AI Technical Summary
Traditional glow plug preheating methods consume a large amount of battery power in aero engines, which is not suitable for overall weight reduction and energy saving, and the excessive cooling of engine intake air affects combustion efficiency.
The electronic fuel injection throttle body, which uses exhaust gas preheating, heats the air intake by heating the exhaust gas and the inner wall of the valve body through an annular channel, thus indirectly preheating the intake air temperature. Precise control is achieved by controlling the valve plate opening through a swing arm.
It reduces heating power consumption, improves combustion efficiency, reduces fuel consumption, and has a compact structure and is easy to process.
