    摘要: An apparatus (11) for controlling the peak pressure in the combustion chamber (46) of a turbo-charged diesel locomotive engine (12). A pressure relief valve (56) is disposed in the compressor discharge downstream of the turbo-charger (18). The relief valve (56) is operable to release a selected amount (58) of the compressed air (24) produced by the compressor section (20) of turbo-charger (18). The actuation of valve (56) may be a function of the pressure of the compressed air (24), and/or a manifold air temperature signal (52) and a fuel injection timing signal (40). An actuator (60) attached to valve (56) is responsive to a valve position signal (62) generated by a controller (38) having the appropriate inputs and programmed logic capability.
