Reliability and durability

• The development of product is carried out with rigorous mechanical engineering development accreditation standards, durability bench test accumulated for 20000 hours.

• Engine block manufactured from alloy cast iron offers higher strength.

• Forged steel crankshaft improves fatigue strength and resistance to wear.

•A cylinder head is respectively bolted to the top of each bank of cylinder for ease of maintenance and repair; Cylinder head bolts are evenly spaced and positioned, which is better able to withstand forces evenly.

• Valve timing mechanism, camshaft is placed in the upper part of cylinder block, short and thick push rod and roller tappet, so as to achieve higher reliability.

Fuel economy

• Four-valve technology increases the flow areas of air by a wide margin, so as to realize better atomization condition and more intense combustion.

• Turbocharged and intercooled & electronic combined pump technology, precise electronic control ensure full combustion.

• Holst turbocharger/lian xin turbocharger, wider fuel economy area.

• Mechanical losses are reduced dramatically more than 15%, and less air pumping losses and consumption.

• Fuel consumption is reduced by 10-15% compared with engines of same power.

Safety and comfortability

• Four-valve technology reduces effectively intake and exhaust noises.

• Rear positioned gear chamber and advanced point-line gear-meshing technology are adopted to lower mechanical noise of transmission system in further.
