Comprehensive Experimental Examination On Diesel Engine Supplied With Kanuga Methyl Ester Essay

Chevron products Company, a Chevron U.S. A Inc. division, maker of the Delo(R) brand of technologically advanced heavy duty engine oils, lubricants and coolants, unveiled a new category of heavy duty motor oil designed to address the growth of severe duty applications in on-and off-highway markets. Quality heavy-duty engine oils must also disperse soot and control sludge in order to help guard against the loss of an engine’s life. Properly lubricating the inside of a heavy-duty engine requires more than just creating a protective film. Delo products have assisted in reducing operating costs and improving fuel efficiency. Switching to this product Delo 's fuel economy products, and a 4% fuel economy improvement compared to SAE 15W-40 oils. Actual results will vary depending upon vehicle type, load and other driving conditions [4].

Ethanol is now used as a fuel for vehicles in its pure form as a replacement for petrol, where it is blended with petrol to improve the vehicles emissions and power. The substitution of ethanol for petrol in cars and light vehicles in Brazil is one of the largest commercial

Motor vehicle use is now generally recognised as the source of more air pollution than any other single activity in cities around the world. The internal combustion engine of a vehicle produces power by burning fuel and changing the chemical energy of fuel into heat energy. The heat energy is then converted into mechanical power. Cars and trucks do not burn all of the fuel that goes into the combustion chamber. In fact, most vehicles only burn about 85% of the fuel and as the vehicle gets older less and less fuel is burned. It is this unburned fuel that produces some harmful products which are discharged from the engine and become air pollutants.[iv] Therefore, an engine’s fuel system, and its emission controls are closely interrelated. That is why attention is given to the requirements of emission control in the design and operation of all parts of the fuel system in a vehicle.

In recent years increasing interest to methanol as an effective means to produce a ecologically clean fuel, available and cheap raw materials for the synthesis of various hydrocarbons and products of their processing. The most accessible and cheap raw material for the obtaining of CH3OH are natural and associated gases, from which by Fischer-Tropta's method it is possible to obtain hydrocarbons of different composition and structure. The formation of gasoline from methanol, developed in the present time flows through the stage of formation of DME, which turns further into the mixture of hydrocarbons consisting more than 50% of the valuable branched paraffins. Such "methanol" fuel in their composition does not contain sulfur and nitrogen compounds and a minor amount of aromatic compounds. Now, methanol increasingly became used as fuel and also as additives to motor fuels (from 3 to 65%). Methanol increases the octane level of fuels and reduces harmful emissions into the atmosphere. Based on the methanol it is possible to obtain alternative pollution-free fuels such as dimethyl ether (DME) and dimethoxymethane (DMM).

Diesel experts know the execution of your consideration including everything from admissions to your fumes and turbochargers. They will work a considerable measure quicker and more productively than a customary auto

Gasoline and diesel vehicles have been around for a long period of time ever since they were first designed around the 1930’s. The diesel market is in the middle of a revolution. Over the years that diesel has been around there are new enhancements that are increasing engine power and torque, lowering emissions and enhancing fuel economy, creating new and cleaner diesel vehicles. Through advancements in technology, gasoline and diesel powered vehicles have evolved since they were first designed to become more environmentally friendly.

Diesel and gasoline engines have been each other’s competition since the 1930’s when the first diesel run car was produced. There is one main mechanical difference between these two engines; a gasoline engine ignites the gasoline with spark plugs, a lighter of sorts, and the diesel engine ignites the diesel by compressing it so much that it spontaneously combusts. Although there are a few other types of engines now, such as hybrid or electric, diesel is still superior to these.

The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed.

Diesel engines began to be used in automobiles in the 1930s. They are used in many trucks, ships, buses and small passenger cars in Europe right now.[1] Many believe that diesel engine are heavier, noisier and generate black smock when running. However, diesel engine’s unique advantages can make them the engine of the future for vehicles. And with much more stringent standard to take effect in the future, diesel engine’s emissions and control technologies are still very much in the forefront. This paper will cover the developments in diesel vehicles emission regulation and control technology for NOx, particulate matter (PM) for diesel vehicles.

The use of ethanol as an alternative fuel for gasoline has attracted considerable interest, mostly in the US (corn-based ethanol), Brazil (sugar cane-based ethanol); and Sweden as E85 (15% gasoline-85% ethanol) has been commercially used for a couple of decades [129]. Ethanol is also used as a drop–in fuel up to 10% in gasoline (E10) in a number of markets such as Austral-ia [96]. There are a number of advantages of blending ethanol in gasoline: (1)

In our world today diesel engines have become a substantial part of the society, being used in buses, trucks, locomotives, tractors, and so on. Scientist has been seeking ways of improving the efficiency of diesel engines by developing and testing alternative fuels. Recent studies explore the use of diesohol as a substitute to diesel. Diesohol are classified as “a mixture of diesel fuel and anhydrous alcohol blended using a chemical emulsifier,” (Environmental Protection Agency, 2003).However a major concern regarding diesohol is both alcohols and diesel have dissimilar physical and chemical properties. Alcohols due to it being an oxygenate proved to burn cleanly and easily, and produce decreased amount of soot and harmful emissions (Mithun Mohan,2015) .It is estimated its combustion is around 3000 kJ/kg (The Engineering ToolBox, Unknown),(Mitun Mohan,2015).The chemical equation for the combustion of alcohols :

The ever increasing carbon emissions from the automobiles all around the world has forced the incorporation of novel , more sustainable means of non-conventional fuels for the automobiles like the hybrid cars , solar vehicles , the use of gasohol and alcohol based fuels is also considered as an alternative for the conventional fuels and also the development of solar electric hybrid vehicle. There are a lot of possibilities and feasible solutions for lowering the carbon emissions from vehicles.

The functional unit of the study is 300,000 km travelled by the diesel engine. The fuel efficiency of the engine is 0.250 litres per km. It is assumed that the fuel efficiency of both engines is equal.

In spite of the fact that higher BSFC of n-butanol/diesel fuel the enhancement, oxygen content of the fuel blends gives higher BTE. The improvement in BTE can be referred to the enhanced oxygen content, which helps improvement in combustion, particularly during the diffusion combustion phase. Another influence factor that affects the BTE is cetane number. Lower cetane number of the BA-diesel fuel blends causes of the

Advantages: Biodiesel produce significantly lesser amount of emissions compared to petroleum fuels. It results in much less air pollution due to its higher oxygen content and lack most components contributing to the formation of pollutants. The one exception to this is nitrogen oxide emissions, which tend to be slightly higher when using biodiesel. Proper tuning of the engine can minimize this problem. Based on engine testing, using the most stringent emissions testing protocols required by Environment Protection Agency (EPA) for certification of fuels or fuel additives in the USA, the overall ozone forming potential of the hydrocarbon emissions from biodiesel was nearly 50 % less than that measured for petroleum diesel fuel. This trait of biodiesels could be able to contribute in reducing global warming which currently is getting the attention of world.
