D7E
D7E is a straight six-cylinder, four-stroke, turbocharged diesel engine with direct injection and intercooler, as well as wet
replaceable cylinder liners. The engine is equipped to meet governing legislation according to Tier 3/stage IIIA for exhaust
emissions.
The D7E engine uses a Common Rail Fuel System controlled by the engine electronic control (E-ECU) software.
The D7E uses V-ACT (Volvo Advanced Combustion Technology). Engine D7EV with ACT features split injection, optimized air
handling and turbocharger with wastegate. Electronically controlled IEGR (Internal Exhaust Gas Recirculation) reduces NO
contents and reduces emissions without the need for after-treatment of exhausts. All electronic functions in the engine are
controlled by Volvo's latest engine management system, EMS2.
The engine's serial number is stamped on the name plate, on the cylinder block's side and on the valve cover. The engine's
model designation and serial number must be indicated when ordering spare parts.
Figure 1
The cylinders are numbered in sequence, starting at the flywheel. Ignition order: 1-5-3-6-2-4. The engine's rotational
direction is counter-clockwise, seen from the flywheel.

Engine protection — Software
The function informs the operator and limits the engine's rpm and torque as well as machine speed to prevent any engine
damage. Engine shut-off takes place first when speed is below 2 km/h (1.2 mph). This makes it possible to move the
machine away from hazardous situations before engine shut-off takes place.
The function is monitored by the engine control unit E-ECU and, depending on which component is generating the alarm,
then any of the following functions is activated:
reduction of engine's torque
limitation of engine's rpm
limitation of machine speed

Engine speed (engine speed for E-ECU) — Software
This function monitors boost pressure and informs the operator if there is a system malfunction.
Engine speed is used internally in the E-ECU for engine control and as input signal for engine protection.
In case of engine speed sensor malfunction, the E-ECU uses sensor SE2703 for camshaft speed instead.

Increased engine speed — Software
The function prevents reduction of engine rpm in case of high power usage.
When operating forwards or in reverse, and engine speed > 950 rpm, the function is activated if the accelerator pedal is
released quickly or if the engine speed drops quickly.
If the engine speed is > 1150 rpm and the function is activated, the engine speed will drop normally to 1150 rpm, then after
the time delay the controlled engine speed reduction is engaged.
When the engine speed drops to "increased engine speed" 950 rpm (7), it will remain until the gear selector is moved to
Neutral position and controlled engine speed reduction takes place to idle speed.
