Designed for maximum reliability
The D13 engine is built with durable components, intelligent thermal and lubrication systems, and integrated digital support—all designed to reduce service interruptions and keep trucks on the road longer.
More precise fuel delivery with reduced valvetrain load and improved emissions control
High‑pressure fuel pump
Cleaner, more consistent combustion through electronically controlled injection timing and pressure
Common rail injection
Reduced soot and NOx through advanced piston combustion geometry
14‑wave piston
Turbo (VGT)
Volvo’s variable geometry turbocharger precisely controls exhaust energy to improve engine response, enhance engine braking performance, and deliver durable, heavy‑duty reliability.
EGR Valve
An electronically controlled EGR valve provides precise exhaust flow management and position feedback, helping stabilize emissions while supporting consistent engine performance and long‑term durability.
Electric crankcase ventilation
A closed electric crankcase ventilation system separates oil mist and returns cleaned gases to the intake, preventing hydrocarbon release while reducing load on the engine’s oil system.
Variable Displacement
A variable displacement coolant pump automatically adjusts flow to engine demand, reducing parasitic losses, improving fuel efficiency, and maintaining optimal operating temperatures.
