Engine Fuel Injection
The Engine Management is designed to manage and control petrol engines from one central Injector to four sequential Injectors.
The Engine Management does not need to be connected to a PC, which is often difficult when running petrol engines in the given environment.
Engine Management - Main Unit
-
sequence control of 1 to 4 Injectors
- one Injector – one, two, four-cylinder engine
- two Injectors – two-cylinder engine with sequential control, or
-
four-cylinder engine – one pair = one Injector
- four Injectors – four-cylinder engine with sequential control
-
6x temperature input
- CHT, EGT, water, oil sensors
- fuel level sensor – capacitance fuel sensor
- fuel consumption measurement
-
2x voltage measurement
- Main power supply
- Servomotor power supply
-
fuel pressure measurement with possibility Fuel Pump regulation
- constant (adjustable) power Fuel Pump – mechanical press. regulator
- automatic Fuel Pump – adjustable fuel pressure
- wideband oxygen sensor
- ECO and MAX Power mode
- timers
- choice litter or gallon
- choice °C or °F
- Export data to flight computer
