Smart Turbo Diesel or VW Lugo Diesel
Montblack wrote: ("bbutlergps" wrote) I am looking into a power plant for a Zenith 701. I am very interested in going the route of a diesel. I like the Toyota (Yaris, and other models) 1.4 D-4D (ALL Aluminum) Turbo Diesel engine I'm having trouble finding a variety of good links to the engine's specs. Toyota .................1.4 D-4D Horsepower ........90 @ 3,800 Torque ...............190 @ 1,800-3,000 Weight ..................99kg (weight includes many extras: turbos for one) From the below link: "...VVT-i continuous variable valve timing although Daihatsu called it "DVVT" instead (D for Daihatsu?)" This is on the normally aspirated 1.3 model. I suspect the 1.4 D4-D is also DVVT --- which is a plus for Sport Pilot applications, since constant speed props are out. http://preview.tinyurl.com/y75lou (Same link as below ...wait for it) R.A.H. April 13, 2006 "Toyota (aluminum) Diesel 1.4 D-4D ...89 bhp" http://groups.google.com/group/rec.a...d5049bec028d5b http://www.geocities.com/plane_diesel/index2.html Good info on the Toyota Ya(n)is 1.4 Turbo Diesel engine In conclusion: 1. Toyota 1.4 D4-D should be able to turn a prop at 2400-3000, WITHOUT needing a PSRU. 2. Direct injected Turbo Diesel will do well with this LSA requirement: "A maximum airspeed in level flight with maximum continuous power (VH) of not more than 120 knots CAS under standard atmospheric conditions at sea level." 3. If it's a single seat LSA, the weight penalty is not as much of an issue. 4. Throttled back to 2400rpm, I would think the 1.4 D4-D would cruise around all day @ (under) 2 GPH ...just a guess. g 5. Turbo cruise would mean Sport Pilot/LSA flights @ 8k-10k ft might see 140-150 kts (GPS) ground speeds. ...just a guess. g Montblack-smoke-out-the-exhaust-pipe Montblack, Thanks so much for this type of information. Are you in Euro? Keeping it coming. Thanks again, Bill |
