Engine Systems Flashcards
Horse Power
Total 400
Engine Type and Highest RPM
Lycoming and 2700
Location of the Cowl Flaps
Under Engine
How does the Fuel Injected system operated on Seneca?
Engine Air Consumption is measured, Air flow is used to control the fuel flow
Types of the Wing Flaps? How many Positions
Slotted wing flaps, which are mechanically operated by a four•position
How does the fuel tanks are connected?
Two interconnected fuel tanks fonn an integral part of each wing.
Talk about the elevator fhe plane
The stabilitor incorporates an anti-servo tab which improves longitudinal stability and provides longitudinal trim.
Location of the Oil Cooler
An oil cooler for each engine is mounted on the forward side of the firewall.
Air is picked up by air scoops on the side of the cowl, passed through the oil cooler and ducted overboard in thelower cowling.
Type of fuel System
fuel injection system
How does the fuel system operates?
principle of measuring engine air consumption and using the air flow to control fuel flow to the engine.
Explain the fuel injection system
Mounted on top of the engine
ported fuel flow divider with four nozzle lines routed to the cylinders.
Since fuel metering is provided by the servo regulator rather than the nozzles, more unifonn cylinder head temperatures
What kind of Propellers do we have?
Counter-rotation of the propellers Constant speed, Controllable pitch, Full feathering Hartzell propellers, Operated by oil and nitrogen pressure.
When can’t you feather the propeller?
Less than 800 RPM.
How does the Oil and Nitrogen operates for the propeller?
Oil pressure sends the propeller toward the high RPM or unfeather position, while nitrogen pressure sends the propeller toward the low RPM
OIL TEMPERATURE:
Green Arc: 75-245 deg. F
