turbocharger will be basically a hair dryer, which adds horsepower. Exhaust-driven turbine wheel spins air centrifugal compressor to improve the amount of air feeding the cylinders. Additional air, along with more fuel, boosts power along with torque. The following technologies allow more production, increase efficiency, or less backward compared with the one, the primary turbocharger:

Legend

Sequential Turbos

Turbo sequential

here, smaller spools turbo fast low-end response while the larger unit enhances high-end power with larger quantities of exhaust. Sequential devices by favor along with retreated because they require complex controls along with packing a huge packaging, along with recent developments reduced delayed-buffering even in single along with dual turbo setups
found in: Nissan Titan XD diesel , Audi SQ7 TDI

Twin Scroll

TWIN SCROLL

exhaust manifold along with turbine housing division of the exhaust into separate currents. This particular improves the timing pulses exhaust delivered to the turbine wheel, along with improve the response when the throttle position adjustments suddenly
found in: BMW 328I

Variable Geometry Turbine

variable turbine geometry

vanes movable inside turbine to change the entrance angle along with the speed of the exhaust gases before they reach the turbine wheel. At low flow rates, the vanes form the narrow openings that will accelerate the exhaust gas to reduce the delay. Electrical controls or airway open rotors to allow large exhaust size to pass through at high loads
found in: Porsche 911 Turbo

Twin Turbos [Hiklngveh

TWIN Turbo

two equal-sized informants by half-cylinder engine. Using two turbines instead of one leads to the wheels of turbines along with little compressors that will caching faster due to the low inertia
found in: Ford F-150 motor shows



Overboost

enhanced additional overboost

a temporary increase in pressure increase raises the temperature of power, torque, along with exhaust. a different booster overboost usually limited to 10 to 20 seconds mutations to avoid high temperature components along with cause a catastrophic failure
found in: Ford Focus ST
