The higher - powered S model
uses variable turbine geometry, a technology that has filtered down from the 911 Turbo.
Not exact matches
It's based on the 3.8 - liter unit
used in the 911 Turbo S but gets larger turbochargers (with Porsche's
variable turbine geometry) capable of providing up to 22.5 psi of boost.
The bigger engine
uses a turbocharger with
variable turbine geometry.
The 740Ld will be powered by a 3.0 - liter inline - six diesel engine with a single turbocharger
using variable vane
turbine technology, making 255 hp and 413 lb - ft of torque, and will be coupled exclusively with BMW's xDrive all - wheel drive system.
In the S - model, Porsche also
uses a turbocharger with
variable turbine geometry.
Porsche is still the only manufacturer to
use turbochargers with
variable turbine geometry in gasoline engines.
A single - stage turbocharger with
variable nozzle
turbines is
used in the E 200 CDIBlueEFFICIENCY model.
The lightweight aluminium engines
use common - rail direct injection and a turbocharger with
variable turbine geometry.
This is an all new engine, and also
uses BMW's TwinPower Turbo technology, or basically
variable turbine geometry which allows the engine to put out slightly higher power (about 7 - 8 bhp more), but still reduces consumption (and emissions) by 17 % according to manufacturer data.
Wind power is not quite the same as just wind speed, so we took the
variables that are calculated directly by the global climate models and
used an industry wind
turbine power curve as something of a translation device.
Subsequent laboratory experiments
using volunteers working for SERI (rather than wind
turbine noise sensitised residents) reproduced the sound energy and the
variable effects on those exposed.
Surplus wind power can be stored as hydrogen and
used in fuel cells or gas
turbines to generate electricity, leveling supply when winds are
variable.
Compact, Cost - Effective, And Consistent What Rashidi's design does have going for it is its compact size, cost - effectiveness, and ability to generate power consistently in an urban environment where wind speeds can be too
variable and turbulent to make traditional
turbines truly effective, as TreeHugger Mat wrote in a previous article about
using the technology on city roofs.
Wind energy: Projecting electricity output at a wind farm is extraordinarily challenging as it involves predicting
variable gusts and complex wind eddies at the height of
turbines, which are hundreds of feet above the sensors
used for weather forecasting.
