Research of the efficiency using the model of the spatial hinge in an internal combustion engine

Abstract

An internal combustion engine is a heat system for many kinds of use in the field of engineering. The difficult economic situation around petroleum products, which is associate with their deficit and modern environmental safety standards require switching to alternative energy sources and looking for ways to modernize internal combustion engines to increase their efficiency. A large number of internal combustion engines belong to the crank group. The analysis of the crank group showed their low technical efficiency. When the piston is in the upper position at the time of ignition of the combustible mixture in the cylinder, the maximum pressure occurs. This leads to maximum driving force with a minimum crank angle. Also increases the friction of the piston on the cylinder wall, the wear of the cylinder wall, additional local heating of the surface of the cylinder and over-load of the crankshaft. Thus, a decrease in the net power resulting from the combustion of fuel in the engine occurs. To increase the efficiency of the crank mechanism, it is propose to apply a new design of the torque transmission mechanism in the engine, which will be built based on a spatial hinge. This paper presents a study of the power and kinematic parameters of the spatial hinge of an internal combustion engine.
