E-TVCS Technology for the clean age. 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.
The new TVCS added a special concave recess on the piston head to force compression air in the swirl chamber and to smooth combustion gas exhaust. The E-TVCS, based on the new TVCS, is aimed at a drastic emission reduction.
E-TVCS (IDI) E-TVCS produces far less soot, HC and CO thanks to a better match between the injection nozzle throat and the concave recess on the piston head. The injection pump and nozzle are better matched with the combustion chamber to reduce NOx emissions.
Meets all applicable emissions regulations world wide.
More Comfort from Less Noise
In order to improve the already well-established lower noise levels of the existing engines, Kubota added a half float head cover, and a MoS2 coated piston to the Z602 and the D902.
Half Float Valve Cover The rubber ring seals and isolates vibration and reduces the noise from the crankcase. As a result, the noise level is 1.0~1.5dBA lower than that of the conventional models in the same class.
Other Features
MoS2 Coated Piston - Sulfureted molybdenum coating enables clearance reduction between the piston and the cylinder liner, thus optimizing the oval shape ratio and decreasing the piston slapping noise. Quick Start ups - Super glow system comes as standard equipment to shorten preheating time and quicken engine start up in cold temperatures. Highly Reliable Engine - based on Kubota's original sturdy design, the engine promises great reliability and long service life.
