MOONEY M20R - OVATION 2 GX SECTION VII AIRPLANE AND SYSTEM DESCRIPTION IGNITION SYSTEM Power from the engine crankshaft is transmitted through camshaft gear to the magneto drive gears, which in turn drives the magneto drive couplings. The left magneto incorporates an impulse coupling. As the rubber bushings in the drive gear turns the coupling drive lugs, counterweighted latch pawls inside the coupling cover, engage pins on the magneto case and hold back the latch plate until forced inward by the coupling cover. When the latch plate is released, the coupling spring spins the magneto shaft through its neutral position and the breaker opens to produce a high voltage surge in the secondary coil. The spring action permits the latch plate, magnet and breaker to be delayed through a lag angle of 30 degrees of drive gear rotation during the engine cranking period. Two lobes on the breaker cam produce two sparks per revolution of the drive shaft. After engine is running, counter--weights hold the latch pawls away from the stop pins and the magneto shaft is driven at full advance. The engine firing order is 1--6--3--2--5--4. Ignition harnesses are connected to the magnetos so right magneto fires the upper plugs on the right side and lower plugs on the left. The left magneto fires the upper plugs on the left and lower plugs on the right. The magneto cases, spark plugs, harnesses and connections are shielded to prevent radio interference. FILTER NACA AIR INLET FILTER CAN FUEL CONTROL UNIT ALT. AIR BOX ENGINE INDUCTION AIR SYSTEM FIGURE 7 -6 AIR INDUCTION SYSTEM SCHEMATIC AIR INDUCTION SYSTEM The engine air induction system consists of a NACA, flush--type air inlet duct located on front of lower cowling. The air inlet duct incorporates the air filter housing. This housing contains a throw--away, paper canister type air filter element. The optional air filter is cleanable and must be serviced at 100 hour intervals. Refer the maintenance manual for instructions. A secondary or alternate air source for combustion air is provided. This air inlet has a spring loaded door which normally remains closed. If the air filter or induction air inlet should become ORIGINAL ISSUE - 12-11-07 Revision A -- 08-03-2010 AIRPLANE FLIGHT MANUAL 7--21
