Power and torque versus rpm graph
The engine has a particularly wide torque range, which means that it can run smoothly at economical rpm and with minimal gear changes. The engine has excellent torque at low revs for quick accelerator response and smoother driving. One of the reasons for the exceptional handling is fuel injection using common rail technology. Fuel is injected through one high pressure tube. The injection pressure and injection period are electronically controlled, which ensures accurate measurement and excellent atomization of the fuel during injection into the combustion chamber. The control instantly adjusts the injection parameters to the current operating conditions. The ability to inject fuel after the main shot significantly increases flexibility.
