Tank Vent Valve pitanje za firea i stručnjake


Recommended Posts

Evo što kaže opelov manual:

TANK VENTILATION

 

If the fuel in the tank becomes warmer due to outside influence or in passing through the fuel supply system (fuel pump, fuel line, distributor pipe), then vapours form which cannot be released into the atmosphere in a vehicle with catalytic converter.

 

The vapours which form in the tank are released into the atmosphere via the active carbon filter when the engine is not running The petrol vapours are retained by the active carbon and temporarily stored until the next time the engine is operated.

 

In the partial and full load ranges the tank ventilation valve is opened by the control unit. Due to the vacuum in the intake manifold, fresh air induction takes place via the active carbon filter when the engine is running.

 

The temporarily stored fuel vapours are thus expelled.

 

In order to prevent this flushing of the active carbon canister from interfering with the engine running, the tank ventilation valve is only triggered during active oxygen regulation, when the engine temperature is greater than 49.8 °C and when the idling switch is open.

 

Zašto pitam? Zato što isto treba spojiti na VEMS.. :lol:

A koji tu problem imas?

Vrlo jednostavmo za spojiti. Uzmes spremnik sa aktivnim ugljenom (bilo kji auto - ako nemas dodji kod mene ja cu ti ga pokloniti zajedno sa elektroventilom), spojis odusak iz rezervoara na njega , crijevo iz njega na elektroventil s kojim upravlja racunalo motora, i sa elektroventila crijevo na usisnu granu.

Drugo je pitanje kako se rijesava da sistem radi kad je najoptimalniji broj okretaja da to motor "pojede".

Po meni to ne trebas jer to je napravljenp zbog ekologije - ispustanja benzinskih para iz rezervoara u motor, umjesto u atmosferu.Taj "odusak" nema veze sa radom motora, bez obzira na koju elektroniku (stand alone ili serijsku).

Ma nije ekologija nego radi sigurnosti. Te pare su jako zapaljive...

 

Ima ja sve spojeno, samo treba spojiti da VEMS odradi otvaranje...

 

Znači 30% na 30HZ napraviti sa 555? Jer pretpostavljam to VEMS neće raditi...

da s ne555 napravis, imam negde tocnu shemu di su tocni podatci frekvencije i dc-a, dok dodem u ck potrazim. Moze ti to vems raditi, ali po mome je glupo koristiti pwm portove za to.

Ja vozio cca 1godinu bez da sam to spojio i nisam nista negativnog primjetio.
