The 4-valve cylinder head provides excellent airflow resulting in greater low-speed torque and better transient response. Cross flow design.
Electronic unit injectors (EUI) and engine control unit (ECU)
The EUI fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 2000 bar (29,000 psi). It also controls fuel injection timing and provides precise control for start, duration, and end of injection.
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 (VGT)
Varies exhaust pressure based on load and speed to ensure proper EGR flow
An efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.
