The fuel in the combustion chamber to ignite EAST ship machines to produce high temperature and high pressure gas. In the gas piston driven by the downward movement of the point of Weifang Huadong boat engine service external work only. Piston down until the vent open (in this case in crank position, the gas expansion work at this end, a large number of in-cylinder exhaust gas on its own high-pressure free, people from the exhaust port to the exhaust pipe when the pressure drop in the cylinder when to close the scavenging pressure (typically scavenge the scavenging pressure of 012, the piston down the scavenging port 3 open (in this case point 4 of the crank position, the scavenging air into the cylinder, while the exhaust gas through the exhaust cylinder expelled from the cylinder inlet piston moves to point Shandong East China Marine Engine Partner lower dead end of the stroke marine engine supplier Shandong East China, but the scavenging process continues until the next stroke of the exhaust port is closed (in this case in crank position . Until the third 3.4 342 Figure II-stroke marine diesel engine repair diesel engine Schematic scavenging and compression stroke: the piston moves upward from the bottom dead center, the piston scavenging port before covering by scavenging pump supply store in scavenging box air in through the scavenging port into the cylinder, the cylinder residual exhaust gases are air into the cylinder through the exhaust port sweep of the cylinder. marine diesel engines are the main driving force of civilian ships, warships and conventional submarines (see Marine Power Plant) . marine diesel engines in the ship can be divided according to their host for the main and auxiliary propulsion of ships, auxiliary used to drive a generator, an air compressor or pump in east ship machine vendors |.. East China Marine Engine | Weifang Huadong by Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) strong, credible, in Shandong Weifang engine industry has accumulated a large number of loyal customers and the company continues to better work attitude.
