Purpose, function
The check valve maintain the pressure in the fuel tank at constant pressure.
Construction
The check valve is installed to the side of the charcoal canister.

Mainly consists of valve, umbrella, and spring.

Operation
The valve moves in response to the difference in air pressure between the fuel tank side and the atmospheric side, thereby changing the path of airflow.
When the pressure in the fuel tank becomes negative due to fuel consumption or other factors, the path opens, drawing atmospheric air into the fuel tank.

Outline
Based on the control of the HO2S heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.

Characteristics of Ultra High-Tensile Steel Plates
Ultra high-tensile steel plates have enhanced tensile strength compared to
previous high-tensile steel plates.
Because the strength is maintained even though the plates are thin-walled,
the ultra high-tensile steel plates ar ...
