【Abstract】 A new fault diagnosis method for charger - air cooler without disassembling the engine has been introduced. Feature parameters reflecting fault status of charger -air cooler has been obtained by measuring the resistance of charger-air cooler to charger-air, the inlet and outlet temperature of charger-air and cooling water. The status and typical faults in charger-air cooler was successfully diagnosed.更多还原
