The Three-cylinder Internal Combustion Pump Power Flow And Fluctuations In Operating Speed Simulation

The international combustion pump remains the traditional engine's chracteristics just like the mature technology and dependable work. As a new power system,the internal combustion pump gets rid of many problems that the engine-pump system and the hydraulic free piston engine has and can be industrialized easily. Three-cylinder combustion pump can conquer the defect of Single-cylinder internal combustion pump such as large power fluctation and low output power.This paper introduces the study backguound and the work pinciple of the Three-cylinder combustion pump, and then introduce the total mordel and the related parameters of the Three-cylinder combustion water pump.The power fluctuation of power piston, the pump, the crankshaft and the flywheel in a work cycle are simulated using Matlab programme. the result shows that the work condition of the Three-cylinder combustion water pump is more stablize than Single-cylinder internal combustion pump.The relation between the running unevenness and the influent factors it are simulated, just like the relation between speed fluctuation and the total mass of active part, the moment of inertia and the rotational speed, the related parameters used in this paper can also be validated .
