Abstract
1468838 Regulating IC engines LARS COLLIN CONSULT AB 11 Feb 1974 [15 Feb 1973] 06152/74 Heading F1B [Also in Division G1] Apparatus for determining certain gases, for example the carbon monoxide, hydrocarbon and nitrogen oxides content of vehicle engine exhaust gases comprises a device for operating the fuel supply system of the engine, which is to be disengaged from the transmission, in accordance with a predetermined program to cause over a fixed period of time at least one momentary increase in fuel supply sufficient to raise the speed of the engine to a speed not exceeding the maximum value, and a gas sampling unit for connecting to the engine exhaust to collect a given fraction of the exhaust gas and to determine the certain gases in the given fraction. In the apparatus shown, the throttle pedal 28 is operated as required by an electronic control unit 29 by a compressed air motor 36 which is governed by a solenoid operated valve 37 controlled by unit 29 and fed with air from bottle 40. A given fraction of the exhaust gases from exhaust pipe 27 is collected in bladder shaped bag 31 by attachment of hose 33 to one of a series of pipes 32 which are connected to exhaust gas receiver 30 and are of accurately determined length and i.d. The exhaust gas fraction collected may be led through an absorbing indicator mixture or to analyzing equipment.
