Emission Control System (ECS System)
Purpose of ECS system is to keep Emission under control.
ECS system is designed to send appropriate quantity of
exhaust gas into the engine cylinder under various engine
operating conditions.
a. Potentiometer on Throttle gives signal to (Electronic
Control Unit) ECU about position of throttle.
b. Alternator gives signal about the Engine r.p.m.
c. ECU analyses the LOAD on Engine based on inputs for
Throttle Position Vs Engine rpm. It gives appropriate
signal to MODULATOR.
d. MODULATOR then allows controlled vacuum to operate
EGR valve.
Thus appropriate quantity of exhaust gas is
recirculated into the engine cylinder under various
engine operation conditions.
The Emission Control System Indicator will glow
continuously indicating presence of fault in ECS.
The tractor needs attention by Mahindra
Authorised Dealer immediately.
