Engine and emissions technology

Economical. Powerful. Environmentally friendly.

The Unimog implement carrier is equipped with the most modern Mercedes-Benz BlueTec 6 technology. Tested in large-scale series production, the Euro VI engine generation sets new standards for its class and takes no half-measures where conserving the environment, economic efficiency and top performance are concerned. The 4 and 6-cylinder engines ranging from 115 to 220 kW are especially easy to maintain, economical, smooth-running and powerful. They have high torque of up to 1200 Nm as well as good results for exhaust emissions, consumption and power-to-weight ratios. 4-valve technology and common rail injection up to 2400 bar further increase efficiency.

The engines are also used for braking: the strong premium engine brake reduces mechanical wear and tear on the brakes and makes a great contribution to economic efficiency.

The exhaust gas aftertreatment system uses BlueTec 6 technology which has already proven its worth in daily use over many millions of kilometres in our heavy-duty mass-production engines. In the exhaust gas aftertreatment unit, the SCR catalytic converter reduces the nitrogen oxides to a minimum. And the diesel particulate filter prevents almost any soot particles from escaping.

With the U 423, U 429 and U 529 models, the Unimog implement carrier is available with modern Mercedes-Benz engines (OM 934/OM 936, 4 and 6-cylinder) in Euro V and Euromot IV versions. In these versions, no diesel particulate filter, camshaft adjustment and HC metering is used. As a result, such things as the maintenance and life cycle costs are reduced. The general model variant of the three vehicle types corresponds to the basic concept of the current implement carrier model series.

Combined with emissions level Tier4f, approval as an agricultural tractor is possible. Providing the highest economic efficiency in these applications. The Unimog fulfils the emissions standards applicable to tractors.
