ABSTRACT:
Methods of operating a locomotive engine to maintain power and speed under conditions of air starvation, as in high temperature tunnel operation, include varying engine load instead of fuel rate to maintain set engine speed when operating at (1) excessive engine exhaust smoke levels or (2) under conditions where increasing fuel rate fails to increase engine power. Normal speed control by varying fuel rate is maintained under other operating conditions. Application to turbocharged two cycle diesel engines is particularly indicated.
