Experimental study of a new method of improving charging efficiency 4-stroke internal combustion engine by an intensification of additional charging
As a development of B. P. Rudoy’s theory of gas exchange of internal combustion engines, a novel method of increasing the engine charging is experimentally investigated. The method provides the intensive charging of the cylinder by using the compression wave that is generated at the engine's exhaust. For this purpose, the engine includes the tuned intake and exhaust pipes, and the additional pipe to transmit waves there between, with two additional check valves installed at the air inlet. Comparative tests were carried out on the motor test rig. It is shown that the engine torque is increased by 9.8%.
