Small Diesel Engines
For no good reason, I am looking at used diesel engines.
The prices for VW diesel engines is insanely cheap. Go to Ebay and type in "4 cylinder diesel engine" and most of the items are over $2500
Simple kits for VW diesels can be had for $500. Other kits include pistons that are 0.020" oversize so the worn cylinders can be honed out and re-trued. Those kits cost $750.
VW diesels have a timing belt that is good for about 150,000 miles or maybe 3000 hours. That is duty related. Running an air compressor will cause more torque pulsing and will be harder on a belt than running a steady 2000 RPM on a generator.
The older diesels have mechanical injector pumps and probably don't care about the application provided you can cool them and feed them good fuel.
The newer diesels have common rail and electronic injectors. That means the Powertrain Control Module runs the show and will get its panties in a bunch if it does not see all the sensors-reading-in-the-green.
Just out of curiosity, I wonder if there are PCMs or chip--sets that can be used to repurpose a VW, common-rail diesel to agricultural power or stationary installations like generators?
I know the boys running Duramax, Cummins and Powerstrokes around here can get "chips" to roll-coal.
