Combustion

compression-ignition engine) is an internal combustion engine that uses the compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engines have the highest thermal efficiency in any internal or external combustion engine because of its very…

internal combustion engine. Diesel believed by implementing Carnot’s theoretical ideas he could create an engine that was four times more efficient than those currently available. In 1885, Diesel began to think and design his engine and to complete his ambitious idea (Jaaskelainen,…

topics Until recently, the electric car was seen as anecdotal and some serious contender against the powerful gasoline. The reasons must be sought in the skepticism of a poorly informed citizenry . "Not long ago we had in the magazine a separate cars combustion to discuss electric models section, the reader seen as a rarity," recalls Cano, "today we no longer distinguish our…

Abstract— The present study was made to evaluate the performance of Braysson cycle. Braysson cycle is a hybrid gas turbine, combination of Brayton cycle and Ericsson cycle. The hybrid gas turbine is proposed based on the Brayton cycle at high temperature heat addition and low temperature heat rejection at Ericsson cycle. The performance was evaluated in terms of thermal efficiency, exergy losses and specific power output. Energy and exergy analysis was carried out on Braysson cycle and Brayton…

(HYBRID ENGINE) What is meant by hybrid ? In mechanical language Hybrid is something that is powered by two or more source of energy. What is a hybrid car? A car or a vehicle with the combination of an internal combustion engine with one or more electrical motors powered by a battery. Or We can say that a car with two power plants is hybrid. A hybrid car is one that uses more than one means of propulsion ,that means a couple of a normal petrol or diesel engine with an electrical motor. HISTROY:…

Heywood J.B. [1] defines internal combustion engine as a machine that works converting chemical energy, present in the fuel, to mechanical energy. This kind of machine is used to generate power and make human life easier. Also engine is used in large scale around the word. However the fuel used in engines is a controversial discussion because it is from nonrenewable resources, which are being depleted at a rapid rate. Moreover, the combustion of fossil fuel releases many emissions in the…

James Watt was a Scottish inventor, mechanical engineer and chemist. He is famous for developing a separate condensing chamber for the steam engine. This invention greatly improved the efficiency of the steam engine and played a considerable role in advancing the role of steam engines in the Industrial revolution.He was born in Greenock, Scotland on 18 January 1736. Initially Watt worked as a maker of mathematical instruments, but later found himself working with steam engines. At the University…

Electrically powered cars will be critically important in the future. There are many reasons why electrically powered cars will be a more efficient and eco-friendly form of transportation. Oil will become an unpopular form of fuel in the future due to the fact that there is a very limited supply, even now in present time, we have to find new methods of getting every last drop of oil. We will eventually run the world dry of oil and then we will have no other choice than to find a new source of…

Annotated Bibliography This study focused on the methods of improving a turbocharger’s efficiency at low engine RPMs through the use of steam. Other methods of increasing turbocharging efficiency include two-stage turbos and electrically assisted turbos; however, steam was determined to be the most efficient. The authors determined that by injecting steam into the turbine rather than exhaust gases at low RPMs, engine performance “can be increased by 25.0% over the exhaust turbocharging…

Then the compressed air is combined with compressed fuel. The combustion of these components at a very high temperature causes the gases to expand rapidly causing a significant thrust to come from the engine. In turbojet engines, this thrust causes the entire force of the engine while in some it does not. . Turboprop…
