Patent
Air/fuel ratio control with adaptive learning of purged fuel vapors
TL;DR: In this paper, a proportional plus integral feedback controller coupled to a two-state exhaust gas oxygen sensor is used to provide an air/fuel ratio indication and a measurement of inducted air flow.
Patent
Evaporative control system for a multicylinder internal combustion engine
TL;DR: In this article, the authors present a system for controlling the fluctuation in an air-fuel ratio in a multicylinder internal combustion engine when the driving period of a purge control valve is substantially synchronized with an engine cycle, thereby better purifying exhaust gas and preventing lean misfires.
Patent
Arrangement for monitoring a system for collecting fuel vapours and taking them to an internal combustion engine
TL;DR: In this paper, an arrangement for monitoring a system for collecting fuel vapours and taking them to an internal combustion engine in a motor vehicle, with at least one fuel vapour adsorbing container (18) which is connected to the fuel tank via a de-aerating line (16) and to the inlet pipe (24) of the internal combustion engines via a regenerating line, is fitted with a valve (32) which briefly blocks the ventilating line when the engine is running, whereby system changes are detected to assess the system via a pressure sensor (42)
Patent
Process and device for checking the controllability of a tank ventilation valve
TL;DR: In this article, the controllability of a tank ventilation valve through which supplementary air carrying fuel vapours is supplied to the intake zone of an internal combustion engine is checked by measuring parameters which change when a flow exists through the valve.

Patent
Proportional flow fuel vapor purge control device
TL;DR: An engine has a fuel evaporative loss control system that includes a canister containing carbon for storing fuel vapors directed into it during engine hot soak conditions, and a purge line leading to the engine intake manifold and containing a purge control valve that meters the purge fuel vapores into the engine proportionate to the air flow rate into engine as discussed by the authors.
Patent
Fuel-vapor emission control system for an automotive engine
TL;DR: In this article, a fuel-vapor emission control system has a canister having a vacuum operated purge control valve, communicated with a float chamber of a carburetor and a fuel tank for purging fuel vapor.
Patent
Improvements in or relating to fuel systems for internal combustion engines
TL;DR: In this paper, the authors describe a system in which air from an air cleaner passes through a canister 2 of activated carbon under the control of a valve 6 and the rate of air flow through the canister may gradually and continuously increase or be increased in two or more steps.
