A Legacy of Detroit 创新: Top 5 Diesel Technology Milestones
你很难错过半挂车. After all, they are the giants of our roads. 的y keep shelves stocked, vehicles 燃料ed and businesses going strong. On the outside, they’re one of the most visible symbols of a healthy economy.
And yet, there’s much more happening on the inside of a semi truck. Under the hood, there is a constant, invisible evolution at play. An evolution that’s quietly improving diesel engine efficiency, lowering total cost of ownership for fleets and powering commerce with cleaner diesel technology than ever before.
So let’s take a look at Detroit’s legacy of diesel innovation. Here are five of the most significant advances that we’ve made over the past 80-plus years:
1. 53系列，71系列和92系列
Powering Commercial Trucking to Greater Lengths
在韦德手机，创新根深蒂固. It’s a legacy that goes all the way back to 1938, when General Motors formed the GM Diesel Division and supported the construction, mining and military sectors with two-cycle diesel engines.
One of the first great strides in diesel engine technology was made in 1957 with the launch of the Series 53. 这个可靠的, two-stroke engine opened up vast opportunities for a range of commercial trucking applications. 为开阔的道路而建, 它提供了更好的性能, 燃料 efficiency and durability than previous generations of two-cycle engines.
Soon after, the two-stroke, V-type Series 71 began to find solid use in long-haul operations. 1974年, 92系列, 哪个是在71的核心设计上建造的, was released to meet the increasing demands of heavy-duty and long-haul trucking.
2. 系列60®(1987)
Activating New Possibilities with Electronic Controls
的 系列60 took diesel engine technology even further. As the first diesel engine to feature electronic controls, it offered easier serviceability and helped lead the industry toward a more 燃料-efficient, 低排放设计. What was once a next-generation advancement quickly became a trusted standard throughout the 1980s. Evidence of its popularity – and longevity – can be seen in those who run older-model trucks today.
3. 发动机后处理韦德手机app(90年代)
引领低排放之路
Emissions control has come a very long way over the last several decades, with groundbreaking advances in engine and exhaust aftertreatment systems. While emission control systems have become the industry standard for diesel engines, our engineers have also made strides in reducing their impact on daily operations.
的 new Detroit Aftertreatment System (ATS) does more with less. 该系统的特点是单, large Diesel Particulate Filter (DPF) with Asymmetric Cell Technology for increased service intervals. Asymmetric injection activates as an engine warms up and prolongs the life of the ATS by increasing heat when necessary. Detroit engines also offer 的rmoCoast – keeping temperatures up during low load driving, expediting the regen process and reducing time and energy previously spent on the ATS.
从20世纪80年代末开始, EPA limits for two key emissions constituents, nitrous oxide (NOx) and particulate matter (PM), 下降了98%. 随着法规的不断发展, Detroit is committed to staying out in front and leading the way to an even cleaner diesel future, 不仅要遵守法律条文, 还有它的精神.
4. DD15®韦德手机(2007)
建立全球柴油基金会
的 DD15 kicked off the DD engine lineup with a completely reimagined engine, 燃料, 空气及后处理系统设计. 更省油, 可靠性和耐久性, as well as significantly improved emissions, the DD15 set the standard for diesel technology, introducing more than one million engines across the globe on its platform.
5. DT12®(2012)
用连通性改变游戏
的 DT12 marked a significant step forward in truck-engine connectivity, allowing for improved diagnostics and maintenance as well as seamless integration of safety systems. Greater connectivity also marked a significant step forward in performance and paved the way for the 一体化韦德手机动力总成.
Diesel: A Vital Part of a Cleaner, More Efficient Tomorrow
At Detroit, the past is full of diesel innovations. 未来也是如此. Ever-cleaner commercial vehicle technology and reduced total cost of ownership will continue to play a crucial role in the evolution of how semi trucks drive commerce. So, when you think about tomorrow, you might wonder: is it diesel or electric? 的 answer is “yes” – and we’re ready to advance the industry on both fronts.
创新. 这是一项从未完成的工作.
效率. 表演. 可靠性. 的se are the qualities that have defined Detroit craftsmanship and technology for the past 80-plus years. And they are what continue to make our lineup of heavy-duty engines the industry leader today. 回首过去, one thing is clear: innovation isn’t a collection of milestones to hang your hat on. It’s a journey of constantly working to discover what world-powering technologies lie just around the corner.
