Spirit V2 Aircraft Engine
Spirit Engineering designed and manufactured the Spirit V2 aircraft engine with a focus on reliability, simplicity, power output, maintainability, and weight.
The Spirit V2 is a normally-aspirated, two-cylinder, four-stroke, inverted “V”, air-cooled, direct-drive aircraft engine featuring a dry sump lubrication system, and a magnetic discharge ignition. This engine is perfectly matched to the SE-1 aircraft.
