Ecotrons, trading as EcoEFI, is a company in Encino, California, that sells electronic fuel injection and engine-management products for small engines, including those used in UAVs.
The catalogue includes EFI kits for engines from 35 cc to 300 cc and from 400 cc to 800 cc, kits for the Briggs & Stratton Junior 206 and the Honda GX35, and a small-engine management system. A UAV engine EFI package includes automatic altitude compensation, which keeps the fuel mixture matched as the aircraft climbs.
Its engine control units are offered as vehicle, small-engine and throttle control units, with a break-out box for bench work. Components include throttle body assemblies, fuel injectors, throttle position, manifold pressure and intake or coolant temperature sensors, and small-engine fuel pumps. The ALM series of wideband lambda and air-fuel-ratio controllers comes as inline, board, CAN, RS485, LED and dual-channel variants, with Bosch LSU 4.9 and LSU ADV sensors. Calibration tools named EcoCAL and EcoCoder support engine tuning.
This range suits builders of piston-powered UAVs who want to replace a carburettor with closed-loop injection; compatibility with a given engine should be confirmed with the supplier.
