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: (1) in designing or ordering hoisting (lifting) equipment, the maximum weight that the equipment will be able to safely lift. (2) on diesel electric rigs, the maximum amount of electric power that the generators will have to produce to adequately power the rig.

a material that can quickly destabilize foam in a production fluid treating facility. Commonly needed after treatment with foamers, diesel, some polymers, some acids and gasified fluids.

n: the equipment for transporting and using coiled tubing, including a reel for the coiled tubing, an injector head to push the tubing down the well, a wellhead blowout preventer stack, a power source (usually a diesel engine and hydraulic pumps),and a control console. A unique feature of the unit is that it allows continuous circulation while it is being lowered into the hole. A coiled tubing unit is usually mounted on a trailer or skid.

n: the line in a certain type of fuel-injection system for a diesel engine that keeps fuel at a given pressure and feeds it through feed lines to each fuel injector.

n: a fuel-injection system on a diesel engine in which one line, or rail, holds fuel at a certain pressure and feed lines run from it to each fuel injector.

n: (Cl) an ignition method used in diesel engines by which the air in the cylinder is compressed to such a degree by the piston that ignition occurs upon the injection of fuel. About a I-pound (7- kilopascal) rise in pressure causes a ZO-F (] O-C) increase in temperature.

n: the pounds-persquare- inch (kilopascal) increase in pressure at the end of the compression stroke in an engine, about 500 pounds per square inch (3,500 kilopascals) in a diesel engine.

a diesel engine;an engine in which the air and fuel are ignited by the heat produced on the compression stroke.

n: on a diesel engine, the rackand- pinion gear that allows the engine operator to regulate the amount of fuel the injector forces into the combustion chamber of the engine. See rack-and-pinion gear. control valve n: a valve designed to regulate the flow or pressure of a fluid.
