Integrated system engineering for valvetrain design and development of a high-speed diesel engine

The lead time for engine development has reduced significantly with the advent of advanced simulation techniques.

With vehicle emissions norms becoming more stringent and a global focus on CO₂ reduction, there is an increasing need for original equipment manufacturers (OEMs) to develop engines that are smaller and more efficient. The industry thus can expect an increasing trend in engine design toward downsizing and weight reduction.

The demand for increased specific output dictates a robust valvetrain design that facilitates effective engine breathing. In this study we discuss a novel approach to the design and development of a valvetrain system for a 1.0-L high-speed diesel engine, as described in Fig. 1.
