E-TVCS Technology Improves Engine Performance

The concave recess on the piston head helps Kubota’s E-TVCS (THREE Vortex combustion systems) generate three intense swirling air flows (vortexes) within the spherical-combustion chamber to obtain an optimum air/fuel mixture. This superb combustion system improves the power output, fuel economy, and engine startups, while reducing both noise and toxic emissions.
