WHAT IS A TURBOCHARGER AND HOW DOES IT WORK?
A turbocharger is a device fitted to a vehicle's engine that
is designed to improve the overall efficiency and increase performance. This is the reason why many auto manufacturers are
choosing to turbocharge their vehicles. The new Chevrolet Trax and Equinox are both offered with turbocharged engines and as
time goes on, more and more vehicles will be fitted with them. Obviously,, different brands of vehicles need different kinds
of turbocharger to fit, for example, there are
Turbocharger for Audi, Turbocharger for Seat
, Turbocharger for Skoda,
Turbocharger for Volkswagen,
Turbocharger for BMW,
Turbocharger for Mercedes-Benz,
Turbocharger for Toyota,
Turbocharger for Volvo,
Turbocharger for Hyundai, etc.
How does it work?
A turbo is made up of two halves joined together by a shaft. On one side, hot exhaust gasses spin the turbine that is
connected to another turbine which sucks air in and compresses it into the engine. This compression is what gives the engine
the extra power and efficiency because as more air can go in the combustion chamber, more fuel can be added for more power.
Advantages
In addition to the extra power, turbochargers are sometimes referred to as devices that offer "ree power"
because unlike a supercharger, it does not require the engine's power to drive it. The hot and expanding gasses coming
out of the engine are what power a turbocharger so there is no drain of the engine's net power. Turbocharged engines are
also not affected in the same way as naturally aspirated engines are when they go at higher altitudes. The higher in altitude
a naturally aspirated engine climbs, the harder it becomes for it to get oxygen due to the thinning atmosphere. A
turbocharger gets around this problem because it forces the oxygen into the engine's combustion chamber, sometimes at 2
times the pressure of the atmosphere.
Turbochargers also improve the fuel efficiency of a vehicle however there is a misconception when it comes to
turbocharged vehicles and fuel efficiency. Taking a naturally aspirated engine and slapping on a turbocharger on it will not
improve fuel efficiency. The way that manufacturers improve fuel efficiency though turbocharging is by down-sizing an engine
and then turbocharging it. For example, take a 2.5L inline-4 cylinder naturally aspirated engine and decrease the
displacement to 1.4L and then turbocharger it. The smaller, turbocharged engine would still have the same performance figures
(or slightly better) but because of the smaller displacement, it would also use less fuel.
Disadvantages
Turbochargers have 2 main disadvantages when compared to a naturally aspirated or supercharged engine. Firstly is heat.
Because a turbo is powered by hot exhaust gasses, it gets very hot. Sometimes under certain engine conditions, the
turbocharger itself could start glowing red but of course this doesn't happen in everyday driving conditions; it happens
when the engine is pushed to its limits for a continuous amount of time. This is why you see some turbocharged sports cars
with vents in the hood or down the side, it's to try to get air moving through the engine bay and keep things cool.
The other big disadvantage of a turbocharger is something called turbo lag. Under certain conditions, whenever you put
your foot down on the throttle, there is a delay between the time you demand power from the engine and the moment you
actually start to feel it. That is turbo lag. When the engine's speed is low, there isn't a lot of exhaust gasses
passing through the turbocharger so when you do demand power from the engine, the turbocharger turbine needs time to start
spinning at an optimal speed. The effects of this can be reduced by downshifting to a lower gear but keen drivers can still
sometimes notice the split delay in response.
So the next time you're in a GM showroom, don't overlook the turbocharged vehicles. They offer the same or more
power as V6 or sometimes even V8 counterparts and they usually have better fuel economy due to the smaller displacement
engine and less weight.
