The multiple
award-winning petrol and diesel engines with BMW Twin Power Turbo technology
are among the innovations from BMW Efficient Dynamics. They combine the latest
fuel injection systems, fully-variable performance control and innovative
turbocharger technology.
BMW Twin Power Turbo petrol engines.
How does it work.
The technology concept
of the BMW TwinPower Turbo petrol engines is applied throughout the series.
Innovative turbocharger technology and Double-Vanos increase performance and
ensure spontaneous response even at low speeds. The petrol injection system
High Precision Injection and the fully-variable valve control Valvetronic lower
consumption
Three components ensure
that the BMW TwinPower Turbo petrol engines are capable of achieving the unique
relationship between performance and consumption.
The innovative valve
control Valvetronic (= variable valve and electronic) with Double-Vanos varies
the hub of the inlet valve fully. This allows the engine to develop optimum
power with less consumption. The Valvetronic also improves the mixture preparation
and lowers fuel consumption by up to 10% (BMW internally-determined value based
on ECE driving cycle). An additional effect is improved response.
Double-Vanos refers to
the double variable camshaft control. This system controls the engine
performance all across the speed range and enables lower consumption and fewer
emissions at any speed.
High Precision Injection
with its particularly accurate fuel dosage ensures extraordinarily efficient
and clean combustion. This derives the maximum amount of energy from every drop
of fuel.
Innovative turbocharging
technology increases the engine’s power and puts it on par with much larger
engines – and all this with fewer components, reduced inner friction and low
weight. And thus with lower consumption and emissions.
Together with the other
innovations by BMW Efficient Dynamics this allowed a fuel saving of up to 15%,
for example, in the BMW 328i Sedan in relation to its predecessor the BMW 325i.
