Abstract

In a fuel injection apparatus the fuel quantities injected in the associated internal combustion engine are determined as a function of the angular position of a throttle member disposed in the air intake tube of the engine. The angular position of the throttle member, in turn, is variable by an electric follower regulator circuit that includes, in a bridge circuit, a temperature-dependent resistance which is disposed in a channel bypassing the throttle member and which changes its resistance as a function of the velocity and density of the intake air passing through said channel.
