Diesel engine efficiency can easily exceed 40-50% using currently existing technology and it'll run over a wider range of RPM than this thing.
This sounds like something that'll be great 'so long as you give us the funding'. And it's big advantage of mechanical simplicity will most likely be nullified in the real world with the addition of the usual automotive ancillaries. Given how reliant this design is on pressure pulses to time it's ignition... it's going to be great fun getting one of these to run well with all the plumbing necessary to drop exhaust noise down to something acceptable. One thing about engines which use detonation to ignite their fuel.... it's a very loud process.
That, and I suspect it'll only run really well over a very narrow powerband, similar to an old two-stroke which is less of a problem when hooked to a generator mind.... but if you want any amount of power out of it, it's either going to be very big, or very fast running leading to either a reduction in efficiency, or a massive increase in noise.
