Exhaust Emission Control Information
In order to protect our common environment, Zhejiang Qianjiang Motorcycle Co., Ltd. has introduced
crankcase blow-by gas filtration system (1) and exhaust emission control system (2) which conform to the
applicable regulations of the US Environmental Protection Agency and California Air Resources Board, and
equipped the motorcycles sold in California only with fuel vapor recovery system (3) which conform to the
applicable regulations of California Air Resources Board.
1. Crankcase blow-by gas filtration system
This system is used to prevent crankcase gas from being discharged to the atmosphere. The crankcase gas is
forced into the intake side of the engine after passing oil separator. When the engine is working, the gas is fed into
the combustion chamber and then will combust with the fuel and air from the fuel injection system.
2. Exhaust emission control system
This system can reduce the amount of pollutants discharged to the atmosphere in the exhaust generated by
this motorcycle. The fuel injection system, ignition system and exhaust system of this motorcycle are carefully
designed and assembled to ensure efficient engine operation and low emissions of pollutants.
The exhaust system of this motorcycle includes a catalytic converter system.
3. Fuel vapor recovery system
The fuel vapor in the fuel injection system is not discharged to the atmosphere but is forced into the working
engine and will burn out. If the engine is not started, the vapor will be stored in the canister. If it is a fluid fuel, it
will be sucked into oil separator, and then return to fuel tank.
Atmospheric Protection Act is a federal law that deals with motor vehicle pollution and includes provisions
commonly known as “Modification Regulations of Air Pollution Control Act”.
“203(a) No one may do or instigate others to do the following:
(3) (A) Before the final buyer purchases or receives the motorcycle or motorcycle engine, no person shall
dismantle or damage any part mounted on the motorcycle or motorcycle engine according to the regulations of the
manual; the manufacturer or dealer shall not intentionally remove or damage any part after the sale or delivery of
any motorcycle or motorcycle engine to the final purchaser.
(3) (B) After the sale or delivery of any motorcycle or motorcycle engine to the final purchaser, any person
who engages in the repair, maintenance, sale, lease or transaction of motorcycle or motorcycle engine or the
operation of motorcade shall not remove damage any part mounted on the motorcycle or motorcycle engine…”
Re
mark
It is generally accepted that “the removal or damage of any part” has the following meaning:
1. The temporary removal of any part for maintenance or temporary failure to operate the part does not belong to
“modification”.
2. The following cases belong to “modification”:
a. Incorrectly adjust vehicle components, so that the exhaust emissions exceed the emission standards.
b. Use replacement part or accessory, thus affecting the performance or durability of motorcycle.
c. Add part or accessory, thus making motorcycle out of the standard.
d. Permanently remove, disassemble or damage any part of exhaust emission control system.
It is recommended that all dealers comply with the above regulations of federal law and any violators will
be subject to civil fines.
