Engine, an Aircraft, and a Throttle Thereof
An aircraft having an engine and a throttle thereof. The throttle has a throttle body ( 1 ), the throttle body ( 1 ) is provided with a cavity ( 10 ) and comprises an inlet port ( 11 ) and an outlet port ( 12 ) both of which are connected to the cavity ( 10 ); a plurality of fuel injectors ( 2 ), each of the fuel injectors ( 2 ) is arranged on the throttle body ( 1 ) and can spray fuel into the cavity ( 10 ) of the throttle body ( 1 ); and an air filter ( 3 ). The air filter ( 3 ) is arranged on the throttle body ( 1 ) and connected to the inlet port ( 11 ). There is an air door ( 4 ) that can rotate in the cavity ( 10 ) to connect or block the inlet port ( 11 ) and the outlet port ( 12 ). Additionally, there is an air door driving part connected to the air door ( 4 ) and controls the rotation of the air door ( 4 ).
