Commerc
30、ial vehicles are used for a wide range of duties, including transporting goods or people and infrastructure service. In 2010, the worldwide production of commercial vehicles exceeded 19 million units. Commercial vehicles transported over half of the value traded by the United States with Canada and
31、Mexico. Over the last 100 years, the powertrain of commercial vehicles has seen continued development since the late 19th Century invention of the gasoline- or diesel-fueled internal combustion engine. In 1904, Ferdinand Porsche built the first hybrid vehicle that housed electric motors in the front
32、 wheel hubs while a gasoline-engine-powered generator provided power. During the first decade of the 1900s, both General Electric in the United States and Siemens in Germany produced hybrids as commercial vehicles. In the 1920s, heavy- duty commercial vehicles were firmly established as a major mean
33、s of freight conveyance. Diesel engines, invented and first built by Dr. Rudolf Diesel in 1897, have been used in large trucks since the 1930s in the United States due to their larger torque and higher thermal efficiency compared to gasoline- powered engines. In the early 1970s, concerns emerged ove
34、r growing dependence on imported petroleum and deteriorating air quality due to emissions from fos- sil fuel combustion. In response, the U.S. Congress passed the Electric and Hybrid Vehicle Research, Development worsening pollution and traffic congestion in major cities demand that sustainable tran
35、sportation solutions be explored. In addition to the IC engine hybrid powertrain, further powertrain improvement technologies may include the utilization of various fuel sources with optimized energy conversion efficiency. This can include plug-in hybrid, range extender electric, and pure electric v
36、ehicles. Other options are mul- timodal transportation with intelligent transportation technologies, smart grid, advanced energy storage technologies, and intelligent electric charg- ing infrastructure. Sustainable transportation may also include renewable resources such as biofuels, or energy deriv
37、ed from solar, wind, or geothermal sources. Reduction of energy demand through government policy and incen- tives, advanced transportation planning, and public awareness and participa- tion is another option. This book, Advanced Hybrid Powertrains for Commercial Vehicles, pro- vides a broad and comp
38、rehensive insight into hybrid powertrain technologies for commercial vehicles. Based on the authors extensive experiences in devel- oping advanced powertrain technologies, this book explains the fundamentals of hybrid powertrain systems, government regulations, and driving cycles. It provides design
39、 guidelines and describes key components to prospective engineers and developers, powertrain researchers, engineering students, poli- cymakers, and business executives in the commercial vehicle and transporta- tion industries. Chapter 1 introduces the basics of commercial vehicles, including the dev
40、elopment history of commercial vehicles, classification, driving cycles, regulations, the fundamentals of powertrain hybridization, and various hybrid system technologies, including the hybrid-electric powertrain, hybrid hydrau- lic powertrain, and hybrid pneumatic powertrain. This chapter also anal
41、yzes the advantages and disadvantages of various hybrid technologies for different driving cycles and applications. Chapter 2 describes basic concepts and new developments of internal com- bustion engines for the commercial vehicle market, such as HCCI and low- temperature combustion, emission reduc
42、tion technologies, urea-based SCR and LNT NOx aftertreatment technologies, DPF systems for PM reduction, etc. Chapter 3 introduces the basics of clutches and transmissions for com- mercial vehicles. It discusses the basic design principles and characteristics of clutches and manual, automated manual, and automatic transmissions; double clutch transmissions (DCTs); and continuously variable transmissions (CVTs).
