The catalog unit weight is 0.013 kg, which we use to estimate freight before quoting.
Technical Notes: Turbocharging
Turbochargers recover energy from the exhaust gas to compress the intake air. Their rotating parts run at very high speeds, so bearing and seal condition, balance, and clean oil supply decide service life. Larger MTU engines may use several turbochargers or sequential turbocharging, where turbochargers are switched in as load increases.
Series 1163 engines are known for sequential turbocharging, where additional turbochargers are switched in as load rises. Flap and control parts for the switching system are specific to the installation.
When This Type of Part Is Usually Replaced
- unusual noise, oil leakage into the intake or exhaust, or blue smoke appears
- charge-air pressure is lower than normal at the same load
- inspection shows blade damage on the turbine or compressor wheel
Checks Before Ordering
- Turbine wheels, compressor wheels, and housings are often specific to one turbocharger version; take the reference from the turbocharger nameplate
- Replace gaskets and oil-line seals when refitting a turbocharger
- Find the cause of a turbocharger failure, such as oil supply or foreign objects, before installing the replacement
