By bmcfarorAugust 15, in Engines. You will save money by buying a coach that does not require DEF. Coaches built before this requirement will not have any ongoing issues that should prevent you from buying one. Kind of like when gasoline engines went to catalytic converters. If someone knows of a statistical evaluation or reliability rather than an opinion-based one, would like to see it. The poster mentioned that he has a 04 or 05 model year at the time and should have first hand experience with the VGT Turbos.
Regarding the DEF system on Diesel engines. The only information I have reference to and no direct records. They do not like long idle times, stop and go causes issues with the system.
They have more problems with the system in cold weather keeping the system hot enough to not set check engine and loose of power. The solution has been to keep them running at a high idle and running in a lower gear to keep the exhaust system temperatures up.
This temperature issue has also shown up with failed EGR valves failing due to soot build up in the valves. The engine builders get more real time and world information over the years and things should get resolved,but does one want to be one of there guinea pigs.
So if it is a Cummins engine it should only have a particular filter on the exhaust and not require DEF additive. I have had no problems with performance. The exhaust tailpipe does not have the black soot on the inside as I have found on my previous units which I attribute to the particular filter. The MPG is the best I have ever had on a motorhome and the pulling power is outstanding.
I would also added that a major consideration in your decision process should be what I refer to as a weight to power ratio. If you you have a heavy coach and marginal engine HP you may not have an enjoyable driving experience. Engines are rated at sea level. I think you will find that many diesels are rated at full HP up to 10,' due to their turbo "making air".
This is true for non turbo engines. Virtually all diesels are turbo, so they are not bothered by altitude The engine doesn't know if it in Key West or climbing the Rockies. Be aware that coach manufacturers purchase engines in quantity and then install them in coaches until they run out of that stock.
Your coach may have an engine manufactured in or even Don't assume that the year of manufacture of the coach matches the year of manufacture for the engine. Tom is correct-- chassis builders bought ahead each time there was an EPA tighter standard as engine price also went up. And EPA standards follow the engine.Kirkland flushable wipes ingredients
If you have any questions as to it's engine build date, call the engine manufacturer with the engine serial number. There was a story out several years ago about Cat Engines.
It seem that they had on static display one of the first engines manufactured by Caterpillar.A motorhome is a large, self-propelled recreational vehicle RV. They can look like small apartments or tiny homes, have all the luxuries you'd want, and can eclipse even the biggest 5th wheel RVs and diesel pushers RV with a rear-mounted diesel engine out there when it comes to square feet alone. Each class has its own pros and cons.
This is a break down of the motorhome classes, so you can determine which type of motorhome is right for your travels. Class A motorhomes are one of the biggest RVs on the market, eclipsed only by "toterhomes" a motorhome with the ability to tow or carry a vehicle, boat, trailer, etc. When you think of RVs, you imagine this type of recreational vehicle. Class A motorhomes offer the largest square footage you'll find in an RV.
They offer all the features you'd find in a small apartment, along with custom options that can be added in during the initial build or down the line. Class A motorhomes aren't for everyone. The size can be an issue for a driver who's not used to handling something so gigantic on the road, and you often must find RV parks and campgrounds that can handle a much larger rig. Class B motorhomes are the smallest motorhome type. They are also known as van campers and look like an oversized family van on the road.
Class B's are easy to park, use less fuel than Class A motorhomes, and make boondocking parking for free and dry camping easier for adventurers looking to travel off the beaten path. This is a blessing and a curse. Since Class B's are smaller, they are cheaper and easier to start with, especially when it comes to gas mileage and parking. If you have a larger family or friends who want to travel with you, a Class B isn't going to get the job done when it comes to comfortable space to travel in.
Twin beds and sofa beds are common in these motorhomes. They look like a larger version of the van camper with an overhead cabin above the driver and passenger seats for extra sleeping or storage accommodations.
Class C motorhomes give you more space than Class B motorhomes and come with all the luxuries you'd expect in a Class A motorhome.Abbotsford shelties
These types of motorhomes are perfect for couples or a group of friends looking to hit the road.Cummins ISC 8. It is also the year that Cummins began manufacturing their ever versatile ISC 8. Based on the earlier mechanical 8.
