L-4 TEST

An engine test in a six-cylinder spark-ignition Chevrolet engine to evaluate crankcase oil oxidation stability, bearing corrosion, and engine deposits.

L-3 TEST

An engine test in a four-cylinder Caterpillar engine to determine stability of crankcase oil at high temperatures and under severe operating conditions.

OIL RECLAIMING

  1. A process in which oil is passed through a filter as it comes from equipment and then returned for reuse, in the same manner that crank case oil is cleaned by an engine filter. 2. A method in which solids are removed from oil by treatment in settling tanks.

DEPOSITS

Oil-insoluble materials that result from oxidation and decomposition of lube oil and contamination from external sources and engine blow-by. These can settle out on machine or engine parts. Examples are sludge, varnish, lacquer and carbon.

DIPSTICK

A graduated rod which measures depth when dipped in a liquid, used, for example, to measure the oil in an automobile engine crankcase.

API ENGINE SERVICE CATEGORY

Gasoline and diesel engine oil quality levels established jointly by API, SAE, and ASTM, and sometimes called SAE or API/SAE categories; formerly called API Engine Service Classifications.

RATED SPEED

The crankshaft revolutions per minute at which the rated power occurs as specified on the nameplate and in the technical file of the engine.

BIG END BEARING

A bearing at the larger (crankshaft) end of a connecting rod in an engine.
The bearings are made of cast steel and each consist of an upper and lower part secured to the connecting rod by means of fitting bolts, the nuts of which are secured. Compression shims are provided between the bottom end bearing and the palm of the connecting rod.
The bearings have white metal bearing surfaces provided with lubrication grooves for the necessary supply of lubricating and cooling oil. Shims of different thickness are inserted between the shells to enable adjustment of the bearing clearances (approx. 0.20-0.30mm).

DIESELING

  1. Explosions of mixtures of air and lubricating oil in the compression chambers or in other parts of the air system of a compressor. 2. Continuation of running by a gasoline spark-ignition engine after the ignition is turned off. Also known as run-on.

BYPASS TYPE LUBRICATING OIL SYSTEM

In an auxiliary diesel engine bypass type lubricating oil system, the main lube oil pump forces some of the oil used by the engine through a filter.
