• Low fuel consumption: The DENSO high pressure common rail fuel system, whose market population exceeds 10 million units, features an injection pressure high up to 1,800 bar, resulting in good fuel atomization, complete in-cylinder combustion and an average fuel consumption drop of more than 5%. • Excellent power output: The low-speed power performance is about 10% higher than that of B series on average, ensuring high power, fast start and good gradeability even under full load. • Low fault rate: The integrated design of cylinder block and water pump, oil pump housing, water inlet/outlet tube, thermostat seat, etc. reduces the amount of components by 25% compared with engines of same type, which reduces the probability of leaking, and resulting in high vehicle availability, and much lower fault rate and maintenance cost.
