ð· upright 90 degree V-4, turbocharged, direct drive, two-stroke diesel with oil pump and external air-oil separator/sump

ð· top profile is 3.5 inches higher at the cylinder tops than an IO-360 Lycoming, referenced from the crankshaft

ð· 150 and 200 hp models, at 2,700 rpm

ð· BSFC = .38 lb/hp/hr

ð· for a 1,000 nm trip in a Velocity at 65% power, this translates to:

ð· currently about 270 lbs including starter, oil pump, fuel pump, water pump, alternator, turbocharger, all internal lines and internal exhaust system

ð· lower part count and fewer potential leakage points than the current 4-cylinder gasoline-powered aircraft engines:

ð· fully doweled, four bolt main construction (12 studs)

ð· inherently stout block and compact V-4 design

ð· single-lever power control

ð· configured for fixed or variable pitch propellers (propeller governor pad provided)

ð· vacuum pump pad provided

ð· limited operation at reduced power without coolant

ð· limp-home capability without turbocharger, supplying approximately 100 hp with backup air

ð· no electromagnetic interference at normal operating altitudes

ð· provisions for cold weather starting

ð· TBO of 2,000 hours (estimated)
