YouTube's recommendation algorithm offered me this yesterday, just finished watching it. Quite interesting throughout, I thought.

Some subsequent vids by The Workshop suggest/claim that it's just a money making scam, fairly convincingly: NOTE: NSFW/family - sweary

If trickling down into the car market it needs to be a quick trickle before Petrol & Diesel cars sales are banned in the EU & UK.

I personally think that ban may not be able to happen as early as hoped, but yes.

Agreed, but how long after COP26 in November will the Government's wait before announcing the suspension of the bans,?     140bhp /  260Nm of power is enough to move 8 people around in a vehicle at up to 80 mph and that can be done in EV,s or ICE hybrid vehicles. Even ones with 3 cylinder low emission liquid fuel generators.  

If inline fours can be made better in the meantime, for those that opt for such things, we should do it though, right? 

 

I thought I'd seen the bit about secondary imbalance being solved before, and yes, Nissan/Infiniti had a solution first, using a novel piston to crankshaft linkage that that cancels secondary imbalance.

 

Plus it does variable compression ratio too....

Thanks, hadn't come across that.  I guess the one I've linked must be a little different, but we'll have to wait and see.

My 1984 2.6 litre straight 4 cylinder Mitsubishi Shogun had a balance shaft, it was a very smooth torquey and responsive engine.

Lighter engines, lighter gearboxes with more ratios (10 or 11 from VW) or CVT and lighter vehicles that go through the air more efficiently was all that was planned for the past decades.

It came to nothing really just like VW's billions that was spent getting ready to produce the great new thing which was Diesel Hybrids which was going to be the trickle down from Endurance Car Racing.

 

Now the big plan is to move away from the fossil fuels and instead get Earth Minerals from this Planet on land or under the oceans or from outer space.

 

Stuff the RoW as long as those living in countries that are Super Powers can get around.

That Infiniti/Nissan solution looks expensive, but hats off to whoever imagined that mechanism.

Massive thread on a boating forum from a year ago here: ALFADAN 654hp outboards - Page 8 - The Hull Truth - Boating and Fishing Forum

CEO 'wades' in... 

Perhaps this is why many manufacturers went for variable valve timing

There are a fair number of sceptics on that boating forum, so it may be that this is all made up - like VW's EA189 "Clean Diesel", but I'm going to keep an open mind for now.

Maybe not for open seas and oceans, but for inland waters and harbours, marinas and low emission zones through villages, towns and cities it will be the way to go.

You can have Solar & Wind & wave energy generation providing energy to charging stations hubs and their storage batteries rather than road or sea  tankers providing marine fuels or petrol.

Man! You're absolutely determined to not let this discussion be about inline 4 pot engines, eh Root?  

There's an EV subforum, remember? If I want to read about EV tech, I'll go there.

Carry on discussing something you want to, i am all ears.

4 pot engines will be here for a long time into the future as obviously there is much more to come from them. 

Just do not make any investments in them with your own cash money.

 

PS

This is General Automotive Chat,

so we are on engines, car, buses, boats, trains and planes maybe with any means of propulsion.

I have no plans to, but appreciate the concern.

 

Hopefully before any European Governments impose bans on the sale of liquid fuel passenger cars there will be advances in their efficiency for those that want to purchase ones before production ends and the ability to have them registered for use on public roads.

 

EDIT.

If Governments are going to be delaying or postponing the date that ICE cars can be First Registered in their countries they need to get on and tell the manufacturers.

Credit to @e-Roottoot for predicting that this might be a very dodgy investment opportunity.

 

I've edited my initial post to include links to some heartily critical videos referencing the one I linked to. 

 

Alfadan have just started another crowdfunding round here, and currently the comments at the very bottom of the page include one from Joseph L. linking to the second of those, asking for response. Not sure how long that'll be there but it's stood for 8 hours so far. 

The Workshop fella has now put up a third video What a scam looks like - YouTube

 

Reminding me a bit of that electrolysis miracle thingummy 'ezero1'; except my instincts were sharper on that one. Might be that the intro stuff about secondary imbalance was a genuine learning experience  for me in this one, which put me in a receptive mood? Cunning.

Not sure how/whether this video fits into this, but plenty of comments querying the connection
