Recently, there have been a number of technological breakthroughs in the field of engineering machinery engines. High-efficiency and low-emission products are accelerating to seize the market and promote the industry to upgrade to green and intelligent directions.
According to industry data, engines equipped with high-pressure common rail fuel systems and intelligent electronic control technology have a market share of more than 70%. Weichai's newly launched WP13G engine has a power range of 460-560 horsepower. By optimizing the combustion path, the fuel consumption rate is reduced to 195g/kW・h, which is 10% lower than traditional models. It has been equipped with a number of large-tonnage loaders.
With its 1600bar high-pressure injection technology and modular design, Doosan DV11 engine has seen a 28% month-on-month increase in orders in the field of mining machinery. Its integrated remote diagnosis function can monitor core parameters in real time, and the accuracy of fault warning has increased to 92%.
In addition, the pace of new energy power integration has accelerated. The diesel-electric hybrid engines launched by some companies have achieved 30% fuel savings in short-distance engineering machinery. They have been piloted in ports, municipalities and other scenarios. Industry experts said that technological innovation is becoming the core of competition among engine companies and will continue to drive the overall performance improvement of construction machinery.
