NOTE 4. The Turbocharger meets the containment requirements of CAR 13.116 and does not require external
protection.
Measure exhaust gas temperature at inlet lo cation shown on Lycoming Drawing No. 63232(-A1A, -A2A,

cooling oil jets.
NOTE 6. Spark plugs approved for use on these engines ar e listed in the latest revision of Lycoming Service
Instruction No. 1042.
NOTE 7. These engines incorporate the following similarities or differences:
TIO-540-A1A Basic model. Six cylinder, air-cooled , horizontally-opposed, direct drive, fuel injected,
top exhaust, turbocharged engine incorpor ating internal piston cooling oil jets. Uses
two-blade propeller.
TIO-540-A1B Similar to -A1A but has density controller with faster temperature response.
TIO-540-A2A Similar to -A1A except has prope ller flange bushings which accommodate either a
two-blade or three-blade propeller.
TIO-540-A2B Similar to -A1B except has prope ller flange bushings which accommodate either a
two-blade or three-blade propeller.
TIO-540-A1C Similar to -A1B except BSFC is in creased to .67/bhp-hr and the manifold pressure
increased to 40.0 inches Hg.
TIO-540-A2C Similar to -A2B except BSFC is in creased to .67/bhp-hr and the manifold pressure
increased to 40.0 inches Hg.
TIO-540-C1A Differs from -A1A with lower compre ssion ratio, different counterweights, and parallel
valve cylinders.
TIO-540-E1A Similar to -C1A except rating is incr eased, different turbocharger control setting and
uses Bendix S6LN-1227 magneto instead of S6LN-1208 magneto.
TIO-540-G1A Similar to -C1A except for higher compression ratio.
TIO-540-H1A Similar to -E1A except rating is increased.
TIO-540-F2BD Similar to -A2B except rated power is increased and incorporates the Bendix Dual
Magneto.
LTIO-540-F2BD Similar to -F2DB except that it has counter-clockwise (reversed) rotation.
TIO-540-J2BD Similar to TIO-540-F2BD except rated power is increased and is equipped with an Air
Research Model THO8460 turbocharger.
