Expanded stroke Combustion,combustion gas expands more fully, which increases effective power output, assures low fuel consumption under strong power. Advanced 4-valve structure, has larger horsepower, more adequate air burning,and low fuel consumption, while it also increases low-speed torque , has good power performance, and high working efficiency. With forced cooling articulated piston, can withstand very high mechanical load and heat load, has good strength. Enhanced cylinder design, low noise and low vibration. The central arrangement of the injector and the symmetrical combustion chamber make the in-cylinder mixture more even and burning more sufficiently.  Advanced design, the power ratio is up to 30.0kW / L, the machine structure is reasonable and has more convenient maintenance.

User Guidelines 1. The operating should not out range of the approved number of people and cargo weight. 2. You should take new engine checking and mileage compulsory maintenance when beyond the running travelled distance. 3. You should be clearly that you can’t modify the structure of the engine. 4. if you need to change the spare parts, make sure that you use original spare parts. After-market parts might damage your engine. 5. The quality of lubricating oil using on mechanical B series engine should not lower than API CF-4/SG standard, the viscosity is 15W-40 or when using in the arctic climate 10W-30 and 5W-20. The quality of lubricating oil using on electronic B & C series engine should not than API CH-4/SJ Performance range, the viscosity is 15W-40 or when using in the arctic climate 10W-30 and 5W-20. 6. Your engine must use antifreeze anti-rusted solution, and should change the liquid timely. DCEC recommend to use composite coolant or 50/50 high quality water mix with composite anti freeze. a. The high quality water should meet all technical requests: concentration of chloride is lower than 40ppm, concentration of sulfate is lower than 100ppm, calcium/magnesium is lower than 170ppm; the prior choice is ionized water, distilled water or softened water. b. Glycol working range between 40-60% is acceptable. c. The concentration of SCA is in the range of 0.3-0.8.
