The head is milled to increase compression ratio. There are several parts that need to be modified for things to fit afterwards, intake manifold, pushrods, and pushrods covers. The stock rod is adequate.
@balls2yourface The OS FS-48 engine is made for glow fuel (methanol, nitromethane, and lubricant) for use with a glow plug. I have converted this engine to run as a diesel. Model diesel engine fuel is typically ether, kerosene and lubricant, no glow plug is required, heat of compression ignites the air/fuel mix. Ether is there to assist starting and reduce running compression.
Can you show the conversion and the components involved in doing the conversion. I have a 120 Enya I would consider converting. I believe a diesel will spin a large prop than a nitro engine , but will the ideel be as low as nitro? My dads old Merlin used on the control line flyers was always a lot more robust and user friendly than the hair raising Cox motors we also flew.
I haven't tried a Saito. You must reduce combustion chamber size while making sure everything has clearance. The Saito may be more difficult to modify as it uses a cylinder jug.
do they make a diesel engine for cars or boats , can you run normal truck diesel in one of these engines or does it have to be the model diesel???? sorry for all the questions but after i seen all the plane engines running diesel im intrested in what all diesel rc engines have to offer
hi, i have a paw engine thats a 2 stroke, ive been running 1 part ether 1 karosine 1 corn oil, it works but i hate the smell of either and hope to use a fuel without either, and if i have to heat the cylinder with a torch before starting i would rather do that than put up with the smell of ether, will this work? also could i do like a 85% kerosine 13% oil and maybe 3% octane booster or something for better starting? last ? is a diesel 4 stroke have more torque than a diesel 2 stroke?
Would you care to show how did you achieve this? I mean like a tutorial!! I would love to get one of those large OS Engines to run on diesel! it would be like a dream come true! I have a FT300
Dear rcdieselrc I want to ask you:did you do any modifikation on your surpass engine to ıncrease the compression?Or did you buy a new diesel-head at OS-engines?Normaly the pleuel between piston and crankshaft nust be stronger.Did you change this too?Sorry my english is not enough and i hope you can understand me.bestregardsertan dileköz
Pump diesel won't vaporize well enough to run. I have tried, but with almost no result didn't pursue any further. It's possible with a purpose built engine, but not likely with a converted engine.
Basically there is no substitute for ether. My engines run on kerosene without ether once they are hot. Ethanol is a bad choice for the base fuel because it has a very high octane rating. Model diesel fuel is made with kerosene, ether, and lubricant oil. Kerosene can be substituted with other types of aliphatic solvents.
Ether has very little odor and is only present in fresh fuel. Ether quickly evaporates and dissipates. Without ether, the running engine and residual odor is virtually the same. You can try, but be prepared for a lot of testing and potentially broken engines. Octane booster is not what you need. Use cetane booster at 1-2% Even 0.2% change is noticeable. Use the same amount of oil as required by the manual. Four stroke engines can use less oil. In general four stroke engine make more torque.
Bowtie41 Just a small contra piston area, so a turn has much less effect than a two stroke where the contra piston is often equal to bore diameter. Racing diesels will have small diameter contra pistons to allow for finer adjustment.
I don't think it will have much impact on life when a good oil is used. Even so, the reduction in fuel cost would pay for a new engine long before it's worn out.

@horizonflyer9 That's a compression ratio adjustment I made for this engine. Model diesel engines typical have adjustable compression ratio.

Mine is doing fine. I have many hours on this engine. I've only worn out one diesel engine and that was the first on I owned, due to inexperience.
Dear rcdieselrc

what do you have to do to increase the compression? I really want to do this to may saito 50
Would I be able to run a 5cc model diesel engine using normal diesel from a gas station with a bit of diesel additive?
Pump diesel won't vaporize well enough to run. I have tried, but with almost no result didn't pursue any further. It's possible with a purpose built engine, but not likely with a converted engine.
+rcdieselrc Ok thanks, do you know of anywhere I can get some ready to use fuel?
These days I'm not even sure any more. I haven't bought any in years.
I would like to know, I can send the mechanical design of the conversion, or if you sell the piece ready.
What is that thing you're turning at the top of the glow plug area? I'm new to diesels
very smooth engine sound and startup, high compression right?
could you heat it up with a torch?

Was only thinking has anyone done this last night and this popped up
Something is reading are brains
all of your phone apps are listening
@@rcdieselrc must of been talking in my sleep lol
@m0dthunder Model diesel engines use model diesel fuel. They will not run on pump diesel.

Use the same amount of oil as required by the manual. Four stroke engines can use less oil. In general four stroke engine make more torque.
Compression ratio was increased to meet the requirements of the fuel. The connecting rod has not been modified.
Nice no glowplug shit necesary! Can u may send me a link how to make sucha conversion
That be so cool to put a 4 stroke diesel in a Savage X.
Is that a 4 stroke?
Yes
I'm guessing the screw on top of the head has VERY fine threads?It seems like you screw,and screw and very little happens,lol

Yes.
