Yeah. Two Buick V-8's roaring away at redline, shooting flames from the straight headers will do it every time!
Starting fluid
- Thread starter CYQK
- Start date
Source please. All of the warnings I have read re. cylinder head damamge relate to diesel engines. Perhaps you heard this backwards.
Obviously, any engine can be damaged by overdose, if by over rev alone, but the octane of diethyl ether is such that a gas engine can run on it safely for very short periods, with no risk of pre-ignition. Obviously, you need to follow the instructions. Using brake cleaner or wd40 is off the reservation.
That said, I sail in sub freezing weather, and a few pulls is all it takes. If you need starter fluid, you need to fix the problem.
For starting a diesel with WD 40, I have no experience. I really was not responding to that. I was referring to starting a gas engine. My reason is that WD 40 is not marketed for either purpose and there is limited information available about the composition of the propellant, and by extension, its octane or cetane rating. Starting fluid blends, on the other hand, have been studied for these uses. We simply do not know enough about it.
I saw those on a cadet trip to Beal but this is the action I was thinking of.

I wonder how many Watts, or how many BTU/hr you need to really make a difference starting a diesel with hot air; and whether my plastic intake air silencer could stand it! (I really don't need it, but just curious.)
I am thinking something along the lines of this inlet air heater would be easier than a hair dryer.

About 10% of the cost. But, I wouldn't have to ponder who is cranking the engine and who is blowing it with a hair dryer.A hair dryer probably costs less!
Have been told ...dont spray this in,dont spray that in,to help start a high compression diesel engine
For my question what can you spray in a 50hp 4cylinder diesel engine to help it get started without blowing the cylinder head off
Thanks

Good clean diesel fuel.
Are you talking about special conditions like it’s 30 below zero and the engine is cold?
If the engine is functioning (good compression) and the fuel system is properly working (injectors spray properly) then all you should need is air in the intake and a battery to turn the starter.
Spraying in anything is a crutch because the other parts are not working.

john is 100% correct.
my engine is very old. i have had fuel line air leaks a few times over the 47 seasons of ownership.. (not now i hope) chasing those leaks was tough. having the engine running helped chasing down the leaks. most times my engine was acting up it was slight leaks of air. finding them can be difficult.
running the starter more than 5 seconds will lead to buying a new starter. bronze fittings on and off many times can lead to over tightening and stripping if your not care full. is it the pump? is it the injectors? is it goo? ............ some times if the engine was just running i could narrow down the issue.
dad bought a new ish top of the line vessel way back when. everything worked great. then these 48 years later, it ain't new any more. i have refreshed may things many times. my records at my local diesel shop go back to 1980. what was rebuilt and when.
i have used starting fluid. never had issues.
my yard uses starting fluid on other boats. no issues
i researched using such and found no issues
running your starter more than 5 seconds and then not letting it cool down has caused issues. new starter please?
what can you do? i always heard starting fluid was bad. researched it some. i found no proof of such. but that's just me and my studies.
hourly fees at my yard go up to $139.00 june 1st.
diy is great. keeping old engines running is an art form.

A significant reason you hear not to use SF on a diesel is most deisels ( in vehicles) now have flow plugs or screens that are red hot when you crank and spray the fluid in which causes combustion when the cylinder is not in its compression stroke and/or TDC. I’m sure there are other reasons with modern engines but this is a significant one.
This is it. A diesel gets hot through compression and the fuel ignites. Injectors are timed to fire only at the right moment, where as starting fluid is going to fire on the up stroke, with the pistong still going up, as soon as it is hot enough. Additionally, instead of burning as it injects, it will detonate (which is different from burning), going off all at once. Most fluids are very high octane, which reduces the detonation problem, but does not eliminated it. This is why you don't want a flamable mixture in a diesel intake; they work on a different principle than spark ignition.

You were writing as i typed that last one
Thanks for a good technical explaination
Guess the main thing is not to overload on the intake

i would listen to thinwater. he does his science. i have gotten away with it a few times. hoping to not have to ever again.

Find the root cause of the problem...
We routinely start out heavy equipment in sub zero temps with no starting fluid. Caterpillar D3 Bulldozer, Caterpillar 320L Excavator, Yanmar 35 series excavator Kubota Tractor, Ford F550 Powerstroke diesel etc.... if the engine is in good running condition there should be zero issues starting it in any temp above 32F..
