During the 1980s, the first large wave of vehicle turbocharging hit the showrooms. Turbochargers were found in anything from grocery-carrying Chrysler K-car station wagons to high-end Porsche sports cars. It seems to be a necessity that these turbocharged vehicles leave the factory with the word “TURBO” branded someplace, if not all over the vehicle. The truth is that a turbocharger may boost on-demand performance in an otherwise frugal engine. Turbocharged engines are becoming increasingly popular as customers demand greater horsepower while also getting better fuel economy.
In principle, it’s simple.
The turbocharger stands between the engine and the exhaust and redirects energy that would otherwise be wasted out of the tailpipe. Two finned wheels spin together on a shared shaft inside the turbocharger. The power of the exhaust is captured by the hot side turbine wheel. The energy captured by the turbine wheel is used to drive air back into the engine via the cold-side compressor wheel. The air is then combined with gasoline, and voila – a four-cylinder Chihuahua engine with the power of a Doberman V-8.
Because the compressed air pumped into the combustion chambers contains more oxygen, the engine may produce more power than it would if the turbo were not there. When the driver does not require more power, the turbo spins along for the ride, allowing the engine to run more efficiently.
Maintenance and greasing
While the turbocharger itself is a simple component, replacing it may be a costly proposition. A free replacement turbocharger can cost tens of thousands of dollars, not including installation and labor. To avoid early turbo failure, always adhere to the operator’s motor oil and servicing recommended.
Turbo engines may be quite demanding on motor oil. The hot side gets its moniker from the same exhaust that rotates the turbine rotor. The hot side housing might become noticeably red hot. Because the shaft may spin at speeds in excess of 100,000 rpm, utilizing high-quality motor oil is critical to turbocharger life.
Innovations in motor oil and moisture turbocharger enclosures have made turbocharged engines more user-friendly than ever before, yet failing to replace the oil may still mean the end of a turbocharger that before time.
In the final analysis
The cost of a new replacement turbocharger might be prohibitively expensive. If the breakdown is caused by normal wear, rebuilding may be a possibility. The bad news is that most do-it-yourselfers won’t be able to repair a turbocharger. Although disassembly and inspection may be possible, any machining and balancing would necessitate the use of specialist machinery as well as knowledge. The good news is that there are specialists available to manage the situation. A turbocharger repaired with new bearings and seals can last for many miles at a fraction of the expense of a new replacement unit.
