FIELD: engines and pumps. ^ SUBSTANCE: electronic control system (10) of engine for piston pump consists of two (or more) pumps, equipped with crank drive (14) of both pumps (12). In the system there is not mechanical cam shaft, and its function is implemented with programme algorithm. Algorithm is under instruction and forms unique speed graph of output gear, which simulates speed graph of mechanical cam shaft. For practical purposes the speed graph of output gear is called cam profile since programme acts ass imaginable cam shaft. In the algorithm there used is evaluation of shaft crank angle, formation of under-instruction curve, smoothing and prediction. ^ EFFECT: decreasing speed fluctuation caused with unexpected abrupt pressure changes. ^ 5 cl, 4 dwg |
