To improve the vibration and power of the engine, a sensitivity analysis of the operating parameters as well as the eccentricity between crankshaft centre and cylinder centre of the slider-crank-mechanism (SCM) are proposed and researched based on the SCM's dynamics model and the experimental data of the cylinder pressure in the internal combustion engine. An algorithm program developed in MATLAB environment is then applied to compute the dynamic equations of the SCM. The numerical simulation results show that the eccentricity , connecting rod length , and crankshaft radius are substantially affected the vibration and power of the engine. Particularly, with-0.01, the connecting rod length of {1.0-1.2}× , and crankshaft radius of {1.0-1.2}× could improve the vibration and increase the engine power.
Abstract. This paper introduces a green method of diaphragm spring's anti-rusting, which is of high quality, high efficiency and low consumption. It transforms the phosphating way of anti-rusting to physical anti-rusting that directly coat anti-rusting oil on the surface of the spring, and transforms the manual-oiling or oil-immersion to fully-automatically ultrasonic oiling. Hence, this method will completely change the way of diaphgragm spring's anti-rusting.
