1. Diagnosis and treatment of engine with normal low speed and short time high speed with too little smoke exhaust The engine idle speed is good, and the throttle speed can be increased rapidly. However, the continuous boom throttle speed is not easy to rise, the driving is weak, or the medium speed is not able to drive. This is caused by insufficient low pressure oil supply. Reason a. Fuel filter or the  oil-water separator is blocked. b. Low pressure oil circuit is not smooth. c. Insufficient oil supply in oil pump or the oil filter is blocked. d. The inlet valve of fuel tank cover is invalid. All of the above conditions can cause the fuel pressure of the low pressure oil chamber of the fuel injection pump to be insufficient, and only the oil supply amount required for the small load can be maintained. when It is necessary to use more oil supply for large and medium load, it cannot be satisfied, resulting in a weak driving. Diagnosis and treatment ...

Recently, a truck fleet, consisting three heavy-duty trucks and two light trucks, all of which are equipped with Cummins engines, successfully passed stringent tests in Tibet. The truck fleet, after traveling to 15 cities across China in nearly six months on a tour known as “100 Year Cummins, Beautiful China”, made the trip to Lhasa, the capital city of China’s Tibet Autonomous Region via Lanzhou and Golmud. Despite a number of challenges posed along the trip by the high altitude and long distances, Cummins Z14 and F4.5 engines, both fully meeting National VI Emission Standards, delivered stable and consistently powerful performances along the 7,000 km-plus trip. On August 12, Cummins Z14 engine mounted on Dongfeng Tianlong flagship truck, Cummins F4.5 engine mounted on Foton Aumark, Cummins X12 engine mounted on Foton-Daimler self-dump truck were all put on display in Lhasa. They were all there for trial operation by customers, attracting wide media attention. On ...

Firstly, when choose engine lubricating oil , can not choose and know about engine lubricating oil correctly. As we know, about vehicle diesel engine oil, we should choose different grades of oil according to different types of diesel engines and different operating conditions. While, for different proportion of additives, grades of diesel oil is also different. For example, CC diesel engine lubricating oil and CD diesel engine lubricating oil. While manufacturers produce diesel engine lubricating oil according to different brands of diesl engine and demands, forming their own formulation systems in the formulation process . Lubricating oil is made by base oil and additives. Although the quality of lubricating oil depends mainly on the base oil, additives also can not be ignored. In the daily use of lubricating oil, because the different brands of lubricating oil produced by different manufacturers are mixed together to use, it is chemical reaction between additives, resu...

In this article, you will learn  Cummins  NT series diesel engine maintenance checks. If you are looking for the knowledge, why not take a few time to read it? At each “D” Maintenance Checks, perform all “A”, “B” and “C” checks in addition to those following. Most of these checks should be performed by a Cummins Distributor or Dealer and where Cummins Shop Manuals are available for complete instructions. Clean and Calibrate Injectors Clean and calibrate the injectors regularly to prevent restriction of fuel delivery to the combustion chambers. Because of the special tools required for calibration, most owners and fleets find it more economical to let a Cummins Distributor do the cleaning and calibration operations. To clean and calibrate the injectors from Engines for cleaning the seal seat should be removed from the injector (1, Fig.2-22) or injector “well” for cleaning, examination and or replacement as necessary.

B-Check At each “B” Maintenance Check, perform all “A” Checks in addition to the following. Maintaining a proper “B” maintenance check interval is a very important factor in preserving the integrity of an engine . Lubricating oil contamination is the direct result of engine operation, the load factor involved and the amount of fuel the engine consumes. Note:  If the lubricating oil is drained from the oil pan to make an engine repair, new oil must be used. Do not use oil after it has been drained from the oil pan. Lubricating Oil Change Intervals 1. The recommended oil change interval is determined by the “Chart Method” based on fuel oil consumed and lubricating oil added. See “Chart Method” following. 2. An alternate to the “Chart Method” is 250 hours or 6 months. 3. A second alternate method of determing oil change interval may be established through the use of oil analysis. Refer to “Lubricating Oil Analysis.” Chart Method Advancement in lu...
