Kubota Horizontal RK series

A wide range of diesel engines to satisfy any need, anywhere

TVCS System-TVCS for steady and efficient operation.
Kubota’s TVCS (Three-Vortex Combustion System) is a revolutionary system that creates three vortexes within the combustion chamber in order to produce an air/fuel mixture with a uniform spray and an optimum average particle size. This ideal air/fuel mixture, in turn, ensures complete combustion for greater power output and more steady operation.
