The modern, long - stroke engine with the internal code 4P10 features two robust chain - driven overhead camshafts; four valves per cylinder; an exhaust gas turbocharger with variable turbine geometry; common rail injection system; and
piezo injectors for precise metering of fuel.
Not exact matches
It may be caused by the failed
piezo injectors, which were replaced not
for once
for the time of manufacturing the N63B44.
To reduce exhaust emissions, use is made of tried - and - tested
piezo injectors with a good mixture preparation, a further - improved combustion chamber and a particulate filter
for petrol engines.
Its injection system has the same type of
piezo - electric fuel
injectors as the D5, but tailored
for the smaller engine.
The 70 Series» intercooled V8 will be upgraded to meet the stricter Euro 5 emissions standard required
for all new vehicles from November 2016, with more responsive
piezo injectors joining common - rail direct - injection.
Thanks to their ability to switch within milliseconds, the
piezo injectors also allow the multiple injection that is also of benefit
for lean - burn operation, thus playing a crucial role in achieving the engine's exemplary consumption figures.
These engines feature latest - generation common - rail direct injection, fast
piezo - electric
injectors, improved exhaust gas recirculation and an innovative twin turbocharger, making
for fast responsiveness and good performance characteristics.
A new - type
piezo injector is another essential element in attaining the ambitious performance / efficiency / emissions goals with the necessary long - term durability: A «stack» of
piezo crystals reacts lightning - fast to impulses from the engine electronics, governing the
injector needle's opening stroke and duration
for ultra-precise control of fuel quantity.
It features
piezo - electric
injectors for more precise injection, and the common rail system gives greater flexibility.
Boost is provided by a variable - vane turbocharger that works in combination with the latest
piezo injector technology
for more efficient blending of fuel and air.
The engine benefits from higher fuel injection pressure of 2,000 bar and more efficient
piezo injectors with smaller holes
for a finer spray.
