Some things we must bear in mind here. For those of you who don't know too much about diesels, and how they work, these engines don't have cold start devices like glow plugs. They rely entirely on the heat built up on compression to ignite fuel. So this is why sometimes on a very cold engine, it only fires on 1 or 2 cylinders to start with, until the rest get hot enough to ignite the fuel. This is also why there is so much white smoke, which is unburned fuel, and is further the cause of the knocking noise. Once all the cylinders actually are firing, all the knocking stops, and most of the smoke too. Those who are saying it was/is knackered, are very wrong.

why don't they have glow plugs?
@philippartridge95815 жыл бұрын
Chiefly - the valenta was originally a marine engine still used in some royal naval ships. It's a large engine that uses high compression. In a marine environment the engine would have been turned over by air to build up heat before diesel was injected in. On the HST it lacks a continuous steady air supply. Therefore relies on an electric starter to do the donkey work of getting the cylinders and engine upto temperature.

chiefy1402 : no glow plugs for various reasons. Designed to run all the time, not like a car in personal use. No need really as it works without as you can see here. Glow plugs for this size to get a big fella hot would require massive electrical currents, you need massive batteries to provide that. Size, weight, cost... there we go, can do without.
@Dokker624 жыл бұрын
Big diesels are usually not fitted with any kind of cold start equipment and supposed to be pre-heated as glow-plugs could not create a steady ignition in large cylinders like these at low temperatures. Therefor the whole engine block needs to be warmed up by heating the coolant. British bollocks however just crank their stuff till the bitter end as they commonly have no clou about engines.

I worked with the marine version of the Paxman diesels used for the main generators. They were honestly unreliable and difficult to work on. The issue's got so bad that they replaced them. Ive never seen that before or since. These diesel were supposed to last the life of the ships they were on. The Lister Blackstone diesels that replaced them were much better. easy access to regular maintenance items. The Paxmans had such a bad reliability record an extra engineer was onboard and his sole job was to keep them running.

Although it can be heard here, it's not as obvious as some Valenta starts I've heard which is a 'clunk' as the engine starts to fire after the whining priming has been done. There's that whining for a few moments or even minutes, then there's a short 'clunk' and the engine starts to turn over. I don't know why but I just love that second between the priming and the engine firing with that 'clunk'. I don't know what or why that clunk is, perhaps someone who understands what I'm on about can enlighten me.

@beeble20033 жыл бұрын
Diesel engines don't have spark plugs. The fuel ignites because compressing the air in the cylinder makes it hot enough to spontaneously ignite the fuel when it's injected. However, when the engine is cold, the air doesn't get hot enough and the fuel is cold, too, so it doesn't ignite and gets pumped out of the exhaust. As the engine block starts to warm up, the cylinders start firing, one by one. The sounds you hear are just the normal sounds a diesel engine makes when it's running, but you don't normally hear them because they're masked by the sound of about 75 explosions per second when the engine's running at 1500rpm and all twelve cylinders are firing. Engines that are designed to be started in cold conditions have heaters installed in the engine block to avoid this, but it doesn't get cold enough in the UK to make this worthwhile. Also, these engines were designed just before the 1970s oil crisis, so the intention was that they'd be left idling 24/7, especially in cold weather, as diesel was super-cheap and climate change wasn't on the radar.

I wonder whether this is representative or was a knackered / faulty engine. I would have thought that the media would have been banging on about the pollution if this was a normal occurence. Even for an engine without `glow plug' preheating this sounds & looks terrible! It can be seen why MTU engines were necessary to clean up the IC125 for the 21st century. Notwithstanding the above the Valenta sounds great once hot.

+Simon Swain I noticed that just after 1.45 the engine at least started to sound more normal and the knocking had gone. Just as an aside it's amazing how poor the MOT is for Diesel engined cars in the UK, my 2006 Vauxhall Opel Astra 1.7 can smoke really badly due I believe to sticking vanes in the variable vane turbo. Yet, luckily for me it so far passes easily the on / off accelerator test used in the MOT. Whats needed in my view is a rolling road test to expose this type of fault (gradual increase of accelerator under load causes smoke). To stop it smoking excessively I drive it in a heavy footed fashion from low engine revs, this opens the (sticky) turbo vanes fully until the revs climb & then the vanes are progressively closed under the dictates of the air flow meter & inlet manifold pressure sensor.
@austinshackles5498 жыл бұрын
We don't know how cold it was, of course. None of the older power units like this had preheat or other cold-start devices, and in very cold weather it'll take longer than 3 minutes or so to get warm enough to run clean (well, as clean as a valenta ever ran, which was not all that). As for "why re-engine the fleet" it's a damned good design all round, but the engines by the end had been in service for 30 years and covered millions of miles each and were worn out. The Valenta was also prone to self-destruct, and supplies of spares were running out, and Diesel engine design and fuelling had, by the end of the 20th century, changed quite a bit. So new, more efficient engines needed to happen anyway. It farts and bangs to begin with as, like all well worn diesels, not all the cylinders and injectors are equally worn, so it starts on probably only 3-4 cylinders and the others gradually chime in. I've got a 3-cylinder 1970 or so tractor that does the same, one cylinder doesn't start firing til well after the others, even with new injectors in it. The backfire/flames is due to build up of unburnt fuel in the exhaust from the cylinders that are slow to pick up, once the exhaust temperature gets high enough it lights that fuel up.
