Cooling the Harvester gas engine / heat management

[BradScout]

Wondering how the Harvester gas engine is going to be cooled.
It may not be possible while sitting still due to Carbon Monoxide and heat buildup. Ya know there is that one dude that will try to run Harvester in their garage.

Here's the oil cooler for the Harvester engine -- from these photos of the underbody: https://www.scoutevforum.com/electric-solid-rear-axle-ebeam-rear-axle-underbody-photos-analysis/

A good question with a planned rear-mounted engine. My bias initially thinks of current conventional water-cooled IC engines, but this is VW at heart, maybe a return to air-cooled like the older Beetles?

Thanks for the info.

Couple questions I have in mind after seeing the photo. Does anyone know if the under body is protected by a “shield” from off road hazards? Also, whats the expected maintenance of EV + Range Gas Extender?

A full EV doesn’t have to worry about oil change and everything else a gas engine would need. So I’m curious how the engineering/mechanics work with Harvester.

Yea here's the underbody shield / skid plates on the revealed Scouts

I’ve read that the Harvester is a generator, designed to charge the EV battery, and that it can add 150 miles of range on top of 350 miles of range supplied by the battery pack. OK, sounds good!

If the EREV models average ~3 miles per kWh, then the generator would need to produce 50kWh to add 150 miles of range (leaving efficiency losses aside). So you head out, traveling 60mph. In less than 6 hours your battery would be empty, but thankfully the generator kicked in at the 100 mile mark, and ran for ~7 hours generating 50kWh. This scenario suggests a 7kW generator …+/-12hp. It will be interesting to learn how heat is managed, especially if it can run while parked. Hoping that sharper and better schooled minds can fine tune these assumptions and shed some light on how Scout has solved this.

They said in the presentation that the harvester will have a smaller battery to account for the engine and gas tank. No one knows what the percent split will be though. Honestly if it’s just there as an emergency backup for an extra 150 miles and not an option for using on road trips as your primary power I don’t think I’ll be getting one. Charging on road trips is a pain (I say this as a first year model 3 owner, which has a great charging network) and it’s even more difficult if you are towing.

I’m wondering if that 150 miles extra is replenishable, like once you hit 500 miles, are you done till you can find a place to plug in? Or can you refill the gas tank and wait for it to recharge itself for another 150 miles?
