FIELD: physics.
SUBSTANCE: in the device, according to the invention, standard and spent gas containers have identical non-transparent channels darkened from the inside and sealed from the ambient environment; front covers of the channels at centre are provided with threaded bushings for screwing in eyepieces, inserting ends of light guides and cantilevers and their mounting; there are photodetectors on the inner surface of the front covers. Beyond the boundary of the focus of the lenses of the eyepieces across the channels, there are transparent partition walls for sealing photo-optical modules from gaseous media coming from below the channels through nozzles, as well as corrugated hoses, pneumatic cranes, a block of air filters and an exhaust gas probe-receiver having an elastic retainer in the opening of the exhaust pipe of the car. There are also sealed covers behind the channels, having nozzles underneath, corrugated hoses, a discharge manifold, controlled multi-position fluidic resistors, pneumatic ducts, control levers and pull rods for controlling the fluidic resistors, devices for measuring dynamic pressure in the channels and gas flow rate. All modules and components of the invention are mounted on a horizontal board and a front vertical panel with a telescopic support on wheels.
EFFECT: simple design and smaller size of the device, reduced power consumption and cost of the device.
