The D7E240 is a turbocharged, intercooled, 7.2-liter in-line diesel engine with six cylinders. The engine produces 240 horsepower and 920 Nm of torque. The Euro 4 emission standard is met by it.
The engine has a single cylinder head and a camshaft in the middle that uses pushers to regulate the four valves in each cylinder. Electronic control is used to operate the engine. Fuel injection is handled by the Common Rail system. The engine satisfies the Euro 4 emission standard when used in conjunction with the Selective Catalytic Reduction (SCR) system.

Power and torque versus rpm graph
The engine can run smoothly at economical rpm and with few gear changes because of its exceptionally broad torque range. Excellent torque at low revs allows for smoother driving and rapid accelerator response. Fuel injection using common rail technology is one of the factors contributing to the outstanding handling. One high-pressure tube is used to inject fuel. Accurate measurement and superior fuel atomization during injection into the combustion chamber are guaranteed by the electronic control of the injection pressure and injection duration. The injection parameters are instantly modified by the control to reflect the current operating conditions. Flexibility is greatly increased by the ability to inject fuel after the main shot.
