"The B3000 cab model tractors feature a smooth-running 30HP, 4-cylinder, liquid-cooled diesel engine, with Kubota’s E-TVCS (threevortex combustion system) for increased power and high torque."

Can anyone explan what this is and how the (threevortex combustion system) works ? to increased power and high torque ?..in a laymens terms please ?

Technology for a Cleaner Environment

Kubota's proprietary TVCS (Three Vortex Combustion System) obtains an optimum air/fuel mixture by generating three intense swirling air flows (vortexes) within the spherical-combustion (swirl) chamber.

TVCS has been a major feature of all Kubota Diesel Engines. Kubota then introduced an upgraded TVCS that added a special concave recess on the piston head to force compression air in the swirl chamber and to smooth combustion gas exhaust.

Now, the E-TVCS, based on the latest TVCS, is aimed at a drastic emission reduction.
