The Volvo D16E660 is a six-cylinder, 16.1-liter in-line diesel engine with an intercooler and turbocharger. 660 horsepower from the engine The engine satisfies the Euro 4 standard’s EU emission requirements.

The D16E660 is made to transport heavy loads. With an overhead camshaft, four valves per cylinder, and a precise electronic fuel injection system, it is built on a sturdy and dependable design. The D16E660 engine’s extremely high power allows it to produce remarkable torque over a broad rpm range, ensuring excellent handling characteristics even in hilly terrain. Excellent traction performance is also provided by the high torque at low revs. Low noise and low emissions characterize the D16E 660 engine. The engine’s Selective Catalytic Reduction (SCR) exhaust gas treatment makes it Euro 4 compliant. A Volvo engine brake (VEB +) is another option for the Volvo D16E 660. This design increases safety and lessens wear on the service braking system by providing a very high braking force.

High pressure injection is made possible by the unit injectors installed in the D16E engine. Optimal combustion is ensured by the intake manifold and combustion chamber’s unique design. High efficiency is a result of the extremely high gas filling rate. Even in challenging transport conditions, the D16E offers exceptional driving performance thanks to its economical engine, which produces high power and torque over a broad rpm range.
Selective Catalytic Reduction (SCR) technology is used to treat the exhaust gases in addition to the ideal combustion process. Prior to the exhaust gases entering the SCR catalytic converter, AdBlue is injected into it. AdBlue dramatically lowers emissions by reacting with nitrogen oxides. The D16E engine is approved in accordance with the Euro 4 emission standard because of this system.
