Journal ArticleDOI
Homogeneous charge compression ignition operation with natural gas: Fuel composition implications
TL;DR: In this article, the effect of fuel composition on combustion in homogeneous charge compression ignition (HCCI) engines is investigated, including the impact of various fuels and the sensitivity of engine operation for any given fuel.
Journal ArticleDOI
Exercise self-efficacy in adults with congenital heart disease
TL;DR: Age is an important predictor of low ESE and should be considered in counselling patients with CHD, and in addition, muscle endurance training may improve ESE, and thus enhance the potential for being physically active in this population.
Proceedings ArticleDOI
Ignition sensitivity study of Partially Premixed Combustion by using shadowgraphy and OH* chemiluminescence methods
TL;DR: In this paper, high-speed shadowgraphy is used to visualize fuel injection and evaporation at different start of Injections (SOI). Spray penetration and injection targeting are derived from shadow graph movies.
Journal ArticleDOI
The Low Load Limit of Gasoline Partially Premixed Combustion Using Negative Valve Overlap
TL;DR: In this article, the authors investigated different multiple-injection strategies in order to further expand the low load limit and reduce the dependency on negative valve overlap in a light duty diesel engine with a fully flexible valve train system.
Journal ArticleDOI

TL;DR: Sport participation appears to be the primary physical activity-related driver of perceived health status (PHS) in ACHD patients, and by promoting sport-related exercise ACHd specialists thus may improve PHS in A CHD patients.
