Honda Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

That last picture: Never realised there is so much "left over" space between the tail of the bull and number 10 underneath the engine cover. Is this for cooling or aero performance?

Mandated bodywork area (thought there was a minimum amount required there) ? Having said that, the "flat" portion of the bodywork is quite small, so having the "3-D" surface is doing something.

Flat silver part is a radiator. Air intake is the top vent of 2nd photo, exit is between radiator and bodywork. Maybe it increases flow.

Looks like they've moved to a dual outlet compressor.

Orange- outlet
Blue- from intercooler
Yellow- chassis mounts for position reference
Grey line- approximate height of outlet flange center

New spec incoming, have any of you noticed Honda has no reservations giving money shots of the power unit once a new one is rumored to be around the corner.

Interesting about that gap between the exhaust and bodywork, and how it tapers down. I know what that does. :twisted:

If this keeps up Verstappen is going to know what Marquez in Moto GP has been feeling the last couple of years.

This power unit has taken a nice step forward, it's so beautifully constructed. The oil tank =D>

Exactly.

Mind sharing what that gap does godlameroso?

I think there's a single compressor outlet. It's the charge cooler outlet that splits the flow.

Why would you have a twin compressor outlet anyway ?
How much TQ does it make though?

"Reliability has been strong?" Between 4 drivers so far they used 15 ICE, 14 TC, 14 H, 14 K. And how can a driver still have three engines available to use?.

Seriously? They still have first two specs available to use during Fridays.

Same reasons they use two turbine inlets, one being: packaging. There is one intercooler per side. Feeding each individually would reduce charge pipe length, volume and weight. It could be that they simply use a wye pipe somewhere, but the photos this year show two similarly treated (two white o-rings) large-diameter (air-handling) pipes emanating from behind the oil tank, as well as individual charge cooler returns per bank. I don't think they will have positioned a wye pipe in such a space constrained area (behind the oil tank and compressor). I think the volute has two outlets.

The engine were not changed rcause they broke, they are still usable

One Toto Rosso driver is on his 5th ICE, The other is on his 4th ICE. Do you mean to says they can use other than the current one and the last one that had been replaced?.

Theoratically. Of course they wont as packaging will likely have changed with each spec.plus power gains that you throw out the door. But If push comes to shove they can use them on fridays, and even on race day should that incredibly unlikely event turn out a reality.
