This new design reduced a large open space between the ring and the piston liner. By utilizing this space the combustion chamber moved closer to the top ring which meant the oil got much hotter and burned off more completely. For all of the great aspects of the Cummins N14 its Achilles Heel has always been the injectors.
The L10, M11 and N14 all have problems with injector failures and the surrounding electronics. Usually this starts out with only 1 injector shown to be malfunctioning but can quickly spread to others.
If this happens you immediately want to shut down the engine. These early electronic engines offered no protection against the wiring harness shortening out. There are 6 injector driver connections on the ECM which are attached to the injectors via a wiring harness. If an injector goes bad it is advised to pull out the wiring from the injector and replace immediately before the faulty wire burns up the ECM motherboard.
The wiring harnesses are known to have problems and are very expensive to replace. Another issue with the N14 ECM is a faulty fuel solenoid. The solenoid is situated on the bottom of the ECM. If the solenoid shorts it will heat up the ECM slowly and can then destroy the entire fuel solenoid circuit, memory chip and the injector timing chip. Usually the solenoid gets so hot it melts the solder on the chips. For a 50 pin connection all it takes is one pin to loosen from the heat to destroy the ECM.
It is recommended that drivers carry extra injectors in the truck in case one goes out. Usually they go out in pairs which makes sense to carry 2 at all times. ATF additives prevent oil loss, helps protect and regenerate seals and rings, cleans out oil sludge, improves steering performance and helps protect the engine during shifting. Most operators will put in 1 quart of ATF per gallons of fuel.
Other preventative measures with the N include using an alcohol based additive to kill off algae from newer blends of fuel. The algae in these various blends tends to eat through the older OEM fuel lines. Kind of rolls off the tongue eh?! The Cummins Big Cam was the last real mechanical variable timing engine mass produced by Cummins in the The Big Cam replaced the small cam and was the first engine by Cummins to meet the Clean Air Act and noise regulations of that time. There were four generations of the Cummins Big Cam engines, last produced in and was replaced by the N We love the Big Cam because of the raw horsepower it puts out as well as its reliability.
You can easily run a Cummins Big Cam , miles before an overhaul. The Cummins Big Cam was the first engine by Cummins to utilize demand-flow cooling which only cools the engine when the engine demands it. This system then uses the saved horsepower at the crankshaft for more horsepower into the project at hand.
The Big Cam II significantly upgraded performance by introducing pulse manifolds into the engines; these were a big selling feature in these engines at the time.
Overall horsepower was the main reason this engine was a big seller over the small cam models. The Cummins Big Cam had one of the largest camshaft diameters on the market at the time and features top-stop injectors. Talk to any old school truck drivers in the s and they will tell you tales when the Cummins series were the king of the road.
Hard not to leave these engines off the best diesel engine of all time list. There were some drawbacks with the specifically when trying to start the engine in colder climates.
That being said a glow plug or a shot of ether should do the trick to fix this simple issue because overall this is a great engine. It was supposed to be the Caddalic and the best diesel engine every designed at Cummins. However that didn't pan out exactly. The ISX was engineered with a dual overhead cam design; one cam accessed the valve train and the other took care of the actuating injectors.
What this does is lower the combustion chamber temperatures limiting the formation of NOx. A neat concept but there were many issues with this system that caused many engine failures. The main point of failure is the dual overhead cam design which overly complicated things and caused many snowball effect types of issues in the engine.
In Cummins re-designed the ISX with a single overhead design to simplify things but the damage was done. This was supposed to be Cummins entrance into the electronic world however it was much too complicated for its own good. It is rightfully so belongs off the best diesel engine list; disappointing indeed.
Fun fact of the day: the Detroit Diesel Series 60 was mostly developed by John Deere although how much of an influence Deere had is debatable.
GM knew the company was in trouble and sought out help from John Deere engineers to re-establish their reputation. However the joint venture never came to fruition but the engine control technology took off. The first diesel ECM was wildly popular with consumers due to its ease of use and updates in real time to the driver.
Functions in the DDEC system included engine diagnostic functions, shutdown timers, progressive shift functions, fault history and record keeping, speed limiting governors, cruise control and automatic stall preventing. The cruise control technology was particularly popular with fleet managers due to its fuel-saving function but most notably DDEC system allowed the operator to download engine management reports regarding use of the engine, provide record of over-speeding, excessive idle time, hard breaking and other parameters.
The DDEC allowed dealers to change the horsepower settings and in some cases propriety software was able to be loaded into the computer. The system was easy to operate and diagnostic codes were displayed to the driver in real time: red indicator lights signaled a major problem while a yellow light was less of a serious issue.
The DDEC boom set in motion the electronic era for diesel engines. The Series 60 was first major diesel engine that did open the lead cam on the bigger bore. There are millions of Detroit Diesel Series 60 engines still on the road today and it is extremely easy to remanufacture Detroit Diesel Series 60 engines due to their unrestricted open source design.
For 20 years Freightliner and Penske trucks all had exclusive contracts to include Series 60 engines in their trucks. All heil the king of diesel, may it continue to live in the history books as the best diesel engine in the world. Good stuff but technology has surpassed these old engines. The old two stroke technology is easy to work on but boy that stuff is past its prime. Well there you have it: the best diesel engines of all time… followed by the subsequent worst diesel engines.
Let the discussion begin!
The most popular heavy-duty engine in North America, the X15 is capable of powering premium motorhomes of any size with up to hp and lb-ft of peak torque. The X15 also has best-in-class braking horsepower, for greater vehicle control. The X12, with up to hp and lb-ft of peak torque, is the lightest engine in its class. Ideal for larger luxury motorhomes, with the highest power-to-weight ratio so you can easily accelerate on short highway on-ramps, even while towing a car, boat or trailer.
The L9 has provided 30 years of continuous improvement. The XPI fuel system enables quiet, responsive operation while replaceable wet liners, roller followers, bypass oil filtration and targeted-piston cooling result in extended life and higher resale value. The L9 has ratings ranging from hp with up to lb-ft of peak torque. The B6. If the maximum road speed is able to be maintained one gear down, the gear-down protection feature should be set approximately 4 mph below the maximum road speed setting.
The gear-down feature will ensure that the vehicle is in top gear before the maximum road speed can be reached. The following charts list some of the acceptable combinations for top gear road speeds between 55 and 60 mph with approximate engine speeds in the rpm range. These gearing combinations provide the full advantage of the performance and fuel economy benefits of the ME Plus engine. The ME Plus with rpm governed speed is ideally suited for vocational applications.
The higher governed speed matches well with overdrive and deep-reduction ratio transmissions. Vocational applications require special attention to low-speed maneuverability and startability. Therefore, the overall gear reduction lowest transmission gear x rear axle ratio for mechanical transmissions should be approximately:. This engine rating delivers outstanding performance in the rpm range. The road speed governing feature of CELECT Plus provides precise control of top road speed and further improves fuel economy and performance.
The following charts list some of the acceptable combinations for top gear road speeds between 55 and 62 mph with approximate engine speeds in the rpm range. These gearing combinations provide the full advantage of the performance and fuel economy benefits of the ME Plus.
