EMISSION CONTROL
All the TVS vehicles are tested in the factory for
optimum fuel efficiency and CO levels. If the vehicle
needs any adjustments, please consult nearest
TVS Motor Company Authorised Main Dealer or
Authorised Dealer.
While adequate care is exercised at the factory to
ensure that the emissions are within the limits, it is
essential for the owner to always maintain the scooter
in good condition by getting it periodically checked
and serviced by TVS Motor Company Authorised
Main Dealer / Authorised Dealer so that the emission
and fuel consumption levels are maintained as per
norms.
Crankcase emission control system
The engine of new TVS Jupiter is equipped with a
closed crankcase system to prevent discharging
crankcase emissions into the atmosphere. Blow-by
gas is returned to the combustion chamber through
the air cleaner and the fuel system.
Evaporative Emission Control System
TVS Jupiter is equipped with an evaporative emission
control system which consists of a canister and
associated piping. This system prevents the escape
of fuel vapors from the fuel tank.
