n: the network of devices by which air is taken into an engine for combustion in the cylinders.

n: 1.the injection of air into a reservoir in a pressure maintenance or an in situ combustion project. 2. the injection of fuel into the combustion chamber of a diesel engine by means of a jet of compressed air.

n: a substance, such as tetraethyl lead or other compounds, added to the fuel of an internal-combustion engine to prevent detonation of the fuel. Antiknock compounds effectively raise the octane rating of a fuel so that it burns properly in the combustion chamber of an engine. See octane rating, tetraethyl lead.

n: the percentage of gases that escape past the piston rings from the combustion chamber into the crankcase of an engine.

the maximum BTU’s that can be released from a burner while burning with a stable flame and satisfactory combustion.

n: an eccentrically shaped disk, mounted on a camshaft, that varies in distance from its centre to various points on its circumference. As the camshaft is rotated, a set amount of motion is imparted to a follower riding on the surface of the cam. In the intenal-combustion engine, cams are used to operate the intake and exhaust valves.

n: very fine particles of almost pure amorphous carbon, usually produced from gaseous or liquid hydrocarbons by thermal decomposition or by controlled combustion with a restricted air supply. It is used in the manufacture of carbon paper, tires, cosmetics, and so on.

n: a colourless, odourless gaseous compound of carbon and oxygen, A product of combustion and a filler for fire extinguishers, this heavier-than-air gas can collect in low-lying areas, where it may displace oxygen and present the hazard of anoxia.

a colorless gas. Corrosive when occurring with water. An acid gas. The most common cause of corrosion in the oil industry.

n: a colourless, odourless gaseous compound of carbon and oxygen, CO. A product of incomplete combustion, it is extremely poisonous to breathe.

n: the device in a spark-ignition internal-combustion engine in which fuel and air are mixed in controlled quantities and proportions.
