What is Exhuast Gas Recirculation (EGR)?

Nitrogen oxide (NOx) is generated during the combustion of a fuel and air mixture. However, if the temperature during combustion is lowered, the emission amount can be reduced. Once such technique for reducing emission is exhuast gas recirculation (EGR). In this technique, the combustion temperature is restricted by recirculating the exhuast gas back to the cylinders to lower the oxygen concentration. These are two EGR systems; external EGR and internal EGR. In external EGR the line of the engine and the supercharger must be equipped with devices such as EGR solenoid valves and coolers, and control must be performed for them. But in internal EGR, these fuctions can be performed by controling the lift of the intake and exhuast valve.

Performance

 This 180 mm long stroke 20 litre class diesel, with big breathing valves for better airflow, the high performance turbo for compactness, and the numerous other performance features deliver power in large amounts over a wide operating range. especially under high load conditions.

Good fuel economy together with lower emissions

The micro size multiple holes in the all new injectors produce and even finer fuel-oil mist and, combiined with the new perfectly matched combustion chambers and new cylinder head shapes, produce even more power. It is power delivered smoothly, due to optimum combustion conditions being maintained across a far wider operating range. It leads directly to the bonus of lower exhuast emissions and lower fuel consumption. The boost compensator dramatically reduces black smoke under hard acceleration.
