dit is nou regtig ploeg tyd van die 8ste april af gaan ons n bietjie diesel brand ,die planter is klaar gehak sal maar min tyd he vir vlieg tuig bou

Man moet werk ook. Ek het dieselfde probleem.

Hi Jaco

Great project and thanks for the updates.

Would a 1.6 / 1.4 diesel engine work with a direct drive ?

The diesel engines have in the region of 200 – 220 N/m at 1700 rpm and produce up to 80 hp.

We have locally the Ford 1.6 diesel and overseas the Mini ,Peugeot and Toyota are running the same 1.4 diesel engine and it weights 100 kg.

Apologies for the hijack

[JACO]

Off the top of my head I can't see any reason why it wont work. As long as you limit the revs
to keep the prop tip speed for your cruise rpm at or below 700 feet per second or 475 mph and
weight is not too much for the aircraft CG, it should be possible. There is a Toyota Diesel Flying
in the Cape at this stage.

Cheers.

t-bird are you directing your question regarding the diesel engines at me or at Jaco who is building a Toyota 1nz engine into a trike,his project is looking great ,and very affordable.
To tell you the truth i haven’t considered these small capacity diesel engines for a number of reasons,so I have not done a lot of research about their power and torque curves.But from experience most modern turbo diesels will run happily at 75 %load at 2500-3200 rpm so direct drive should be possible with the correct prop
Power to weight ratio is also a concern as I doubt that you would be able to bolt the prop directly to the crankshaft (axial and radial loads ect) so some type of extension housing with a carrier bearing will have to be used
To isolate engine vibrations from the air frame could also prove tricky ,there has been a big improvement with common rail diesel engines but they do not run as smooth as petrol engines
Due to the nature of my work ( Automotive engineering machine shop)I get to see a lot of engine failures most due to operator negligence not ad hearing to a service regime and some related to design problems . Abnormal combustion and over fuelling in tier2 and tier3 direct injection engines are normally fuel quality related
Electronic injectors and cracked piston crowns are not cheap to repair
Another practical consideration with inline 4cyl engines with direct drive ,depending on the application is the position of the thrust line on pusher applications this should not be a problem
There are a lot of positive aspects to diesel power who knows if the yaris project reaches a satisfactory conclusion I might be tempted to take up such a venture

After getting an ear full from boet i made this sanding block,which has become an extension of my arms over the last couple of days

Hi Diesel dog and Jaco

Thanks for the info. I have a gyro project that needs an engine.
914 is too expensive and uses 23/25 liters an hour.

The torque on the toyota/mini 1.4 diesel is double the 914 and weigh almost the same.

A diesel gyro would be the ultimate flying machine, but extennding the crankshaft would be a problem.

Subaru have a diesel but it is very heavy

My eyes are starting to deceive me ,put on some contrasting colour to make finding the low spots easier.

This just have to be the purdiest cowl for a Yaris engine ever. Diesel Dog you amaze me. I never knew you have a sculptor hidden somewhere inside.... Welcome for some more earfulls if you battle.

[Boet]

Mmmmm. En waar kry jy daai mooi spinner??

[Grote]

Verbeel my ek het onlangs ````n soortgelyke een by Loeriesfontein Aircraft Industries sien le

[diesel dog]

Boet dit lyk vir my asof een van jou handlangers dit spinner gemaak het want jy herken dan nie jou eie handewerk nie.jy moet daai man n klop op die skouer gee die spinner is pragtig/

[diesel dog]

By the way BOET waar is my faktuur jy weet mos ek hou nie van skuld nie

[attachment=I went to the airfield this morning and flew the Jabi ,beautiful conditions hardly any wind, nice break from sanding.But I kept on thinking of the cowl plug I was making ,it looks good but feels like the inside thigh of a mature woman or maybe a ripe watermelon.
So when I landed I scrutinised the Jabi with my eyes closed,ripe watermelon for sure ,
Are my expectations un realistic for a hand made composite cowl.
The plug is now ready for spray filler
If I remember correctly from art history the impressionist movement believed to make bold brush strokes and not to rework your creation to much.

No that is not fire ,just amusing myself with some old spray cans ,sanding can become a lonely job

This is the last time we will see the cowl plug , going to pull mould next ,working late is starting to play mind games with me I could swear I heard music tonight coming from beneath the cowl .I WANT TO BREAK FREE , I WANT TO BREAK FREE.I think i should lock up now and go home.
