Emission Control System (ECS)

b.Exhaust Gas Recirculation (EGR) System

The EGR system employed is a high pressure loop EGR with a cooler in the circuit, to maintain optimized gas temperatures. For Satisfactory operation of EGR System, Care must to take to ensure leak proof connections EGR system works as follows:

EGR system is designed to send measured quantity of exhaust gas into the engine cylinder under various engine operating conditions. This is achieved by opening the EGR valve to a pre-determined level through ECU. EGR valve operates and controlled by electrical signals from ECU. Exhaust gas is made to pass through EGR cooler which is cooled by Engine water of the cooling system to reduce the gas temperature. EGR gas enters the intake system through EGR mixer pipe fitted in the engine intake system. Periodic inspection and tightening of mounting hardware is typically appropriate.

A faulty EGR system is noticeable by, a.Black smoke b.Reduction in engine power output c.Abnormal vehicle shakes d.Emission control System indicator blinks continuously past two minutes.

If you observe the above conditions in your tractor, please immediately consult a Mahindra authorized dealer/service centre and get the problem rectified.

NOTE: Check the EGR system regularly to ensure that it’s electrical, pipe and hose connections are proper and damage free and free from external soiling and leakages.
