I have learned the hard way to always back up your important files. A few months ago I accidentally spilled water on my laptop and destroyed it. I lost everything that I was working on and, out of frustration, decided to put this entire project on hold. That was then but now I have a new laptop and it was only a matter of time before I began tinkering with designs again.
I was reading through this blog before posting this and realized that a fresh start may not be such a bad idea. Instead of trying to design any major components, I will solve the problem of valve actuators and position sensors first. Once I have a viable solution, then my focus will shift to intake/exhaust ports, combustion chambers, and piston design. I will worry about what comes after that once the time arrives.
I have been doing some research and found a GM patent that I thought was very interesting. Click here to check it out.
