TLDR
In this article, an afterburner is formed as an after-burner to receive the exhaust gases and burn CO and unburned hydrocarbons; connected in series therewith, downstream, is a catalytic reactor to reduce nitrogen oxides.Abstract:
A thermo reactor is formed as an after-burner to receive the exhaust gases and burn CO and unburned hydrocarbons; connected in series therewith, downstream, is a catalytic reactor to reduce nitrogen oxides. An oxygen sensor is exposed to the exhaust gas stream between the thermo reactor and the catalytic reactor and supplies a control signal to an amplifier which, in turn, controls one or both of the components air and fuel of the fuelair mixture to the engine in such relative proportions of mass that the exhaust sensed by the sensor is just slightly below the stoichiometric ratio of air and fuel ( lambda 1.0).read more

Fuel control system for an internal combustion engine
TL;DR: In this paper, a roughness sensing circuit is used to produce roughness signal output dependent on the magnitude of fluctuations of engine speed, which is applied to an integrator which provides a limited authority trim signal to the fuel control in accordance with the time integral of the error between the roughness signals and a speeddependent reference signal generated by a speed-shaping circuit.

Closed-loop mixture control system for an internal combustion engine using sample-and-hold circuits
Shigeo Aono,Masaharu Asano +1 more
TL;DR: In this article, a closed-loop mixture control system for an internal combustion engine comprises an exhaust composition sensor, a comparator for comparing the signal derived from the sensor with a reference point to determine whether the air-fuel ratio of the mixture is above or below a desired value, and a sample-and-hold circuit for sampling the comparator output at intervals equal to or longer than the transport delay time of the engine and holding the sampled signals until the next sampling occurs.
