Why do so many Americans hate European trucks?

Generally it isn't that particular. That is a very unique individual. On this side of the pond it takes about 6 months to get a new boat transport trailer delivered. No need to hire your own personal engineer.

 

you can use standard low bed trailers to pull boats but with limitations.

you can get here boat trailers from stock in italy they might satisfy some users and price is pretty affordable.
if you want something extra you have to find company that can build to your wishes., once you go to very specialized company this is going to cost you much more for same thing at other manufacturer....every extra wish will cost you some serious money. once you cross line of what they have developed and want something nobody asked for...and have few of such wishes that is going to cost you more than trailer itself.

he have rent engineer to take inspection of every detail on truck, he would make all conversions, body and equipment installation by himself as usually. but crane manufacturer did not allow that, it have to be certified dealer. as for trailer. it is very low trailer can take load at 5inch from road, with clearance of 4inch. use suspension with very long travel (more than 2feet) custom made in italy. frame of trailer is placed outside and it is actually very compact dimensions. there are 2 movable platforms, to better adjust load. it is telescope trailer of course, it can take load very deep low in between tires as it use low beam axles which are not made in regular product range. load itself is supported by hydraulic arms one pair of arms is softer to allow slight movement to prevent damage when trailer from trailer torsion. he have air supports for part of load to prevent damage from bottom. front of trailer can be raised additionally to get some more clearance forward, he use sliding and removable crossbeams in frame to allow more flexibility and lot more. also it can load trucks and tractors if needed.
you need to consider that same boat can be transported way easier in usa due different road infrastructure. i have seen trailer and other mb 3 months ago, trailer is about 50% made.

also in soon future he wants to buy lowest tractor and get more or less standard 3axle boat trailer for long distance. that trailer can be made by normal manufacturers so no need to make it by himself. mb got lowest tractors on market

 

Here moving boats is a relatively common segment of the trucking industry. Ordering a boat trailer is only a little more involved than any other 'specialised' trailer. Nothing really special about them, just built specifically to haul boats. No more special than say a livestock or car huler. Just build it as low as possible, which is rather easy considering the low weight of boats. They go down the road every day here especially in my area. The east coast has a ton of mini yachts getting shipped from Florida to the northeast and back. Same with the West coast and all along the gulf of Mexico and the great lakes. The real yachts are never shipped by land, but that's because of size limitations. You can't take a 30 ft wide 100 ft long, 50 foot tall yacht on a road.

 

Air consists out of 80% nitrogen and 20% oxygen. Diesel engines normally work with an excess of oxygen, because contrary to gasoline engines, there is no restriction in the amount of air they can suck in. However when the diesel engine reaches its maximum power, almost all oxygen will be used. Injecting more diesel fuel will result in partial burning of the fuel, resulting in those beautiful smoke plumes you all like so much.

Now let's say I replace 1 litre of fresh air by 1 litre of exhaust gas (EGR). 80% of that litre of fresh air consists out of nitrogen. Since no nitrogen is added or removed, 80% of 1 litre of exhaust gas also consist out of nitrogen. In other words, no nitrogen is added to bring down the combustion temperature., there's exactly the same amount of nitrogen in fresh air as in exhaust gas. Replacing the same amount of fresh air by exhaust gas will not change the amount of nitrogen.

With oxygen it's very different. Let's say all oxygen has been burned, then the 20% oxygen in the fresh air has been replaced by 20% carbon-dioxyde, which is an intert gas. So the EGR process replaces oxygen by carbon-dioxyde, and the nitrogen in the fresh air is replaced by the same amount of nitrogen from the exhaust gas.

 

No, at maximum power there will still be plenty of oxygen, on a standard (not-tuned) diesel engine. The Air/fuel ratio is at it's lowest (richest) near maximum torque, where the engine does not produce the high boost, and fuel injection is at it's maximum.

In the image below you can see that this engine still has 10% oxygen in the exhaust gases at max. power. Only about 50% of the oxygen was used.
At maximum torque the exhaust gases still have 7% oxygen.



The beautiful plumes of black smoke start appearing at about 3% (or less) oxygen, and are in most cases the result of too low boost pressure for the amount of fuel. Fuel is injected, but turbo needs time to spool and deliver the boost and air.

In modern engine, the ECU will limit the fuel based on boost pressure to prevent this.

On older engines with mechanical fuel pump, the Air/Fuel control will do the same thing but mechanically. Boost pressure acting on the A/F diaphragm and allowing more or less rack travel.

As explained before, all oxygen has not been burned. There is still oxygen in the exhaust gasses.

The nitrogen in the fresh air being replaced by the same amount of nitrogen in the exhaust gases is not correct either.
The same volume of exhaust gas has less nitrogen than same volume of air, because the exhaust gases also contain water vapour and CO2.
The total volume of exhaust gas will be larger than the total volume of air going into the engine.

Another thing you don't take into account is the fact that the engine will also be running higher boost pressures in EGR mode than when the engine is running in non-EGR mode.

Based on these facts, you can not simply say that the amount of nitrogen is the same, with or without EGR. It is not that simple.

 

Fine, but in any way, it is not the nitrogen in the exhaust gasses that is doing the cooling down trick. It is the CO2 and the H2O that are replacing oxygen.

 

euro is stuck with there trucks cuz they got #### roads all over the eu.

 

Don't think you did to well in chemistry. It is all chemical reactions. Oxygen is not replaced, a chemical reaction occurs.

 

I'm done with this thread. I guess factory training and real world experience doesn't count for ####.

 

But google says......
