Yuchai YCK15N: Gas Engine with the Largest Displacement and Maximum Torque in China Is Not Afraid of the Challenge of Life Forbidden Zone

End of September，Carry YuchaiYCK15N 570hp Shaanqi Commercial Vehicle Wing 3 LNGThe Tractor successfully climbed to the top of the Tanggula Pass, the highest elevation of the Qinghai-Tibet Highway at 5231 meters.。This is the Yuchai gas engine.YCK15NOne of the most rigorous real car tests ever conducted。Before，The gas engine completed the high temperature test of minus 40 degrees Celsius and 45 degrees Celsius.，As well as a total of more than 10 million kilometers of comprehensive road test.。

This plateau test trip，The convoy departed via Golmud at an altitude of 2,800 meters.，It passes through the Kunlun Pass, 4768 meters above sea level.，Turn over five beams in the middle、Cross the Tuotuo River，The final destination is the Tanggula Pass, 5231 meters above sea level.。After doing the test，Turn back the way you came，The whole journey is about 1200 kilometers.。The whole trip is not only high altitude.，The temperature difference between day and night is large，And the road conditions are bad，The climate is fantastic and unpredictable，Pass through many unpaved off-road surfaces，It is a severe test for both people and cars.。

Facing an altitude drop of more than 2000 meters，With YuchaiYCK15N 570 horsepowerLNGThere is no obvious power attenuation of the Tractor.。Liang Shizhou of Yuchai R & D team participated in the plateau trip.，He said，To verify Vehicle performance，From Wudaoliang to Tanggula Pass，The average altitude is 4500 meters.，Climb all the way，Overtake all the way。The industry's largest displacement is 14..8L、Maximum torque 2750N·mYuchaiYCK15NThe gas engine has shown an excellent power level.，The whole Vehicle speeds up quickly、The output is stable，It's easy to climb，The application of gas engine in Qinghai-Tibet line has become a reality.。
