I'm not going to argue with someone who doesn't know what a 2-stroke engine is. The term has been used in the US since at least the 1890's, you just don't know about it. Much like other induction methods for diesel engines beside turbochargning.

No supercharged diesel from the factory exist in the US from any of the Detroit 3.
Also what the hell is a 2 stroke engine? We don't use that term in the US..

GM/Detroit Diesel are probably the most well known with 2 stroke diesels state side.

All of which were supercharged , some turbocharged as well, they are fun. Detroit 71 series afaik. I think under some circumstances they were classified as being NA because they can't function without the blower. But they use mechanical power to force induction which is supercharged every day of the week imo.

No need to be a know it all. I've never once heard anyone use the term 2-stroke for cars/trucks in the US and i know a few mechanics.. Clearly you can supercharge a diesel engine(really any engine) and saying i don't know of that is ignorant of you to assume that.

Again never heard anyone ever use that term

No diesel in the US from the Big 3 are supercharged. Look at any of the websites.. Ford, Chevy, Ram. All clearly state turbocharged. Just like every other US diesel engine on the road. None from the factory are supercharged and if they are i would like you supply a link because i can't seem to find one.

 

[barnsley]

They mostly do engines for Frieghtliners but they made the standard engine for the H1, The HMMWV, GM's CUCV and a couple of others. Nothing super new mind.


So I'm guessing you've not heard of GM's 6.2L V8 Diesel? The one before the Duramax? That is a 2 stroke.
Currently the 2 stroke engine is more common in boats.

I never said anything about the big 3. You stated 'supercharged diesels have yet to appear in the US'.

Detroit aka 'Detroit Diesel' still trading as Detroit introduced the 71 series in 1938 which alongside the larger displacement 92 series remained in production until 1995. They were all Supercharged 2-stroke diesels utilizing a root style supercharger for induction as 2-strokes rely on forced induction. They were used in trucks, tractors, plant, commercial vehicles and power generation in the US for decades. They were succeeded by a 4-stroke Detroit in '95 which I assume was related to emissions and most probably noise requirements. (supercharged 2-stroke exhaust flows are supersonic, or in short awesome).

Sorry if I came across as ignorant. You did as well.

I'm gonna say one thing though, volvo make some awesome sounding diesels. Mainly because I like my diesels to sound like tanks, not some lame attempt at being a petrol.

Loads of tanks are petrol though i'm all for diesely diesels. Must admit i'd had my eye on 2.0D Volvo C30's for a first car, they seem a little more affordable than the german stuff, i'll have to go test some.

I know there are many petrol tanks, its just tractor didn't sound nearly impressive as tank.

I'm currently looking at (not super seriously as the Crusta has still got a year or so to go before it fails its MOT...again) a petrol 3 series, a Jag X type (diesel) or a Golf/Seat Leon Diesel. I kinda want a diesel now, I prefer driving them. In a dream world I'd love an old Volvo 240 Diesel with a turbo but as I lack both the building skill/a garage to work in thats pretty much off the cards.

I did not at all.. i'm not talking about 74 years ago. That's totally irrelevant to today's engines(the one's were talking about). Course if you want to be super anal and literal yes it is correct. They did exist 74 years ago. But then again the conversation was about modern engines.

Gasoline engines(performance engines) sound like crap compared to any big diesel engine.. Gasoline engines lack that deep growl. Diesel's have them just by being a diesel. Course you can change either to sound deeper however. I'm not sure if it's the same in EU but in the US it's quite a big difference in noise. So much so that it's not even difficult to tell what's a diesel or gas engine if your eyes are closed.. That big a difference.

You did, when you called me out on a subject area which I study both personally and academically and then backed it up with random claims and simply untrue statements.

Sorry but that's wrong. Diesel engine's in their nature are more efficient than gasoline engines by 15-35% depending on the engine. Take any similar sized engines(diesel and gas) and the diesel will always be more efficient. They do not need turbos to be effective. They need them because the gains are huge and fuel emmisions are at an all time high in the US so they need them to get the engine to burn as clean as possible.

