The first stroke - breathing, its task is to make full of fresh air in the cylinder. When the intake stroke marine engines beginning Shandong East China cooperation, the piston is at top dead center of the combustion chamber in the cylinder also left some of the exhaust gas. When the crankshaft rotates the elbow, so that the piston rod dead point is moved downward from the top dead center, at the same time, the use of the crankshaft drive mechanism associated intake valve opens. With the downward movement of the piston, the volume of the piston within the cylinder increases above: causing the air pressure within the cylinder is lower than the pressure within the intake pipe, and therefore the outside air is continuously charged into the cylinder. Case intake process gas pressure within the cylinder as the cylinder volume changes as shown in the animation. Figure ordinate represents the gas pressure P, the horizontal axis represents cylinder volume Vh (or piston red S), the graph is called dynamometer. Pressure curve in the figure represents diesel engine, the variation of the gas pressure inside the cylinder. We can see that the intake starts from the soil, due to the presence of residual gas, so slightly higher than the atmospheric pressure P0. In the intake process flow resistance due to the generation of Weifang Huadong ship machine wholesalers intake manifold and air intake valve through, the gas pressure of the intake stroke lower than the atmospheric pressure, the value of 0.085 ~ 0.095MPa, the entire intake process the gas pressure inside the cylinder remained largely unchanged. When the piston downward movement close to the bottom dead center, burst into the air cylinder still has a very high speed, a lot of inertia, in order to increase the use of air inflatable amount of inertia, the intake valve of the piston through the lower dead point only after close . At a time when the piston up Shandong East China Ship Suppliers, but due to the inertia of the East China Weifang airflow ship machine, gas cylinder still charge people. Flywheel generator housing front cover of the diesel engine using the axial positioning shoulder formed integrally directly connected, and the cylindrical rotating flywheel by a flexible coupling direct drive generator, which are secured together by a screw connection mode, so that the two It is connected into a steel body, to ensure the concentricity of the range diesel engine crankshaft and the generator rotor prescribed.
