Can you please rephrase your question and post again.
Detroit DD15 has better horsepower and torque than any other EPA2010 engines. So far on Detroits, they have better reliability than Maxxforce engines. I tried the 2012 Freightliner Cascadia with Detroit DD15 and its goes like C-15. Big question is, which EPA2010 engine is the best?
You have an option of Detroit Diesel DD13 or DD15, or the Cummins ISX12 or ISX15.
Mine weighs 20,900 lbs. Both tanks completely filled with fuel. Equipped with 14.8 l DD15 engine. Model year is 2009 (Equipped with DPF tech no SCR) This weight includes my weight abt 180 lbs along with chains and other gear, tools etc. There is no modification to the truck ie no APU installed, No Tire Carrier installed.
From 2003 onwards, only Freightliner, Western Star, and Sterling trucks (or vehicles built on those chassis). I believe the DD15 is available in some Mercedes-Benz trucks outside of the North American market, as well. Before ACERT, they could be had in Volvo (North American models), Peterbilt, Kenworth, and International trucks, as well. They have also been available in the past to other truck manufacturers which have since gone defunct.. Ford (the heavy truck division was sold off in 1997), Chevrolet/GMC (they used to have a heavy truck division), White, Marmon, etc.
For a regular, line haul tractor such as the Coronado, Coronado SD, or Cascadia, you'll have the options of the Detroit Diesel DD13 or DD15, or the Cummins ISX12 or ISX15. For smaller models, such as the FL112, which are typically used for vocational trucks or local P&D trucks, the Detroit Diesel 50 Series or Cummins ISM or ISL9 can be had.The Mercedes-Benz MBE4000 12.8 liter was an available option for Freightliner, Western Star, and Sterling trucks (all three of which were Daimler A.G. subsidiaries; Sterling trucks went out of production in 2009). This engine replaced the pre-02 emissions Detroit Diesel 12.7 liter 60 Series.Caterpillar engines were available until Cat left the highway diesel market in 2009, following the disastrous debut of the SDP engines. Their repute was already suffering on account of the ACERT engines, and the SDP was the final nail in that coffin.
peterbilt or kenworth are both higher quality tractors. freightliner is also a good tractor but its quality lacks in areas. with that being said all tractor manufactures build good ones and bad ones. they are all junk when you have to work on them freightliner According to my driving instructor, Volvo is currently the most technologically advanced tractor on the market. Volvo used to have a problem in that Volvo trucks contain Volvo engines, and technicians were hard to find. These days, there are so many Volvos on the road you can find Volvo-certified technicians all over the place. Peterbilt and Kenworth are both made by PACCAR. They're both excellent trucks. The two most popular brands of truck are International and Freightliner.
3 - 7 MPG. Fuel mileage is determined by a number of things.. the engine, for one. The speed the vehicle is operating at, the gear ratio and RPMs being turned at those speeds, the stochiometric ration (fuel/air mixture), driver habits, etc.
There are three reasons to buy a Cummins ISX over a Detroit DD15: if you need 600 horsepower and you can't bring yourself to buy a DD16, if you like running the engine at 1500rpm like we all learned to do in CDL school, or if you don't like Freightliners. The main reason to buy a DD15 is it's more fuel efficient than an ISX--if you can keep the RPM down. It wants to run somewhere around 1250-1300rpm, and loses a lot of power at 1500. So...when you buy the truck, you tell the sales rep what you're hauling and on what kind of terrain you're running on, and let the dealer help you get the transmission and rear end gears you need. If I was going to buy a truck right now, which I'm not--they're really expensive and I haven't won the lottery yet--I would get a Freightliner Cascadia with 600-hp Detroit DD16, moose-guard bumper, 18-speed autoshift, super single drive tires and 3.55 rear end. 18-speed will save you a lot of fuel if you know exactly how to shift it but will clean your bank account out if you don't; the autoshift system solves that problem. 600hp is for hauling heavy loads up big hills; if you're sitting on the side of a mountain in Pennsylvania or Idaho with a load of beer in the back, the only thing that's going to get you up efficiently is a huge amount of horsepower. Super singles are better for fuel mileage, and the Cascadia has a very nice sleeper. Adding to the above, the Cummins ISX motors have gotten a lot better since the first generation of them came about. However, I'm still of the opinion that the pre-ACERT N14 motors were much better (and I feel the same way about the old 12.7 litre 60 Series Detroits over the 12.8 litre MBE4000 and DD13, as well as the 14.0 60 Series - but you kinda get into the apples vs. oranges debate comparing the 12.7 to the current DD15). If I were to buy a truck right now (and, as above, I'm not intending to), it would probably be a Kenworth T800 with a wet line, 50k rears, a 23k front, and a double frame. For that application, your only current options are the ISX15 or the 12.8 litre PACCAR MX motor. The ISX has a wider powerband than the DD15, which would be beneficial for the applications I'd use it for. I'd run an 18 torque 18 speed Eaton Fuller (while it can be a bit excessive for a typical road tractor, the real value of the 18 speed is in off-road and heavy haul applications), and either 4.11s with an overdrive transmission, or 4.33s with an 18 double over. It's a niche which the (no longer available) Caterpillar and Cummins motors are much better suited for than the Detroit. One thing you have to keep in mind, as well, is that, the higher displacement the motor, the higher the tare weight of your vehicle. Sure, it's nice to have a DD16 Detroit, C16 Cat, or D16 Volvo (at least, so long as someone else pays the maintenance bills for the Volvo), but they're much heavier in comparison to the motors in the 13 litre range. By the way, horsepower is less important than what it's made out to be. The Cummins 6.7 found in current Dodge pickups can crank out over 500 horsepower, but it's in no way comparable to, say, an ISX motor cranking out 500 horsepower. The displacement, powerbands, and torque ratings are much more relevant here.
