Clearly that cannot be true.

If you start with 150Kg of fuel as opposed to 100Kg you are creating 33% more heat. The job the engine designer has is to minimise this loss. Turbocharging increases engine efficiency because it captures some of the waste heat and turns that heat into energy and in Anonymoushttps://www.blogger.com/profile/11130230696626296315noreply@blogger.comtag:blogger.com,1999:blog-2239944414177437471.post-13740225954619950082014-03-19T11:28:16.061+00:002014-03-19T11:28:16.061+00:00Obviously the conversation of energy applies but n...Obviously the conversation of energy applies but now an F1 car is conserving more energy.

The principle of conservation of energy means one cannot create more energy, or heat from less fuel, all things being equal. Given that the efficiency of the PU has increased from around 30% to 40% means that less fuel is burned per kw output. Electrical energy is part of that 10% gap, so you cannot count it twice!

The turbo compresses it and the outlet is the thing, that either directs all of it into one sidepod or splits it (can be done with two outlets in a 180° relation to each other on the housing) to be used with two intercoolers.

They're trying to attain more power at less revs with a 1.6 V6 rather than the 2.4 V8.
