n: on a diesel engine with a distributor-type fuel injection system, the sequence in which the distributor sends fuel to each engine cylinder.

n: a device containing an angle indicator, a timing element, and a replaceable chart that is used to measure the direction and the degree of deviation as a hole is being drilled. The timing element goes off when the tool has come to rest just above the drill bit and descends on the sharply pointed angle indicator, which then punches a hole in the chart. The chart rotates 180., and a second hole is punched to verify a correct reading of the resting angle of the tool.

n: a kind of mechanical inclinometer

n: a timing unit for drilling ,namely 30 days is a drill-month

n: the injection of fuel at precisely the right moment in an engines operating cycle. Proper injection timing is vital, because it gives maximum power from the fuel, good fuel economy, and clean combustion.

n: the relationship of all moving parts in an engine. Each part depends on another, so all parts must operate in the right relation with each other as the engine turns.

n: see timing gear train.

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.

n: The timing watch be used on the inclinometer,which be used to control the exposure time
of photographic film.
