Hopefully this article will be useful for you. If you have any car question, feel free to leave us a comment in the box below, we will answer it for you. A turbocharger is a turbine-driven forced induction machine that boosts the efficiency and power output of an internal combustion engine by bringing additional air into the combustion chamber. We’ll have a look at the detail of the sort of boost control systems you can expect to find in the next instalment but before that, what about the turbo itself? Basic turbochargers are fairly straightforward in that they comprise castings, nuts, bolts and studs to hold everything together, a spindle running in bearings through the turbo casings, with the turbine on the hot end and compressor wheel on the other. There could be nothing more to it than that or there may be a wastegate mechanism incorporated into the casing. Simple, yes, and the temptation to have it apart on the bench and fit some new bits is great, but this is one that’s best left to the experts with the right equipment. The Garrett T3 from a Sierra Cosworth. There’s one particular reason for this and that’s balance. The Garrett T3 fitted to cars like my Ford Sierra Cosworth will reach 110,000rpm and the only thing between its compressor and the engine is the intercooler. Catastrophic turbo failures resulting in fragments being swallowed by the engine don’t bear thinking about and a specialist will balance the assembly and rebuild the turbo to factory specifications. In the UK, Owen Developments is a well known purveyor of all things turbo and there’s also Bernie Wilky of Bernie’s Blowers fame who can be found on Facebook. Another benefit of using turbochargers is that they enable the engine to yield more torque at the lower rev range, which gives a car an edge while driving around the city. The additional torque comes handy for easily pinching the gaps.

The diesel-run cars mainly have a turbocharged engine. In addition, most automakers have one or two turbocharged models in their line of products. To name a few, Renault-Nissan has labeled their turbo-diesel as dCi and turbo-petrol as TCi, which are TDI and TSI for Volkswagen and TDCI and Ecoboost for Ford, respectively. However, superchargers can produce a better throttle response because of their more direct and mechanical connection to the engine. Unlike the turbos, there is no lag to delay the response. What Car Models Have the Turbo Engine?

At a certain point that pressure has to be nipped in the bud and that’s when the control system does its stuff. Mechanical wastegate actuators are opened by pressure from the boost side of the turbo acting on a diaphragm inside the actuator. That opens a simple valve on the hot side allowing exhaust gas to bypass the turbine. At the same time, inlet boost pressure must be released and that’s what the cold side pressure relief valve does. Left: A Garrett turbocharger. Right: A T-piece sending pressure to a boost gauge. The turbine rotates at a high speed and spins the compressor too as both are mounted on the same shaft. I suppose it’s a generation thing to some extent but when I think of classic car induction systems my mind wanders off to SU or Weber carburettors. Turbos still seem relatively modern since virtually every current car has one, but of course they’re not. Plenty of modern classics from the 1980s and a tiny minority from before that have them – take the Saab 99 Turbo that featured in this year’s Bull Market List, for example – but the good news is that sorting out a problem is usually more mechanical than electronic.
