What's your favourite engine?

Both Ford cross-flow and the Pinto engines were extremely reliable and so so easy to work on.
I converted the entire BMC petrol and diesel range of engines (Newage Marine) for marine use with cast iron sump’s and water intercoolers again so easy to work with.

4x Olympus engines, hard to beat in anyone's world

An engineer friend, fellow student at Reading, was doing research on the Humphrey pump. This has a liquid piston - the same water that it's pumping - with non-return valves either side at the base and conventional inlet and exhaust valves, and spark plug at the top of the cylinder.
He built a laboratory version with a glass cylinder, to demonstrate to his tutor and visiting professors. Partway through the visit it exploded, showering everyone with water and shards of glass. https://en.wikipedia.org/wiki/Humphrey_pump

That is a really clever idea. And once you've seen it is seemingly "obvious" yet I'd not have thought of it

Another vote for the Deltic engine

Another rather splendid Napier engine was the interwar W12 Lion. Originally an aero engine but found it's way into land speed record cars an fast naval boats

The engine on my old Honda Izy lawnmower. Never failed to start, went on and on without any maintenance apart from oil and was still perfectly alright when the rest of the mower finally fell apart after many years service.

Merlin?

I thought about the Merlin. It was definitely the most crucial British aircraft engine during WW2. It went through a great deal of development throughout the war. I have often which aircraft was most important to us in the war, Spitfire or Hurricane, but for engines it is easy. After the Merlin, I would count the various Bristol engines as the next most important, Mercury, Pegasus, Hercules. I would count the Napier Sabre as the third most important, British aircraft engine of WW2, and the Roll Royce Griffin as the fourth.

Merlin.
I was at Great Gransden in 2014 for the two Lancasters display. One Merlin sounds great, but eight was incredible.
RR Olympus.
Saw XH558 display at Shuttleworth a few times, including the last display flight.

I've been to East Kirby a couple of times, when they're running/taxying 'Just Jane', & you can get close, when they're firing up all 4 Merlins
The damn tailplane starts shimmying, with the slip-stream & vibration!!

If you want to pay, you can have a taxi-ride; https://www.lincsaviation.co.uk/

Seen XH558 take off/land a few times
Sadly only once similar to this, almost a Cold War Scramble

As I'm currently on the train returning home from a day out on the Bluebell Railway in Sussex it would be rude of me not to choose the locomotive that just propelled me from Sheffield Park to East Grinstead

CBX1000

 

[FishFright]

Small Block Chevy , it can do most things it's ask to do very well and did it for decades.

A V twin Guzzi has the sort of deep rumble that wiuld make you want to never switch it off.

Everything should sound like that, even your watch.

 

[raleighnut]

Too many to list all of them but the Deltic, the Lotus-Ford 'Twincam', the TZ Yamaha, and the T50 are close to the top

 

[Oldhippy]

Personally, my heart.

This is the correct answer.

Nah, give a Western any day! 🤣
