"Mercedes new superengine"
Can someone who knows a thing or two about German language translate this? From Google translate I get that they use some interesting "trick" and that one other engine manufacturer is playing with the same trick.
Here so little fuel is injected into the combustion chamber, the mixture would not burn with a normal spark. Therefore, the pre-chamber is then also enriched with an extremely small amount fuel, which is ignited by a spark plug in the prechamber.
Result: The hot gas wisps ignite the lean mixture in the rest of the cylinder. In particular in the partial load range Mercedes can thus save fuel which can be used in full throttle for more power.
I will try.
"The trick: a double injection together with a pre-chamber ignition.
Is this case only little fuel is injected into the (main) chamber, which would not ignite the mix using a standard spark. Therefore, the pre-chamber gets enriched with another extremely small quantity of fuel, but which in turn gets ignited by a spark plug in the pre-chamber.
The result: the hot gas strands inflame the meagre mix in the rest of the cylinder.
Especially under partial load, Mercedes may save fuel, which they may then spend at full throttle passages for more power."
