Vehicle inspections with rigid and flexible Technoscopes

chnoscopes

The Technoscope (technical endoscope) is an optical diagnostic device lor visual inspection ol cavities in vehicles and engines. Technos­copes specially constructed lor the motor industry mean thai today almosl all ports ot a vehicle can be inspected without dismantling. This includes valves, cylinder surfaces, piston heads, cylinder heads of Otto and Diesel engi­nes. Cavities in the car body or coachwork, gearbox, brakes and even tuel tanks can be "illuminated".

There are two basic types of Technoscope:

1. Rigid Technoscopes: These well-known "rods' have proved themselves in many applications and belong to fhe standard equipment of many workshops.

2. Flexible Technoscopes have found wide­spread use in other branches of industry for many years A flexible vehicle Technosco­pe is on innovation suitable for vehicle work-shops for inspecting the new, extre­mely compact generalion of engines.

The illumination for both Technoscope types is provided by a separate light source. The halo­gen light produced is guided fo the inspection site by an extremely flexible glass fibre light cable and is emitted via the tip of fhe Tech­noscope. This is known as cold lighf because the lip of Ihe Technoscope is not heated by the extremely bright light. This is particularly advantageous when illuminating wax-sealed cavities or when inspecting a petrol tank.

For general inspections on vehicles, rigid Technoscopes with on angle of view of 70° are suitable. In multi-valve engines, fhe thin bridges between Ihe valves in the cylinder head and Ihe valve discs can be visualised with a special 112° "retrograde" Technosco­pe. In Ihe flexible vehicle Technoscope, the viewing tip is controlled or dellecled by o con­trol lever on the handle so that Ihe angle of view varies from -90° fo -280°.

R. WOLF Technoscopes provide an image that is sharp right up to the edges, has high-fideli­ty colour, is not inverted and has a high degree of contrast. Even the slightest damage, conta­mination or corrosion can be seen. Remova­ble reintorcing lubes protect Ihe high-quality optical systems in rough every day use.

When inspecting already installed engines, Ihe Technoscope can be inserted but there is often not enough space to gel to the eyepiece (this is typically Ihe case with V engines). In this situation, an optical angled attachment fitted to the Technoscope is makes viewing possible. In extremely narrow spaces, the fle­xible Technoscope is Ihe ideal solution.
