DAF’s efforts to create heavy-duty diesel engines utilizing the most recent design and manufacturing techniques have resulted in all DAF MX engines. The DAF MX 265’s unique driving conditions are guaranteed by its high performance and substantial torque, while its compact design and the newest materials enable weight reduction while maintaining maximum service life.
The DAF MX 265 series’ six-cylinder, in-line, 24-valve, turbocharged, intercooled diesel engines have a 12.9-liter capacity. equipped with the SCR (Selective Catalytic Reduction) system, which enables the exhaust gases to reach a harmful emission level that satisfies the Euro 4 environmental standard.
The ability to install an automated shutdown system is one of DAF MX engines’ unique features. It operates as follows: the engine is automatically turned off when the vehicle is idle for longer than five minutes.
Because of the DAF MX 265 engines’ high torque (between 1775 and 2500 Nm) and low speed (between 1000 and 1410 rpm), a gearbox with fewer speeds can be used, giving the motor its maximum performance potential. CF85 and XF105 series DAF trucks have these engine modifications installed.

The engine block has completely insulated wiring for the first time in the industry. This guarantees that the connectors and wires are firmly attached to the engine block. High dependability and durability are ensured by well-protected wiring.
The new MX engine brake was optimized. It now generates 360 kW of braking force. The best part is that, starting at 1500 rpm, three-quarters of that power is accessible at low revs. The controls function more smoothly and are optimized.
A high volume synthetic cast sump is a feature of the new MX 265 engine. Both vibration and engine noise are decreased by its new form. To maximize uptime and reduce maintenance costs, the new engine has a combined fuel filter, heater, and water separator.
The sophisticated unit offers the required power indicators and a smooth ride. Fuel consumption is greatly reduced by an improved injection system, a special exhaust manifold (fully insulated), and new pistons. Both the turbine speed and the boost pressure rise as a result. As a result, the turbine’s rotational speed can be increased without the volume of exhaust gases increasing noticeably. It is necessary to cool the air that emerges from the compressor. An air cooler, known as an intercooler, is incorporated into the engine design to accomplish this.

The first business in the automotive sector to employ thermal encapsulation for both an exhaust system and a turbocharger is DAF. By boosting turbo efficiency and improving combustion, this leads to even more “airy” handling. The MX 265 engine has been modified to cut CO2 emissions and fuel usage by 3%.
The truck’s power plant has a 150,000 km service interval when using synthetic oils and a 90,000 km service interval when using mineral oils. This amount is lowered to 60,000 kilometers of run under Russian conditions.
