Abstract
An engine diagnostic tool for simulating turbocharger operation within an engine of a motor vehicle, while the engine is not running, includes a turbocharger with an air inlet, an inner surface and an outer surface. The diagnostic tool includes a plug adapted to sealingly engage the inlet of the turbo. The plug includes an aperture for supplying pressurized air to the inlet. The diagnostic tool also includes a clamp adapted to selectively restrict movement of the plug relative to the inlet. The clamp is adapted to be removably coupled to the inlet.
Claims17
A tool to facilitate operation of a turbocharger within an engine of a motor vehicle while the engine is not running, the turbocharger including an air inlet with an inner surface and an outer surface, the diagnostic tool comprising:
- a plug adapted to sealingly engage the inlet of the turbocharger, said plug including an aperture for allowing pressurized air from an air source to pass therethrough to cause operation of the turbocharger;
- and
- a clamp adapted to selectively restrict movement of said plug relative to the inlet, said clamp adapted to be removably coupled to the inlet.
A method of operating a turbocharger connected to an engine without running the engine, the method comprising:
- inserting a plug within an inlet of said turbocharger, said plug having an aperture therethrough and sealingly engaging said inlet;
- securing a clamp to said inlet, said clamp restricting movement of said plug;
- and
- coupling a source of pressurized air to the plug to pressurize said inlet via pressurized air flowing from the source and through the aperture in the plug.
