I've started this endeavor by purchasing a BLDC motor-driven positive displacement gear pump that claims to deliver at least 50 bar at 900cc per minute, we'll all get to see how far that gets me. I already have several vESC-compatible motor controllers that will accept several different types of control input such as CAN bus, TTL serial, and hobby R/C PWM signals, many if not all methods will be tested to see what is best. While doing so I will continue searching for suitable small engine throttle bodies as anything smaller than about 800cc is seemingly currently unobtanium.
To be clear my project is to investigate the viability of pairing a Speeduino management system with the vESC BLDC motor controller project to create a controllable constant flow fuel injection system that is mechanically simplified at the expense of adding electronics compared to a classic drag or circle track Hilborn constant flow mechanical fuel injection system with its cam or belt driven fuel pump, main-jet (bypass flow pill) and barrel valve connected to a throttle body to both tune and control the flow of fuel into an engine.
The goals of my project are as follows,
1. reduce the cost and overall plumbing complexity vs classic mechanical CF injection. (from now on simply MCFI)
2. overcoming a number of the technical pitfalls of MCFI, such as trimming air/fuel ratios on the fly
3. overcoming the sensitivity some small high-speed engines experience with mixture instability induced by EFI pulsation.
4. multi-fuel staging IE GAS to Alcohol or GAS to Nitro!
