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.
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. E-TVCS meets all applicable emissions regulations world wide.
The injection pump and nozzle are better matched with the combustion chamber to reduce NOx emissions.
Half Float Valve Cover - 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 these engines.
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.
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.
