This thread is about the glorious Diesel engines such as;
Indenor XD 4.88
Ford 4AB
Mercedes OM602
Datsun SD22
Isuzu C190
Perkins 4.108
Please share your experience with these engines or similar.
Only rule is no turbo, coal burning, or electronics allowed.
And no VW shits.

what the hell is your god damn problem?

Because turbos take all the fun away.
>>14838675
Diesels are glorious. But a diesel engine is just not complete without a turbo.
NHC 250 is non turbo. 14l of fury.
Running twin turbo on a big cam nhc250=too much power.

Have fun doing 0-60 in 20 seconds.
3 litres of based 5 pot NA fury and hatred. Fucking piece of shit sounds like a badly tuned tractor. Not sure if I like it or hate it.

Yes as little as i know about diesel engines i was under the impression that if you wanted any kind of speed at all you needed a turbo
>>14839541
This is correct

Dodge Charger with Cummins Turbodiesel swap
This triggers the OP

Twin Turbo is even better. The BMW N47 in the 123d puts out 204bhp from a 1995cc engine. and a simple remap makes it put out 260bhp.
Pretty good from a rattly diesel.

i had one of those and couldnt kill it, literally sat on the limiter from california to washington and back, purred like a kitten when i got back. extremely strong motors.

Duck you OP!
Every diesel truck I've driven and every diesel tractor has been turbocharged. Hearing the turbo spool up on a tractor means some serious shits about to go down.
And a Case I6 Turbo diesel WOT still sounds amazing.
The fuel itself is just so viscous that it doesn't vapourise and atomise effectively at higher RPMs.
That's what limits RPM and hence power so much in diesel engines. Not so much the heavier reciprocating components to deal with the higher compression.
It's just inferior to petrol, unless you want fuel economy. See the various companies trying to make HCCP work
But muh torks! At very usable revs you say. Thing is a nice big petrol engine will have low down torks too AND will scream when they get to higher revs
>>14844102
Right. So all the semi trucks and large stationary engines like pic related are burning diesel for economy?
Do us a favor and remove yourself.
>>14844331
well yes, they are
>>14844342
I'm going to need proof on your claim then.
>>14844102
Not sure that is the reason for the limit to engine rpm in diesels.
It's because of the combustion process. In petrol engines, there is a single flame front, and the effect of increased in-cylinder turbulence speeds up the "turbulent burn" phase of the combustion process.
Increased engine rpm (and swirl) increase turbulence, so the speed of combustion and heat release increases with engine speed. In petrol engines, as the engine speed rises, the combustion process speeds up in parallel.
By contrast, in diesels, the non-homogenous charge means the combustion proecess is completely different. and does not speed up with engine speed. At higher rpms the power stroke would be too short (in terms of time, in seconds/milliseconds) for combustion to complete. Hence there is a low engine speed limit.
Atomisation of the fuel can be achieved through extremely high injection pressures, currently over 2000 bar and ever-climbing. Modern diesel injectors are quite incredible pieces of kit, in terms of both high pressures and control. But no-matter how well you atomise the fuel, there are issues with the stratified-charge compression ignition process that limit engine speed (and more importantly, lead to high NOx and PM emissions).
HCCI is probably a no-go, in terms of complexity. But higher injection pressures, modified fuel injector geometry and maybe some form of premixed combustion (PCCI) may be feasible.
Also, the idea that diesels are low-powered in something of a misnomer. Everyones looks only at displacement and power output, as if one 2,0l engine is directly comparable with another. These are really just design choices in the hands of the engineer.
And the crazy thing is, OEMs are actually looking at reducing specific power in diesels again, and reversing the downsizing trend. Moving back to bigger engines with lower specific power, lower combustion temps and lower NOx emissions.

Greetings to Saudi Arabia.
>>14844416
Great post. Your last point was quite interesting: are there examples of companies changing engines in the way you are describing?
>And the crazy thing is, OEMs are actually looking at reducing specific power in diesels again, and reversing the downsizing trend. Moving back to bigger engines with lower specific power, lower combustion temps and lower NOx emissions.
>>14844416
propane injection m8, its how you overcome the shitty combustion.

Sounds like Commer TS3.
6 piston horizontally opposed 3 cylinder supercharged two stroke diesel.
Barks like a mad cunt.

I just hope to god the world goes with peanut diesel instead of electric cars in the future, i cannot imagine living in a shit world where cars are electric. I just wanna brapbrapbrap
>>14844407
diesels are far more energy efficient than gas this is a widely known fact, educate yourself
>>14844583
>brapbrapbrap.mp3
Sorry but electric is the way of the future.
Your electric car will play engine sounds if you want it to.
>>14844591
Thats like saying titanium is stronger than steel.
>>14839418
>mfw that loud as fuck, busted ass truck sitting in the back yard has the highest power by engine type
you cant be fucking kidding me?
that motherfucker is slow as balls, mated to the worst god damn automatic 3 speed automatic transmission and struggles to hit 55mph.
>>14844596
well it is in most regards
>>14838675
>No Indenor diesels

Why even bother listing diesels in the first place?
>>14844530

electric cars are the vapes of the car world, if government makes it mandatory to only drive electric i will suicide
>no turbo
k, twin turbo then
Just listen to this:

Cheers brah.
I never studied mechanical, only material.. even though I was accepted into mechanical
>>14844602
Titanium is stronger/tougher than steel at the same weight, and since titanium is much lighter than steel it means a 1/4" piece of steel is still stronger than a 1/4" piece of titanium.
For petrols and diesels kind of the same thing.
Diesels put out more torks at lower revs, meaning less fuel consumption needed to move whatever needs to be moved.
So economy is a factor, but the biggest reason why industrial machinery is always Diesel, is because Diesels last thousands more hours.
Although I still think there's no replacement for good ol' displacement.
My next engine will be an LS3.
Put it on LPG. Sorted

They are pretty quiet unless people mod them.

>>14844726
Right, kinda ignored that for some reason.
>>14844744
Basically.
High strength steel will be much "tougher" than titanium and a lot cheaper too.
Titanium is basically just high strength for light weight. But it's so expensive even aircraft manufacturers wouldn't use it. Hell, the new Boeing uses mostly composite materials for the fuselage. Aluminium is mostly too heavy for even that now
>>14844754
By tougher I mean it may be in all shapes and sizes but it won't have failed
>>14838675
You are literally spreading cancer you filthy little shit
>>14844438
To be honest, not much that is available right now. The only real example is Audi's new EA888 TFSi. But it’s petrol.
http://www.greencarcongress.com/2015/05/20150514-gen3b.html
This paper by BMW talks about the potential of “rightsizing” for diesels: http://link.springer.com/chapter/10.1007%2F978-3-658-08844-6_95 . I couldn’t find a publically available source though.
Basically, it’s driven by the move away from the NEDC emissions test cycle, to a higher-load cycle (WLTC) and real-world emissions testing. For higher loads, the "optimum” engine architecture to pass the emissions test is moved towards larger displacement.
>>14844737
No problem, man. I'm no metallurgist.
>>14838675
>OM602
You fucked up.
>>14839849
I would actually buy a charger just because of that.
>>14844744
It's not just the torques, you could make a gas engine with as many torques as you want.
Compression ignition is just inherently more energy efficient.
>>14838726
why would anyone insulate their engine with paint?
>>14845728
My guess is its marinized, so probably to protect it from salt water corrosion.
>>14844754
Hahaha the plane I work on has the APU encased in a titanium box something like 2.5' x 3' x 4' and many, many screws made out of shit, got the broken drill bits to prove it
