Reducing the "boost threshold rpm" can improve throttle response. Many turbocharger installations use additional technologies , such as wastegates, intercooling and blow-off valves.
Energy provided for the turbine work is converted from the enthalpy and kinetic energy of the gas. The turbine housings direct the gas flow through the turbine as it spins at up to , rpm.
Often the same basic turbocharger assembly is available from the manufacturer with multiple housing choices for the turbine, and sometimes the compressor cover as well.
This lets the balance between performance, response, and efficiency be tailored to the application. The turbine and impeller wheel sizes also dictate the amount of air or exhaust that can flow through the system, and the relative efficiency at which they operate.
In general, the larger the turbine wheel and compressor wheel the larger the flow capacity. Measurements and shapes can vary, as well as curvature and number of blades on the wheels.
A turbocharger's performance is closely tied to its size. Small turbochargers spin quickly, but may not have the same performance at high acceleration.
Twin-turbo or bi-turbo designs have two separate turbochargers operating in either a sequence or in parallel. In a sequential setup one turbocharger runs at low speeds and the second turns on at a predetermined engine speed or load.
Two-stage variable twin-turbos employ a small turbocharger at low speeds and a large one at higher speeds. They are connected in a series so that boost pressure from one turbocharger is multiplied by another, hence the name "2-stage.
Twin turbochargers are primarily used in Diesel engines. Both turbochargers operate together in mid range, with the smaller one pre-compressing the air, which the larger one further compresses.
A bypass valve regulates the exhaust flow to each turbocharger. At higher speed 2, to 3, RPM only the larger turbocharger runs. Smaller turbochargers have less turbo lag than larger ones, so often two small turbochargers are used instead of one large one.
This configuration is popular in engines over 2. Twin-scroll or divided turbochargers have two exhaust gas inlets and two nozzles, a smaller sharper angled one for quick response and a larger less angled one for peak performance.
With high-performance camshaft timing, exhaust valves in different cylinders can be open at the same time, overlapping at the end of the power stroke in one cylinder and the end of exhaust stroke in another.
In twin-scroll designs, the exhaust manifold physically separates the channels for cylinders that can interfere with each other, so that the pulsating exhaust gasses flow through separate spirals scrolls.
With common firing order 1—3—4—2, two scrolls of unequal length pair cylinders 1 and 4, and 3 and 2. This lets the engine efficiently use exhaust scavenging techniques, which decreases exhaust gas temperatures and NO x emissions, improves turbine efficiency, and reduces turbo lag evident at low engine speeds.
Cut-out of a twin-scroll exhaust and turbine; the dual "scrolls" pairing cylinders 1 and 4, and 2 and 3 are clearly visible. Variable-geometry or variable-nozzle turbochargers use moveable vanes to adjust the air-flow to the turbine, imitating a turbocharger of the optimal size throughout the power curve.
Their angle is adjusted by an actuator to block or increase air flow to the turbine. The result is that the turbocharger improves fuel efficiency without a noticeable level of turbocharger lag.
The compressor increases the mass of intake air entering the combustion chamber. The compressor is made up of an impeller, a diffuser and a volute housing.
The flow range of a turbocharger compressor can be increased by allowing air to bleed from a ring of holes or a circular groove around the compressor at a point slightly downstream of the compressor inlet but far nearer to the inlet than to the outlet.
The ported shroud is a performance enhancement that allows the compressor to operate at significantly lower flows.
It achieves this by forcing a simulation of impeller stall to occur continuously. Allowing some air to escape at this location inhibits the onset of surge and widens the operating range.
While peak efficiencies may decrease, high efficiency may be achieved over a greater range of engine speeds.
Increases in compressor efficiency result in slightly cooler more dense intake air, which improves power.
This is a passive structure that is constantly open in contrast to compressor exhaust blow off valves, which are mechanically or electronically controlled.
The ability of the compressor to provide high boost at low rpm may also be increased marginally because near choke conditions the compressor draws air inward through the bleed path.
