Products

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 118 kW (160 hp) at take-off and 107 kW (146 hp) continuously at 2450 propeller RPM for 205 kg (452 lb).[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 190 kg (420 lb), 121 kW / 165 hp maximum and 110 kW continuously till an 8000 ft critical altitude and a 225 g/kW/h (0.370 lb/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 142 kW (193 hp) continuous and 160 kW (217.5 hp) at take-off at 2306 propeller RPM for 219 kg (483 lb).[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 83 mm and 90.4 mm strokes, a 16.0:1 compression ratio for a 210 g/kW/h (0.35 lb/hp/h) min. brake specific fuel consumption, its manufacturer claims 205 kg (452 lb), a 8,700 ft critical altitude and operability till 35,000 ft.[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 115 hp (86 kW) at 2461 propeller rpm for 85 kg (187 lb) and a 215 g/hp/h (288 g/kW/h) fuel consumption.[6]

In 2016, DieselJet was developing a 240 kW (320 hp) TDA CR 3.0 24V.[1]

gollark: some languages have grammatical gender which is vaguely weird.
gollark: Well, in English we made it sort of optional, at least.
gollark: Idea for pronouns for baidicoot: emuwaronlinewhen/emuwaronlinewhenen.
gollark: Also, Emu War Online WHEN?
