Patent ID: 7127345

Claim:
A multi-cylinder diesel engine providing enhanced performance in high ambient temperature and high altitude conditions comprising: a plurality of power cylinders; a piston reciprocating within each respective power cylinder; a fuel injection system injecting fuel into the cylinders in timed sequence with reciprocation of the respective piston; a throttle providing a power demand signal responsive to a plurality of discrete operator throttle input selections; a temperature sensor providing a temperature signal responsive to a temperature of air used for combustion of the fuel in the cylinders; a pressure sensor providing a pressure signal responsive to a pressure of the air; an engine speed sensor providing an engine speed signal responsive to an operating speed of the engine; a controller receiving the power demand signal, the temperature signal, the pressure signal and the engine speed signal; and programmed logic executable by the controller for generating an engine speed signal and a fuel injection control signal for cooperatively controlling both engine speed and timing of the injection of fuel into the respective cylinders in response to both the temperature and the pressure of the air.
