The New V6 Engine From Mercedes-Benz

Tumble flaps in the intake ducts for an optimal combustion process

Mercedes engineers have configured and optimised all the air ducting components with the help of sophisticated airflow simulations. The magnesium intake module has likewise been optimised in terms of flow characteristics. The length of the intake manifold can be varied according to the engine speed to achieve the best possible torque and output. From 1500 rpm the new V6 already develops approx. 87 per cent of its maximum torque of 350 Nm.

The intake ducts are equipped with newly developed tumble flaps which improve the intake process and combustion of the fuel-air mixture. These pivot open under partial load, increasing the turbulence of the gas flow in the combustion chambers. Under higher engine loads the tumble flaps are completely recessed into the intake manifold.

Thanks to the use of these innovative tumble flaps, the fuel consumption of the V6 engine is reduced by up to 0.2 litres per 100 kilometres depending on engine speed – with a significant improvement in smoothness.

An intelligent heat management system also contributes to fuel economy. Mercedes engineers have developed a new, electronic map-controlled thermostat which is active in all engine operating situations. It directs the heat flows inside the powerplant in such a way that the engine oil and coolant are always at the best possible temperatures.

Exhaust emissions below the future EU 4 limits

By virtue of variable camshaft adjustment, tumble flaps in the intake ducts, internal exhaust gas recirculation, secondary air injection and other features, the exhaust emissions of the new Mercedes six-cylinder engine are already at a very low level during the combustion process.
