Stork Ricardo AR214 starting and running

This video shows the start up and running of a Stork Ricardo AR214 diesel engine build in 1956. It's a four cilinder four stroke engine with 2 valves per cilinder. Special about this engine is the so called "Ricardo" pre-combustion chamber. The fuel is injected in this specially shaped chamber where the initial combustion takes place before the hot gasses move on to the top of the cilinder. This design made the egine more efficient and more powerful. Nowadays better fuel pomps and electronics makes a pre-combustion chamber useless, but in the 1950's it was quite revolutionary.

Re to AltRage: On top of the engine, I need to open the decompression valves, which allow the compressed air in the cilinder to escape, else it would not be possible to rotate the flywheel by hand.

loopt ie maar op 3 pitten?

Geloof me, het zijn er echt 4! Bij 170 toeren loopt de motor een beetje bokkerig. Zal binnenkort nog een filmpje plaatsen met 300 toeren per minuut.

Lovely music! What was their main application? Rail? Marine? Power generation? The Doxford type engines with opposing pistons in each cylinder were powerful, efficient but complex, with difficulties in maintenance. They passed into obscurity without too much regret from marine engineers once turbocharging became reliable on conventional engines. I wonder if that was part of the reason for Stork Ricardo fading away?

sounds like really low RPMs

If only I could squeeze this magnificent motor under the bonnet of my car!

Great sound.

hand oiling all 3 hours running haha

It surprises me that the opperator did not prime the lubrication before starting the engine. Usualy, when starting this kind of engine prior to start, oil pressure is build up using a hand pump, so that when air starting is aplied, there is already oil pressure.

You do something on the top of the engine, rotate the flywheel to an exact position, and then undo that same something on the top of the engine. I am very curious what you are doing there. I have a basic understanding of engines, so you don't have to explain what valves are, or how fuel injection works. Thanks very much in advance, and thanks for a great video. I really enjoyed it.

what is this diesle engine looks very old thre should have been a nateratio the fact it dies not have a valve cover what is it i uwed for?O never seen apicture o of any thing like itI wonder were you getparts for is

[ledanielzeppelin]

what is it horsepower?
