reb Posted August 10, 2022 Share Posted August 10, 2022 What's an engine configuration you wish existed? We've had a few good ones over the years that didn't stand the test of time, my favourite being the I5. What about the ones that have never existed? Which would have the most distinctive sound do you think? Which might have been a winner if only someone had tried it? Link to comment Share on other sites More sharing options...
PrinceRupert Posted August 10, 2022 Share Posted August 10, 2022 What about an X configuration. According to Wiki, Honda once experimented with an X-32 for their Formula One cars ... https://en.wikipedia.org/wiki/X_engine Link to comment Share on other sites More sharing options...

Conan Posted August 10, 2022 Share Posted August 10, 2022 For anyone interested in this topic I'd suggest giving a YT channel called William Moser a watch. This guy simulate combustion firing noise along with visualisation in form of light bulb and the result actually sounds a lot like real engine would. There's A LOT of theoretical firing order shown and also a lot that does exist but not in high rev application like in typical passenger cars. I'll provide an example starting with 1.

JimH Posted August 10, 2022 Share Posted August 10, 2022 I like the idea of double acting IC engines. Aside from that it would be nice if someone built a dinky Delta engine. That would sound nice. CreepingJesus 1 Link to comment Share on other sites More sharing options...

I was leading up to this: https://youtu.be/RKT-sKtR970 It's an insane level of detail just to simulate the noise of an arbitrary combustion engine.

big_al_granvia Posted August 10, 2022 Share Posted August 10, 2022 the flat 4 as per vw and subaru is great in theory but all the valve gear makes it, well wide... what about a flat 8 with 2 crankshafts geared together but 2 stroke..... or a smoller version of the napier deltic for automotive AnnoyingPentium 1 Link to comment Share on other sites More sharing options...
Honey Badger Posted August 10, 2022 Share Posted August 10, 2022 I'd like a miniature Napier Sabre H 24, about 5 litres fitted into a 90s Lexus SC body. I'd also like a discount card for spark plugs. catsinthewelder, AnnoyingPentium, Asimo and 1 other 2 2 Link to comment Share on other sites More sharing options...
Asimo Posted August 10, 2022 Share Posted August 10, 2022 I'd like a 120° V6. Short and stiff 3 throw crankshaft and even firing intervals. Relatively low centre of mass and although balance is not perfect like an inline 6, much easier to package than a flat 6, not to mention cheaper to make. Porsche: 120° V6 is what your base 718 needs, not that dreary "Impreza" engine. Air-cooled of course! A few racing engines have used this configuration but as far as I know the most numerous is the Diesel engine used in many Soviet-era military applications, thousands of which have been destroyed since February 24th.

Fitting a smaller Deltic engine into smaller automotive applications might be tricky for packaging reasons but it’d make an epic engine for a Heavy Haul tractor unit. warch, twosmoke300, big_al_granvia and 1 other 4 Link to comment Share on other sites More sharing options...

Richard_FM Posted August 10, 2022 Share Posted August 10, 2022 I remember years ago wondering if a W-9 has ever been made, with 3 banks of 3. It would need a fair bit of balancing. BRM considered a W-12 for the 3 litre rules, but went with an H-16 which ended up being too complex. Link to comment Share on other sites More sharing options...

Datsuncog Posted August 11, 2022 Share Posted August 11, 2022 Stranger than fiction... The DAWB 6 - featuring an air-cooled inline transverse 6 cylinder engine with a dry sump, displacing 1.4 litres and with three twin-choke Weber carbs fitted. The entire car was built from scratch from the mid 1950s to the early 1960s, with an engine configuration that I've never heard of - but then quietly pushed into the corner of its birthplace in a Belfast machine works once complete and almost never driven by its creator, Davy Woods.

vulgalour Posted August 11, 2022 Share Posted August 11, 2022 Vertically opposed (like a Junker) sixteen cylinder but the pistons are in pairs connected to the crankshafts (like a Trojan, but there's two crankshafts instead of one) and it's rear mounted and air cooled (like a Tatra) and there's a supercharger somehow (like a Bentley) and it has mechanical fuel injection (like a Mercedes Benz). I literally cannot imagine what that would sound like. Lacquer Peel 1 Link to comment Share on other sites More sharing options...
