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 timin...
[ We claim as our invention:] [1.]1. A method of protecting a turbo-charged diesel locomotive engine from excessively high combustion chamber pressure, the method comprising the steps of:determining an allowable combustion chamber pressure for the turbo-charged diesel engine;determining a first pressure rise in the combustion chamber over intake manifold air pressure as a function of the manifold air temperature;determining a second pressure rise in the combustion chamber over the first pressure rise as a function of a timing of fuel injection into the c...
