An apparatus and method for diagnosing mechanical problems in turbocharged engines. In its preferred embodiment, the apparatus consists of a boot that is coupled to a turbocharge system-preferably at the air inlet thereof. The, apparatus further includes a source of air pressure that may be delivered to the turbocharge system, a first pressure gauge to measure the pressure of the air that is being delivered, and a second pressure gauge to measure the pressure of the air within the turbocharge system. Under pressure, and with the engine off, the turbocharge system can be inspected for leaks. In addition, under pressure, the operation of turbocharge system components-such as the wastegate valve / diaphragm and the boost sensor-can also be inspected.

The invention includes linkage assemblies comprising coupled links with metallic contact surfaces with improved stiffness. The inventors found significant mechanical problems with all previous descriptions of metallic contact links sufficient to preclude their commercial use. These metallic contact links are a significant improvement over existing plastic ball and metal joint, or all plastic beads as found in the prior art. The invention includes methods providing these links and high friction couplings between them, as well as the linkage assemblies and flexible arms resulting from these processes.

The invention relates to a system for signalling and locating vehicles involved in accidents, stopped vehicles and vehicles with mechanical problems in daytime and night-time conditions as well as in adverse weather conditions. According to the invention, the occupants of the vehicle can raise the alarm without leaving the vehicle such as to avoid any physical risk. The invention comprises a case and a hinged cover housing an air container. One end of the air container is connected to a gaseous fluid outlet pipe and to a manual quick-opening non-return valve which is located in the mouth of an empty aerostatic inflatable fluorescent body. The aforementioned body is folded inside the case when not in use and is deployed in the event of a vehicle impact by means of a device comprising an inertia sensor which is activated by a deceleration force exceeding 3G and which is powered by a power source comprising batteries or accumulators belonging to the electric circuit of the vehicle or independent batteries. Said source is solidly connected to an electrically-conductive cable terminating in a connector which is associated with a light flashing apparatus comprising an electronic flash unit, a light sensor which operates at night and a satellite-based mini-localizer comprising a global positioning system (GPS).
