Intercooler controller of turbo diesel engine

Abstract

Abstract PURPOSE:To improve control accuracy by boring a bypass hole while bringing both upper and lower intake passages of an intercooler into contact with each other, dispensing with a bypass passage, and openly and closely controlling a bypass valve according to temperature and operation conditions. CONSTITUTION:In a diesel engine 2, a compressor 14 of a turbocharger 4 and an intercooler 6 are arranged at the upper and lower sides of an intake passages 12, and a turbine 20 of the tubocharger 4 is arranged at an exhaust passage 18. In this case, a bypass hole 22 is bored while upper and lower intake passages 12-1, 12-2 of the intercooler 6 are brought into contact with each other, and a bypass valve 24 is arranged at the bypass hole 22. The bypass valve 24 is opened and closed via an actuator 26 by a control part 28 based on detection signals from sensors 30-38 which detect temperature and operation conditions of the diesel engine 2. The bypass passage is dispensed and control accuracy is improved accordingly.
