Piezo-electric injectors

Our main pages on this subject:

1.	Optimize Performance
	Using technologies such as turbocharging, the same performance can be obtained from a smaller engine, which is more efficient and emits less greenhouse gas.Piezo-electric injectors. Piezo-electric injectors under electronic control optimize engine efficiency by making very precise adjustments in the amount of fuel injected..

2.	Koleos Concept : a car that gets you away from it all
	Its 2.0dCi engine makes use of state-of-the-art diesel engine technology, like piezoelectric injectors, 1600 - bar common rail injection, and variable geometry turbochargers....

3.	2.0 dCi (M9R)
	Maximum torque is reached rapidly, providing smooth dynamic performance from the lowest engine speeds through to the highest, thanks to : a water-cooled variable-nozzle turbocharger, for greater efficiency at high speeds and dynamic acceleration at low speeds (in overtaking, for example), particularly well designed internal aerodynamics to improve engine efficiency, a new-generation common-rail system (1,600 bars) to improve combustion quality, piezo-electric injectors that optimize fuel use and reduce pollutant emissions....
