Doosan Daewoo series of detailed content

I. Overview of Doosan Daewoo series products
 Daewoo engine has a production of low-power engine 40,000 units, 25,000 units in the power engine, high-power engine 12,000 and 8,000 ships with the engine production capacity. Daewoo is striving to develop eco-friendly engines with high power consumption, low fuel consumption and miniaturization based on abundant production experience, latest unmanned automatic production equipment and independent technology development capability. From 2004, Daewoo's diesel engines are in line with the most advanced environmental standards in the world. In the long-term technological development plan, Daewoo's industrial products will meet the environmental requirements of TIER-3 and EURO-Ⅳ.

Second, the Doosan Daewoo series features:
 1. Advanced and reasonable cylinder head design: Danghuo greatly improved the life of the generator cylinder pad; Cylinder cover bolts greatly extend the service life and improve reliability
 2. Wet, interchangeable bushing design with damper ring and oil-cooled pistons to ensure low operating costs and long service life
 3. The use of flexible shock absorber than the rubber shock absorber performance is superior
 4. The supercharger utilizes the energy of the exhaust gas to improve the energy utilization rate, thus improving the output power, reducing the fuel consumption rate, exhausting cleaner, reducing the high frequency noise and prolonging the service life
 5. High-capacity oil pump and efficient oil cooler and all-pass oil filter composed of efficient lubrication system to reduce wear and prolong the engine component life
 The use of integrated structure, beautiful appearance, easy installation, vibration, high work safety. The control panel is placed at the top of the generator set after the anti-vibration measures. Engine, generator using a rigid connection, itself vibration to a minimum, efficient shock absorber absorbs most of the unit vibration. High-strength steel production base of the tank, but also has a vibration-absorbing function
