Engine valvetrain systems have become more capable and increasingly more compact in the quest to improve efficiency. The developments parallel the advancements in other key engine components such as fuel injection or spark systems, turbocharging, aftertreatment, base engine and controls. While the gasoline sector has seen a steady rise in the adoption of Variable Valve Actuation (VVA), Diesel systems have lagged behind and only a few systems have seen production. The level of VVA activity however in the Diesel sector is beginning to increase as tighter regulations of CO2 emissions approach. Valve control plays a strong role in a number of key areas: turbocharger systems, allowing for better optimization matching across wide engine operating flows; enabling advanced combustion strategies where control over the charge mass and temperature are important; and cold start, where valve timing can be extremely effective for engine warm up compared with other strategies that rely on additional fueling.
This seminar will cover the range of Variable Valve Actuation technologies present in the market, their operation principles, and their effect on engine performance. Both gasoline and Diesel applications will be covered including how they impact the in-cylinder combustion as well as the aftertreatment. Participants will have the opportunity to perform hands-on exercises to examine the effects of the engine valve profiles on performance and are asked to bring a laptop computer, with Excel, to the seminar for class exercises.
This seminar is designed for engineers, managers, and other technical personnel from OEMs and support industries concerned with the design and development of optimized diesel and spark ignition engine systems, including calibration, performance, fuel economy and emissions for passenger car, light truck and heavy duty engines. It will be particularly interesting to Diesel engineers who will likely adopt some of the technologies developed in the gasoline sector for further improvements in emissions control and gains in fuel economy. It will be also of interest to combustion researchers as VVA will play a strong enabling role to exploring advanced combustion strategies.
Some background in thermodynamics, IC engine performance and emissions will be helpful. Individuals who need more background should consider attending SAE seminar C0103 : The Basics of Internal Combustion Engines.
