hello and welcome back to another edition of ProTech
today we're going to cover the basic function and benefits of turbochargers
The first thing we should do is go over how these things work
A turbocharger uses the engines exhaust gas to drive a turbine wheel at speeds up
to 280,000 rpm
the turbine wheel is connected by a shaft to compressor wheel and the two
wheels turn together to suck in and compress large amounts of ambient air
air is very dense and very hot
so it's passed through a charge air intercooler like a radiator where cools and
gains even higher density before entering the engine
the presence of this compressed air makes the fuel burn more efficiently
thereby delivering greater power and consuming less energy
turbos are increasingly coupled with high pressure fuel injection systems
a combination that makes it even more thorough efficient and cleaner
combustion
now that we know how turbos work let's talk about the benefits that they
provide
turbocharged gasoline engines are more efficient. Delivering up to
30% better fuel economy over a non turbocharged equivalent
diesel engines the benefits are even greater
a turbo diesel engine of the same power rating delivers up to
40% better fuel efficiency compared to a non boosted gas engine
which is why a 100% of the current diesel vehicles are
turbocharged
along with improving
fuel economy
turbos also improve vehicle performance
by creating more power and torque
on top of the performance and fuel consumption benefits
turbocharged engines are even better for the environment
their operated for free on otherwise wasted exhaust gas
well optimizing engine air for cleaner combustion allowing for smaller engines
without compromising performance
for consumers turbocharged engines are attractive option that requires no
compromise on performance and fuel efficiency
while retaining the fun of driving
this explains why there has been such an increase of turbocharged vehicles
appearing on the road any in OEM future lineups
I hope this information has been insightful and informative
in future segments
we'll cover some common issues that occur with turbos and how to resolve them
thanks for your time and I'll see you on our next addition of ProTech
