Fatigue is a structural failure mode that must be recognized and understood to develop products that meet life cycle durability requirements. In the age of lightweighting, fatigue strength is an important vehicle design requirement as engineers struggle to meet stringent weight constraints without adversely impacting durability. This technical concept course introduces the fatigue failure mode and analysis methods. It explains the physics of material fatigue, including damage accumulation that may progress to product failure over time, and it provides the needed foundation to develop effective fatigue prediction capabilities.

Regulations and consumer expectations have shaped the modern diesel engine. Enhancements have resulted in more power, fuel efficiency, reliability, and lower emissions, an indication that diesels will remain popular in the future. This technology is most widely used in commercial applications, such as trucking, shipping, construction, busing, and more. Each year, many light and medium duty car and truck manufacturers introduce diesel vehicles worldwide. A fundamental knowledge of diesel technology is critical for anyone involved in the diesel engine support industry.

Materials degradation from environmental conditions is a common factor that will often occur in mechanical equipment used in every type of environment. These processes can frequently materialize in unpredicted and harmful ways, especially when they interact and lead to early component damage or failure. Captured from five, two-hour sessions, this course summarizes the mechanisms that cause materials and mechanical components to degrade in service through exposure to deleterious mechanical and environmental conditions.

Turbocharging is an integral part of many internal combustion engine systems. While it has long been a key to diesel engine performance, turbocharging is increasingly seen as an enabler in meeting many of the efficiency and performance requirements of modern automotive gasoline engines. This replay discusses the basic concepts of turbocharging and air flow management of four-stroke engines. It explores the fundamentals of turbocharging, system design features, performance measures, and matching and selection criteria. Topics include spark ignition, diesel engine systems, and the impact of different applications.

Ferrous metals contain iron and are prized for their tensile strength and durability. Most are magnetic and contain a high carbon content which generally makes them, with the exception of wrought iron and stainless steel, vulnerable to rust. The following seven eLearning courses are included in the Ferrous Materials Bundle: Steel and Cast Iron. Each course is approximately one-hour in duration. Modules include: Introduction to Physical Properties, Introduction to Mechanical Properties, Introduction to Metals, Hardness Testing, Ferrous Metals, Classification of Steel, Essentials of Heat Treatment of Steel.

Vehicle functional requirements, diesel emission regulations, and subsystem thermal limits all have a direct impact on the design of a powertrain cooling airflow system. Severe duty cycles, minimal ram air, fouling, and sometimes unconventional package layouts present unique challenges to the designer. This course introduces many airflow integration issues and vehicle-level trade-offs that effect system performance and drive the design. The goal of this course is to introduce engineers and managers to the basic principles of diesel cooling airflow systems for commercial and off-road vehicles.

Getting the strength and hardness you need in your steel requires knowledge of the effects of alloy composition and heat treating on steel properties. With knowledge of steel metallurgy you’ll be better able to: Select the most appropriate alloy and heat treating process for your application Evaluate suppliers Develop manufacturing processes Solve quality problems A good understanding of what can be done to modify the properties of steel is critical for being more productive and profitable.

This web course provides an in-depth overview of diesel engine noise including combustion and mechanical noise sources. In addition, the instructor will discuss a system approach to automotive integration including combining sub-systems and components to achieve overall vehicle noise and vibration goals.
