The durable and powerful engines provide
the heart of the Actros.

When it comes to cost-effectiveness, their low fuel consumption and high injection pressure is important. The Telligent® engine management system plays a central role in achieving this. This proven electronic engine management system adjusts the injection of fuel with extreme precision at the level of milliseconds to each driving situation. 

Reduced gas exchange losses, turbochargers with a high rate of air flow for high engine output and the use of single-cylinder air compressors with closed loop control also contribute to the low fuel consumption of the Actros.

A two- cylinder air compressor with closed-loop control is available as an option. The Actros engines demonstrate impressive durability, too.

Modifications to the engines ease the thermal load on the pistons and thus ensure that oil consumption is kept at a constantly low level. The injection nozzles are fitted with heat-insulating sleeves, which also help lower the thermal load.

In addition, these sleeves reduce the amount of soot deposited in the engine oil - which brings us to the subject of maintenance. Inlet valves and seat rings made   from more durable materials allow the valve setting intervals to be extended.
