ANY engine built with "pre combustion" chambers will require pre heat to start promptly even in the tropics.

Once warm they will usually fire off with out the heat.

Pre combustion chambers is chosen for better fuel economy and less diesel rattle underway.

An OK compromise of complexity for the advantages.
