Brief Introduction of VMAN Diesel Engine

About VMAN

Sino-US joint venture – Shanghai Youngfor Power Co.,Ltd is a specialized diesel engines manufacturers in design, R&D, manufacture and sales, located in Urban industrial Park, Baoshan district, Shanghai. They take vigorous position in design, purchase, process, production site and quality, equipment. Their products run domestic and international standard, sales network cover the entire country and the world.

VMAN products are high power electronic engines whose displacements are of 7L to 30L and powers range from 84KW to 1500KW.

Manufacture Technology

Sino-US joint venture – Shanghai YOUNFOR has fully advanced manufacture process and quality management system. They are well-equipped and experienced in modern production management. They take vigorous position in parts assembly and debug: to prevent the leak of gas, water and oil, they inspect all the engines with leak test; to guarantee the tightening quality, they use ESTIC technology (Japanese Nut runner machine) on all key bolts. Each engine will be debugged before goes to the market. With the use of advanced inspection instruction, all the engines shall meet the technical standards during on-site trials; they also use auto-delivery, rotary carriers, cylinder press fitting and front-rear oil seal press fitting, etc. As advanced methods to further control production and quality, they have also been awarded quality management system TS16949 certification.

R&D Team

Having advanced test methods and practical experience, they well established and strong R&D team is gradually absorbing the introduced drawings and materializing localization with Doosan’s technology back up to make PUAN a leading manufacturer in world engine field.

Introduction of VMAN D Series Diesel Engine

D Series diesel engine imports advanced idea and technology of design, production and management from Europe and the United States. Engine is V-type and gets the technical feature of low compression ratio and body structure reinforcing, which makes the engine much more reliable, powerful, low noise. The engine is easy maintenance, installed simply and can hardly get fault. The engine can always be used at the harsh climatic conditional regions of heat, cold and arid, consequently all these features make it the ideal power of generator, marine engine, auxiliary engine and various engineering machinery.

D Series diesel engine gets optimization of structural design by doing 3D modelling and having a finite element strength analysis, which makes diesel engine get power a great improvement and more than 100kg lighter than other engine of the same power level.

Management system of the engine is electronic speed control loop, making a great steady state control and bettering fuel system matching design. Also, the fuel consumption indicators are the international advanced level.

Cylinder Head

Structure design features of one cylinder head each cylinder, cylinder head bolt uniform distribution

Advantages: Convenient maintenance, forcing uniform of cylinder head bolt, excellent sealing, high reliability.

Piston

Cooling oil duct design, three piston rings structure

Advantages: Low piston temperature, low fuel consumption, high reliability of piston.

Camshaft

Single camshaft design, high shape alloy steel material

Advantages: High stiffness of camshaft, body design to facilitate, strengthening cylinder slipper stiffness.

Turbocharger

Dual turbocharger & Dual air filter design

Advantages: Intake air volume increased, higher compression ratio, handsome outline

Connecting Rod

Oblique incision structure

Advantages: Reduce the noise, improve the service life.
