DHI has developed completely new six-cylinder K series engine
for heavy-duty commercial vehicle as well as other industrial
equipment. And DHI will produce it in the new kunsan engine
plant.
The main development targets were low emissions, excellent fuel
economy, longer durability and minimum maintenance.
For fulfilling these targets, high-pressure electronic unit
injector system (EUI) with 4 valve and overhead camshaft (OHC),
symmetrically structured cylinder block with very stiffened
cylinder liner and bed plate, decompression engine brake system
were adopted.
During the design stage, CAE technology played very important
role, through detail analysis and optimization. The K series engine
achieved low exhaust gaseous emission level of Euro 3 as well as
good fuel consumption, noise level lower than 96 dB(A), and major
overhaul period longer than 1.5 million km.
