The Evolution of Jet Engines The jet engine is a complex propulsion device which draws in air by means of an intake‚ compresses it‚ heats it by means of an internal combustion engine‚ which when expelled it turns a turbine to produce thrust‚ resulting in a force sufficient enough to propell the aircraft in the opposite direction (Morgan 67). When the jet engine was thought of back in the 1920’s the world never thought it would become a reality‚ but by 1941 the first successful jet flight was

VALVETRONIC ENGINE TECHNOLOGY 1. INTRODUCTION The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers‚ which‚ even today‚ provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge

Current Dual-Fuel™ Technology Dual-Fuel™ is fitted onto a standard diesel engine‚ which operates unchanged‚ except power is generated by mostly clean natural gas. A measured quantity of natural gas is mixed with the air just before it enters the cylinder and compressed to the same levels as the diesel engine to maintain efficiency. The natural gas mixture does not ignite spontaneously under compression‚ so the Dual-Fuel™ engine uses a small injection of diesel fuel‚ around 10% of the total energy of

EN2702 Thermofluids – Petrol Engine Report Introduction At the end of 2010 it was estimated that there were 31‚035‚791 cars owned in the UK. (1) With cars being such a high contributor to the environmental problems that the planet is experiencing‚ it is of vital importance that our cars become as fuel efficient as possible‚ thus saving petrol and preserving the world’s fossil fuels. Around seventy-five percent of carbon monoxide emissions come from automobiles and in urban areas‚ harmful automotive

AIR DRIVEN ENGINE ABSTRACT: The Air Driven Engine is an eco-friendly engine which operates with compressed air. An Air Driven Engine uses the expansion of compressed air to drive the pistons of an engine An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion. An Air Driven Engine makes use of Compressed Air Technology for its operation The Compressed Air Technology

The Steam Engine and the Civil War Question: How did the Steam Engine influence the Civil War and America in itself? Throughout the Civil War‚ there were many people and inventions that positively influenced The Civil War‚ but none other than the steam engine. The steam engine was one of the most influential inventions of the Civil War and America in itself. Before the Steam Engine trade was limited and the American economy was doing very poorly. The causes of this were the rules of trade and

The Steam Engine The Genesis of the Steam Engine In the eighteenth century‚ people began to harness new resources to use to help with farm-ing. An English military engineer‚ Thomas Sav-ery‚ invented a water pump for mines. It later evolved into a coal-powered steam engine developed by Thomas Newcomen. Another man‚ James Watt‚ later improved Newcomen’s invention in 1764. The steam engine was the doorway to powering locomotives and steamships. Savery’s invent-tion‚ the water pump‚ was also known

Wankel Rotary Engine: A History by John B. Hege Well Done Conceived in the 1930s‚ simplified and successfully tested in the 1950s‚ the darling of the automotive industry in the early 1970s‚ then all but abandoned before resurging for a brilliant run as a high-performance powerplant for Mazda‚ the Wankel rotary engine has long been an object of fascination and more than a little mystery. A remarkably simple design (yet understood by few)‚ it boasts compact size‚ light weight and nearly vibration-free

Koenigsegg’s New Cam-Less Engine February 13‚ 2012 by Matt Jalopnik reports on an upcoming supercar from Swedish boutique automaker Koenigsegg that will feature a twin-turbo V8 engine whole valves are actuated without camshafts. Partnering with Swedish engineering firm Cargine‚ Koenigsegg plans to develop a valvetrain system whereby the valves are operated using pneumatic pressure alone. F1 car engines have used pneumatic valve springs since the Renault turbo engines of the mid-’80s‚ but always
