To validate the real-world application performance of the Yuchai K11 engine, an extensive in-service verification was conducted on intercity passenger transport vehicles. The test unit operates on routes connecting Manila and adjacent cities in the Philippines, where the road configuration comprises 80% high-speed highways with the remaining section comprising urban arterial roads, all characterized by excellent surface conditions. This setup comprehensively adapts to the rigorous daily operational demands of long-distance passenger transit.
The test vehicle is a Higer KLQ6126LY 12-meter passenger coach, exclusively powered by the Yuchai K11 engine. Mated to a Wanliyang (WLY) 6-speed transmission and a final drive ratio of 3.9, the integrated powertrain system ensures seamless power delivery and exceptional energy efficiency during high-speed cruising.
