The Importance of an Engine Block Heater on a Generator
An engine block heater can be a vital part to a generator. See in our video above why it’s important.
The engine block heater on a generator set basically keeps the water in the engine (the jacket water) warm. Usually around 100 degrees. It’s not so much that it stops the jacket from freezing, but it’s a great starting point.
Diesels love to start when they’re warm (cold not so much). They really are warm blooded beasts. And by convection it actually warms the oil in the engine as well – in the crank-case.
That’s going to add to the oil pressure quicker and it’s going to make the engine run longer because when that engine starts it doesn’t ramp up to speed. It comes up to 1800 RPM fast – almost instantly. When that happens there is no oil on the main bearings, the journals, everything is just getting worn until that oil moves around.
When the viscosity of the oil is lower it’s going to build oil pressure faster with a warm jacket and with that convection going on you’re going to save your engine many hours.
