engine independent heater for cabin room was required and fuel air heater was developed. Domestic requirenemt of Fuel pre heater is higher, t localization of the heater is required. Test method for fuel pre heater have to be developed because operation condition is severe and climate of domestic region is mild compared with other northern country. This research carried out analysis of exhaust gas of heater prototype and development of low temperature heater start tester. Low temperature start test result through test equipment was clearly visible.
