The TDA CR 1.9 8V EASA was certified on 11 June 2010: a 1.9 L liquid cooled, 4 cylinder, 4 stroke, 8 valves engine, with a turbocharger and Common Rail injection, a 1:0.644 reduction gearbox and dual FADEC, it produces 118kW (160hp) at take-off and 107kW (146hp) continuously at 2450 propeller RPM for 205kg (452lb).[2]
It made its maiden flight on 17 January 2005 with an IAI Heron UAV.[1]
It powered the Alenia Aermacchi Sky-Y UAV demonstrator on its 20 June 2007 first flight[3]
Its 82mm bore and 90.4mm stroke lead to a 1910 cm3 displacement, it have a 16.0 compression ratio and a 1600 bar common rail and the manufacturer announces 190kg (420lb), 121kW / 165hp maximum and 110kW continuously till an 8000ft critical altitude and a 225g/kWh (0.370lb/(hp⋅h))fuel consumption.[4]
It is based on the 1.9 JTD engine.[3]
DieselJet TDA CR 2.0 16V engine
The TDA CR 2.0 16V, certified 8 March 2016, is a 2.0 L 16 valves engine with a 1:0.607 reduction ratio and a similar configuration, producing 142kW (193hp) continuous and 160kW (217.5hp) at take-off at 2306 propeller RPM for 219kg (483lb).[2]
It powered the IAI Super Heron first flight in 2012 and aims for a 1,500 hours MTBF, a 1,000 hours Time between overhaul initially then 2,000 in service for a €25,000 Cost and a 2,000 hours initial service life then 4,000.[1]
The 1955 cm3 engine has cylinders bores of 83mm and 90.4mm strokes, a 16.0:1 compression ratio for a 210g/kWh (0.35lb/(hp⋅h)) min. brake specific fuel consumption, its manufacturer claims 205kg (452lb), a 8,700ft critical altitude and operability till 35,000ft.[5]
A light-sport aircraft gasoline engine GA 1.4 8V was in development in 2014-2016.[1]
Based on the Fiat FIRE engine with a 2.54:1 reduction gearbox, it has four cylinders of 72mm bore and 84mm stroke for 1368 cm3, a 11:1 compression ratio and generates 115hp (86kW) at 2461 propeller rpm for 85kg (187lb) and a 215g/(hp⋅h) (288g/kWh) fuel consumption.[6]
In 2016, DieselJet was developing a 240kW (320hp) TDA CR 3.0 24V.[1]
