Newest developments

For off-road vehicles, today the company produces Tier 1 - Tier 3 environmental standards aggregates with electronic or mechanical control meeting the requirements for emissions toxicity in various regions of the world. Since 2014, Cummins Inc has commenced the serial production of the Tier 4 Final and StageIV range of industrial engines.

Updated products were successfully presented at the largest international exhibition of industrial equipment ConAgg / CONEXPO, held in March 2014 in Las Vegas. One of the novelties introduced to the market was the new family ISG / QSG (working volume 11.8 liters).

The main innovation, introduced in the G series, was unique design solutions that allowed the new product to be the best steel in terms of specific power, reaching an unbelievable 862 kg for the engines of this capacity. The most balanced engine is the Cummins QSG12, which pushed the competitors in the market for tractors, combines, loaders, cranes, excavators and other road construction equipment.

Repair and diagnostics

It should be noted that the American products are technologically complex, therefore it is recommended to repair Cummins engines from certified dealers. Used in engines with electronic control system Quantum allows you to bring the power characteristics of power units in accordance with individual loads on the equipment and requirements for emissions of harmful substances into the environment.

Additional features:

• The Cense diagnostics system monitors the main engine parameters, monitors the trends of their changes, allows diagnosing the defects that occur and determines the time of the maintenance.
• The Insite software provides step-by-step engine diagnostics and allows accurate troubleshooting.
• To improve the performance of engines, it is necessary to eliminate the need to change the oil or repeatedly increase the interval of its replacement. With the help of the modern Centinel oil change management system, the company has already reached the oil change interval of about 4000 hours, and the interval for changing the oil filter is up to 1000 hours.
• Self-cleaning automatic filtering system Eliminator allows you to abandon the replaceable oil filters: two-stage filtration system is able to work the entire life of the power unit.

Cooperation with Russia

Cummins Inc, the first of the foreign TOP companies, localized the production of industrial engines in Russia - the partner was KamAZ. The first in the series went the legendary line "B" (power 140-300 hp), which brought fame to the brand Cummins. Parts, units and assemblies were mostly produced at domestic facilities.

In 2014, the production of the QSB6.7 model with a capacity of 180-260 liters was mastered. from. Concern "Tractor Plants" was the first to apply these engines on bulldozers T-11.02 manufactured by "Promtractor".
