Turbocharging is very familiar with diesel engines for the reason that they are suitable very well for turbocharging. Turbocharger vs Supercharger; to each their own, be it a turbocharger or a supercharger. Both these induction systems have a purpose to fulfil. Both these system work in order to squeeze the maximum ounce of power and torque from an internal combustion engine.
However, car manufacturers have determined that the turbocharger wins over supercharger by a relative margin, not on power but providing best fuel efficiency. Air compression increases its temperature; thus, it is general to use an intercooler to decrease the temperature of the air among the pump and engine. Yes, using a turbocharger in tandem with a supercharger is very much possible.
However, twin-charging is on possible in petrol-powered cars. Diesel-powered cars have the limitation of producing high torque at low RPM. As the supercharger works out the engine RPM, the fuel efficiency also increases.
It is a quick and efficient way to increase the performance of a vehicle. Turbo lag is defined as the time it takes between smashing the accelerator and feeling the rush of torque from a turbocharged engine. Basically, a turbo lag is the time, a turbocharger takes to take in the air, spool and provide the gush of power to the engine.
The new Volvo models are the most mainstream cars in the US to use a twin-charged setup. Perhaps we will start to see more companies use this unique engine configuration. We mentioned that the new Volvo models were the most mainstream car in the US to have a twin-charged engine because Europe has had many of them over the years. The Volkswagen Group built a 1. This little hatchback may not look like much, but is actually extremely unique.
This Nissan March is a special homologation special built in as a 10, unit limited run. It was called the March Super Turbo because of its unique cc twin-charged inline-four engine. This tiny powerplant put out hp, which is not bad for such a small engine.
The engine was paired to a three-speed automatic or a five-speed manual with a limited-slip differential. Despite the low power, this car could hit 60 mph in 7.
The Lancia Delta S4 was a Group B rally car that raced in and before the series was disbanded. The rules of the race stipulated that Lancia had to build road-legal versions of the car. The car was called the Delta S4 Stradale and it was sold for just two years. One manufacturer, Swedish maker Volvo, decided not to choose between the two technologies. It currently employs both types of power boosters—a small, conventional engine-driven supercharger for low-end response and a turbocharger for higher-rpm power—on some of its 2.
Recently, a third power-boosting alternative has come to market: electric supercharging. An electric motor spins a compressor to provide a burst of low-rpm torque that fills in the gap in power normally felt as turbo lag.
It will soon be available on engines from at least two other automakers. Meanwhile, we have a clear winner in this decades-long battle between power-boosting technologies—at least according to car manufacturers, who have chosen turbocharging for almost all of their current-production power-boosted engines. But in reality, this arm-wrestling match rages on. Indications are that the future of internal combustion engines will see both technologies working side by side.

Sensors then determine how much, and instruct the fuel system to add the appropriate amount of gasoline to blend the correct air-fuel mixture. Adding more air would allow for more fuel, but a naturally aspirated engine one without a turbocharger or supercharger is limited in how much air it can take in. When air is pumped in under pressure — the job of those forced-air chargers — more fuel can be delivered, and the engine makes more power.
One side is located at the exhaust manifold where spent gases are expelled, and the other at the intake where fresh air comes in. Inside the turbo are two small fans, joined together by a shaft. As exhaust gas flows through the turbo, it spins one of the fans, called the turbine. The shaft turns, spinning the second fan, called the compressor. This fan draws in fresh air, pressurizes it, and forces it into the engine. A supercharger works similarly in that it compresses air and forces it into the engine, but its fan is driven by the engine.
A supercharger provides boost almost immediately, but the engine uses some of its energy to drive the unit, known as parasitic loss. One way of getting around turbo lag is to install two turbochargers: A small one that spins up faster, and a larger one that provides more power at higher speeds.
Twin-charging does the same.
