[OT] Oh yeah, baby, TSI

[spewey at comcast.net (Spewey)]

Volkswagen now has TSI, a direction injection petrol engine dual-charged 
with a supercharger and turbocharger.

Here's how it works: the supercharger boosts torque and power at the 
lower end of the rev range - from 1,750 to 3,500rpm - with the turbo 
taking over at 3,500rpm and all the way to the 7,200rpm rev limit. This 
means that the TSI engine doesn't suffer from any turbo lag - the time 
before the turbo spins up to the point where it becomes effective at 
producing boost.

When you look at the specification and performance figures on paper of 
the new 1.4-litre TSI dual-charged petrol engine and you see it is more 
powerful, faster, more fuel efficient and less polluting than the 
relatively new 2.0-litre FSI direct injection petrol engine from VW you 
just cannot believe what you are reading is possible.

But it is I assure you. At last a petrol engine which drives like a 
diesel but is quieter although not quite yet as frugal with fuel. Turn 
the ignition key and the new 1.4-litre unit springs into life, no rattle 
or clatter as with diesel. Slip it into first gear and accelerate, 
change up to second, third, fourth and so on and there is huge amounts 
of power and more importantly torque making the car easy to drive at 
slow speeds in town or in traffic. On the open road, thanks to 
supercharger and turbocharger power, or a mixing of both, the engine is 
really responsive and strong during acceleration. There are no steps 
between these boosted stages, it is a petrol unit but it?s just like 
driving a diesel ? remarkable.
