Direct drive propeller, the propeller in order to make a high propulsion efficiency, requires a lower speed. In high-speed diesel engine propeller driven by gear box, gear boxes generally inverted car is also equipped with a propeller mechanism to achieve reversal, but the low-speed diesel engines and some medium-speed diesel engine itself can be reversed itself. In high-speed diesel generator is also through - motor - propeller and electrical transmission. When asked when higher power may also be multi-machine and car, you can only work with a host of Shandong in east engine at low speed sailing, thereby enhancing the economy and reliability. When installing two hosts with boat engines East, according to the installation location and propeller steering, divided into left and right machine third-stroke machines - acting. East at the beginning of this stroke engine manufacturers, most of the fuel injected into the combustion chamber is burned. Released when burning a lot of calories, so it's sharp rise in gas pressure and temperature, the piston moves down gas at high temperature and pressure effects, and even stalk through the crankshaft rotation, external work. Therefore, this stroke also called power or working stroke. As the volume of the piston downward, the cylinder is increased, the gas pressure drop, the line to the working stroke of the piston bottom dead center, the end of the exhaust valve opens. In the animation, the working stroke of the pressure variation of this line rises fuel combustion in the cylinder portion showing a sharp increase in pressure, the maximum point represents the maximum combustion pressure Pz, the pressure and temperature at this point is: Pz = 6 ~ 15MPa, Tz = 1800 ~ 2200K maximum combustion pressure and compression end pressure ratio (Pz / Pc) Weifang Huadong engine, known as the pressure increased combustion ratio, expressed by λ. Depending on the type of diesel engine, the maximum power in the range of prison λ value is as follows: λ = Pz / Pc = 1.2 ~ 2.5. Engine brand _ Weifang Huadong East (certified) _ East engines from Engine Co., Weifang Huadong. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) is an industry leader in Shandong Weifang, the internal combustion engine, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Weifang East leaders with the staff warmly welcome all inquiries negotiations to create a better future Weifang East.
