“…They developed a device to measure the friction force in these bearings. Clark et al (2009) measured piston pin surface temperature and pin rotation speed with a telemetry systems equipped with inductively powered transducers during an engine test. Takeuchi (2011) observed the behavior of the oil film formation and the cavitation between the piston pin and the pin boss with an ultrasonic technique in a real engine operating under low rotational speed.…”

Abstract:Running conditions for piston pin boss bearing have become very severe due to the high combustion pressure and piston temperature increase over the past ten years. The aim of this paper was to analyze the friction and lubrication characteristic of piston pin boss bearings and a connecting rod small end bearing. This paper provided a comprehensive analysis of piston pin based on a multi-body dynamic model which considers the oil film cavitation and structure deformation. Effects of different lubrication models, pin structures, and thermal deformation on the lubrication were discussed. The lubrication characteristics and performance parameters including oil film pressure distribution, asperity contact pressure, the minimum oil film thickness, the maximum oil film pressure, and friction power loss were listed. The results showed that the minimum oil film thickness was very different and the maximum oil film pressure was nearly the same. A parabola profile of pin bore can reduce the wear to some extent, and a flare profile intensified wear in some places and caused the wear to be concentrated on a smaller area. Reducing the inner diameters will reduce the wear of the pin boss. However, in a realistic design of the pin, avoiding high inertial force of the piston system and satisfying the demand for reliability of the pin, increasing the inner diameters and reliability is a 'trade off' problem. A suitable design of the hollow diameter is very important. The results can provide guidance for the design of the pin boss bearing.

“…This is followed by a pin motion study in a full-floating design, and two companion papers that revisit pressed pin designs (see Fletcher-Jones et al 1986;Clark et al 2009;Kondo and Ohbayashi 2012;Nishikawa 2012). The first is an older paper on a topic on which very little has been published.…”

“…Recently, analysis of thin-wall structures was carried out [7][8][9][10] in the presence of thermal and mechanical load considering various boundary conditions. Clark [12] and Fanghui [15] studied the free-floating piston pin behavior of heavy-duty engines'; further static responses of piston pin has been investigated by Debnath and Debnath [12]. The thermos-elastic analysis of piston was carried by Allmair and Sander [14].…”

In this article, authors discussed the various boundary conditions (fully floating, semi floating and stationary) and failure modes (transverse crack and longitudinal crack) of piston pin of IC engine. Moreover, authors given the empirical relations for shear stress, bending stress and ovalization stress to design piston pin for internal combustion engines. Furthermore, carried out the force analysis on piston pin and expressed the empirical relations for force analysis of piston pin that will be very useful for design of piston pin for petrol and diesel engines.
