Lycoming IO-233
The Lycoming IO-233 is a non-certified four cylinder, air-cooled, horizontally-opposed piston aircraft engine that produces between Template:Convert and Template:Convert.[1]
The IO-233 is a development of the Lycoming O-235, which is itself a derivative of the older Lycoming O-233 engine.[2]
Development
The IO-233 was announced by the company at AirVenture on 28 July 2008 as a new engine for light sport aircraft. The engine was conceived as a lightened version of the Lycoming O-235 by company engineers who were building their own kit LSAs and found that there was no powerplant that met their requirements for power output and weight, with the ability to burn either 100LL avgas or unleaded autofuel.[1]
The resulting engine offers weight savings over the O-235 and incorporates a throttle body injector system with a tuned intake manifold and dual electronic ignition. The engine has a 2400 hour time between overhauls. Additional features include a lightweight 14 volt alternator, an optimized oil sump, a streamlined accessory housing, a lightweight starter and roller tappets.[1][3]
When announced in July 2008 Lycoming expected the engine to be available later that year, once ASTM testing for LSA use was completed. The company also contemplated certifying the engine in 2009, although there is no indication that either the ASTM testing or certification has been completed.[1]