Ported shrouds are used by many turbocharger manufacturers. The centre hub rotating assembly CHRA houses the shaft that connects the compressor impeller and turbine.
It also must contain a bearing system to suspend the shaft, allowing it to rotate at very high speed with minimal friction. For instance, in automotive applications the CHRA typically uses a thrust bearing or ball bearing lubricated by a constant supply of pressurized engine oil.
The CHRA may also be considered "water-cooled" by having an entry and exit point for engine coolant. Water-cooled models use engine coolant to keep lubricating oil cooler, avoiding possible oil coking destructive distillation of engine oil from the extreme heat in the turbine.
The development of air- foil bearings removed this risk. Ball bearings designed to support high speeds and temperatures are sometimes used instead of fluid bearings to support the turbine shaft.
This helps the turbocharger accelerate more quickly and reduces turbo lag. When the pressure of the engine's intake air is increased, its temperature also increases.
This occurrence can be explained through Gay-Lussac's law , stating that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
In addition, heat soak from the hot exhaust gases spinning the turbine will also heat the intake air. The warmer the intake air, the less dense, and the less oxygen available for the combustion event, which reduces volumetric efficiency.
Not only does excessive intake-air temperature reduce efficiency, it also leads to engine knock, or detonation , which is destructive to engines.
To compensate for the increase in temperature, turbocharger units often make use of an intercooler between successive stages of boost to cool down the intake air.
A charge air cooler is an air cooler between the boost stage s and the appliance that consumes the boosted air. There are two areas on which intercoolers are commonly mounted.
It can be either mounted on top, parallel to the engine, or mounted near the lower front of the vehicle.
Top-mount intercoolers setups will result in a decrease in turbo lag, due in part by the location of the intercooler being much closer to the turbocharger outlet and throttle body.
This closer proximity reduces the time it takes for air to travel through the system, producing power sooner, compared to that of a front-mount intercooler which has more distance for the air to travel to reach the outlet and throttle.
Front-mount intercoolers can have the potential to give better cooling compared to that of a top-mount. The area in which a top-mounted intercooler is located, is near one of the hottest areas of a car, right above the engine.
This is why most manufacturers include large hood scoops to help feed air to the intercooler while the car is moving, but while idle, the hood scoop provides little to no benefit.
Even while moving, when the atmospheric temperatures begin to rise, top-mount intercoolers tend to underperform compared to front-mount intercoolers.
With more distance to travel, the air circulated through a front-mount intercooler may have more time to cool. Adding the mixture to intake of the turbocharged engines decreased operating temperatures and increased horse power.
Turbocharged engines today run high boost and high engine temperatures to match. When injecting the mixture into the intake stream, the air is cooled as the liquids evaporate.
Inside the combustion chamber it slows the flame, acting similar to higher octane fuel. In addition to the use of intercoolers, it is common practice to add extra fuel to the intake air known as "running an engine rich" for the sole purpose of cooling.
The amount of extra fuel varies, but typically reduces the air-fuel ratio to between 11 and 13, instead of the stoichiometric The extra fuel is not burned as there is insufficient oxygen to complete the chemical reaction , instead it undergoes a phase change from atomized liquid to gas.
This phase change absorbs heat, and the added mass of the extra fuel reduces the average thermal energy of the charge and exhaust gas.
Even when a catalytic converter is used, the practice of running an engine rich increases exhaust emissions. A wastegate regulates the exhaust gas flow that enters the exhaust-side driving turbine and therefore the air intake into the manifold and the degree of boosting.

The pilot must also take care to avoid over-boosting the engine and causing damage. In contrast, modern turbocharger systems use an automatic wastegate, which controls the manifold pressure within parameters preset Missing: Deutsch. The "one man, one engine" philosophy means that one engineer at the engine plant in Affalterbach takes responsibility for the entire assembly of each AMG high-performance engine - as evidenced by that mechanic's signature on a special engine badge, which, in the case of the AMG V8 supercharged engine, is located on the supercharger module. supercharged definition: 1. very fast or energetic: 2. containing or expressing very strong emotions: 3. very fast or.
