A one-way journey of 2,500 kilometers, half on national highways and expressways, consistently carrying a full load of 30 tons, crossing the Tianshan Mountains-this is driver Yu's daily routine in Ningxia.
On this industry-recognized tough test ground in Xinjiang, Yu and his newly acquired Shaanxi Automobile Longxiang equipped with Cummins' 15N FE natural gas engine have delivered results exceeding expectations.
Climbing long slopes with fully loaded
This was Yu's first time using a Cummins natural gas engine, and he initially had some reservations. But once he hit the long-haul route to and from Xinjiang, those doubts quickly turned into delight. Under the same load conditions, the Cummins 15N FE natural gas engine demonstrated noticeably stronger uphill performance, accelerating smoothly without hesitation, and maintaining consistent power even over extended climbs. Thanks to mature stoichiometric combustion technology and an efficient turbocharger, the engine delivers stable, enduring power output. Even during long-distance, fully loaded ascents, frequent downshifting isn't necessary, effectively reducing pressure from tight delivery deadlines at border checkpoints and ensuring reliable long-haul transportation efficiency.
Is fuel consumption really low?
Yu frequently travels between southern coastal regions and Xinjiang borders, facing not only extreme temperature differences and diverse road conditions but also harsh challenges such as traversing deserts, climbing mountain ranges, and operating around-the-clock. These demands place significant stress on the fuel economy stability of natural gas vehicles. The 15N FE engine incorporates multiple fuel-saving technologies that precisely maintain optimal economic operating conditions, enabling more complete fuel combustion. As a result, each trip saves considerable amounts of natural gas, delivering tangible cost advantages to Yu.
Reliable power means peace of mind on border routes.
In border transport operations, vehicle reliability directly impacts delivery timeliness. A breakdown can lead to high repair costs and potentially incur immeasurable losses due to delayed customs clearance. Yu's vehicle has now accumulated over 130,000 kilometers under heavy-duty use, yet the engine has never broken down unexpectedly or required major overhauls. Combined with Cummins' professional and prompt after-sales service, Yu enjoys far fewer worries while on the road.
Powerful, fuel-efficient, and dependable, the Cummins 15N FE natural gas engine excels in every aspect.
