Poll: Next big "green" powertrain
What will be the next big "green" powertrain in the U.S.?
Nissan Murano Diesel Launched in Europe
Nissan announced its Murano crossover will be available with a diesel engine option starting this fall.It is an enhanced version of the 2.5dCi four cylinder engine, giving the Murano 187hp and 332lb ft of torque.
The changes made to the engine include a new direct injection system which operates at 2000 bar, up from 1800 bar. This increase in pressure means the fuel spray is atomized to an even finer degree resulting in more complete combustion.
A new cylinder head with parallel ports increases the swirl efficiency of the combustion process, smoothing the intake and exhaust flow, while a new variable nozzle turbo (VNT) with electric control rather than the previous hydraulic system for quicker responses has also been adopted.
The engine is offered as a single powertrain with a six-speed automatic gearbox, providing smooth, discreet gear-shifts to guarantee seamless, effortless progress. With a high degree of lock-up, engine responsiveness is keen and its shift logic has been programmed to make the most of the high-torque engine characteristics, but also to optimize the fuel economy.
Furthermore, the gearbox is equipped with ASC (Adaptive Shift Control), which will modify shift patterns according to the prevailing driving style, tailoring the gearbox to hold on to a lower gear during a descent for added engine braking, for example.
Power is transmitted to the road via Nissan’s advanced ALL MODE 4x4-i technology, which sends power to the rear-wheels when a loss of stability or traction is detected.
