In Internal combustion Engines, the adequate cooling plays vital role for proper functioning and enhanced efficiencies. In the present scenario, the demand for Air cooled Engines with higher powers is increasing and hence necessity for Augmented heat transfer through fins. The present work confined to fins mounted on the cylinder block.In the present work, Internal Combustion Engine test rig is used, which consist of 4S, single cylinder, vertical, air cooled, SI Engine with Instrumentation panel, Throttle control mechanism and Electrical Loading system.The performance test on IC engine is carried out for three various configurations of cylinder blocks i.e., 1. Actual cylinder block 2.Cylinder block with triangular profile fins 3. Cylinder block with perforated triangular profile fins. Performance parameters are evaluated, plotted and compared & eventually conclusions are made.

This article discusses the issues of assessing the technical condition of the cylinder block. The necessary parameters for assessing the technical condition of the cylinder block have been determined. How and how to measure and calculate this or that parameter is presented in detail. Methods for calculating the parameters are presented. A measurement scheme and a technique for constructing a wear diagram of the inner diameter of a cylinder are proposed in order to visually assess the wear and its appearance. The method for calculating the repair size is presented. The questions of the influence of these parameters on the operability of the cylinder block and the internal combustion engine as a whole are considered.

Fuel Consumption Rate

Alternative fuel source such as ethanol possess great potential to replace conventional fuels such as petrol and diesel. There has been a great increase in the usage of such fuels in the developing world, of late, with many countries having already mandated the usage of ethanol blended petrol. In developing countries, two stroke internal combustion engines continue to be used for powering agricultural implements and auto rickshaws. This paper presents the experimental investigations carried out on the usage of petrol blended with different proportions of ethanol by volume (5%, and 10%) as a fuel for an unmodified and used 100cc two stroke SI engine. The objectives of the experimental investigations are to determine whether ethanol blended petrol can be used as a suitable fuel for the commonly used two stroke internal combustion engine without any modifications. Tests were carried out on the engine, with petrol as the fuel initially and then with ethanol blended petrol with increasing proportion of ethanol. The total fuel consumption rate seemed to increase upon addition of ethanol. However, the brake specific fuel consumption remained fairly constant. The fact that brake specific fuel consumption varies only marginally indicate that ethanol can be used as a substitute for petrol, as a fuel.

Swept Volume

The modification of the downsizing trend of internal combustion engines towards rightsizing is a new challenge for constructors. The change in the displacement volume of internal combustion engines accompanying the rightsizing idea may in fact mean a reduction or increase of the defining swept volume change factors and thus may affect the change in the operating characteristics as a result of changes in combustion process parameters - a research problem described in this publication. Incidents of changes in the displacement volume were considered along with the change of the compression space and at the change of the geometric degree of compression. The new form of the mathematical dependence describing the efficiency of the thermodynamic cycle makes it possible to evaluate the opera-tion indicators of the internal combustion engine along with the implementation of the rightsizing idea. The work demonstrated the in-variance of cycle efficiency with different forms of rightsizing.

This article discusses the issues of assessing the technical condition of the camshaft, internal combustion engine. The necessary parameters for assessing the technical condition of the engine camshaft have been determined. How and how to measure and calculate this or that parameter is presented in detail. Methods for calculating the parameters are presented. A scheme and method for measuring neck wear, determining the height of the cam, determining the beating of the central journal of the camshaft are proposed. The main defects of the camshafts are presented. The issues of the influence of these parameters on the operability of the camshaft and the internal combustion engine as a whole are considered.
