2.5.1. Air consumption measuring instrument


Measuring instrument of a consumption of air of system of injection of K-Jetronic fuel

1 — Venturi's tube
2 — a pressure head disk
3 — the adjusting screw of quality (structure) of mix
4 — a counterbalance

5 — the lock screw
6 — a lead of a distributive plunger
7 — the adjusting lever
8 — the mobile lever of a pressure head disk

The measuring instrument of a consumption of air represents a tube of Venturi 1 in which the pressure head disk 2 fixed on the mobile lever 8 moves. Shift of a pressure head disk is transmitted through the lever on a distributive plunger of the batcher distributor of fuel. Balance of parallel movements of a pressure head disk of the measuring instrument of a consumption of air and a distributive plunger is provided with a counterbalance 4.

By means of the screw 3 the relative provision of a pressure head disk of a flowmeter of air and a plunger of a dosage of fuel is regulated, changing thereby a ratio of air and fuel in working mix in all points of a curve of acceleration. Position of the screw 3 is regulated at manufacturer. If necessary the screw 3 it is possible to adjust the content of carbon monoxide (SO) in the fulfilled gases (at its zavertyvaniye mix is impoverished).
