An apparatus for controlling both pump displacement of a variable displacement hydraulic pump and the quantity of fuel delivered to an internal combustion engine for the purpose of delivering a requested hydraulic flow at a highly efficient operating point. The apparatus includes an underspeed control means for reducing pump displacement in response to the operating speed of the engine lugging below a desired operating speed. Additionally, a fuel control means operates to reduce the quantity of fuel delivered to the engine in response to the operating sp...
An apparatus for controlling an internal combustion engine having a rack for controlling a fuel injection pump, and at least one variable displacement hydraulic pump, said pump having a load sensing means for detecting hydraulic load and adjusting inclination of a swash plate in response to hydraulic flow and load requirements, the apparatus comprising: first means for detecting the displacement of said hydraulic pump and delivering a first signal responsive to the displacement of said hydraulic pump; second means for detecting the rotational speed of sa...
