Rotary Engine – Huge Power in a Small Box According to Philip’s Encyclopedia Wankel rotary engine or just Wankel engine is “Internal combustion engine with rotors instead of pistons.” That not so popular engine is actually about two times lighter than a four cylinder piston engine‚ the one that we all have in our cars‚ for the same power output. It also has four times less moving parts. Much simpler‚ much lighter‚ much smaller it has numerous advantages over a conventional piston engine.

Green Engine seminar report.DOC (Size: 107 KB / Downloads: 3197) ABSTRACT The green engine is one of the most interesting discoveries of the new millennium. It has got some unique features that were used for the first time in the making of engines. This engine is a piston less one with features like sequential variable compression ratio‚ direct air intake‚ direct fuel injection‚ multi-fuel usage etc. The efficiency of this engine is high when compared to the contemporary engines and also the exhaust

Turboprop engines Turboprop engines are a type of aircraft powerplant that use a gas turbine to drive a propeller. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’s exhaust gases contain little energy compared to a jet engine and play a minor role in the propulsion of the aircraft. The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚

confused with the catapult. The Mangonel is believed to be invented by the Romans in 400BC. During the Medieval age the engine was used most by the French. It’s named Mangonel because the Latin word manganon means “an engine of war”. Mangonels were referred to as scorpions because the arm of the engine was like the tail of the animal. The Mangonel wasn’t as accurate as other siege engines but did go a greater distance. The Mangonel has a long arm attached to a bowl like bucket. The base had wheels so

The Jet Engine and the Revolution in Leisure Air Travel‚ 1960-1975 Peter Lyth Air transport for European tourists got off to a shaky start in the late 1920s. 1 But it was to be thirty years before leisure air travel was to appeal to anyone but the rich and adventurous. High cost‚ fear of flying and the absence of toilets in early airliners (an unfortunate combination) were the main deterrents; the unpressurized aircraft of the inter-war years were noisy‚ slow and not especially comfortable

Six-stroke engine The six-stroke engine is a type of internal combustion engine based on the four-stroke engine‚ but with additional complexity intended to make it more efficient and reduce emissions. Two types of six-stroke engine have been developed since the 1990s: In the first approach‚ the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air

The invention of the internal combustion engine is most probably the result of the developments of several individuals. Around 1780‚ Dutch scientist Christiaan Huygens built an engine that used gunpowder as a fuel‚ but this engine was far too dangerous to be practical. His assistant‚ Denis Papin‚ also experimented with developing an internal combustion engine‚ building a simple steam-powered device around 1790. Again‚ this engine was not practical‚ and not until the early nineteenth century did the
