Power Vs. Torque Question
I appreciate that torque is effectively the turning force of the engine which is generated just after the fuel/air mix is detonated, but what I don't understand is what is going on with all the current diesels you can buy, E.g. the VW V10 diesel.
Why is it that diesel cars are able to produce so much more torque than their petrol counterparts and still have lower emissions and less bhp? Could somebody also please explain how it is possible to adjust the torque curves by an engine so that you have bucket-fulls of torque lower down the rev-range to make a car more usable, but then still have a bhp peak much higher in the rev range?
Your help with this is much appreciated..
