Summary of change:
'''This page is about how to control an evaporator canister - sometimes called as charcoal purge canister''' The evaporator canister is ment as a temporary storage for gases from the fuel tank, instead of releasing them to atmosphere. A simple valve controlled by GenBoard releases the gases to the intake given some conditions are met. * low RPM * low MAP * warm engine * closed-loop operation * ... ? Maybe with WBO2 closed loop control the condition becomes very simple. Since we haven't seen much research/feedback on this (anyone want to contribute links or experience?) ... I plan to install a solenoid to suck out the evaporator canister from time to time, using the same condition as for the variable intake with MembersPage/MarcellGal/EngineSwap/AirFeed : 1500..3000 RPM, 80..101kPa MAP. Actually planning to use same ECM output (a FET), but different solenoid (the 2 solenoid connected in parallel electronically). google words: ... pages: ... Fero (or someone else), can you collect info about valve control that I believe was collected before but misplaced? ---- '''See also''' * BoostControl : similar (small solenoid air-) valve is used
