Tham khảo sách 'the engine is the beating heart of the airplane 88', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | SAFETY ADVISOR Technology No. 4 Operations Do you know what to do if the engine burps and coughs during the runup or runs rough during cruise In-depth systems knowledge can give you the tools needed to assess the engine s actual condition. Aircraft engines are extremely reliable when properly cared for and can deliver years of safe flight. That being said not all pilots know as much as they should about The engine is the beating heart of the airplane. the proper care and maintenance of engines or that mechanical failure accounts for 15 to 20 percent of all accidents. Knowing how to manage a powerplant helps you fly more safely and can minimize the cost of flying . Whether the aircraft you fly is equipped with a sophisticated engine monitoring system or not a basic understanding of how engines work is required to correctly diagnose potential engine problems. For all engines air is drawn into the engine mixes with fuel burns at a controlled rate and expands pushing on a piston that turns the crankshaft and propeller. Most piston aircraft engines develop power with four cycles or strokes of each piston inside a cylinder. The four cycles are intake compression power and exhaust. Cockpit engine controls usually the throttle prop control and mixture allow a pilot to extract the most efficient performance from the engine and ensure safe and reliable operation. FADEC Full authority digital engine control FADEC incorporates the throttle mixture and prop control into one pilot controlled lever. The FADEC system provides many benefits including increased efficiency lower fuel burn and troubleshooting tools for diagnosing engine problems. Engine Operations Pg. 1 The Basics Intake Valve Opens to allow the fuel-air mixture into the cylinder. Pistons The controlled burn forces the piston to move within the cylinder. Spark plugs Provide the electric spark that ignites the fuel-air mixture. Crankshaft Attaches to the connecting rods and the propeller. The motion of the pistons .
