Russian Revolutionary Hybrid car

[Dave Plowman (News)]

Rolls Royce did it in the early part of the last century. Called the Legalimit. It did have a three speed 'box, but in most circumstances could be started from rest in top gear.

True; diesel gensets run optimally at full load, but some will do quite well at lesser loads. Depends on the engine - some gen engines are quite old now and not updated much, but ECU control is taking hold there, just as in the automotive world.

[grimly4]

True enough, the Tu144 crashed first.

[grimly4]

The Russians didn't really think they were given the real plans, did they?

[grimly4]

That's why gensets are matched to the load. Small gensets aren't even in this picture - I mean 150KVA upwards to 1MVA, like wot I useter build. No point in supplying a hospital or copshop HQ with bigger than needed or one that's too small.

There's always gearing between engine and wheels, unless one is talking about non-IC engines - or the briggs & stratton flyer.

I tihnk its clear from the start this is not a conventional vehicle.

Indeed. Or where variable gearing is used and constant speed is used during hard acceleration - and with 40hp, nearly all acceleration will be full on.

Heh, no, I dont :)

Well they did get their maths correct unlike the Americans. Their first lithium bomb went off at 15 Megatons when they only designed it to be 5 Megatons.

The Tsar bomb was a three stage device IIRC, it was to have been a five stage device but that would have been 1000+ Megatons. It was decided that most of that blast would have just gone into space and was pointless.

Also the crankshafts as well. They are lighter, less metal and machining and balancing, not needing a heavy flywheel. They are at constant revs, the cooling systems are smaller as well. Magrius Deutz made 20KVA and upwards,

3 and 5 cylinder air-cooled genny engines - that worked well in deserts. Genset engines are far more efficient than engines that drive cars & trucks.

This Russian "rotary vane engine" promises to be highly efficient. Designing it for constant speeds will make matters easier all around and any problems associated with zero to max revs and directly coupled to the road wheels is eliminated. Cheaper to make as well. Emissions control is easier. It is cheaper to make all around as it is a quarter of the size and weight of current engines. A win, win all around.

The Tu 144 is still fly's, in various research roles, no Concorde is. These people put the first animal and man in space, the first vehicle on the Moon, etc. The MIG 25 was so fast the US could not catch it. The highly agile MIG 29 is one of the best designed air-frames ever. These are clever people. They have no need to copy, despite western propaganda telling us they are thick. They never put much into consumer items like cars and the likes not valuing such low tech items, putting their brains into other fields. They are re-focusing though.

BTW, the Ruskies make a Wankel type of engine that powers a helicopter. The V-12 engine that powered the T-34 tank in WW2 was far superior than any allied engine until the RR Meteor late in the war.

[Doctor Drivel]

The propaganda that the Ruskies stole the Concorde plans. Hilarious. In the 1960s no French or Brit ever got into space. That puts it into perspective.

[Doctor Drivel]

What crude electric vehicles might these be?

[Doctor Drivel]

Many here can't figure this out. All they had to do was understand the links I gave and maybe go further with Google. Then it is clear that designing a "rotary vane engine" for a constant speed, or maybe two or three set speeds, it will shine.

[Doctor Drivel]

Keep trying.

You are a very confused person. You should concentrate on getting your funeral policies in order.

The transmission was crap though - T34s often went into battle with a spare transmission assembly strapped to the engine deck. Contemporary British tanks were actually designed for the Meteor engine, but as it came off the same production lines as the Merlin aircraft engine and we were fighting an important air war at the time, none were available to put into tanks like the Cavalier and Centaur (which latter became the Cromwell when Meteor engines were available and fitted into them)

Why let reality get in the way of facts? Or should that be the other way round?

[Fredxx]

Why this engine any different to previous ones of the same design, which have failed to get to market? Perhaps it's efficiency and reliability.

Have you forgotten that it needs a petrol-oil mixture to lubricate the bores? Of course that won't pollute will it, certainly not in your eyes??

[Tim Streater]

Again, k*****ad - it never saw serious commercial service - as you'd know if you read the Wiki article.

[Dave Plowman (News)]

Strange that Toyota with the billions they have to spend on research use plain ol' conventional IC petrol engines in most of their hybrid models. Are you saying they've got things wrong?
