 If periodic maintenance is not done in our franchisers or service centers, we will not be responsible for

possible case of being canceled. Please do necessary checks at all times to ensure optimal functions of the

vehicle.

Note: ① the air filters on vehicles running on gravel pavements or severely polluted environment need to be

cleaned more frequently, so as to lengthen their service life.

② better maintenance should be given to vehicles that are constantly used or frequently running at high

speeds.

15.3 Mechanical Functions of Emission Control System

Profile

The emission solution is based on the use of the four stroke single cylinder engine and the carburetor, air inhaling

device, high standards of emission control and use of charcoal canister for emission evaporation.

※ Improvements in the engine

Exhaust and combustion are improved by improving the spark plug, spherical combustion chamber, compression

ratio, ignition time and exhaust system in the engine.

※ Air inhaling device

Air is led into the exhaust pipe to compose the CO and HC that are not completely burned into harmless emission.