There are a few options. Since "big rig" is an American term, I'll assume you're talking about American trucks. For a typical tractor-trailer unit with a total of five axles, the engine displacement can range from 10 to 16 liters. 10, 11, and 12 liter engines will be more common for local trucks, doing things such as P&D, LTL, etc. Line haul, long distance trucks most commonly have a 13 to 15 liter engine. The only manufacturer currently offering a 16 liter is Volvo. The current (as of 8/2015) truck manufacturers in the US are PACCAR, Inc. (Kenworth and Peterbilt), Volvo A.B. (Volvo and Mack), Daimler A.G. (Freightliner and Western Star), and Navistar (International, and a cooperative effort with Caterpillar, Inc.). Ford got out of that Class 8 truck business in 1997, when they sold their heavy duty truck line to Daimler A.G. (who put the trucks into production under the Sterling name ontil 2009). General Motors got out of it in 1988, when they sold out to Volvo A.B. Marmon closed their doors in 1997.Engines currently available for these trucks include the 11 liter Cummins ISM and 12 and 15 liter Cummins ISX (available in all makes of truck), 13 liter VE-D13 (available in Volvos and in Macks as the MP-8), 16 liter VE-D16 (available in Volvos and in Macks as the MP-10), 13 liter Maxxforce 13 (available in Internationals and an engine based on this one is used in Caterpillar trucks), 13 liter Detroit DD13 (available in Freightliners and Western Stars), 15 liter DD15 (available in Freightliners and Western Stars), and 13 liter PACCAR MX13 (available in Kenworths and Peterbilts). Caterpillar got out of highway diesel after 2009, after the fiasco with their SDP engines. Detroit Diesel engines became exclusive to Daimler A.G. products (Freightliner, Western Star, and, until 2009, Sterling) after 2002 (they had previously been available in most makes of truck prior). Mercedes-Benz engines were available in Daimler A.G. products from 2003 - 2009.
Well...it depends on the engine: * Detroit Diesel DD15: 47 quarts, or 11.75 gallons * Detroit Diesel Series 60: 39 quarts * Cummins ISX: 54 quarts * Caterpillar C15: 40 quarts * Mercedes-Benz MBE 4000: 44 quarts I can't find the capacity of a Volvo D15, but it's right up there. You don't change the oil in these trucks every 3000 miles. If you did you'd be changing it every week--a solo driver can easily do 3000 to 3500 miles a week, and guys pulling teams can do 5000 miles easy if the freight comes down right. A fleet that does regular oil analysis can easily get three to four months' service out of an oil change.
Burning techniques are totally different when comparing Diesel and Gasoline. In Gasoline engines, air and fuel mixture is injected into the cylinder (in a non direct fuel injection system) this mixture is then compressed and thus temperature of the mixture increases, but not to the ignition temperature, this is why we need a spark plug in gasoline engines to start this small fire. After reaching the top dead level of the cylinder (or sometimes even before that ) spark plug releases its charge and start a very small explosion inside the cylinder head. This small fire ball propagates as far as there is enough fuel and oxygen. While this explosion propagates, the piston is being pushed down and turning the flywheel through the crankshaft. As you can see, you don't need to compress this air and fuel mixture till ignition temperature and you don't want to do it!!! This is why it is possible to design gasoline engines with short strokes. Short strokes means short reciprocating movements, which means faster rotational speed. In diesel engines, there is no spark plug, because ( and I'm not 100% sure about that ) Diesel is not a good fuel in propagating a controlled fireball. It just doesn't work very well in diesel. Because of that, Only air is being compressed inside a diesel engine during the compression cycle. Somewhere during compression stage, diesel is being injected inside the cylinder and starts to spread homogenously inside the cylinder, compression continues and the mixture is mixed and heated up till it reaches ignition temperature. Once ignition temperature is reached, the whole mixture explodes at the same moment. As you can see, there is no flame propagation in diesel engines, the whole mixture just explodes in a single moment. And in order to reach ignition temperature you need a long enough stroke to be able to compress air till it reaches ignition temperature of the fuel. Longer stroke means slower cycle, but higher torque. This is why Diesel engines have more torque but less speed than their gasoline counterparts. Hope this answers your question. - - - - - Okay... The Diesel engine (named after Rudolf Diesel, who invented it) was designed to burn any flammable liquid you put in it--Herr Diesel originally intended to run it on vegetable oil. OTOH, a spark ignition engine requires fuel with a minimum amount of volatility, so gasoline has to be a very highly refined product. The Diesel cycle compresses air inside the cylinder until it's hot enough to ignite the fuel. At that point, the injection system squirts a premeasured dose of fuel into a combustion chamber in the cylinder head. It ignites instantly. Because the flame front is confined to the little chamber the fuel's being injected into, there has to be a LOT of excess air in there. To get it, the engine is "oversquare"--the stroke is longer than the bore. (A Detroit Diesel DD15 is 5.47" bore, 6.43" stroke. It's an inline 6 engine that displaces 14.7 liters. Now here's where it gets fun: The DD15 comes in eight different horsepower ratings, and the only difference between the eight engines is the fuel injector system--the more power your engine has, the more fuel the injector holds. (There's also a different program in the computer, but that's another issue.) Before the EPA got all antsy about diesel emissions you could take your truck to Pittsburgh Power, have them install higher-flow injectors and have a much more powerful truck for relatively little money. (You can't do that now; the current electronic fuel injection systems on big rigs keep you from doing that.)
