What are the three emission systems found on street motorcycles? What type of emissions does each system address?

What will be an ideal response?


The first emission system is for crankcase emissions. This system reroutes blow by gasses back into the airbox where the hydrocarbons are burned. An air oil separator collects condensed crankcase vapors. The second system is the evaporative emissions system where gasoline vapors from the fuel tank and float bowls are collected in a charcoal canister. The last system addresses exhaust emissions like hydrocarbons and carbon monoxide. In this system filtered air is introduced into the exhaust system via the exhaust port. The fresh air is used to help complete the burning of any unburned fuel in the exhaust gasses. Fuel injected motorcycles may also have a catalytic converter to reduce carbon monoxide, hydrocarbons and oxides of nitrogen.
