Engine Oil For 10000 Km

[Orestes Hardy]

Personallyall I use is a hay filter. My truck has nearly 20,000 miles on woodgas, and showing no engine problems. I expect the gasifier will be replaced multiple times and the truck junked out before the motor wears out.

Adding and maintaining a bunch of filters would have cost me time and aggravation, and made zero difference to my woodgas miles traveled. For my use, and my fuel supply, the current setup is working beautifully.

The LNER W1 No. 10000 (also known as the Hush-Hush due to its secrecy) was an experimental steam locomotive fitted with a high pressure water-tube boiler. Nigel Gresley was impressed by the results of using high-pressure steam in marine applications and so in 1924 he approached Harold Yarrow of shipyard and boilermakers Yarrow & Company of Glasgow to design a suitable boiler for a railway locomotive, based on Yarrow's design.

The boiler was not the usual Yarrow design. In operation, particularly its circulation paths, the boiler had more in common with other three-drum designs such as the Woolnough. It has also been described[by whom?] as an evolution of the Brotan-Deffner water-tube firebox, with the firebox extended to become the entire boiler.

The boiler resembled two elongated marine Yarrow boilers, joined end to end. Both had the usual Yarrow triangular arrangement of a central large steam drum above two separated water drums, linked by multiple rows of slightly curved tubes. The rearward "firebox" area was wide and spanned the frames, placing the water drums at the limits of the loading gauge. The forward "boiler" region was narrow-set, with its water drums placed between the frames. The space outboard of the tubes formed a pair of exhaust flues leading forwards. A large space outside these flue walls but inside the boiler casing was used as an air duct from the air inlet, a crude rectangular slot beneath the smokebox door, which had the effect of both pre-heating the combustion air and also cooling the outer casing to prevent overheating. Longitudinal superheater tubes were placed between the steam generating tubes. The third area forwards contained superheater headers, the regulators and the smokebox. The external boiler casing remained at much the same width throughout, giving an overall triangular, but curved, appearance. The lower edge of each section stepped upwards, and was obvious externally.

The heavy forgings for the main drums were built in Sheffield by the John Brown shipyard.[1] The boiler was constructed and fitted to the frames by Yarrow in Glasgow, involving the rolling chassis being carried over the LMS, carefully sheeted over to avoid inspection by a rival railway company. This chassis was a 4-2-2-4 at this point, as the centre drivers and rods had not yet been fitted. The first works photographs, with the boiler cladding in grey, were taken in Glasgow, with a wooden dummy centre driver and coupling rod added for the photo.

This apparatus was based on a Gresley Pacific 4-6-2 chassis, although with an additional axle to accommodate the extra length. This resulted in a 4-6-4 wheel arrangement, making No. 10000 the only standard gauge 4-6-4 tender engine to run on a British railway (although there were several standard gauge 4-6-4T classes that ran in Great Britain).

The high pressure necessitated compound expansion; steam being supplied to the two 12-by-26-inch (305 mm 660 mm) high-pressure inside cylinders and then fed into two larger 20-by-26-inch (508 mm 660 mm) low-pressure outside cylinders before going to exhaust. High-pressure cylinder diameter was subsequently reduced to 10 in (254 mm). Gresley incorporated an ingenious unique system for giving independent cutoff to the high-pressure cylinders using only two sets of Walschaerts valve gear derived from the outside cranks on the Von Borries principle[2] and using an inside half-length expansion link.[3]

The locomotive was completed at Darlington Works in 1929. It had a corridor tender and ran non-stop London to Edinburgh services to time in 1930; nevertheless steaming was relatively poor during test runs, and in spite of a number of modifications initially to the exhaust, boiler performance never reached the standards of an equivalent firetube boiler. A problem never fully solved was air leakage into the casing.[4]

The corridor tender was similar to the ten built in 1928 for those locomotives of classes A1 and A3 that were used on non-stop services such as the Flying Scotsman. The 1929 tender differed from the 1928 tenders in a few details, such as being provided with disc wheels instead of spoked, and having the in-curved front ends of the side sheets finishing 7 feet 10 inches (2.39 m) apart instead of 6 feet 11 inches (2.11 m), in order to suit the W1 cab as opposed to the A1/A3 cab.[5]

