Engine D13A440, EU4SCR / EU5SCR
Fact Sheet The D13A440 is a 440 hp 12.8-litre in-line, six-cylinder diesel engine equipped with an overhead camshaft, four valves per cylinder and unit injectors. The engine meets the EU exhaust emissions requirements according to Euro 4 and Euro 5 (incentive) standards. The D13A440 is designed for heavy long-haul and construction operations. It is based on a robust and dependable design with an overhead camshaft, four valves per cylinder and precisely controlled electronic fuel injection. The engine is designed for low fuel consumption, good driving properties and high availability. The timing mechanism is located at the rear of the engine, which results in less vibration and permits the fitting of a rear-mounted power take-off. The D13A440 is a low-emission engine as regards both exhaust gases and noise level. Owing to after-treatment of exhaust emissions with SCR (Selective Catalytic Reduction) technology, the engine is approved to the EU’s Euro 4 and Euro 5 (incentive) standards. The D13A440 is available with VEB+ (Volvo Engine Brake) as an option. This system provides extremely high braking effect, further improving safety and reducing wear on the wheel brakes. The D13A440 is characterised by the following product features: • Maximum torque within a broad rev range. • Fuel-efficient. • Electronic engine management (EMS). • Low-emission variants, Euro 4 and Euro 5 (incentive) • Extremely high engine braking effect with VEB+ (option). • Rear-mounted power take-off with high power output (option). • Closed crankcase ventilation (option).

Engine D13A440, EU4SCR / EU5SCR
Fact Sheet Efficient combustion for excellent driveability The D13A is equipped with unit injectors that provide high injection pressure. The combustion chamber and inlet manifold are designed for optimum combustion. The gas-fill ratio is extremely high, which contributes to the high efficiency. This design creates a fuel-efficient engine with high power and immense torque within a broad rev range. This gives the D13A excellent driveability. Meets emissions requirements with SCR technology In order to supplement optimum combustion technique the exhaust gases are after-treated by SCR technology (Selective Catalytic Reduction). In this process, an additive (AdBlue) is injected into the exhaust gases before they pass through an SCR catalytic converter. There the AdBlue reacts with the nitrogen oxides in a process that significantly reduces emissions. With this system, the D13A is approved to EU emissions standards according to Euro 4 and Euro 5 (incentive).
AdBlue tank located beside the regular diesel tank.
Vibration damper cuts noise emissions The D13A meets the relevant noise emission requirements without needing advanced encapsulation. The crankshaft and camshaft feature hydraulic vibration dampers which minimise noise and vibrations. The electronic injection is also used to further dampen noise at low revs. This makes the D13A a quiet engine which idles very softly.
Closed crankcase ventilation The D13A is available with optional close crankcase ventilation. The system is known as CCV-C (Crank Case Ventilation – Closed). The crankcase gases in the valve cover are returned to the turbocharger via an oil separator with a centrifuge. The oil mist is separated in the maintenance-free centrifuge system, so there is no need for filter replacements. Owing to the recycled crankcase gases, this system promotes an extremely clean and environmentally compatible engine.
VEB+ engine brake provides extremely high braking effect The D13A is available with the VEB+ (Volvo Engine Brake+) auxiliary brake. Its design is based on interaction between the exhaust brake governor and Volvo’s patented compression brake. Using a specially designed camshaft in combination with rocker arms, the gas pressure in the cylinders is regulated to provide maximum braking power. VEB+ provides extremely high braking effect – up to 375 kW. A powerful engine brake boosts safety at the same time as wheel brake wear is reduced. In combination with cruise control, VEB+ creates the necessary preconditions for higher average speed and better fuel economy. Electronic engine management integrated in the vehicle electronic system
Timing and power take-off at the rear The engine timing mechanism is located at the rear and drives the power steering pump, oil pump, fuel feed pump and air compressor. It is a compact, quiet and thoroughly sealed design that saves weight. With the timing at the rear, the engine’s cooling is also improved since the flow of incoming cooling air is not obstructed. The D13A can be equipped with a power take-off designed for propeller shaft operation or direct-mounted hydraulic pumps. PTO mounting on the engine’s flywheel results in a dependable design and permits high torque levels, up to 1000 Nm in continuous operation.
The D13A engine is equipped with Volvo EMS (Engine Management System) which means that the engine’s functions are operated and controlled entirely electronically. EMS promotes efficient engine management and advanced scope for diagnostics and fault-tracing. The engine control unit is connected to the vehicle electronic system’s data links and the information is presented via an easy to read display in the instrument panel.
