It seems all prechambered engines have glowplugs and (almost?) none direct injected diesel engines.This article could use some clarification.Wdl126.96.36.199 (talk) 20:14, 28 October 2008 (UTC)
My diesel needed one plug in 180k miles.Old d. used a little more.Wdl188.8.131.52 (talk) 01:45, 30 October 2008 (UTC)
What seems to justify the claim that large diesels don't require glowplugs? A good portion of the construction equipment I see is still equipped with them. The entire article seems to be intoned as if they're out of date.. it's pretty hard to get a diesel to start when it's 20F out without block heating, charge air heat, or glowplugs. If it wasn't for ether, it's near impossible. 184.108.40.206 (talk) 02:05, 21 January 2011 (UTC)
Are you sure large diesels require glowplugs? (by large diesel, I mean a ship's engine, like on a supertanker) 220.127.116.11 (talk) 14:28, 26 June 2011 (UTC)
This article should mention alternatives to glow plugs such as grid heaters. It seems like grid heaters are used on many larger diesel engines. (Entropy7 (talk) 18:57, 12 December 2011 (UTC))
I don't know about the USA but, in the UK, direct injection engines are not fitted with glowplugs. As a result, they can be very difficult to start. Here is an example.Biscuittin (talk) 10:08, 6 July 2012 (UTC)
Depends on how cold the engine was and how hard you're going to drive it. It never hurts to allow the engine and its oil to come to operating temperature gently, before working it hard. OTOH, it's generally held with modern oils that this is best done under light load, rather than slowly under only an idling load.
None of this is relevant to glowplugs. They're about starting, not warming up once running. Andy Dingley (talk) 11:04, 28 April 2014 (UTC)
