hydraulic motor engine are mainly of two types

as a majority of you must know, outboard motors are mainly of two types, i.e., 2-stroke and 4-stroke.our company is professional pg电子下载-pg电子游戏,piston motor,hydraulic winch,gearbox,hydraulic steering unit supplier providing customers from domestic zhongyiyepk and overseas the best and reliable hydraulic products.welcome to visit our website. each of these types has its own advantages and disadvantages. however, due to rising pollution concerns, 2-stroke outboard motor engines are now being replaced by the 4-stroke ones. even though the purpose of both of these types of motors are same, i.e. to propel the boat, still there is a vast different in their mechanism.

the 4-stroke engines are much quite and smooth then the 2-stroke ones. they give far more comfortable and pleasurable ride. with better fuel efficiency that produce less smoke and pollution. the reliability of 4-stroke outboard engines is also high as compared to the 2-stroke ones. these engines are better suited for bigger boats. there are some waters which require the use of 4-stroke engines, i.e. a 2-stroke engine will not be able to propel the boat, and thus in this case you have no other option then to go for the 4-stroke engines.

there are some negative sides of a 4-stroke engine like complex design, difficulty in repairing, expensive etc. but still with technology being improved these drawbacks will surely become a thing of past soon.

4-stroke outboard motors consist of an engine block which is made of machined still and on its centre there is a hollow cylinder. this cylinder is critical to the functionality of the engines. there are some other parts attached to the engine block.

the piston is this engine is a can-shaped part designed so as to fit in the cylinder precisely. the rings that are there on the piston are to fit tightly against the walls of the cylinder. in the engine block, there is a crankshaft at the base. in order for the motor to operate, the piston should be connected to the crankshaft. the crankshaft of the engine is akin to the crank arms. in fact, it functions more or less in the same way.

due to internal combustion the piston is pushed down with force. carburetor is another important component of 4-stroke engines. carburetor consists of butterfly valve for air and also needle valves which are there for fuel. both these components work together to provide a proper and perfect level of air and fuel into the cylinder.

valves play an important role in making this system work. the valves in the 4-stroke outboard motor engine are mainly of two types and that is exhaust and intake. in the intake valve, when it opens it allows the air-fuel picture to enter in to the cylinder. whereas the exhaust valve when opens, it allow the burnt fuel-air mixture to exit the cylinder. all this happens during the course of 4-strokes.
