Summary: | The invention discloses a mechanical and electronic control dual-redundancy fuel oil supply system suitable for a multi-fuel two-stroke aviation piston engine, which comprises a main fuel oil injection system and a backup fuel oil injection system, and the main fuel oil supply system and the backup fuel oil supply system adopt two sets of independent rotating speed sensors. The main fuel oil supply system and the backup fuel oil supply system are used for generating input signals to be provided for the main engine control system and the backup engine control system respectively, and sensor signals received by the main fuel oil control system and the backup fuel oil supply system are mutually communicated; the main fuel injection system and the backup fuel injection system adopt a common high-pressure fuel pipe and a common fuel injector, and both the main fuel injection system and the backup fuel injection system can independently control fuel injection of the diesel engine; when negative carbon fuel or a mix |
