The Science Of Boost

By design, reciprocating engines are air pumps. They compress the aspirated air-fuel charge, ignite it, convert this expansion of hot gases into mechanical energy, and then expel the cooler, lower pressure gases. The amount of energy converted is determined by the pressure exerted on its pistons by combustion and the length of its expansion cycle. By increasing how aggressively a given mass of air-fuel charge is compressed, higher combustion pressures are achieved, allowing more energy to be extracted and thus creating more mechanical power output.
ROOTS SUPERCHARGER
In 1859 two brothers Philander Higley Roots and Francis Marion Roots founded The Roots Blower Company in Connersville, Indiana.
Roots superchargers operate by pumping air with a pair of meshing lobes resembling a set of stretched gears. The incoming air is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust of the blower.
TWIN-SCREW SUPERCHARGERS
In 1935, Swedish engineer Alf Lysholm patented a new air pump design as well as a method for its manufacture that improved upon the limitations of Roots blowers. Lysholm had replaced the lobes with screws, creating the rotary-screw compressor.
CENTRIFUGAL SUPERCHARGERS...
INTERCOOLERS
Forcing more air into a cylinder with boost easily creates more power in an engine by increasing the air mass of the intake charge beyond what is possible with natural aspiration. This also inherently pushes volumetric efficiency well beyond 100%
Because forced induction occurs outside of the engine the properties of the air mass can be further enhanced by cooling, by passing the compressed air through a heat-exchange device known as an intercooler.
TURBOCHARGERS
In some extreme cases, it can take as much as ⅓ of the base engine's power to drive the supercharger to produce a net gain in power.
The first turbocharger design was patented in 1905 by Swiss Engineer Alfred Büchi. He had conceptualized a compound radial engine with an exhaust-driven axial flow turbine and compressor mounted on a common shaft.
Turbochargers work by converting the heat and kinetic energy contained within engine exhaust gases, as they leave a cylinder. Radial inflow turbines work on a perpendicular gas flow stream, similar to a water wheel.
This shaft is housed within the center section of a turbocharger known as the center hub rotating assembly. Not only must it contain a bearing system to suspend the shaft spinning at 100,000s of RPMs, but it must also contend with the high temperatures created by exhaust gases.
In automotive applications, the bearing system found in most turbochargers are typically journal bearings or ball bearings. Of the two, journal bearings are more common due to its lower costs and effectiveness. It consists of two types of plain bearings; cylindrical bearings to contain radial loads and a flat thrust bearing to manage thrust loads.
Turbine aspect ratio - This is the ratio of the area of the turbine inlet relative to the distance between the centroid of the inlet and the center of the turbine wheel.
Compressors Trim -This is the relationship between the compressor wheels’ inducer and exducer diameter.
WASTEGATES
In order to prevent safe pressures and speeds from being exceeded, a mechanism called a wastegate is employed. Wastgates work by opening a valve at a predetermined compressor pressure that diverts exhaust gases away from the turbine, limiting its rpm. In its most common form, wastegates are integrated directly into the turbine housing, employing a poppet type valve. The valve is opened by boost pressure pushing a diaphragm against a spring of a predetermined force rating, diverting exhaust gases away from the turbine.
BLOW OFF VALVES
On engines with throttles, such as gasoline engines, a sudden closing of the throttle plate with the turbine spinning at high speed causes a rapid reduction in airflow beyond the surge line of the compressor. A blow-off valve is used to prevent this.
MULTI-CHARGING
Twincharging started to appear in commercial automotive use during the 1980s, with Volkswagen being a major adopter of the technology. In its most common configuration, a supercharger would feed directly into a larger turbocharger.
TWIN-SCROLL TURBOCHARGER
Twin-scroll turbochargers have two exhaust gas inlets that feed two gas nozzles. One directs exhaust gases to the outer edge of the turbine blades, helping the turbocharger to spin faster, reducing lag, while the other directs gases to the inner surfaces of the turbine blades, improving the response of the turbocharger during higher flow conditions.
VARIABLE GEOMETRY
Variable-geometry turbochargers are another example of turbocharger development. They generally work by allowing the effective aspect ratio of the turbocharger’s turbine to be altered as conditions change.

We used to do a trick on our bikes where we went full throttle, cut the ignition (thumb switch), filled the exhaust with air/fuel mixture, then thumbed the ignition back on. This ignited all the fuel in the exhaust at once and exploded like a quiet gunshot. Doesn't work on EFI. '(

I know diesel doesn't evaporate away like gasoline but how does it get their in the first place. I'm convinced that diesel users are absolutely animals when they refill the tank. They can't take 10 seconds to allow the fuel to finish draining out of the nozzle before pulling it out and getting it everyplace. I try to avoid the split pumps when getting gas as it never fails to get diesel all on the bottom of my shoes which I get to smell for the next hour or two. Maybe the pumps ALL suck and drip like an old man? Not sure..

    The Roots system is also used in metering natural gas at higher flow rates. For normal domestic metering, from 250 cfh to 1000 cfh, we usually use positive displacement diaphragm meters that use internal diaphragms to inflate and deflate, measuring the gas volume and turning a counter to show usage. This is then billed to a customer at a known pressure, adjusted for temperature. At higher volumes, 2m cfh to 56m cfh, we will use Roots style meters. They still work off of the positive displacement principle, yet the rotating assembly has a higher volume permission than a diaphragm design and do well at measuring large volumes of gas. They also aren’t restricted to the lower pressures of diaphragm meters, and some are used at upwards of 200 psig. This allows high pressure/volume through the meter, which a customer can then regulate down for their specific applications.

    Twin Scroll and GMs recent Twin Volute systems are great advancements in TC. Toyota/Lexus uses both port injection with direct injection and VVT to operate in a modified Atkinson cycle at times. The tech that is going into these modern 4 cylinders is truly remarkable. They are compact efficient powerful and simpler in some ways.

    This was actually very well done. Bravo. Only critique: 17:10 - Turbos are not just RPM dependent. They are also load dependent. This is why redlining in neutral builds no boost but flooring it at low RPM can. For best results, it takes both.

    the best video for the beloved turbo amazing work . i want to add a couple of things the split turbo and the electic turbo ,the first has has the cold side and the hot side of turbo splited and the benefit is the hot side doesnt increases the temp of the cold air that is coming in the cold side so way more air can come to the system(first manufacturer is Mercedes ) and the second is a small turbine that is driven by electricity to send air to the way bigger normal turbo so it doesnt have lag(first manufacturer Audi/VAG) :)