Perfect for vehicles such as fire trucks, garbage trucks, as well as generators and heavy-duty equipment. It is hailed most loudly in the motorhome market where it is regarded as legendary. Also known as the "C- Series", Cummins set out to design an engine which would get every ounce of performance and reliability of the engine.
The Holset Engineering Company is a British business that manufactured turbocharges predominantly for diesel and heavy-duty applications and Cummins purchased the company inturning it into a worldwide brand. Though Cummins changed the company name to Cummins Turbo Technologies inthey kept Holset as a brand name as it is synonymous with turbochargers throughout the world.
The VG turbo makes it possible to use exhaust braking without the need for any extra hardware while at the same time eliminates exhaust break maintenance. The High-Pressure Common Rail System is a highly efficient fuel injection system that is essential for the clean operation of a diesel engine. It also improves the regulation of fuel pressure and injection timing. It works by the pump applying high pressure to the fuel which is stored in the Common Railthen injected into the engine.
They integrated their advanced electronic controls, improved their high-pressure fuel system, upped the performance of their combustion technology and with ecology concerns growing, gave the engine the capability of greater exhaust after treatment. The DOC works by oxidizing the carbon monoxide, gas phase hydrocarbons, and particulate matter to carbon dioxide and water, therefore removing the majority of the polluting elements given off by diesel.
The SCR converts the nitro oxide into nitrogen and water. The DPF removes the soot or particulate matter from the gas of the exhaust. It does this by adjusting the fuel injection which increases the exhaust temperature causing the soot to burn off, while simultaneously regenerating the filter.
Today, the ISC comes with the Cummins Other features include sensors that alert the driver of any fuel contamination such as water, that left undetected, could lead to problems with performance and durability.
The big engineering feat of the Cummins ISC 8. The frequency of oil changes was examined and then designed to dramatically reduce them to, on average, once every 15, miles.
Maintenance of an engine is key to its durability and reliability and Cummins have ensured that this essential task is not left to chance with their Maintenance Monitor. When set up it will advise the driver as to when maintenance tasks need to be carried out, such as oil drains, filter changes etc. During set up, you need to tell the Monitor essential information like oil grade, type of Turbocharger and Sulfur Content of the fuel. When carrying out maintenance work Cummins strongly recommend using only products that meet their standards of quality.
The engine is also equipped with an Electronic Diagnostic system. Unlike the smaller 5.

It then analyses the data to identify any possible causes of engine failure. Once found the driver is alerted by the way of a warning light. If a Road Relay, which is an onboard monitoring system that provides the driver with trip information such as miles per gallon and engine fault details, is used in tandem, the alert will be given via the visual display in the cab.
If the problem identified is severe the engine may limit speed or reduce power output in order to minimize any potential damage. The diagnostic system also acts as a powerful troubleshooting tool, logging fault codes and other key pieces of data each time a failure event occurs.
Using this information, problems are quickly spotted, and repairs can be completed in much less time and with greater efficiency.Experiment 25 report sheet calorimetry part b
The computer controlled Cummins ISC 8. The Cummins ISC engine is also protected by the engine protector systems which monitors critical engine parameters to safeguard against progressive damage. As well as automatically taking action to reduce any potential damage it can also be set to carry out an engine shut down.
Unable to be overridden the engine is constantly monitored and protected.Cummins ISB 6. The ISB 6. Its predecessor, the ISB 5. It was outdated at that moment and depleted the limits of possibilities for improvements in terms of fuel consumption and emissions.
The market needed a new engine for medium-duty trucks and buses and the ISB 6. The 6. That allowed to increase its displacement to 6.
The engine block is still made from cast iron. On top of the block, there is a valve cast iron cylinder head similar to the ISB 5. The difference between ISB 5. There are many changes over the previous 5. The new version was designed guided by stricter requirements on Federal emissions regulations.
