High-strength alloy cast iron engine body, forging crankshaft, and connecting rod employing the cracking technology are adopted, which ensure high reliability after years of full verification by market.
Advanced and mature electronically-control common rail (BOSCH) and high-efficient turbocharged intercooled technologies are equipped with, which ensure precise control of fuel-injection quantity and sufficient air intake; and the full combustion, low fuel consumption and less emission of diesel engine under different load conditions are ensured.
The internally-cooled oil channel is adopted for piston, which effectively reduces piston temperature and ensures the long service life.
In terms of product performance and emission, compliance with the requirements of G3 performance in GB2820 and the requirements of China III (T3) in GB 20891, respectively.
