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. It is used in a wide range of sailboats and motorboats.
The mechanism by which exhaust emissions are controlled depends on the method of injection and the point at which air enters the exhaust system, and has varied during the course of the development of the technology. The first systems injected air very close to the engine, either in the cylinder head's exhaust ports or in the exhaust manifold.
1. manifold; 2. gasket; 3. nut; 4. heat shield; 5. heat shield bolt. Ceramic-coated exhaust manifold on the side of a performance car. In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word manifold comes from the Old English word manigfeald (from the Anglo-Saxon manig [many ...
The valve is closed. The mechanism of diving regulators is the arrangement of components and function of gas pressure regulators used in the systems which supply breathing gases for underwater diving. Both free-flow and demand regulators use mechanical feedback of the downstream pressure to control the opening of a valve which controls gas flow ...
A component used to regulate fluid flow in a hydraulic system, thus controlling the transfer of power between actuators and pumps. Inlet manifold (or "intake manifold") An engine part that supplies the air or fuel/air mixture to the cylinders. Scuba manifold. In a scuba set, connects two or more diving cylinders. Vacuum gas manifold.
In a reciprocating engine, the use of water injection, also called anti-detonation injection or ADI, is used to prevent engine knocking also known as "detonation". [3] Commonly found on large radial engines with pressure carburetors, it is a mixture of water and alcohol injected into the carburetor at high power settings.
The boat has a draft of 3.83 ft (1.17 m) with the standard keel fitted. The boat is fitted with a Japanese Yanmar 2GM20F diesel engine of 18 hp (13 kW). [1] [4] The boat's galley is located on the port side of the cabin and has a stainless steel sink and a two-burner gimballed kerosene stove. The table can swing up and stow when not in use.
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a ...
