  • Thank you. You are on your way already - just study many of the models posted here, and you will get ideas on how they work.  Some are easy to figure out. Then try building some simple models and you will grow to success. I will try to help you.

  • wauw, nicely made!!!

    how can I make a hobby of this?

  • At max RPM it could be geared down to produce enough torque, but it is very heavy with battery pack and all the hardware. Stationary function is best.

  • does it produce sufficient amounts of torque? possibly enough to put into an RC car?

  • Thank you. I am retired now with time to exercise a life's passion. This was one of last winter's projects. Please view my other videos.

  • man, that is so elegant, do you work for the NASA? thumbs up if agree

  • Lovely work, beautiful engine. Got to go look at your other videos!

  • I should add that the aparatus on top of each cylinder designed to resemble intake and exhaust ports actually serve as heatsinks and help disipate heat.

  • Thanks for viewing. Like all engines, it works best when all moving parts are lubricated (lightly). Since it is a 4 stroke, it does 'nt seem to get too hot. Apparently the non firing stroke (the exhaust stroke) provides a cooling effect. I'v not run it long enough for it to heat up much. Thanks for your interest.

  • do the solenoids dry up or do you have to keep them greased or oiled? do they get really hot?

  • Each cylinder is wired and switched seperately. After the MAIN switch the first of the four switches "fired up" cylinder #1; the second switch "fired up" cylinder #2, etc. Each time an additional cylinder came into play the additional force of another cylinder fireing increased the torque and RPMs till all 4 cylinders were powered for maximun speed and torque. Then the rheostat, which is in the main line, can also regulate the current delivered to any of the activated cylinders.

  • Thank you. To regulate speed I used a simple rheostat but would like to learn how to build an electronic design. Can you advise me?

  • Thanks for your response to my video. Your machine is really an awesome design! Lot of work to do this! What kind of speed regulator do you use?
