An internal combustion engine's efficiency and power output are increased by a turbocharger (or turbo), a turbine-driven forced induction device, by forcing more air into the combustion chamber. The compressor's ability to pump more air—and thus more fuel—into the combustion chamber than atmospheric pressure alone accounts for this increase in power output over a normally aspirated engine. A turbocharger's goal is to boost an engine's efficiency by raising the density of the intake gas (often air), which results in more power being produced each engine cycle.
Symptoms of turbocharger failure
There are several signs you can look out for to tell if your turbocharger has blown:
- Loss of power
Decreased engine power and acceleration.
- Excessive exhaust smoke
Blue or black smoke indicating oil leaks.
- Unusual noises
Whining or grinding sounds from the turbo.
- Check engine light
Dashboard warning indicating potential turbo issues.
- Increased oil consumption
Higher oil usage suggesting leaks from the turbo.
- Poor fuel economy
Decreased fuel efficiency due to compensatory engine work.
- Overheating
Higher engine temperatures affecting performance.
