Doosan Infracore has developed three kinds of EURO-4 heavy duty commercial vehicle diesel engines on its own. The main development targets were low emissions, excellent fuel economy, high performance and longer endurance reliability. For fulfilling these targets, Selective Catalytic Reduction(SCR) system, high-pressure common rail injection system with 4 valves, high strength structured cylinder block and cylinder head and new materials for piston and bearing were adopted. During the design stage, CAE technology played very important role through detail analysis and optimization. After the design stage, durability evaluation for each part confirmed the results again through part reliability test.
