Recently, the engineering machinery engine industry has ushered in a peak of technological iteration. Many companies have released new products that meet the National IV emission standards, and high efficiency, energy saving and intelligence have become core competitive points.
Weichai's latest WP15H engine, through high-pressure common rail + high-efficiency SCR post-processing technology, covers a power of 480-600 horsepower, and the fuel consumption rate is 8% lower than the previous generation. It has been mass-produced for large excavators and cranes. Doosan DV11 series engines rely on V-type six-cylinder design and intelligent electronic control system. The order volume in the field of mining machinery has increased by 35% year-on-year, and its maximum torque of 1834N・m can adapt to heavy-load conditions.
Industry data shows that after the implementation of the National IV standard, the market share of engines equipped with intelligent diagnostic systems has increased to 62%. These engines can predict faults through remote monitoring, which can increase the equipment attendance rate by more than 15%. At the same time, new energy power has also accelerated its penetration, and the application of hybrid engines in municipal engineering vehicles has exceeded 1,000 units.
Industry insiders pointed out that the power system is transforming from "single power output" to "efficient energy management", and technological upgrades will drive the construction machinery industry towards low carbonization and high reliability.
