Performance Analysis of Four Stroke Diesel Engine Working with Acetylene and Diesel

Abstract

Limited reserve of fossil fuel and increasing pollution make it necessary to search for alternative fuels which can reduce dependency on petroleum based fuel. Gaseous fuel can be easily used as alternative fuel in IC engine in dual fuel mode. The previous studies in this field ware aimed to reduce pollution from exhaust gas. However, work in the field of acetylene gas effect on the vibration, noise and running cost of the diesel engine is still limited. In Present experimental work a setup is prepared to run an internal combustion engine in dual fuel mode using acetylene gas as an alternative fuel and to find out the effect of acetylene gas on performance and operating cost of diesel engine. The experiment is performed with different acetylene flow rate and on different loading condition on engine. This experimental work shows that use of small quantity of acetylene with intake air is can improve the performance and reduce the operating cost of engine. Based on the performance and cost analysis the acetylene flow rate is optimized to 0.068 kg/h.
