Abstract
Cavitating Fuel Flows in Hypocycloid Pump from the Perspective of Applying the Effect of Gas Desorption from the Solution with Nucleation of Gas Bubbles
Highlights
One of the most serious problems of the modern compression-ignition engines is the excessive emission of harmful substances in the exhaust gases
It was assumed that the fuel will be discharged by the hypocycloid pump at a pressure of 150 MPa in order to evaluate the influence of the effect on the possibility that cavitation nuclei will form with a certain surplus
Utilization of the effect that accompanies the release of gas dissolved in the fuel is the most important mechanism planned for application in the newly designed, original pump with hypocycloid power transmission
Summary
One of the most serious problems of the modern compression-ignition engines is the excessive emission of harmful substances in the exhaust gases. In the standard injection pump solutions, the amount of air dissolved in the Diesel fuel is within the range of several percent – even such a small fraction of the entire fuel volume has an effect on the system’s operation, causing the cavitation erosion.
