Supercharger not to force Is your League

What is a supercharger? Suzuki IGNIS will start in the Tokyo Motor Show

The supercharger and Turbo are under the premise of not increasing the engine displacement, more compressed air into the engine combustion chamber (and spray more fuel) to increase the power output of the engine, just because they work differently. (On Turbo, we strongly recommend that you respond to "Turbo" rise up posture. ）

Supercharger is the crankshaft of the engine through the drive (belts, gears, and so on) and directly connected to the air compressor, driven air compressor rotor spins within the compressed air into the engine combustion chamber.

Also have used "compound Turbo system" (also called "double pressure"), is supercharged and turbocharged combination of series or parallel manner, was supercharged by two characteristics are complementary, for example: import Volkswagen Scirocco 1.4T has dual turbocharged version, the power can be comparable to some 1.8T turbocharged engine.

Supercharger and Turbo compare

1, power output

As long as the engine is running, supercharger system starts, can provide greater power at low engine speed, its power output is relatively smooth and feels similar to the a naturally aspirated engine, turbocharged engine technology is very good right now, but in terms of power output will have an imperceptible delay.

Supercharger system will consume part of the engine power to drive the air compressor, more at high speeds, mechanical supercharging effect is not obvious, (different types of supercharger, the effect is different), like most of the naturally aspirated engine.

2, fuel economy

Same row volume of two species booster in high-speed driving process in the, respectively not is big, but in speed driving or traffic not needed Booster system work, Turbo Booster not work, and mechanical booster in engine started Shi on has work, so in traffic or speed driving Shi, Turbo Booster engine to than mechanical booster engine province oil, this back everyone are know, why small displacement Turbo booster car in city sold of so fire has's (relative province oil, power also enough).

3, maintenance

Turbocharged engines are slightly more expensive than the supercharged engine, because turbochargers in the long-term under the environment of high temperature, high pressure, oil was affected by high temperature oxidation, turbocharged engines with relatively high quality oil, for example more than semi-synthetic oil. (More oil knowledge, reply "oil" to view)

While the supercharger working environment to be better than the turbo-charged work environment, but due to the mechanical precision booster design, so if you need to repair, supercharger maintenance costs than expensive turbocharged.

Overall: "small-engine + Turbo" combination of relatively fuel-efficient, explosive suitable for household models with smaller engines and superchargers are large enough with their displacement off-road and Sport models to become more fierce. In addition, in general the supercharger to be higher than the cost of Turbo.

Turbo and superchargers have different characteristics, but onions, "small-engine + Turbo" in energy depletion and increasing pollution now more popular crowd favorite.

Well today will give you so much knowledge about superchargers, hope to help everyone quickly forwarded up, let more people to know about it.
