Got the solenoid working
[ame]https://www.youtube.com/watch?v=Un0HZwI8pwg&list=UUL8gj_06zIsMRLY-U6zQItA[/ame]
This engine is called EGG Engine, which stands for Electronic Guided Governor which is a 4 cycle hit and miss, water cooled engine and is based on my own design. The bore and stroke for this engine is 0.75” x 0.75”
As you can from the pictures, the governor is a small solenoid which gets activated based on PRM. The micro controller measures the PRM and activate the solenoid when PRM reaches certain level and deactivate the solenoid once drop to certain level.
Currently on the test bench the solenoid work but as you can see in the video, the solenoid doesn't get activated.
2 things could be the cause
1. Bug in the micro-controller code which I need to review again
2. It could be the back and fort of the push road is so fast that doesn't
give the solenoid enough time to fully opened?
Also carburetor needs improvement. Maybe I switch to RC carburetor
Any help and idea would be appreciated.
Here is the first run video
