Abstract

Diesel engines are widely used for their low fuel consumption and better efficiency. Ever increasing diesel consumption, large outflow of foreign exchange and concern for environment have prompted developing countries like India. Recently, because of increases in crude oil prices, limited resources of fossil oil focus on nano additives in diesel engines. In this study, performance tests were carried out on diesel engine with neat diesel fuel; diesel with 10ppm cerium oxide nanoparticle blend and 30ppm and 50ppm blend with as additive.

The effects of the additive cerium oxide nanoparticles on the engine performance and emissions are studied, and comparisons of the performance of the fuel with and without the additive are also presented. The experimental results revealed a substantial enhancement in the performance and a reduction in harmful emissions.

Abstract

In this project optimal trajectory and path planning of mobile robot, which is working in a fixed & moving obstacles area was programmed. The problem has a multi-criterion character in which three objective functions were used. The objectives are optimal trajectory planning in a moving obstacles area, minimum mechanical energy of the actuators and optimal path planning in a fixed obstacle area. Existing algorithms are not able to perform efficiently in the moving obstacles area, it`s not able to select the optimum path, if it`s able to do that means it requires more memory storage and mechanical power. Then it has minimum capability of handling multi tasking problems which is required for practical application. In order to overcome the above drawbacks all the objectives want to be optimized, for that purpose non domination solution is required. So NSGA-2 (non-dominated sorting genetic algorithm-2) is used here to solve that domination problem by calculating the Pareto set values, best non dominated optimal solution is find out by applying it to the real problem best solution is obtained.

Abstract

The idea of using vegetable oils as fuel for diesel engines is not new. With the advent of cheap petroleum, appropriate crude oil fractions were reined to serve as fuel and diesel fuels and diesel engines evolved together. In the 1930s and 1940s vegetable oils were used as diesel fuels from time to time, but usually only in emergency situations. Recently, because of increases in crude oil prices, limited resources of fossil oil and environmental concern there has been a renewed focus on vegetable oils and animal fats to make biodiesel fuels. Diesel engines have proven their utility in the transportation, agriculture, and power sectors in India. They are also potential sources of decentralized energy generation for rural electrification. Concerns on the long-term availability of petroleum diesel and the stringent environmental norms have mandated the search for a renewable alternative to diesel fuel to address these problems. In this study, performance tests were carried out on diesel engine with neat diesel fuel and biodiesel mixture. Biodiesel was made by transesterification process. Karanja oil was selected for biodiesel production. Fuel blends were tested in a single cylinder, direct injection, water cooled diesel engine (agricultural). The effects of B30,B30 with Bio Fuel additive and commercial diesel on the engine power, engine torque, BSFCs and exhaust gasses temperature were ascertained by performance tests. The influence of blends on CO, NOx,and CO2 emission were investigated. The experimental results showed that the use of Biodiesel improve the performance parameters and decrease the CO emission as compared to diesel fuel. Bio Fuel Enhancer(BFE) not only improve the performance and also increase fuel saving and reduce the NOx.
