These engines include a 2.4 - liter gasoline, a 2.5 - liter turbodiesel, and a new 2.4 - liter turbodiesel with
electronic valve timing.
Their Multiair engines use
electronic valve control which dramatically improve torque and horsepower, while reducing fuel consumption as much as 15 %.
Both feature BMW's exclusive Valvetronic
electronic valve actuation and Double VANOS variable valve timing, which contribute to better - than - expected fuel efficiency for such performance - oriented vehicles.
The ECU (computer), may adjust the fuel / air mix by acting over
other electronic valves and mainly depending on the exhaust gases «quality», among other readings it uses.
Each Öhlins shock absorber is fitted with a
new electronic valve, installed for the first time on any road car in conjunction with Öhlins shock absorbers.
Direct fuel injection, continuously
variable electronic valve timing, and a 1.7 - liter supercharger provide the perfect balance between performance and efficiency.
The engine, a 3.5 - liter overhead - cam V - 6 with
electronic valve control, will produce between 260 and 280 horsepower and is teamed with a standard six - speed manual transmission.
Base DX model has 135 - horsepower, 2.3 - liter four - cylinder engine; EX and LX models have 150 - horsepower, 2.3 - liter with
electronic valve timing.
There's a two - stage active exhaust
with electronic valves to deliver a meaty exhaust note that fully opens above 3000rpm that even manages to crackle on the overrun.
An evolution of the Swedish company's electronic damping technology,
an electronic valve is positioned within the damper and constantly monitors both driver inputs and the road surface conditions to adjust the damping rate accordingly.
The engine uses sequential multipoint fuel injection, handled by
an electronic valve timing control system that varies the camshaft phase and intake valve timing according to engine rpm and load.
The high - pressure pump is a cam - driven mechanical pump with a single piston and
an electronic valve that controls how much fuel is routed into the fuel rails to the injectors.
By pressing the exhaust sound control switch prior to engine start, this will close
the electronic valve within the exhaust system for more quiet operation at engine startup and continue for a brief time while the vehicle is driven with the engine running at low rpms.
There is a 10 dB difference between having
the electronic valve within the exhaust system closed and opened — a substantial difference in volumetric sound quality to the human ear.
Electronic valves have a built - in sensor to release water when they detect your pet's presence, while mechanical lick valves are triggered by your dog's licking.