No. 10000 never carried a name, although it did carry small works plates on the smoke deflectors bearing the number 10000. In its early form, it was known unofficially as the Hush-Hush as a result of the initial secrecy surrounding the project, and also the Galloping Sausage as a result of its bulging boiler shape.[8] Plans in 1929 to name the original engine British Enterprise were dropped, although nameplates had already been cast;[9] a 1951 plan to name the rebuilt engine Pegasus did not come to fruition either.[10] During a works visit in May/June 1948, the corridor tender was exchanged for one of the non-corridor type, and it was given British Railways livery and renumbered 60700.[10]

On 1 September 1955, 60700 had just departed from Peterborough when the front bogie frame broke. The locomotive derailed at a speed of 20 miles per hour (32 km/h) at Westwood Junction. It was recovered and repaired.[11]

60700 was withdrawn on 1 June 1959 and was broken up for scrap at the Doncaster Works later that year. The first of its two tenders did survive into preservation. Corridor tender No. 5484 is now attached to No. 4488 Union of South Africa.[7][5]

In January 2020 Hornby Railways announced that it would be producing a model Hush Hush/W1 in both original and rebuilt forms in 00 gauge covering the locomotive's lifespan. These were original condition as No. 10000, original condition but with the British Enterprise nameplates that were cast but never used, original condition in LNER apple green as seen on collectible cards of the time, rebuilt LNER garter blue and rebuilt in BR green with early emblem as No. 60700. In January 2021 three more versions were announced, including original condition but with a double chimney as No. 10000, Rebuilt in LNER photographic grey, and rebuilt in BR with late crest as No. 60700. Previously the model was only available as a metal kit.

We've reached the 10,000 mark for monitored network elements and I've read that you should start looking at additional polling engines (APE) after 10,000 elements, as you could experience performance issues etc. We have a central deployment which we don't want to stray away from, I just want to add the additional engine for load balancing purposes to prevent it becoming slow etc.

We have two additional polling engines and use NPM, NCM and SAM. Both of the additional polling engines are on seperate servers. I can't see how you could do it any other way as you select which polling engine to use by server name.

Yes you require an additional polling engine license at an additional cost. I would guess pricing is different for Countries/Markets/Sectors etc so I couldn't speculate on what you would be quoted for price. But for a ballpark figure, one of our additional engines is not too dissimilar in price to the NCM renewal.

NAM was a good fit because it added UDT to my environment, which saves me loads of time. It also is being mined by my CMDB so the Help Desk and other IT staff can predict / know which users and devices will be impacted in case of maintenance or unexpected outage to any switch or router or firewall.

NAM also got me the ability to instantly install up to 20 APE's at no extra charge, and I'm up to seven pollers now. The limitation is 100,000 elements per NPM instance. I hope to be retired before I reach that number of switch ports.

The need for additional servers, whether VM or stand-alone, depends on the resources allocated to the APE and the amount of polling it's doing. For example, in one of my remote regions, the VM environment doesn't have the CPU / PROC speeds or RAM the APE's need. Monitoring the VM hardware hosting the APE guests reveals that adding an APE to that VM Host will only stress it further. I'd already seen it was running at 100% CPU for a while; when I contacted the VM Admins about it, saying I needed another APE as a new Guest on that Host, they built it quickly for me. And then promptly let me know that the Host wasn't able to provide all the resources the various Guests required. They're suggesting I go stand-alone servers for more APE's there, until such time as their team is allocated budget sufficient to the needs of replacing or adding more VM Hosts with more/bigger/faster procs and RAM.

If receiving sufficient budget for the right amount of APE's and hosts in which to install them is an issue, there are ways to get budget. Even if you've been told "no" previously. Solarwinds has a great video out about it, and I reviewed it and they were kind enough to publish my Guest Blog about it here:

Read through it, check out the comments--there are great thoughts shared in it, and some of them may get you to the place where you can have the right amount of licenses and tools and APE's for your environment to thrive.

If you need to create or modify the mesh frequently use the UProceduralMeshComponent. Once this work switch to RuntimeMeshComponent (GitHub - TriAxis-Games/RuntimeMeshComponent: Unreal Engine 4 plugin component for rendering runtime ge -> Look at URuntimeMeshComponentStatic) for optimal performance.

If unreal freezes check your Task Manager if the unreal engine process still utilizes CPU. If yes it does things in the background. Than you should either run your editor in debug mode and add a breakpoint along the way. Also you can write to the log. Even if you have to kill of the process you will see in the Output Log (Window->Developer Tools->Output Log) the entries of your scene.
