【Abstract】 This paper described property of the test equipment. 2. The principles of the design for the prot of a long stroke reverse-loop scavenging diesel has been drawn out of our simulating tests. 3. A correcting of the mathematical model indicating the relation between the scavenging efficiency and the scavenging ratio has put forward. A method has also been elicited by which the parameter of the given model b1 and b2 has been prescribed in the light of probability theory.更多还原
