Black Smoke.....power or waste?

Not true, you only need a good ECM tuner these days, one who knows what is smoke limiter map.

But smoke will always make a little bit more power but very inefficiently.

 

stroke is same for both engines (156mm)

bore is 127mm on old engines (up to 620) (15.62L)

now it is 130mm on new 16.35L v8

but new one have vgt have xpi common rail ......


as for fuel consumption

r480 e5 egr and r500 v8 have same fuel economy but r500 need also Ad blue (DEF)

 

The 850HP Cummins I drove in 97 built from a 444 you would not have known it was a High horse Monster by looking at her exhaust. Why she did it without blowing the Black Smoke. The When your pumping the right amount of Fuel in and the right amount of air you can make unlimited HP without Smoke.

 

Right amount of fuel in the right time to the right amount of air.

 

Yes, it's the EGR.

Stroke and dwell time has nothing to do with smoke. Higher rpm engines at same power and displacement make same power with less fuel per stroke, they don't need as much time to burn that fuel amount. Comparing old Cat, Cummins and DD V engines to todays inline engines is useless, they are a whole different and outdated engines.

If you want to look at real hightech diesels today you must look at European Truck Racing Championship engines or some Le Mans diesels, they have some very interesting parameters. For example a Renault DXI 13 (Volvo D13) has as low as 15:1 air fuel ratio but there's no smoke coming out of the exhaust. They make about 1150 hp with only 0.8 kg/s of air. That is easy to make with a normal production turbo like HX60, GT 42 or S400. Their torque is also something like +5000 Nm from 1200 rpm upwards.

 

In reality the e4 480 is a hell of a lot slower than the e3 500 and not as good with fuel, I had both to compare them, Ive seen a few e5 480's and they look hopeless on hills too! Sent both trucks together to Barcelona pulling box vans with 2 loads of computers, 29 tonnes gross, 480= 9.9mpg, 500=11.1 mpg.

 

I believe that! Trucks I've seen here with massive hp don't belch out massive amounts of smoke either, you would be facing a fine if they were belching out the kinda smoke like in the videos here.

I bet that was a joy to drive?

 

I'm really put off all the new inline engines, the r480 isn't a great truck, it's good but not great def not as good as older 470, I drove a new magnum with a Volvo engine, that really was ####e, older volvo 12/13 litre engines were fine, never overpowered by any standard but they have gone downhill! The v8 is the only decent engine left this side of the pond anyway,

 

She was and she is still around a local Farmer bought her and hauls Grain with her today. I am friends with the owner of her and he called me during harvest and asked if I wanted to ride with him for a day in her. I was like SURE. She still has the power that she did 14 years ago and he is going to O/H her this winter to freshen her up. Well with 2.4 Millon on her and 1.3 since the last one it is time for another rebuild. Also she was leaking oil from the #2 head gasket and his last Oil sample showed alot of fuel Contamination in it. So time to Freshen her up.

Here was how hard that truck could and did pull coming out of Philly PA heading for home with a load of Honey drums in the wagon. Got back to I-80 and hit Snowshoe coming Westbound. Now Snowshoe in PA west is a harder pull 6% for a few Miles well there was a guy with a big Kitty ahead of me by 1/2 mile I spilt down and stood on her. By the top of the mountain I was 1/2 mile ahead of him. I only dropped down one more spilt I was in 11th at the base ended up in 10th at the top of the hill. I ended up going west alot with that truck.

 

Scania 5,6 and 8 cylinders share the same parts so they should be as good if the emissions system were the same. I planning to buy a Euro 5 D13 Scania and program all the emissions ####e off, I believe it will be a great engine, Commonrail system is quite sensitive though but soon all V8 will have that same system also.

Don't know if there's any real good engines these days, it's not only emissions but also profits for shareholders, they try to build engines as cheaply as possible so that they barely do warranty period without problems, after that they don't care. BTW, I heard that one finnish company with 30 something Euro 5 13 litre Scanias got 800 thousand kilometer warranty for engines because they had so many problems with them. That same company bought MANs a couple of years ago and send them back after about a year and changed to Scania because those MANs were total crap.
