Authors Abstract
Content
This paper outlines a vision of future engine requirements and operating strategies to reduce fuel consumption and engine out emissions. It discusses in detail the valve operating strategies used to achieve throttleless spark ignition (SI) load control and two methods of controlled Auto Ignition (AI). Emission and fuel consumption speed load maps are shown and differences between SI and AI maps are discussed. Many fully variable valve-timing strategies are proposed and conclusions are reached that clearly indicate significant improvements in IC engine performance are still achievable.
