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.
