turbochargers vs. superchargers: which is better? - most efficient air source heat pump

"Turbo" and "Turbo" are now part of the American vocabulary.
From politicians to television reporters to some comedians who are sitting in a car drinking coffee, they often say so.
While these two terms are generally understood to mean that something is given extra energy to become more powerful or highly emotional, accelerated or enhanced, most people don't understand the techniques that really give these words meaning.
What are the turbochargers and superchargers-
Which one is better?
More electricity requires more air.
Whether the internal combustion engine can be produced depends mainly on how much fuel it can burn, and the speed and efficiency at which it converts heat into mechanical forces.
But the fuel needs air.
Actually, the oxygen in the air)
Therefore, the maximum output of the engine depends largely on how much air is needed to burn the fuel.
So the concept of coercion-
Give the engine more air than normal so it can burn more fuel and generate more power.
This additional intake can be provided by a turbocharger or supercharger.
Both are air compressors, but they are very different in operation and performance.
Two technologies use a purpose turbocharger that takes advantage of the speed and heat of heat (and expanding)
The exhaust gas flowing out of the engine cylinder makes the turbine rotate, and the turbine drives a small compressor or impeller, thus delivering more air back to the engine.
The supercharger also delivers extra air to the engine, but it is mechanically driven by the engine through a belt or motor running from the crankshaft.
Pros and cons of these powers
Supercharging technology has advantages and disadvantages, but the most obvious difference from the rear wheel is a slight delay in the reaction to the right foot in a turbocharged car, especially when you go deep into the throttle.
This is because the supercharger takes a little time to "take off-line" before providing additional power"
When you step on the throttle, it takes a second for the exhaust heat and pressure to increase enough to rotate the turbine.
It is called "lift lag" or "turbo lag" for obvious reasons ".
In contrast, there is no lag in the supercharger;
Since its air pump is directly connected to the crankshaft of the engine, it always rotates and responds immediately.
The power boost it provides, so the engine response you feel through the pants seat will immediately be proportional to the distance you press the throttle.
While the main drawback of turbo is boost lag, the disadvantage of supercharger is efficiency.
Because the supercharger uses the engine's own power to rotate, it will suck the power --
With the engine speed rising, it is more and more.
For this reason, the fuel efficiency of the supercharged engine is often low.

The rear throttle response, however, is the supercharge rule.
It was hired by several big companies.

The winner is the car manufacturer, who decided that the advantages of the supercharger are great.
It's not so much a power issue as a fuel efficiency issue.
Federal demands ever made
Improve fuel economy, strict greenhouse-
Gas emission standards and customers' desire for good fuel mileage have prompted automakers to use turbocharging instead of superchargers.
Turbochargers enable automakers to replace many V-

High performance sports and luxury cars.
IHS Markit, a global information company, counted about 220 2018 models, including at least one turbocharged engine and only 30 turbocharged engines.
Swedish manufacturer Volvo decided not to choose between the two technologies.
It currently uses two types of power boosters

It is generally considered the rotational speed torque of the turbine lag, filling the power gap.
BorgWarner, the maker of the device, said the Supercharger "provides on-demand supercharging before the supercharger takes over, improves the supercharging effect at low engine speed, and virtually eliminates turbo lag.
"After driving the engine widely, we can confirm that it works on advertising.
It will soon be launched from the engines of at least two other automakers.
At the same time, we have a clear winner in these decades --
Long struggle between power
Upgrade Technology
At least according to car manufacturers, almost all of their current is turbo-charged.

But actually, this arm
The wrestling match continued.
There are signs that the future of the internal combustion engine will see both technologies working side by side. (
