【Abstract】 The starting safety performance of internal combustion engines is an important indicator of safety requirements. As to the recoil starting equipment,many researchers in China adopts the equivalent security requirements of international standards and has clear numerical requirements to test the starting rope’s maximum force. How to determine the force is still a pending problem. In this paper,the influencing factors in the starting resistance torque of an internal combustion engine is analyzed; the calculation methods of inertia resistance moment,friction resistance moment and compression resistance moment is proposed; the variation of the calculated value that caused by the main influencing factors of starting performance is discussed. The comparison between the results and the relevant test data,a calculation method is drawn and verified to measure the rope force with the use of starting resistance torque. For a 186 FA diesel engine and 190F,168F,152F gasoline engines,the rope force of recoil starting equipment is calculated and analyzed,and the design and inspection of products in the industry of internal combustion engine will be based on the results of the calculation and analysis.更多还原
