Lucky you, that happened to me at 30! Can't remember what it's like to not feel tired.

Do you have a link that might be better than what a search engine throws up? Thx

PM 10 most definitely does not lodge in the lungs. They do not go past the larynx. PM5 may or may not. PM3 and below does. Funny how SI chucks out loads of PM1 and UF but no one cares. UHC and other VP compounds are loaded on the PM surface; the P itself is not UHC. Liquids don't turn into solids during pyrosynthesis.

That might explain the issues Subaru have had then. 10% is ridiculous, unacceptable. Ww's 20% is insane. Isuzu put an injector into the DPF atleast as far back as 2006 I know that; on the Z30DT engine so why not in this particular application?

My "100,000" miles posted earlier was conservative! Over that 2% will reduce lifespan from 75000 to 30000, or 750000 to 300000 and so on. Sorry.

Woodworks: nothing like as bad as gasoline dilution but bad all the same. Gasoil does not hold up MOFT in bearings or cams. I will go and unearth my old idgte lecture notes Reduced viscosity, flashpoint, etc. Excess of 2% is considered severe.

IMO; that motor is a scrapper. The fuel dilution will have taken the lifespan down 100,000 miles. Nightmare.

Assad, Saddam et al were / are moderate with the benefit of hindsight.

Oh dear..............................

Constant volume is a crap concept full stop though.

Answered perfectly below. There is a worse paper. The Mirror.

You are right about constant volume (SI) vs constant pressure (CI). Pure adiabatic compression to serve the carnot cycle; that is what RD was concerned with. Akroyd Stuart was the sparkless ignition man. However, the system of injection build up and subsequent multiple injections, somewhat irrespective of pressure (altho that is needed - the term is "injection hardness" - particularly in a DI) is designed to maintain that constant pressure, hence greater torque outputs without higher bmep. So no, greater oxygen density isn't designed purely to decrease flame propogation time and a reduced CR will permit this. The idea of higher Inj pressure is merely to reduce droplet size and therefore improve mixing. Re SI having all the oxygen neccessary for a complete burn - not at all; they might have been pushing lean burn for years but probe a SI engine exhaust (vs a CI) and you'll observe considerably higher UHC and even ultrafines. CI PM derives from fuel ash content; C as a survivor from the fuel would be be termed UHC in the vapour phase, not PM phase. This is pre-aftertreatment of course.

yep...

Certainly not rich of it (Lambda 1).

Funny. I've put a good 1000 ton through my circular saw (Japa) and it's only just starting to lose it edge.

Scottish, Welsh, Irish ?!

Early to bed, early to rise...

Cooler will halve the charge temperature. It's not a "charge" but you know what I mean. Idi or di engine? Cross flow head? Compression ratio? Increased density reduces ignition lag so smoother and quieter.

Remember the Perkins Prima 2.0 fitted in Rover Montego, Maestro et al? If only they'd intercooled it... that would have removed that engines "issue's" perfectly.

I had the same engine in a T180 Avensis 2008. Nice motor. Comes with DPF. No injector seal issues, more head gasket I think. Injectors themselves may have been recalled or re-flashed as Toyota call it. Check it's been done.

Sums my thoughts this morning right up!

Oil pump pressure relief... first thought...

Do you mean 600m3 of roundwood INTO it or 600 cube of loose logs OUT of it? Also, is that volume done in a big hit for storage or in a more leisurely fashion over the year? Green or seasoned in the round? Some very unglorified machines will do that vol peasy. Diameter of roundwood a slightly major factor.
