EFFECT OF PREHEATED FUEL ON I. C. ENGINE VARYING COMPRESSION RATIO– A REVIEW

Mechanical ( Thermal Engineering )

Diesel is very important in the field of automation and power plant. The exhorting advancements in future ought to upgrade technology with regards to power, gas economy and emission. Modified technology can improve the efficiency of engine run by diesel fuel. The gas inlet temperature also can effect in engine parameter. By preheating fuel technology, engine efficiency is improved. In the current literature review work, two sections are provided. One section give brief idea about modified preheating techniques and their effect on performance on ic engine. Second section covers importance of compression ratio on fuel consumption and efficiency of an engine. Through the literature survey it is clear that preheating regarding fuel is beneficial technology to further improve the overall performance and emission associated with an engine. Compression Ratio associated with an engine has important position on performance associated with an engine. Combine effect of preheating of fuel and variation compression ratio can make an i c engine more stable and more capable by which fuel consumption reduced. As the compression ratio increases, it will reduce CO and HC emission and increase NOx emission. Preheating increase BSFC and BTE of an engine which is beneficial to increase efficiency. To increase the fire point of fuel, mostly blends are used so that their fire point temperature increases but it reduces the efficiency. Optimum mixtures between inlet gas temperature and compression ratio can be find out to boost the overall performance and slow up the emission associated with an VCR engine. In this particular literature examine work, a diverse type of IC engines are covered.
