Some modern ones now feature a throttle-plate, even though it's for emissions compliance instead of cold-start concerns. On a sidenote, fitting an extra glowplug to the intake elbow of some older engines is also not unheard of.

Drive gently and even climb a hill if you need to get heat into the cabin.
Got me to remember the day a friend who was not so used to Diesel engines told me quite surprised about a bus driver who kept flooring the throttle pedal right after a cold start in order to raise the temperature quicker.
