Marine engine technology transfer to F1

[shelly]

2014 v6 turbo engine seem to share some technology with bigger marine engines (turbo compounding, turbo harvesting, exhaust scrubbers...) I was wondering how close this link can be - does somebody have some information about this?

Don't know specifically. But technology transfer from consumer to motorsport certainly isn't uncommon.

I cannot see any reason to use a reciprocating internal combustion engine in any efficient modern marine propulsion unit.

I do not know much about marine propulsion, but I have seen that the turbo manufacturers (Borg wariner, honeywell etc) are also suppliere for big turbo marine piston engines, and that they offer for this field turbos that can either charge a battery or be assisted by an electric motor. This technology has not yet been applied to cars as far as I know.

Also, marine engine makers have developed (mainly for emissions control) exhaust management systems (like the exhaust scrubber) which have been applied to f1 cars from 2011 onwards, in the form of Helmoltz resonators and so on.

So it seems to me that a partnership between f1 engine makers and marine engine makers is a reasonable option, so that the f1 maker can get the knowledge quickly

Yet they're quite common...

what would you use instead?

His magic gear box its so good it doesn't need a motor

It doesn't even need a car. It has the "world's best seat" casted into the casing and little wheels built purely out of recovered energy.

The most efficient marine propulsion units in use are massive 2-stroke diesel engines. Every large ocean going tanker or container ship uses a recip engine with a direct drive propeller.

While some of the basic principles are the same between current F1 engines and large marine engines, such as turbocharging and turbocompounding, the implementation is far different.

I really don't see what exhaust scrubbers and Helmholtz resonators has to do with each other? F1 engines doesn't use scrubbers.

Subaru or Mitsubishi(on of the two) has it on their new impreza/Evo.

F1 engines doesn't use scrubbers.

I always see plenty of scrubbers in the paddock
