It has been demonstrated that the incylinder turbulence of a 4 valve engine with a swirl control valve (SCV) is enhanced by inclined swirl. This paper examines the effects on turbulence of varying ...

This SULEV/ULEV-compliant engine features 10.3:1 compression for improved power, continuously variable valve timing on both the intake and exhaust cams and a two-stage intake manifold plus swirl ...

Tumble and swirl motions in the cylinder of a four-valve SI engine with production type cylinder head were investigated using a cross-correlation digital Particle Image Velocimetry (PIV). Tumble ...
