[QUOTE="docrayboy, post: 514247, member: 19175"] Even the diesel engines are getting twin scroll technology.... [I]New 3-liter diesel. With the further development of BMW TwinPower Turbo technology, additional dynamics and efficiency potentials have also been made accessible for use on in-line six-cylinder diesel engines. The new 3-liter diesel power unit features a further optimization of internal friction coefficients, weight and fuel injection. Maximum power output has been increased by 10 kW to 190 kW/258 bhp. Maximum torque is now 560 N·m (413 lb-ft)—20 N·m more—and is available at 1,500 rpm. Apart from modified air supply with shortened ducts, the response characteristics of the new six-cylinder diesel engine also benefits from a weight-optimized crankshaft. An optimized injection process contributes additionally towards an increase in output and torque. Common Rail injection, the solenoid valve injectors of which operate at a maximum pressure of 1,800 bar, ensures, inter alia, by means of a recalibrated pre-injection system even more efficient combustion, spontaneous power development and enhanced acoustic characteristics of the diesel engine. The turbocharger with variable intake geometry has been further optimized and now boasts even better stability. Simultaneously, the weight of the turbine wheel was reduced. The spontaneous response of the supercharger associated with this boosts power delivery at low engine speeds. The new diesel engine featured in the new BMW 530d xDrive facilitates acceleration from 0 to 100 km/h in 6.1 seconds. Average fuel consumption in the EU test cycle is 5.7 liters/100 km (41 mpg US), while the CO2 emission level has been reduced to 150 grams per kilometer. In terms of its basic constructional features, including the arrangement of the ancillary components and the belt drive, the new in-line six-cylinder is virtually identical to the current BMW four-cylinder diesel power units.[/I] [URL="http://www.greencarcongress.com/2011/04/bmw-launches-first-4-cylinder-member-of-efficient-dynamics-engine-family.html"]http://www.greencarcongress.com/2011/04/bmw-launches-first-4-cylinder-member-of-efficient-dynamics-engine-family.html[/URL] [/QUOTE]
