100 - 300hp piston engine UL520T

100 - 300kgfor light aircraftfor ULM

The UL520T is based on the well proven UL520 but now with a turbo charger / normalizer The main goal of this turbo is not to create a big boost in HP but rather to compensate for the loss of atmospheric density during all phases of flight, and thus eliminating the loss of power seen with elevated altitudes. The UL520T maintains its 220HP from sea level up to 15000 ft. An ASTM compliant version (with dual ECU) is available as well. Dual (redundant) electronic spark ignition (variable timing) Electronic multipoint fuel injection (pressure and temperature compensated) Electronic RPM limiter Electronic overboost limiter Direct propeller drive 7 bearing crankshaft with surface hardening treatment and additional large thrust bearing (ball bearing type) Single central camshaft Push rods, tappets and OHV (hydraulic compensators have not been used) Wet sump forced lubrication with integrated pressure regulator Ram air cooled cylinders and cylinder heads Integrated permanent magnet AC generator, external rectifier-regulator Factory installed exhaust system with integrated turbo charger and waste gate.
