 Controlled Combustion Engine - Wikipedia, the free encyclopedia
Controlled Combustion Engine (CCE) is a type of internal combustion engine designed by Brad Howell-Smith in 1995.
It is around a quarter the size and weight of a conventional engine of similar output and uses fewer moving components.
Because the piston assembly only moves in one dimension (unlike the case in an engine with connecting rods), contact with the cylinder wall in minimised, which reduces wear and lubrication requirements.

 Internal combustion engine
All internal combustion engines depend on the chemical process of combustion and explosion, that is the reaction of a fuel with oxygen.
An engine's capacity is the displacement or swept volume by the pistons of the engine.
Engines of lesser quality would typically have the torque peak at a lower value and a lower engine speed, though it should be noted that an engine designer can place the peak of the torque curve more or less anywhere he chooses, depending on the engine's application.

 MSN Encarta - Internal-Combustion Engine
Four principal types of internal-combustion engines are in general use: the Otto-cycle engine, the diesel engine, the rotary engine, and the gas turbine.
The Otto-cycle engine, named after its inventor, the German technician Nikolaus August Otto, is the familiar gasoline engine used in automobiles and airplanes; the diesel engine, named after the French-born German engineer Rudolf Christian Karl Diesel, operates on a different principle and usually uses oil as a fuel.
The fourth stroke, as in the Otto-cycle engine, is an exhaust stroke.

 internal-combustion engine. The Columbia Encyclopedia, Sixth Edition. 2001-05
Such engines are classified as reciprocating or rotary, spark ignition or compression ignition, and two-stroke or four-stroke; the most familiar combination, used from automobiles to lawn mowers, is the reciprocating, spark-ignited, four-stroke gasoline engine.
The composition of the mixture is regulated by the throttle, an air valve in the intake manifold that varies the flow of fuel to the combustion chambers of the cylinders.
Four-stroke engines are lubricated by oil from a separate oil reservoir, either in the crankcase, which is a pan attached to the underside of the engine, or in an external tank.

 Internal-combustion engine   (Site not responding. Last check: 2007-11-05)
Jet engines and gas turbines use internal combustion, but the term 'internal-combustion engine' is normally used only to refer to engines in which combustion is intermittent (and usually featuring reciprocating machinery).
The most common internal combustion engines are the gasoline powered engine and the diesel engine.
The combustion of the fuel results in the generation of heat, and the hot gases that are in the cylinder are then at a higher pressure than the fuel-air mixture and so drive the piston back down.

Human power was focused by the use of simple engines, such as the capstan, windlass or treadmill, and with ropes, pulleys, and block and tackle arrangements, this power was transmitted and multiplied.
In the broadest sense of the term, internal combustion engines can be said to have been invented in China, with the invention of fireworks during the Song dynasty, with some sources putting this invention a thousand years earlier still.
For more conventional, reciprocating internal combustion engines the fundamental theory for two-stroke engines was established by Sadi Carnot, France, 1824, whilst the American Samuel Morey received a patent on April 1, 1826.

 Evaluation of a Spark-Plug-Integrated Fiber-Optic
While the benefits of cylinder pressure information for engine control and monitoring are well recognized, commercial implementations of practical systems have been hampered by one overriding factor: the lack of a cost-effective, reliable, and durable combustion pressure sensor.
Using advanced control algorithms the air-fuel ratio during each cycle is calculated and then controlled by the engine electronic control module.
Optrand sensor was mounted in the head of a single cylinder diesel engine with a reference piezoelectric transducer mounted in the same head in proximity to the optical sensor.

 Components of Internal Combustion Engine   (Site not responding. Last check: 2007-11-05)
The valve-in-head engine has pushrods that extend upward from the cam followers to rocker arms mounted on the cylinder head that contact the valve stems and transmit the motion produced by the cam profile to the valves.
The PCV valve controls the release of crankcase gases and vapors to the intake manifold.
An internal combustion engine, for example, produces power in a succession of bursts that are transmitted by the driveshaft to a flywheel, which absorbs the pulses of energy smoothly into its rotational motion, thereby imparting to the shaft a nearly steady torque.

Their fuel-thrifty internal combustion engines – a 1.0-liter three-cylinder in the Insight and a 1.3-liter four-cylinder in the Civic – provide all the power needed for most driving situations.
The engine will be shut down if the battery module state-of-charge is sufficient, although the engine may idle for a short time before stopping if it’s not clear that a stop is imminent.
The engine is restarted when the accelerator is applied again, a gear is selected with the clutch disengaged on manual transmission vehicles, the brake pedal is released during deceleration, or the battery module’s state-of-charge drops below a threshold level.

 Company Overview | Revetec
The CCE is an internal combustion engine that is lighter, cleaner and more powerful than equivalent conventional engines, and cheaper to manufacture, due to fewer components.
The advantages of Revetec’s engine technology can be applied to most internal and external combustion engines for use in motor vehicles, trucks, buses, motorcycles, pumps and generators, light aircraft engines, diesel and marine engines.
Car manufacturers are seeking an efficient engine to replace their existing engines, as these engines currently do not comply with the tough emission standards in those countries.

 Dry sump   (Site not responding. Last check: 2007-11-05)
A dry sump is a lubricating oil managment method for four-stroke cycle piston internal combustion engines that uses a secondary reservoir for oil, as compared to a conventional wet sump system.
Four-stroke engines are lubricated by oil which is pumped into various bearings and thereafter allowed to drain to the base of the engine.
In a dry sump, the oil still falls to the base of the engine, but rather than being collected into an oil pan, it is pumped into another reservoir.

 Halfbakery: internal combustion steam engine
The idea is this: in an ordinary engine, igniting the fuel in the cylinder causes expansion which moves the piston.
This is done in the hot combustion concept, where the piston top cooling and the cylinder head cooling are eliminated, and the cylinder liner cooling is minimised.This makes it possible to elevate the exhaust gas temperature after the turbocharger by more than 100 degrees Celsius, and significant volumes of steam can be produced.
I am relatively ceratin that the main reason for engine cooling at this point is due not to metalurgic or engineering limitations, but to the limitations of the standard octane gasolines available at the pump.

The engine is driven as close as possible to a selected speed/load combination (24) and the value of a selected engine operating parameter is adjusted to obtain an optimum value at the selected speed/load combination.
One cell (22) in the speed/load grid is displayed in a third visually distinct manner to indicate the engine's current operating position.

In providing a more complete and more controlled combustion, engine efficiency is improved which normally results in increased power output and improved torque.
The extent of the improvement in power output depends on the design, age and condition of engine.
This secondary improvement is thought to occur as combustion chambers and engine operating surfaces are cleaned and with the coating of the internal operating surfaces with tin oxides.
