Detailed Product Description: | The fourth stroke - exhaust. The function of the exhaust stroke of the exhaust gas is discharged to the expanded retail Weifang Huadong ship machines to fill the fresh air, to prepare for the next cycle of intake. When the working stroke of the piston is moved to the vicinity of the bottom dead center, the exhaust valve opened, the piston driven by the crankshaft and connecting rod, the lower dead point up dead center, and the exhaust gas is discharged outside the cylinder. Due to the existence of the resistance the exhaust system, so when the exhaust stroke starts, the gas pressure inside the cylinder 0.025-0.035MPa higher than the atmospheric pressure applied, the temperature Tb = 1000 ~ 1200K. In order to reduce the resistance of the piston movement of the exhaust, the exhaust valve before your next stop on the open. Exhaust valve opened Shandong East China sales, a certain pressure of gas immediately rushed outside the cylinder, the cylinder pressure decreased rapidly, so that when the piston moves upward, the exhaust gas inside the cylinder piston upward rely discharged. To take advantage of the inertia of the exhaust gas flow of the exhaust gas discharge time was clean, exhaust valve was closed after top dead center. Shandong in east China ship machine animation partner, the exhaust stroke curve indicates the exhaust process, the gas pressure cylinder is almost constant, but the number is slightly higher than the atmospheric pressure. The end of the exhaust stroke pressure Pr of about 0.105 ~ 0.115MPa, Pr residual gas temperature of about 850 ~ 960K. 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 in their main and auxiliary. Host for the ship's propulsion, auxiliary used to drive generators, air compressors or pumps. Weifang Huadong ship machine service | EAST boat machine | 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.
