The Yanmar 2GM20 is a series of inboard marine diesel engines manufactured by the Japanese company Yanmar Co. Ltd. It is used in a wide range of sailboats and motorboats. The 2GM20 is out of production and has been superseded by the newer Yanmar 3YM20 series.
In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing. It is also affected by the adjustment of the valve mechanism, and particularly by the tappet clearance.
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 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.
Vintage engine testing equipment that can test ignition timing, ignition dwell, manifold vacuum and exhaust emissions. Engine tuning is the adjustment or modification of the internal combustion engine or Engine Control Unit (ECU) to yield optimal performance and increase the engine's power output, economy, or durability. These goals may be ...
2. Invest with a long-term mentality. The rich also have a long-term ownership mentality when it comes to their investments. They’re not thinking about making a great score from a quick trade ...
The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing or variable valve lift, the valve timing is the same for all engine speeds and conditions, therefore compromises are necessary to achieve the desired result in intake and exhaust efficiency . This has been described ...
