The Fuel Consumption of the Integrated Piston-Plunger Pump

The fuel consumption of the integrated piston-plunger pump was studied through experiments. The integrated piston-plunger pump integrated piston engine and plunger pump technology as a whole, makes use of piston linear motion to drive plunger output water pressure energy. The optimal fuel consumption working zone and economic curve were obtained compared with piston engine driving plunger pump. The fuel consumption in total working conditions is lower than piston engine driving plunger pump by 11~40.88%. The same fuel consumption level contains wider working condition than piston engine driving plunger pump system. The lowest fuel consumption of the integrated piston-plunger pump in different throttles is between 292g/(kWh) and 420 g/(kWh), and corresponding rotational speed is about 1400 r/min.
