Diesel engine PowerTech PSS

4-cylinder

6.8L Industrial Diesel Engine • 6.8L PowerTech™ PVX • 138 - 187 kW (185 - 250 hp) Features ENGINE PERFORMANCE • Multiple rated speeds to further reduce noise and improve fuel economy • Higher level of peak torque • Optional power bulge COOLED EXHAUST GAS RECIRCULATION (EGR) • EGR cools and mixes measured amounts of cooled exhaust gas with incoming fresh air to lower peak combustion temperatures, thereby reducing NOx. VARIABLE GEOMETRY TURBOCHARGER • Varies exhaust pressure based on load and speed to ensure proper EGR flow. The combination of the cooled EGR and VGT provide low-speed torque, quicker transient response, higher-peak torque, and world-class fuel economy. HIGH-PRESSURE COMMON-RAIL (HPCR) AND ENGINE CONTROL UNIT (ECU) • The HPCR fuel system provides variable common-rail pressure and higher injection pressures up to 1,975 bar (29,000 psi).One ECU controls the exhaust filter, as well as fuel system and provides precise control for the start, duration, and end of injection. 4-VALVE CYLINDER HEAD • The 4-valve cylinder head provides excellent airflow resulting in greater low-speed torque and better transient response time by utilizing a cross-flow design.
