The PACCAR MX-13 Euro engine 6, with a volume of 12.9 liters, uses ultra-modern injection technology with a fuel distribution ramp, a turbocharger with variable geometry and an optimized control system that provides maximum efficiency. Furthermore, to comply with the strict requirements of the ecological standard Euro 6, the engine is equipped with a recirculation system for exhaust gases in conjunction with SCR technology and an active soot filter.


The engines provide additional torque at low speeds at the highest gear for gearboxes with direct high gear and on the two highest gearboxes with high gear, which reduces the car's fuel consumption.


A six-cylinder in a row diesel engine with turbocharges and intermediate cooling. Superflowing fuel combustion due to the use of a different processing system for exhaust gases with re-cycling of OG (EGR), anti-dryer filter and selective catalytic neutralization (SCR), which ensure the content of toxic substances in emissions in the Euro 6 standard.


Advanced technologies, first-class materials and a comprehensive set of integrated functions increase the reliability and durability of the engine. Pipelines for supplying coolant and oil, low-pressure fuel pipelines and the NTVD housing are built into the cylinder block. The cylinder block is designed without lateral covers to ensure maximum stiffness and low noise. In a whole cylinder block, an intake manifold is built. The combined fuel pump and the moisture separator are installed directly on the engine to ensure the maximum simplicity of maintenance.


All Paccar MX-13 engines provide high performance in a wide range of engine speeds, as well as excellent indicators of torque at low rates. The optional powerful motor brake MX Engine Brake provides optimal controllability on protracted slopes. MX Engine Brake brake integration into the working brake system increased driving safety and reduced brake pads' wear.


A thoroughly controlled process of fuel combustion, in combination with other technologies aimed at achieving ultra-low emissions according to the Euro 6 standard, helps to increase fuel efficiency.


The amount of fuel entering the total fuel distribution ramp is measured by the intellectual dosing system, which provides optimal efficiency by compressing only the required fuel mixture. This reduces hydraulic losses to a minimum.



To comply with the strict requirements of Euro 6 in the content of toxic substances in the exhaust gases, DAF uses several technologies for additional processing of the exhaust gases, such as the catalytic neutralizer of the SCR and an active soot filter. The correct composition of the mixture of the exhaust gases contributes to the optimum temperature in the filter necessary for regenerating the collected soot particles.


The exhaust manifold and the most critical parts of the exhaust gas production system are isolated for maximum use of passive regeneration. In addition, higher temperatures positively affect the operation of the CCR catalytic neutralizer, which increases efficiency and reduces ADBLUE fluid consumption.




Paccar MX-13 engines are also available in EURO 5 and Euro 3. The main difference between these versions is the system of additional processing of the exhaust gases. Compared to the Euro 6 version, there is no DOC (diesel catalytic neutralizer) and DPF on the Euro 5 version. That is, there is no active soot filter on cars of the Euro 5 version. The Euro 3 version is not equipped with a system of additional processing of exhaust gases and is supplied only with a silencer to reduce the noise level. Three versions of engines do not have significant differences in working indicators.
