This paper presents a model for the calculation of in-cylinder parameters in an internal combustion engine with a noncircular gear based modified crank-slider mechanism. With the introduction of noncircular gears, the instantaneous velocity of the piston can be accommodated to improve combustion performance. The displacement law of the noncircular gears is obtained using a B-spline curve, so that the appropriate instantaneous velocity of the piston is obtained. The gas pressure and temperature required for the determination of mechanical and thermal loads on engine components are found. The influence of the noncircular gears on the loads that act on all the components of the crank-slider mechanism, as well as the theoretical output torque for a given geometrical structure and inertial properties, are presented. To obtain the pressure and temperature inside the cylinder, under different operating parameters, such as air fuel ratio and spark angle advance, a Zero dimensional model is applied. The proposed mechanism enables the optimisation of the combustion cycle; therefore, greater power may be achieved. [via]
