Instead, two pistons face each other and the space between them serves as the combustion chamber.

Tuesday's first launch attempt was aborted because of low pressure in the combustion chamber.
Some are rotary, with as many as four small geared elliptical rotors creating and then foreclosing combustion chamber volume.
This fan is used to blow up to 90% of the air around the outside of the compressor and combustion chamber.
The Hemi, made by DaimlerChrysler AG's Chrysler Group, is the nickname for a series of engines known for their dome-shape--or hemispherical--combustion chamber.
The first attempt to launch the rocket was halted Saturday when a flight computer detected high pressure in an engine combustion chamber.
It has an insulated combustion chamber as opposed to an open fire.
The name derives from the hemispherical shape of the combustion chamber.
The difference between turbocharging and supercharging is simple: a turbocharger boosts engine air pressure by using exhaust gas to power a turbine that pushes more air into the combustion chamber.

Cars like the Buick Encore, Fiat 500 and Lincoln MKZ, meanwhile, improve mileage through direct fuel injection, which injects gas directly into the combustion chamber in extremely precise amounts.

J. customizer William Dodge, who created one bike for Herold using a 1947 Harley flathead engine and another using a 1966 shovelhead engine (that is, with a domed combustion chamber).
The EPA pulled off the feat by sharply increasing the amount of oxygen-poor exhaust that is recirculated into the combustion chamber and increasing the pressure of the fuel being forced into the cylinder.
It works by forcing fuel directly into the combustion chamber of each cylinder to mix air and gas simultaneously at the point of combustion, rather than mixing air and gas in a separate chamber like more conventional engines.
