Turbocharger - Rebuilding
Description
A turbocharger is a mechanical device which uses the engine's exhaust gases to force more air into the engine
cylinders. A turbocharger uses energy from the engine to help increase its overall efficiency. Hot exhaust gas energy
is used to turn a "shaft and wheel". At the other end of the shaft and wheel is the "compressor impeller" (or
compressor wheel), which draws in air and forces it Into the engine cylinders.
Supplying increased air mass flow to the engine provides improved engine performance, lowers exhaust smoke
density, improves operating economy, altitude compensation, and noise reduction. The turbocharger has proven to
be one of the most beneficial devices for improving engine performance. It performs its job very well, as long as it is
properly cared for.
Identification
A Dataplate is located on the inlet side of the compressor
housing. Always write the assembly number of the
turbocharger, and turbocharger type on all orders for parts.
Note: The turbocharger Dataplate must not be changed
unless approved by Cummins Engine Co., Inc.
