Komatsu’s new diesel engine is designed to meet Tier-4 emissions regulations, reducing exhaust gas particulate matter by more than 90 percent and oxides of nitrogen by more than 45 percent. The new technology includes newly designed variable geometry turbocharger and diesel particulate filter; heavy-duty high-pressure common rail fuel injection system and a redesigned combustion chamber at the top of the piston.
