Abstract:Dual
Fuel Engines are engines which have capable of running by taking two fuels. On internal combustion engines, one of the fuel is gasoline, and the other is an alternate fuel such as natural gas (CNG), LPG, or hydrogen etc. The two fuels are stored in separate tanks and the engine runs on one fuel at a time. Dual Fuel Engines have the capability to switch back and forth from gasoline fuel to the other fuel, manually or automatically. A dual fuel engine kit consists of Adapter, Shut off valve, gas injector, porting tool, pressure regulator, coalescing filter and Actuators. This project deals with fabrication of dual fuel engine and practical experimentation on efficiency and working operation of Dual Fuel Engine and implemented it in a 2-wheeler motorbike engine. After fabricating the engine with the kit, other accessories were fabricated. when the set up is done, we need to carry out performance test by first taking petrol as a fuel and then taking LPG as a fuel. Then, we need to compare both the results and conclude on the effectiveness of individual fuels and the advantage of using the dual fuel engine. Keywords: Dual fuel Engine, Kit, Efficiency etc
1.0 Introduction Dual-fuel engines (Bi-fuel engines) are multi-fuel engines which have capable of running by taking two fuels. On internal combustion engines one fuel is gasoline or diesel, and the other is an alternate fuel such as natural gas (CNG), LPG, or hydrogen. The two fuels are stored in separate tanks and the engine runs on one fuel at a time in some cases, in others both fuels are used in unison. Bi-fuel vehicles have the capability to switch back and forth from gasoline or diesel to the other fuel, manually or automatically. The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Auto-gas (LPG), followed by natural gas (CNG), and it is used mainly in Europe. The Netherlands and the Baltic states have a large number of cars running with LPG. Italy currently has the largest number of CNG vehicles, followed by Sweden. They are also used in South America, where these vehicles are mainly used as taxicabs in main cities of Brazil and Argentina. Normally, standard gasoline vehicles are retrofitted in specialized shops, which involve installing the gas cylinder in the trunk and the LPG or CNG injection system and electronics.
1.1 Literature Review
Maneesh Kumar Dubey and Ravindra Randa[1] did an experiment on Experimental Performance Analysis of Single Cylinder Two Stroke Petrol Engine using Gasoline and LPG. Their work shows a comparison of performance by using petrol and LPG at no load and different load condition. The experiment also shows that LPG gives maximum Brake Thermal Efficiency (BTE) at 50% of load and 31.32% less Fuel Consumption (FC) than petrol at load, low Brake Specific Fuel Consumption (BSFC), low Brake Specific Energy Consumption (BSEC) than petrol at the loading condition of the engine.. R.R. Saraf, S.S.Thipse and P.K.Saxena[2] studied the Comparative Emission Analysis of Gasoline/LPG Automotive Bifuel Engine. This paper presents comparative emission study of newly introduced gasoline/LPG bifuel automotive engine in Indian market. Dheeraj Kalra, Dr.Veeresh Babu A and M. Vijay Kumar[3] studied the Effects of LPG on the performance and emission characteristics of SI engine.According to them, IC engines are considered as major contributors to the deterioration of the environment, therefore there is an increasing demand to go for alternative fuels for both SI and CI engine so as to maintain the ecological balance as well as reduce dependency on petroleum and socio economic aspects. The gaseous fuel such as LPG has been widely used throughout the world in SI engines as it impacts greenhouse emissions less than any other fossil fuel. Siddharth Shukla and Pranav Ravi [4] did an experiment on Working and Performance Analysis of Gasoline Fuelled Engine with Biogas.Their study concluded that efficient utilization of biomass is a much needed requirement.
