Combustion

internal combustion engines. Petrol is a fossil fuel which can be known as a natural gas, petrol can also be referred to as propane. Propane is liquefied petroleum gas, its a product of both crude oil and natural gas. Because propane is derived from these two fossil fuels, its effect on the environment can be difficult to separate out. What is known is that is a reasonably clean-burning fuel compared to diesel and gasoline. When petrol is burnt it produces…

changed much in the last 60 years. While they have gotten faster, safer, and more efficient, there have not been any major changes in the technology used since the first cars were brought to market in the early 1900s. They still use an internal combustion engine, use gasoline as fuel, emit exhaust that harms the environment, require fueling up at gas stations, need oil changes, and have many moving parts, making it more likely something breaks and needs repaired. It is time to revolutionize the…

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…

take a lot of energy to power them. Now there are so many choices and different styles out there, there’s one for everyone. First you have to choose if you want an all electric (or plug in) or a plug in hybrid which is a half battery half regular combustion engine (gas engine). The all electric vehicles are meant for short travel like to work and back, or running errands around town, on average they get about 100 miles to a full charge (“Car and driver, pg.1”). The hybrid is good for either…

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…

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,…

concert. Like an orchestra conductor, the timing belt synchronizes all these components to make sure they are in rhythm, in the right place at the right time. How does the timing belt work? During normal engine operation, expanding gases from combustion cause the pistons to move up and down in the cylinders. The pistons, like your legs on a bike, “pedal” the crankshaft to ultimately transfer energy to the wheels. One or more camshafts (located in the cylinder…

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…

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…
