n: a structure erected to contain petroleum or a petroleum-fed fire in case a storage vessel ruptures or collapses. Usually a dike is built around the petroleum storage tank and a steel or stone wall is put up between the prime movers and the oil pumps in a pipeline pumping station.

n: on an engine, a device used to remove foreign particles from the engines lubricating oil. The engines oil pump forces the oil through one or more oil filters. Special elements in the filter trap the particles and prevent them from circulating through the engine and possibly damaging it. Many types of filter are available.

n: on an engine, a steel trough-like attachment fitted to the bottom of the engines crankcase. The engines oil pump picks up oil from the pan and circulates it through the engine.

n: a special pump, usually of the gear type, that moves oil through an engine. The pumps intermeshing gears rotate to build pressure and circulate the oil.

n: a wire-mesh screen, usually located at the point where the oil pump picks up oil from an engines oil pan. The screen traps large foreign particles that may not have settled to the bottom of the pan. Compare oil filter.

n: a structure erected to contain petroleum or a petroleum-fed fire in case a storage vessel ruptures or collapses. Usually a dike is built around the petroleum storage tank and a steel or stone wall is put up between the prime movers and the oil pumps in a pipeline pumping station. Also called fire wall.

n: a set of gears in an engine, driven by the crankshaft, set to drive the equipment necessary for the engines operation. Engine equipment driven by the timing gears includes the oil pump, intake and exhaust valve mechanisms, fuel injectors, and magnetos.
