A supercharger is a mechanically driven pump that forces more air into the cylinder. When the driver lifts off the accelerator pedal, the exhaust gases and inertia of the wheels keep the turbo spinning for a while. Full access requires DieselNet subscription.

  • BorgWarner's e-booster kills the much-hated turbo lag. While any self-​respecting futurist foretells a world of electric driving, the engineers.

    Turbocharger Integrated Assist

    Turbo lag is therefore defined as the gap between the throttle being actuated and the Using an electric motor between the inlet and outlet of the turbocharger. The new turbocharger is powered by an electric motor instead of exhaust gases.

    has developed an electric turbocharger that it says eliminates "turbo lag. Valeo says the electric turbo-charger can reduce fuel consumption.
    If maximum air flow at high speed is unchanged to maintain engine power, in most cases the compressor surge line must move further to the left to provide the required increase in low engine speed air flow and boost pressure, Figure 1 [].

    Trending Topics. Turbochargers use otherwise wasted exhaust energy that would go out the tailpipe to drive a turbine wheel connected via a shaft to a compressor wheel. Sam Abuelsamid. Electrifying the turbocharger also removes the design constraints prioritizing turbine efficiency at low engine speeds to drive the compressor.

    The e-turbo as conceived by Garrett and its competitors adds the electric motor to a turbocharger in one unit. So why can't you just slap an electric blower on your conventional car? Garrett's E-Turbo keeps this basic concept but adds a small electric motor on the shaft between the two wheels, which allows two new things to happen. Today's Top Stories.

    requirement for the electric motor when it is used to reduce turbocharger lag [​]. Five Ways to Reduce Turbo Lag.

    There isn't a single solution to eliminate turbo lag, although there are a lot of strategies that can help. First, the electric motor can spool up the turbo to provide boost immediately off idle, effectively eliminating the lag between the time a driver hits.
    In turn, that energy is then used to spin up the e-turbo the next acceleration is required.

    The first inlet to the turbocharger is designed for lower engine speeds where exhaust gas flow rate is low and is therefore small in diameter. A lifetime in the car business, first engineering, now communicating. Garrett, was spun off from Honeywell in latereclaiming part of the original name it had before being acquired by the same company in

    1. There are actually two distinct types of electric boosting devices for engines that have emerged in the past several years. Typically turbocharged engines run with a lean air-fuel mixture at low boost to provide some extra power in that operating range.

    2. Zip Code. Garrett's proven world-class expertise in handling multivariable controls addresses the added complexity of introducing electrical energy into the vehicle and creating a more complex system with multiple objectives.

    3. Under conditions where supplementary power is provided to the turbocharger, turbocharger shaft speed increases and can lead to a mismatch between exhaust flow and turbine geometry that can decrease turbine efficiency as shown in Figure 2. After earning a mechanical engineering degree from GMI I spent the next 17 years working on elec
