Its been some time since my last update,
Where am I at now, Engine is in it's "soundproof" box I had to overhaul it completely. Started with a piston and liner, there was play on a shaft key so fuel injection was late giving tons of smoke. Neighbour complaining. pffff. Put a new shaft key and replaced all roller bearings.
There's 2 shims under the fuelpump so you can move the injection time ahead a bit, removed one might take out the other one. Think wear on the gears moved injection time late as well.
Just had it running for two hours 3000 watts, running smooth satisfying.
Exhaust goes threw a pool heater dropping temperature to 80 dergr celsius with a flex tube to an old square water tank of a boat approx 250 ltrs, inside rockwool and 2 chambers to kill the exhaust noise. Lister I had 4 chambers and it was completely dead, now you can hear the exhaust but extremely soft.
Big point of attention the exhaust from the pool heater which is mounted to the engine and moving to the tank which is rigged I have a flex stainless hose of diam 80mm but its moving like crazy.
That will not last 100 hours before something breaks and starts leaking.
Need to figure out something sexy.
Automation, I mounted my servo motor on the fuel rack/governor with mqtt messages. So via wifi connection I could alter the load of the engine. It works but needs some tidying up.
I was using a type of esp8266 board with external wifi antenna very good but fragile, in other words I burned a few. Think I will use a plastic box so I can use a normal board.
I have my electricity meter sending messages every 10 seconds so I can adjust the load of the engine to match the demand.
rest of the stuff, cooling water flow, temperatures and start stop was already working on the lister so only have to drop it on.
