The exhaust gas extraction made of flexible pipes and equipped with special nozzles, to be positioned near the end of the exhaust system of the vehicle.
Proximity but with adequate precautions in such a way as not to compromise the fluid dynamics of the exhaust system (and through the valve crossing phase, if 4T engines, also the intake phase) and distort the performance measured during the test.
In addition to the exquisitely technical precautions, practicality of use, stability in operation, easy mobility, an effective immobilization system both on the horizontal and vertical plan must be considered.
All of the above is realized in the range of trolleys for supporting smoke nozzles developed by us:
Mobile trolley on 4 swivel wheels, the two rear ones equipped with snap brake.
High mass: 40 kg of weight make it stable even in the most energetic flames of exaggerated racing engines!
Height positioning of the mouthpiece in 7 cm steps by means of a handle and a release lever: height and position achievable with one hand.
Available in various nozzles diameters, heights, number of positions.
