ABSTRACT:
In a computer for calculating the optimum mixture of combustion agent and fuel for an internal combustion engine, of the type comprising a monostable univibrator operating in synchronism with the rotational velocity of the engine and generating electric pulses of a width subordinate to the value of the voltage measured by a probe for making the chemical analysis of the gases in the exhaust manifold, the thus measured voltage being processed in a regulator provided with an intermediate integrator, said electric pulses being utilized for determining the opening time of a solenoid valve controlling the output of a fluid, whether combustion agent or fuel, of which the metering is measured by said probe, provision is made of a bistable univibrator coupled at one end to the output of a first comparator having one input connected to said chemical analysis probe via an integration type regulating circuit, said univibrator being connected at its other input to a pulse generator opening in synchronism with the rotational movement of the engine, by one of its outputs to an integrator comprising a current amplifier in series with a capacitor and connected to the second input of said first comparator, said one output being also connected to the device controlling the opening time of said solenoid valve, and by its other output to one input of a discharge device for said capacitor.
