Yanmar was founded in March 1912 in Osaka, Japan, [2] by Magokichi Yamaoka. [3] [4] When the company began in 1912, it manufactured gasoline-powered engines. [5] In 1920 the company began production of a small kerosene engine. [6] In 1933, it launched the world's first practical small diesel engine, the HB model. [5] [7] [8]
A Yanmar 2GM20 marine diesel engine, installed in a sailboat. The center pulley is the crankshaft , the lower left one the seawater pump , the upper right one the alternator . The Yanmar 2GM20 is a series of inboard marine diesel engines manufactured by the Japanese company Yanmar Co. Ltd.
In an external combustion engine, such as a steam engine, the control of the valve timing is by the valve gear. In a typical piston valve arrangement, the timing of the intake and exhaust events for each cylinder are inextricably related as they are governed by the movement of a single piston uncovering two ports.
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.

Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.
