when i was runnning my diesels i had a doubt that why cant we use normal diesel which is available in fuel stations
if can one knows abt this let me know
and can we run run with that normall diesel fuel?or any recipes should be added in it

i guess,surely you can replace kerocene with diesel..
but diesel has much less calorific value than kero.So power output will be less.

lets wait fo some diesel guru

Avoid Diesel

a) It has a higher density
b) Lower calorific value
c) Will emit soot (carbon)

Model CI engines are not designed for this

Aditaya - what is your question ?

do you have a model diesel engine that you have run and
are wondering why you can't use normal HSD ?

If so - then what is stopping you from trying ? better you
try practically. You will not ruin your engine.

I have tried this when I was in class 8 or 9 and I soon found
out that the engine will not run.  As to why ...... NO IDEA ...!!

"Diesel" (model) engines are a bit of a misnomer. As sanjayrai55 has said, they are correctly called "compression ignition" engines.

"Regular" diesel engines are CI engines too. The term diesel became generic like "Xerox" for photocopy.

The high compression ratio required to ignite diesel would not be practical for model engines.

look at this ether less diesel engine........

This too does not use diesel as part of the fuel mix.

3 parts kerosene, 1 parts gasoline ,2 parts motoroil 15W-50
How this is discribed in percentage

3+1+2 (parts) = 6.

100(%) divided by 6 = 16.6%.

Each part is therefore equal to 16.6%. Ergo, 3 parts = 50%, 1 = 17%, 2 = 33% (rounded off).

Basic school level maths, I would think.

Long ago, we used actual diesel fuel instead of kerosene for model diesel engines. We used a 1:1:1 mix with ether and castor oil.

I understand that nowadays, kerosene is blue in colour due to an additive to prevent use in engines; it is subsidized for the poor for lighting and cooking. I would not trust the additive not to damage the engine in some way. So I suggest that diesel from the "pump", that is automotive diesel is actually better! It is likely to include a small amount of ignition-improver, though less than the ratio required for a model engine.

I happened to see somebody remarking that with diesel instead of kerosene we can use a bit less oil and a bit more of ether; could be right.

well..... they are all internal combustion engines..... one where the combustion takes place due to the compression of the fuel vapours (diesel engines) and in the other due to the spark / glow provided (petrol engines).
Diesel engines geneally use Kerosine, Either and Castor Oil as fuel in the ratio of 40:30:30 or 50:25:25 v/v.  The commercially blue kerosine is absolutely fine to be used for the engines.....  been using it regularly
Petrol engines generally use a mix of Methanol and Castor Oil as fuel.... Nirtomethane can be added to enhance performance but it causes high wear and tear due to high temperatures and higher RPMs

In case of any doubts contact Sharma Models as they manufacture the diesel engines and also sell petrol engines (glow plug engines)

These engines are too small to use the actual diesel or petrol as fuel as the compression ratios are not like their bigger brothers used on road worthy vehicles.

Simple answer: these are carburettor engines. HSD does not atomise easily and had to be injected
