Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...

Because of high pressure fluctuations in Combination Electronic Unit Pump (CEUP) system during fuel injection cycles, physical properties of diesel fuel including density, acoustic wave speed and bulk modulus also vary. These physical properties of fuel have significant importance in predicting the fuel injection behavior and its optimization. A 1D viscous damped mathematical model of wave equa...

This paper presents an experimental investigation into the detection of excessive diesel knock using acoustic emission (AE) signals. Three different dual-fuel diesel engine operating regimes were induced into a compression-ignition (diesel) engine operating on both straight diesel fuel and two different mixtures of fumigated ethanol and diesel. The experimentally induced engine operating regime...

Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in m...

Biodiesel is an alternative diesel fuel that can be produced from different kinds of vegetable oils. It is an oxygenated, non-toxic, sulphur-free, biodegradable, and renewable fuel and can be used in diesel engines without significant modification. However, the performance, emissions and combustion characteristics will be different for the same biodiesel used in different types of engine. In th...

In today’s scenario, researchers around the world are looking for ways to develop alternate forms of fuel. With the ever-rising fuel costs, developing alternate energy is a top priority. Biodiesel was developed to combat the high gas and oil prices. It is especially made for use in diesel cars and trucks. Biodiesel can be made from all Natural foods that can produce oil. Virtually all oils that...

Availability analysis is an effective approach to studying energy conversion in systems and identifying inefficiency. In the present study, a single-zone model was used to examine energy performance parameters and heat release rates. The governing equation of availability analysis was applied in the model, and the possibility of using biodiesel produced from sunflower oil as diesel engine was i...

The main objective of this paper to discuss the research output for getting better engine performance with lower noxious emissions by improving the fuel quality. The control of diesel fuel properties as a means of Regulated pollutants continues to be charged with reaching various air quality goals. Some additives play effective role in diesel fuel for improving fuel‟s quality and minimize the p...

All countries in Europe have road fuel taxes and these account for roughly half of the net fuel price. We compare current road fuel taxes and corrective taxes, estimated on the basis of negative externalities from road transport for 22 European countries, taking into account the effect of fuel taxation on fuel efficiency. We focus on cars running on diesel or petrol and commercial vehicles runn...

•• Mr. Taniguchi, would you please begin by explaining the general background leading to the development of the V3300 Series of diesel engines? KT: Our basic idea was, in the first place, to concentrate on in-house usage, specifically to develop a series of engines ideal for being mounted on tractors. It was realized that with in-house mounting being the primary application for such engines, it...
