The emission controls previously implemented in
various countries to prevent air pollution will be stepped
up as non-road emission standards continue to change.
The timing or applicable date of the specific non-road
emission regulations depends on the engine output
classification.
Over the past several years, Kubota has been
supplying diesel engines that comply with regulations in
the respective countries affected by non-road emission
regulations. For Kubota Engines, E4B will be the
designation that identifies engine models affected by
the next emission phase (See the table follows).
When servicing or repairing ###-E4B series engines,
use only replacement parts for that specific E4B
engine, designated by the appropriate E4B Kubota
parts list and perform all maintenance services listed in
