and this is a cut and paste off your detailed 'engineering' pls dont laught to much when reading
Oldblue: It was me that pointed out that a new interface to the Stirling would be required and would need designing from scratch and would not be easy. As usual you are answer things that don't need answering
As for adding random numbers, what on earth are you talking about. The problem is very simple and there is no odd maths involved. The Stirling produced 10.3 HP. That is 6.4 kW increased by 20%, GCSE MATHS. A D13, the lowest output being 375 HP. If I increase the D13 output using all 10.3 HP of the Stirling I get an improvement in efficiency of 2.7 %. It could not be any simpler. If I were to add the Stirling to the 1000 HP version, what improvement would I get ?. This is kids stuff.
For the size and weight and presumably the cost, the benefits to Volvo are very very small. Presumably that's why they haven't even committed to an actual test on a real D13 because they know it's waste of time. The development will be strung out as was the Charger, enticing RNSs will written but it be another waste of time and money for investors.
Oldblue: you seem determined to ignore what I write and simply make up your own story! I think I've made it clear. After demonstrating a model and running a theoretical analysis In-spirit claimed in RNS 3 Nov 2020. " , the novel three stage heat recycling process increased engine efficiency by approximately 20%, driven by waste heat from e.g. a Volvo Penta D13 series engine... "
So 20% more power from the Stirling engine when pumped full of heat from say a D13. I do not mention Chargers, I talk about Stirling engines! YOU talk about Chargers and 20% more power equals a Stirling producing 10.3 HP. To be crystal clear, In-spirit only have 1 Stirling engine design and it supposedly produces 6.4 kW, convert to HP and multiply by 20% and you arrive at 10.3 HP. That is what In-spirit states the Stirling will produce when blasted by the huge amount of waste heat from a D13, you don't have to calculate, they tell you the answer - 10.3 HP.
The Volvo WHR system is a heat collecting system that comprises, the recently coined IHA and that heats the second component, the Stirling engine.
The Charger and the Volvo WHR system ARE connected, by the common factor i.e. the Stirling engine ... Wrong again Oldblue.
