For those with block heaters

If your John Deere 410J doesn't have glow plugs, it might be because diesel engines use a process called compression ignition to ignite fuel instead. In compression ignition, fuel is injected into the combustion chamber while the air is being compressed.

I can hardly believe that this was posted on these forums.

Perhaps I have missed something in this thread.

CalG - for some this site could be a major learning process. Hopefully.

1 hours always worked for me for the Case/IH that hates anything below 35F.

It may have been mentioned somewhere earlier. We don't live in a too cold climate. My TC45 has started no matter what temps it's in and I let it warm up much longer. Am I harming it in cold weather in this way?? Know nothing about them.

The design of the diesel engine is compression ignition. The fuel ignites from heat produced from compressing the air to high pressure. The cold combustion chamber may not allow the fuel/air to get hot enough to combust. A cold engine will benefit this process if the combustion chamber is heated (glow plugs) or the incoming air charge is heated by an element. Sometimes, hot air from a hair dryer directed into the intake might help to get it started. A block heater getting the engine a bit warmer may help too. A warm engine will normally spin faster when cranking which helps too.

It's really surprising how just a little warmed air into the intake will fire off a stubborn engine, gas or diesel. I have a Kawasaki V Twin on my walk behind mower that gets real testy at 40-50 degrees F, and a few minutes worth a fan heater in front of the intake gets it going with 2 pulls.

… and cold hydro oil only adds to the trouble, for any machine with a direct-drive hydro pump. Especially zero turns, as they’re usually spec’d for hydro oil based on an assumption of warm weather operation. My Deere 757 ZTrak is spec’d to run 15W-40 in the hydro pump, and it is a bear to start in a cold shed after Christmas, when I cycle thru the annual maintenance on all my OPE.

I often end up firing up a jet heater in the shed, to warm it up for 30 minutes before that cold start.

I run ATF in my log splitter, which starts much easier in cold than any single-weight hydro oil. But with a big 20 GPM pump, it’s still not an easy pull, when it gets cold. I actually ended up installing electric start on it.

a process called compression ignition to ignite fuel instead.

Instead of what?

There is an outlet on the outside. My 2 questions are:

How long do you leave the heater running before you start it?

How well do the digital or mechanical timers work when they get really cold?

I’m in NE British Columbia. Can get bitterly cold here. I use a mechanical timer that plugs into a regular wall outlet. Don’t use a GFCI type outlet, they nuisance trip frequently. When the vehicles haven’t been plugged in I have found that 2 hours is sufficient for the block heater to do its job in temps down to -40. At that temperature you should just stay inside by the wood stove anyway.

Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a gasoline engine or a gas engine(using a gaseous fuel like natural gas or liquefied petroleum gas).
