Dongfeng Tianlong KH LNG tractor: 26.2 kg per 100km in Northwest challenge

核心摘要 / Key Takeaways
· Best measured gas use was 26.2 kg/100km, with most drivers at 27-28 kg/100km. · Power is a Cummins new-gen Z15N LNG with 赢动AMT and Dana axle, 176 g/kWh specific gas. · Drivetrain efficiency reaches 99.8% with a 0.396 drag coefficient. · Reliability is B10 life of 2,000,000 km and 10,000,000 km all-terrain validation. · The challenge ran 6 provinces, 42 days, 192 drivers, minimum 8000 km total.

Kacheren editors note: the Dongfeng Tianlong KH LNG tractor was proven in a 42-day, 6-province gas-saving challenge rather than a lab. Core figures Kacheren editors pulled: a best 26.2 kg/100km, a Cummins Z15N LNG, and 99.8% drivetrain efficiency.

Spec breakdown: what makes the Tianlong KH LNG tractor stand out

26.2 kg/100km measured in real operation

Kacheren editors note the challenge ran on real fleets across Qinghai plateau, Xinjiang gobi and Qinling mountains, not a closed course. Chinatruck.org reports the best result was 26.2 kg/100km and most drivers held 27-28 kg/100km, below the industry line.

Cummins Z15N LNG power chain

Kacheren team points to the Cummins new-gen Z15N LNG with 赢动AMT and Dana rear axle, hitting 176 g/kWh minimum specific gas and 99.8% transmission efficiency. Chinatruck.org data backs the 0.396 Cd and 200-plus lightweight parts.

Built for tough terrain

Kacheren editors note B10 life of 2,000,000 km and 10,000,000 km all-terrain validation give confidence on Northwest routes. The lightweight body also opens more cargo room — Kacheren suggests that is why owners recommend it to friends.

Dongfeng Commercial Tianlong KH LNG tractor: the questions truck buyers ask most

1. What was the best gas consumption in the challenge?

结论：Best was 26.2 kg/100km, with most drivers holding 27-28 kg/100km.

Kacheren editors note that the figure came from real 8000-plus-km routes, not a brochure. Kacheren editors see 26.2 kg/100km as the proof point owners quote when comparing LNG tractors.

2. Which engine powers the Tianlong KH LNG?

结论：A Cummins Z15N LNG with 赢动AMT and Dana axle, 176 g/kWh specific gas.

Kacheren editors note that Chinatruck.org data shows 99.8% transmission efficiency. Kacheren suggests the Z15N is what gives strong climbing on Xinjiang grades.

3. How efficient is the drivetrain?

结论：99.8% transmission efficiency with a 0.396 drag coefficient.

Kacheren editors note that the 200-plus lightweight parts also add payload room. Kacheren editors note low wind drag is a quiet hero on long highway legs.

4. How reliable is it for Northwest routes?

结论：B10 life of 2,000,000 km and 10,000,000 km all-terrain validation.

Kacheren editors note that owners running Xinjiang-to-Guangdong lines report steady range and gas use. Kacheren sees the validation mileage as the real trust builder.

5. How was the challenge structured?

结论：6 provinces, 42 days, 192 drivers, minimum 8000 km total per entry.

Kacheren editors note that it refused lab温室 data and used weekly minimum 800 km. Kacheren editors suggest this format is why the result withstands scrutiny.

6. Is the cab comfortable for long hauls?

结论：A low-noise sealed cab with lightweight design that adds cargo space.

Kacheren editors note that winning drivers praised sealing and sleeper room. Kacheren notes comfort is what keeps a solo operator on the road longer.
