Emission Control System (ECS)

EMISSION CONTROL SYSTEM (ECS)

The tractor engine is equipped with the following emission control systems

1.Positive Crankcase Ventilation (PCV) System

2.Exhaust Gas Recirculation (EGR) System

3.Diesel Oxidation Catalyst (DOC)

4.Under-Hood Muffler (UHM)

The schematic layout of the ECS is as follows :

Positive Crankcase Ventilation (PCV) System

The tractor engine is equipped with a positive crankcase ventilation system. This separates the oil efficiently from the engine blow-by gases through a high performance media, maintains the crankcase pressure within acceptable safe limits.

Always carry out the maintenance work only when the engine is switched off and parked properly. Never start the engine without an oil separator and/or cover.

Exhaust Gas Recirculation (EGR) System

The tractor engine is equipped with an electrically controlled EGR system. This system comprises the following units,

•EEGR Valve

•EEGR Cooler

NOTE:

Check the EGR system regularly to ensure that its electrical, pipe and hose connections are proper and damage free and free from external soiling and leakages.

Periodic inspection and tightening of mounting hardware is typically appropriate.

A faulty EGR system is noticeable by,

1.Black smoke

2.Reduction in engine power output

3.Abnormal vehicle shakes

4.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.
