I have a marine diesel engine, and I'd like to calculate the approximate fuel consumption based on the size of the engine, at a given number of RPM - specifically for the cruising recommended cruising RPM of 2880 - 3240.
Guidance online varies from the super generic and unclear to PhD abstracts that are way over my head. I'm not sure exactly what details are needed but wouldn't it be the size of the cylinder (bore and stroke) x cylinder size x RPM?
My engine is a 3 cylinder Nanni:
- Max Power: 21.3 kW / 29HP
- Compression rate 22:01
- Bore & Stroke (mm): 78 x 78.4
- Recommended cruising (RPM): 2880 - 3240
P.S. happy to take advice using non-metric, but if so please just be precise in terms of what you're using (e.g. people talk online about "gallons" but not whether it's "US Liquid Gallon" or "Imperial").