When it was released inthe engine was the first Cummins diesel which was equipped with a diesel particulate filter DPF. The DPF filter cleans the exhaust gases from soot by more than 90 percent. A diesel particulate filter has a ceramic matrix, which filters soot particles and regenerates them under high temperature, heated by exhaust gases.
Also, the engine had the exhaust gas recirculation system EGR with cooling. So 2 liters of DEF is consumed for every liters of diesel fuel. This turbocharger can block exhaust flow to increase temperatures inside the DPF, which reduces emission levels.
The VGT also has the integrated exhaust brake function. It does the engine braking by restricting exhaust flow. All ISB6. The improvement process has never been stopped during the last ten years of production, so the model year engines are able to produce up to lb-ft of torque.Changing The Air Filter/ RV Diesel Pushers (Freightliner Chassis)
The ISB6. In stock form, the failure rates are meager. The common problems are related to emissions equipment and common rail injection.Necessary cookies are absolutely essential for the website to function properly.

Diesel is awesome but what diesel truck engine out there is truly the BEST? Cummins guys will fight until their dying breath that the Cummins 5. The debate is as old as Rudolf Diesel himself. Good thing someone else is willing to take the bullet for me. The guys over at Capital Remanhave given it their best shot to rank the Top 10 Best and Worst diesel engines of all time.
This article is about what they came up with. Did they hit the nail on the head or completely miss the target on this one? You need to tow something these engines have got you covered.Western saddles
It is a favorite of fleet managers because they run forever, have great torque to power ratio and can actually be rebuilt right in the frame of the truck. Number 5 seems fitting for the best diesel engine for the sheer number of units currently still on the road. Ford adopted the Powerstroke officially in but was unofficially in production starting in The predecessors were bigger 6 cylinders however an International bean counter decided it would be a grand idea to chop off 2 of the cylinders producing a 4 cylinder engine.
Best diesel engine? I think not. Why We Like It: Ruff! Mack has always been known as a slow and steady workhorse.
Cummins ISB 6.7L Engine Review
It produced its first hook and ladder fire engine inproduced over 6, trucks for the US and British Military during WWI and helped build the Hoover Dam in These are the engines that built America.
The Mack E-7 was first produced in and lasted until the early 21st century.Sfiato serbatoio benzina
They are extremely simple to overhaul and rebuild and do exactly what you need for them. Good on ya Mack! That and there only like 5 models.
It is amazing how many people bleed yellow and rightfully so in most cases. There have been some catastrophic failures in the Caterpillar line of engines; the E is not one of them. This was a very successful engine for CAT as it was really the first evolved electronic engine that was done right. This was such a great engine that the vast majority of Peterbuilt trucks in the mid 90s and 00s all had Caterpillar E engines in them.
The ECM design was easy to work with and bread a following of programmers that were able to write a variety of software for the engine. Even in the CAT E is still in millions of on-road and off-road applications across the world. Overall Caterpillar is the unofficial king of diesel engines and it deserves its place as number 3 on the best diesel engine list. It is extremely hard to time the fuel system and like the VW on the automotive side, working on the CAT requires special tooling you can only buy from Caterpillar.
The CAT was engineered to be disposable.FCCC offers a variety of choices from the top name in diesel-engine design. With horsepower ratings from to hp, these engines will deliver the performance you expect when you need it most and provide a lifetime of no-hassle maintenance. And all of the latest engines are proven to meet emissions standards required for the legislation. They also provide:. To review specs and information on particular Cummins engines, visit their website.
Rear-engine diesels provide a host of benefits, including more floor plan options, quieter interior environments, more comfortable rides, lower fuel costs and effortless hill climbing. You'll also appreciate the enhanced reliability of a diesel engine and the fewer maintenance stops. Side-mounted radiators are available on our raised-rail designs with Cummins ISL engines. Like our rear-mounted radiators, this design features a variable-speed fan that automatically increases and decreases fan speed as needed to reduce noise and decrease power loss.
Conveniently positioned near the diesel tank for quicker fill-ups, the DEF tank also features stamped brackets rather than formed sheet metal.
