The DAF MX 340 engine was developed for a number of reasons, including compliance with the new environmental standard Euro 5. Naturally, the developers aimed to create an extremely dependable and long-lasting engine. Additionally, it provides various torque values for improved driving comfort. The MX 340 blends clever innovation with tried-and-true cutting-edge technology.
The timing gear drive, which is situated on the flywheel side at the back of the engine, is one of its unique features. As a result, every gear-driven attachment is situated at the back of the engine.
The new pistons used in the MX 340 engine have better thermal characteristics and require less cooling. This indicates that for optimal performance and reduced frictional losses, a smaller fuel pump is adequate. Both the engine management system and the injection angles have been optimized concurrently.

The dependability and durability of assemblies and parts are increased by cutting-edge technologies, premium materials, and extensive function integration. The cylinder block incorporates the injection pump housing, low pressure fuel lines, and water and oil supply lines. For optimal stiffness and minimal noise, the cylinder block is made without side covers. The intake manifold bore is part of the one-piece cylinder head. A single oil block now houses the oil filter, oil thermostat, and oil cooler.
By saving fuel, intelligent injection lowers the concentration of CO and other harmful substances. Second, SCR (Selective Catalytic Reduction) technology is a feature of the 12.9-liter MX 340 diesel engines. This is simply exhaust gas afterburning. Third, the DeNOx catalytic converter improves the purification process.
The MX340 engine’s newly designed features increase service intervals to 90,000 kilometers.
Poly V-belt drive:
- Low Power Consumption
- Combined Steering Pump
- and Smart Air Control (SAC) Equipment Auxiliary Air Compressor
Retarder brake:
- Electrically controlled exhaust gas butterfly valve
MX Engine Brake:
- integrated compression brake;
- intelligent, cooled, electronically controlled actuator;
- brake power management using VTG and BPV;
The interval between maintenance can be extended by more than 1.5 times if a centrifugal filter is installed and synthetic oil is used to cool and lubricate the motor.
Explanation of markings DAF MX 340
| MX | 12.9 liter engine family |
| 340 | Engine power, kW – 340 |
With a high braking power of 210 kW at 1500 rpm and 310 kW at maximum engine speed, the engine has a decompression engine brake built into the rocker arm. DAF trucks’ general braking system incorporates the engine brake, greatly increasing driving safety.
