Cummins has a full range of diesel engines for trucks, with a power range of 107 to 600 HP, which are widely used in heavy trucks, medium trucks and light trucks. Cummins X-Series engine is a global platform of Cummins. Since it was offline in 1998, X-Series is undoubtedly the most popular legendary engine platform loved by drivers and fleet operators. From 2007 to 2016, it has maintained the position of the first power in North American heavy truck market for 10 consecutive years.

Cummins ISX Diesel Engine

Cummins heavy truck diesel engine currently has five series of ISL, ISG, ISM, ISZ and ISX, with a power range of 308-600 HP, which can provide a complete set for heavy truck series Cummins ISX15l engine has unique advantages in low speed and high torque. When the engine torque is more than 2600 n · m, the corresponding speed range is wide, which can reach 1100-1500 rpm. When climbing or heavy load, the shift frequency can be reduced to ensure the transportation power of the whole vehicle. The company has adopted many patented technologies and advanced production processes of Cummins, achieving new breakthroughs in improving power and torque, fuel economy, controllability and reliability.

Features of Cummins ISX15 Engine

Feature 1: maximum power 600 HP, maximum torque 2779nm.

Feature 2: the best-selling power brand in the heavy truck market in North America for 10 years in a row. Almost every American truck brand provides Cummins X series engine for option.

Feature 3: XPI ultra-high pressure fuel injection system can carry out multiple injections in each working cycle to achieve a more stable and quiet working state. Cummins VGT turbocharger not only responds to the action of throttle rapidly, but also improves the brake power of engine.

Cummins ISX Injector

Cummins ISX injector is an important part of the fuel supply system of the Cummins ISX diesel engine, which is an important link to ensure the normal and orderly operation of the engine. If Cummin ISX injector fails, the engine will not operate as usual. As the "heart" of a car, if it can't work, there will be no power source for the car.So it is very important to choose a good Cummins ISX injector.

Tips For Cummins ISX Injector

Cummins ISX Injector is one of the three pairs of precision parts in the fuel supply system of ISX diesel engine. Its normal service life is more than 1000 hours. However, due to improper use, it is often used for hundreds of hours, or even dozens of hours.

I. Main Causes Of Stuck Fuel Injection Nozzle:

1. The diesel oil is not clean and there are impurities in the high-pressure oil pipe, which makes the needle valve couple not closed tightly. The high-pressure gas in the combustion chamber reverses and burns the needle valve couple. In addition, the dirt on the pressure regulating spring, tappet and other parts of the injector moves to the upper part of the needle valve of the injector through the tappet of the injector, or the cotton rope and lead wire used to prevent oil leakage enter the injector through the high-pressure oil pipe, which will cause the needle valve parts to be stuck.

2. The temperature of the machine is too high and the cooling of the fuel injector is poor, which causes the needle valve couple to be stuck. However, the engine will overheat if the oil supply time is too late, the scale in the cooling water channel is too much or blocked, the end face of the water pump impeller is worn, and the engine is overloaded for a long time.

3. The oil outlet valve is worn, which causes oil dripping when the fuel injector stops fuel injection, so that the fuel injection curved nozzle burns coke and deposits carbon, resulting in stuck fault.

4. When the injector is installed, the missing gasket or gasket is damaged, causing air leakage, causing the local temperature of the injector to be too high and stuck.

5. The injection pressure is too low, which causes the high-pressure gas in the combustion chamber to reverse;

6. Reasons for parts manufacturing, such as tight fitting between the injector mounting hole on the cylinder head and the injector, too small clearance between the needle valve body and the mounting hole on the cylinder head, too deep machining of the injector mounting hole on the cylinder head, etc.

II. Repair Method For Stuck Injector 

Put the stuck injector into diesel oil or engine oil for heating first, then take it out and wrap it with cloth, then clamp the needle valve with pliers and move it slowly to take the needle valve out of the needle valve body. Drop a small amount of cleaning oil into the needle valve body, so that the needle valve can move repeatedly in the needle valve body until the needle valve can move freely in the needle valve body. If the sealing surface of the needle valve has burn marks, it should be ground with grinding paste. When grinding, pay attention to the amount of grinding paste and grinding time. Install the cleaned needle valve coupling on the fuel injector and adjust the injection pressure before reuse.
