Am I incorrect that longer glow plug use in colder temperatures helps fire fuel (oil) to burn more fully . . . . and that oil warmed from 10 degrees or minus 0 temps to warmer temperatures allows the engine pistons to initially not resist movement like resistance of pure "cold weather engine oil" speeds so the injected oil doesn't cause chugging (initial over pumping of diesel into the cylinders that can't all get fired).
Isn't that - just like more throttle use - the reason multiple spins of the starter and more initial unburned exhaust are created and why the not-desireable chugging happens (engine resistance to movement and not full fuel consumption during start cycle) ?
After all - your starter on a gas or diesel can spin fast like crazy - but if the engine oil is slow to allow piston/cams/etc. from movement - you're "flooding" the cylinders with not fully burning fuel.
Just questions.
I agree with you. No idea why washing down the cylinder walls with raw unburned fuel doesn't bother the the block heater haters. Nor do they care about the knocking sound made by detonation on the compression stroke when raw fuel pre-ignites in the combustion chamber before the injector fires.
Maybe they can't afford the electricity however they can afford the increased fuel consumption and increased engine wear? There is no denying the prewired engine does not knock, doesn't wash lube oil off the cylinder walls, doesn't waste fuel idling to warm up and burns the fuel cleaner when started warm.
