Hydraulic oil mixed with automotive oils

(1/2) > >>

rdbates1:
I'm having a very hard time finding WMO.  Would a Changfa burn a mix with a large percentage of hydraulic oil mixed with various automotive oils?  Another option might be a hot bulb engine but would it react to the fuel about the same as a regular diesel?

A diesel engine can be made to run on almost any oil. You may have to mix it with kero or regular diesel to get the viscosity you require, especially if you live in a very cold climate, some people use regular gasoline as thinner. Many people use different blends for summer and winter. It is vital that your blended fuel is filtered down to at least 5 microns to ensure no metal particles get into the fuel system.
You might find it advisable to use a two tank set up where you start on regular diesel before switching to your blended fuel. It is also common to switch back to regular diesel before stopping the engine, this ensures an easy start the next time.
A further problem with hydraulic oils is that some are hydroscopic and will absorb water out of the atmosphere over time.
This could cause corrosion issues to fuel tanks, pumps, injectors and etc.
Most people running WMO find that they get carbon deposits inside the engine which can lead to premature engine failure, this is readily treated by water injection which cleanses the cylinders of these ash deposits.
good luck,

For water injection, I've thought of using a garden personal cooling mister since it's low volume and creates a fine mist.  The engine will run 24/7 driving a 5k generator feeding a grid tie inverter so the load should be constant and also near the capacity of the engine.  I'd like to be able to run veggie oil but there is a large bio-diesel refinery in town and the grab every drop of oil in the area.

Hi rdbates1, I don`t quite understand the set up you are proposing. A grid tie invertor is usually connected to the mains supply and converts dc power to ac power to match the voltage and frequency of that mains supply. This allows home generated power to be safely used on site or exported to the grid. Does your Changfa produce dc power or are you planning to rectify it before sending it to the invertor? Perhaps you are talking about a system with a cross over switch so you can run everything off the generator but switch back to mains power in an emergency.

Perhaps I have misunderstood completely and you are planning to use the generator to provide the voltage and frequency side of the inverter which would allow for solar panels and or battery backup to supplement the generator. I`m not sure how well that would work as the frequency and voltage would only be as stable as the governor/AVR on the generator.
 
A lot of people just squirt water into the air inlet, the engine will start to bog down if you give it too much. You don`t have to run water into it all the time, just a regular flush should do it. There are people on the forum who have set up automatic water injection systems but I don`t know how successful or otherwise these are.

Very sorry to hear that some greedy sod has taken all the WVO for biodiesel. Straight WVO dried and filtered would have been a good fuel for your setup. Perhaps you should open a fast food joint and recycle your own waste oil.

I'm planning to run a 240v generator head and boost/retify the output to around 315v DC which is the optimal input for the inverter I found.
I'll also be running a waste oil fired boiler.  The reason for the project is I bought a house in western Oregon with a pool.  In the summer with the A/C and pool pump running power runs upwards of $250 a month with gas at around  $80 for hot water.  In the winter gas and power prices flip. With both running I should be able to reduce my energy costs to very little and heat the pool which is pretty chilly even in August around here.