The MAN S80ME-C7 low speed diesel engine is one of the most fuel efficient engines of its size on the planet. It is a diesel engine that uses only 155 grams of fuel per kWh of energy produced. This gives it an energy-conversion efficiency of 54.4%. A fuel efficient turbodiesel engine that is running properly can deliver as much as 30 to 35% greater economy than gasoline-powered engines of comparable size. One of the reasons for this increased diesel fuel economy is the fact that diesel fuel is denser than gasoline, although it does have a slightly lower calorific content. Something else that comes into play is that diesel engines don't have a butterfly valve in the inlet system to close of the air supply.

edit: Supercharged diesels have yet to appear in the US.. and i doubt they ever will in the foreseeable future.

I'm fully aware that we are discussing modern engines and that the Detroit Diesel (GMC) Supercharged 2-strokes went out of production 19 years ago my point was they were an extremely popular and successful line of engines, with many still in use in the US. And while technology may have moved on thermodynamic cycles have not changed.

When it becomes technologically possible to control the emissions of a 2-stroke and build them to meet todays performance requirements I honestly think it is likely they will appear in the US and global market again. But as I said before todays on-highway engine development is emission driven not efficiency driven.

Marine engines take a slightly different angle on things as in general they require a pretty constant power output over an extended period of time making efficiency a much higher consideration. And therefore they are some of the most efficient engines in the world, just like that MAN S80ME-C7 you quoted earlier, which I think you will find is a diesel 2-stroke.

As some of you may know, i like my cars low!

Today i discovered the bimmer is too low!

Here we have my jacking point, i ripped out just getting of my drive way, i knew sooner or later i would break something, ddint think id rip the jacking point out, so plan of action, move house so i have a nicer driveway and lower the car more

You hero! If you're able to go places its not low enough though imo

Read what they say on Wikipedia. That'll explain it more and will give some decent examples. This is the engine I give as an example of a truck 2 stroke diesel engine.

Would you class cars from the 90s as modern?

I can always tell the difference between the two, its just in the EU most diesel engined pickups/cars sound very tame in comparison to what you guys have.
-edit- looking at used trucks on ebay. I'm so jealous of you guys and your low vehicle prices

2-stroke makes little more sense now. Still never heard of it outside the forum

I would say they are modern, but technology wise i wouldn't classify them as being modern.

Ah that's why. Jealous? Ya our prices aren't cheap. Want a diesel truck? Ya that'll be $40k easily. Unless you go for the new midsize trucks(which are nearly the same size as the full versions) you can get a tiny ass 2.8l diesel.. and pay over $30k for.

What you would class as a 'small' truck with a 2 liter diesel would set back about $40k (£25kish). Used its not much better

Depends on the size of the truck i suppose. Though the engine seems little small but if the truck isn't heavy it shouldn't matter.. past few years the the truck market in the US has exploded and all trucks are getting major overhauls and vastly improving in every area. First that comes to mind is luxury"ness". All the leather seating and infotainment systems and just easier to drive(i don't like the new way they drive). All that and prices are going up but people keep buying them.. i almost had enough to buy my first truck but with the prices rising i won't get the one i want.. waiting for a used one now, so i can relate to you

Where is the best place to sell private number plates?

My Dad is giving away his 3 series BMW which is fucking mint, no way is he giving the plate away with it, I'll take the fucker off before it goes anywhere!

You need to get the plate put on retention, then sell the retention document on the bay of e

Whats the plate, if its interesting ill consider it?

 

[ShaunB-91]

I need to talk to my Mum, I'm really not happy about it being given away. I would buy it from him, even if its just to do it up a little in terms of the colour and then sell it.

The person he's giving it too will trash the fuck out of it, and its been kept MINT all these years, there isn't a mark on it apart from one tiny area on one of the windows were its bubbled.
