ABSTRACT:
A warm-up regulator device for enriching the air-fuel mixture delivered to an internal combustion engine during the engine warm-up phase, said engine having a fuel-metering system with a switching arrangement for generating metering signals in response to a group of engine operating parameters, a compensation stage for correcting the metering signals and a fuel-metering means, wherein the compensation stage is connected to a function generator for producing a signal which is speed-responsive to compensate for condensation losses in the walls of the fuel lines and engine when the engine is cold thus optimizing the operation of the engine. Also disclosed are several ways for reducing the compensation for condensation losses at higher speeds to prevent a negative affect on the exhaust gases and to match the regulator to various engines.
