In this study the performance and emissions characteristics of a heavy-duty, direct injection, Compression ignition (CI) engine which is specialized in agriculture, have been investigated experimentally. For this aim, the influence of injection timing, load, engine speed on power, brake specific fuel consumption (BSFC), peak pressure (PP), nitrogen oxides (NOx), carbon dioxide (CO2), Carbon mon...

The increased number of automobiles in recent years has resulted in great demand for fossil fuel. This has led to the development of automobile by using alternative fuels which include gaseous fuels, biofuels and vegetables oils as fuel. Energy from biomass and more specific bio-diesel is one of the opportunities that could cover the future demand of fossil fuel shortage. Biomass in the form of...

New and exciting possibilities in vehicle control are revealed by the consideration of topography through the combination GPS and three dimensional road maps. This thesis explores how information about future road slopes can be utilized in a heavy truck with the aim at reducing the fuel consumption over a route without increasing the total travel time. A model predictive control (MPC) scheme is...

The technical analysis conducted in this study deals with the modelling of diesel engine exhaust emissions using artificial neural networks. Objective of this study is to understand the effectiveness of various biodiesel fuel properties and engine operating conditions on diesel engine combustion towards the formation of exhaust emissions. The experimental investigations have been carried out on...

To improve the combustion and emission characteristics of diesel engines, methanol-diesel fuels with different mixing ratios (DM0, DM10, DM20, DM30, DM40) were used to investigate effects methanol addition on a four-stroke engine in terms cylinder pressure, brake power, brake-specific fuel consumption, nitrogen oxides, soot, carbon monoxide emissions. Firstly, an improved entire model was devel...

Gas-to-liquid (GTL) fuel is regarded as a promising alternative diesel fuel. It can be used either directly as a diesel fuel or in blends with petroleum-derived diesel or biodiesel. This study investigated the fuel properties, engine performance and exhaust emissions of B5 diesel, GTL fuel and their blends. The main fuel properties of the blended fuels showed a linear variation with the fractio...

The present investigation summarizes detailed experimental studies with standard lubricants of commercial quality known as Racer-4 of Hindustan Petroleum Corporation (India) dispersed with different mass concentrations of nanoparticles of Cu and TiO2. The test bench is fabricated with a four-stroke Hero-Honda motorbike hydraulically loaded at the rear wheel with proper instrumentation to record...

This paper presents performance study of Peugeot MM540 diesel engine using biodiesel prepared from used cooking oil. Transesterification process is followed to produce bio diesel and is blended with diesel in different proportion of 22:78 and 24:76 by volume and named as blend B22 and B24 respectively. Engine was run at different loads (0, 15, 30, 35, and 40kg) with constant speed of 1000rpm se...

The current research work on the effect of exhaust gas recirculation diesel engine for analysis performance and emission characteristics with corn oil methyl ester blends. was tested three fuels are 100diesel, 20B (20%COME + 80% Diesel) 40B (40%COME 60% EGR condition 0% 20% rate. evaluated such as thermal efficiency, brake specific fuel consumption, temperature emissions carbon dioxide, hydroca...

Use of biodiesel as an alternative to diesel could reduce the dependency on petroleum products and the pollution problem. The physical properties of the fuel such as viscosity, volatility and f lash point also affect the combustion process, thereby engine performance. Specif ically atomization of the fuel during the injection is attributed to higher viscosity of biodiesel. Injec ted fuel drople...
