Austro Engine and Diamond Aircraft Industries have received EASA Type Certification for the Austro E4 turbo-diesel general aviation engine (the AE 300). The AE 300 is an inline four cylinder, 2.0-liter piston engine which uses Jet A1 or diesel fuel to produce 170 hp (127 kW).

The AE 300 is a liquid-cooled, with a double overhead camshaft (DOHC). Every cylinder has four valves which are actuated by the cam follower. All engine components are controlled by an EEC system.
The engine is equipped with an electrical starter, an alternator, a water pump, an oil pump, a coolant system, an intercooler and an oil cooler. The propeller is driven by a directly integrated gearbox with an integral torsional vibration damper.
The certification process took 42 months at a cost of about €48 million (US$62 million).
The complete program developed into one that was significantly more complex than originally anticipated. Only the full dedication of all participants, specifically the Austrian and European Airworthiness Authorities, MB Tech, Bosch General Aviation Technologies and our employees, enabled the successful conclusion of the certification process.—Christian Dries, Diamond CEO
There are already 27 Diamond DA42 airplanes with AE 300 engines on the production line, the company said, and type certification for those aircraft is also expected. AE 300 powered versions of the DA40 and the DA50 will follow. Diamond will offer a retrofit solution for the existing diesel-engine-powered Diamond fleet.
