Hi All,
I have a hydrostatic loader with a Kubota D1105-E4B engine. In Australia, we do not yet have to comply with Euro V or EPA Tier 4 emissions standards, so I would like to bring it back to its former E3B 3600rpm glory, or perhaps even a little more if it is safe to do so.
As far as I can tell from the specs, the only differences are:
D1105-E4B:
18.5kw/24.8hp @ 3000rpm
Max 3200rpm
Injection Timing 18° BTDC
Compression Ratio 24:1
D1105-E3B 3600rpm:
21.7kw/29.1hp @ 3600rpm
Max 3800rpm
Injection Timing 20° BTDC
Compression Ratio 23:1
Can anyone offer any advice on how to go about things?
I saw an old post where SkyPup was talking about changing injector nozzle size a few microns to increase power (Post Here), but I can't find any information on Denso DN0PD injector nozzle hole sizes. As far as I can tell, the original part number for the standard nozzle is 16261-5361-0.
