  Internal combustion engine - Wikipedia, the free encyclopedia
The internal combustion engine is a heat engine in which the burning of a fuel occurs in a confined space called a combustion chamber.
Internal combustion engines can be classified by their configuration which affects their physical size and smoothness (with smoother engines producing less vibration).
Generally internal combustion engines, particularly reciprocating internal combustion engines, produce moderately high pollution levels, due to incomplete combustion of carbonaceous fuel, leading to carbon monoxide and some soot along with oxides of nitrogen and sulfur and some unburnt hydrocarbons depending on the operating conditions and the fuel/air ratio.

 NationMaster - Encyclopedia: Internal combustion engine
Combustion or burning is a complex sequence of chemical reactions between a fuel and an oxidant accompanied by the production of heat or both heat and light in the form of either a glow or flames.
The hot bulb engine is a type of internal combustion engine; more specifically, it is a compression ignition engine, in which the fuel is ignited by being suddenly exposed to the high temperature and pressure of a compressed gas, rather than by a separate source of ignition, such as a...
The Diesel cycle is the combustion process of a type of internal combustion engine, in which the burning of the fuel is triggered by the heat generated in first compressing air in the piston cavity, into which is then injected the fuel - as opposed to it being ignited by a...

 How does an Internal Combustion Engine Work?   (Site not responding. Last check: 2007-10-31)
In an internal combustion engine, a fuel, such as gasoline, fills a chamber and then is ignited by a spark plug, causing a small explosion which generates work.
The internal combustion engine is distinct from external combustion engines (such as steam engines), in that the energy generated from the combustion of fuel is efficiently contained within a cylinder.
Internal combustion engines took some time to perfect because the cylinder must be able to withstand the wear and tear of many thousands of explosions over the course of its operating lifetime.

A V engine is a common configuration for an internal combustion engine in which the pistons are aligned so that, if viewed along the line of the crankshaft, they appear to be in a V. Usually, two opposing pistons share one crank on the crankshaft.

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.
As the piston reaches the bottom, the exhaust valve opens, allowing the piston to force the combustion products—mainly carbon dioxide, carbon monoxide, nitrogen oxides, and unburned hydrocarbons—out of the cylinder during the upward exhaust stroke.

 Internal combustion engine   (Site not responding. Last check: 2007-10-31)
A piston internal combustion engine works by burning hydrocarbon or hydrogen fuel that presses on a piston; and a jet engine works as the hot combustion products press on the interior parts of the nozzle and combustion chamber, directly accelerating the engine forwards.
Jet engines, most rockets and many gas turbines are classed as internal combustion engines, but the term "internal combustion engine" is often loosely used to refer specifically to a piston internal combustion engine in which combustion is intermittent and the products act on reciprocating machinery, the most common subtype of this kind of engine.
In the broadest sense of the term, the internal combustion engine can be said to have been invented in China, with the invention of fireworks during the Song dynasty (some sources put the invention a thousand years earlier still).

 BBC - Radio 4 You and Yours - Triumph of Technology: Internal Combustion Engine
An internal combustion engine is any engine that burns fuel inside the engine - cars, motorbikes, and many types of generator all make use of the internal combustion engine.
The combustion of fuel in a confined space produces gases that are then directly put to work by the engine.
The principle of the internal combustion engine was technically established by the advent of fireworks in the Chinese Song dynasty, but it was in 1826 that the American Samuel Morey received a patent for his reciprocating internal combustion engine.

Too late and the piston is already going down by the time combustion occurs, so you lose power.
As the engine turns faster, and the burn rate of the fuel is the same, the spark must occur sooner.
You want timing to produce maximum combustion pressure at about 20 degrees after TDC In a SI engine advancing will cause slightly more power but will cause detonation and difficult cranking of engine and also pinging under load which should reduce with use of a higher octane gasoline.
