Excess pressurized oil from boom cylinder rod side is delivered to arm cylinder bottom side through a regenerative valve to increase flow rate for productive operation. Enhanced Boom Recirculation System In combined operation of boom lower and arm, pressurized oil from boom cylinder bottom side is delivered to boom cylinder rod side, assisted by boom weight, for boom lowering. At the same time, pressure oil from the pump is delivered to the arm cylinder for arm movement. This mechanism allows an increase of speed in combined operation of 15 %. Development Concept of New Engine OHC 4-Valve Engine The new OHC -valve diesel engine is developed and built to comply with the rigorous Emission Regulations enforced in 2006 in U.S. and EU. This new engine contributes to environmental preservation. At the same time it realizes high durability and low fuel consumption by adapting the latest advanced engine technology. Common Rail Type Fuel Injection System Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail. This enables optimum combustion to generate big horsepower, and reduce PM* (diesel plume) and fuel consumption. Cooled EGR** System The cooled EGR system lets part of exhaust gasses mix with intake air for re-combustion to reduce oxygen concentration in the air in the combustion chamber. This design lowers combustion temperature in the cylinder, reducing fuel consumption and NOx while yielding more horsepower. *Particulate Matter **Exhaust Gas Recirculation Fuel Filter Fuel Pump Common Rail Pressure Sensor Common Rail Coolant EGR Cooler Control Unit EGR Control Valve Intake Cylinder Head Fuel Tank Control Unit Injector Exhaust 6 7
