Bourke engine. The Bourke Engine was designed by Russell Bourke in the 1920s, as an improved two-stroke engine. Despite finishing his design and building several working engines, the onset of World War II, lack of test results,[1] and the poor health of his wife compounded to prevent his engine from ever coming successfully to market. The main claimed virtues of the design are that it has only two moving parts, is light weight, powerful, has two power pulses per revolution, and does not need oil mixed into the fuel.
Overview[edit] The Bourke engine is basically a two-stroke design, with one horizontally opposed piston assembly using two pistons that move in the same direction at the same time, so that their operations are 180 degrees out of phase. The pistons are connected to a Scotch Yoke mechanism in place of the more usual crankshaft mechanism, thus the piston acceleration is perfectly sinusoidal. This causes the pistons to spend more time at top dead center than conventional engines. Patents[edit] Engine configuration. Many apparently 'standard' names for configurations are historic, arbitrary, or overlapping. For example, the 180° V engine is so named because the crankshaft is related to a V engine more closely than it is related to other opposed-piston engines such as the boxer.
Others would consider it a flat engine because of its shape. Categorisation by piston motion[edit] Engine types include: The standard names for some configurations are historic, arbitrary, or both, with some overlap. For example, the cylinder banks of a 180° V engine do not in any way form a V, but it is regarded as a V engine because of its crankshaft and big end configuration, which result in performance characteristics similar to a V engine. Other categorizations[edit] By valve placement[edit] The majority of four stroke engines have poppet valves, although some aircraft engines have sleeve valves. By camshaft placement[edit] Poppet valves are opened by means of a camshaft which revolves at half the crankshaft speed.
Diesel engine (wikipedia) Diesel generator on an oil tanker A Diesel engine built by MAN AG in 1906 The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the heat of 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 engine has the highest thermal efficiency of any standard internal or external combustion engine due to its very high compression ratio. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.[1][2] Diesel engines are manufactured in two-stroke and four-stroke versions.
History[edit] Diesel's original 1897 engine on display at the Deutsches Museum in Munich, Germany Timeline[edit] IRIS engine. The IRIS Engine is a design for a new type of internal combustion engine. Its inventors say that engines constructed using this design can be smaller, lighter and significantly more efficient than traditional engines of comparable horsepower and displacement. The design replaces the piston and cylinder architecture of conventional engines with a purportedly novel mechanism called the Internally Radiating Impulse Structure, or IRIS.[1] In January 2008, the IRIS Engine design won first prize for transportation technology in NASA's annual "Create the Future" design competition.[1][2] In October 2008, the Radial Expansion Engine (RXE), a variant of the IRIS design, won a major award in the ConocoPhillips Energy Prize competition.[3] Geometry of the IRIS[edit] In an IRIS combustion chamber, a number of inverted segments of a circle, or "chordons," interact to create a continuously sealed chamber of variable volume.

Stirling engine (wikipedia) Alpha type Stirling engine. There are two cylinders. The expansion cylinder (red) is maintained at a high temperature while the compression cylinder (blue) is cooled. The passage between the two cylinders contains the regenerator. Beta type Stirling engine. Originally conceived in 1816 as an industrial prime mover to rival the steam engine, its practical use was largely confined to low-power domestic applications for over a century.[3] The Stirling engine is noted for its high efficiency compared to steam engines,[4] quiet operation, and the ease with which it can use almost any heat source. Name and classification[edit] Robert Stirling was a Scottish minister who invented the first practical example of a closed cycle air engine in 1816, and it was suggested by Fleeming Jenkin as early as 1884 that all such engines should therefore generically be called Stirling engines.
History[edit] Invention and early development[edit] Later nineteenth century[edit] Twentieth century revival[edit] Swing-piston engine. A swing-piston engine is a type of internal combustion engine in which the pistons move in a circular motion inside a ring-shaped "cylinder", moving closer and further from each other to provide compression and expansion. Generally two sets of pistons are used, geared to move in a fixed relationship as they rotate around the cylinder. In some versions the pistons oscillate around a fixed center, as opposed to rotating around the entire engine. The design has also been referred to as a oscillating piston engine, vibratory engine when the pistons oscillate instead of rotate, or toroidal engine based on the shape of the "cylinder". This type of engine is regarded as a major candidate mechanism to solving the energy crisis.
Two successful models have been made: The American made MYT engine and a Russian ORE which was used in the Yo-Mobile hybrid car.
