[2] E4B ENGINE
[Example: Engine Model Name V2403-CR-TE4]
The emission controls previously implemented in various countries to prevent air pollution will be stepped up as
Nonroad Emission Standards continue to change. The timing or applicable date of the specific Nonroad 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 Nonroad Emission regulations. For KUBOTA Engines, E4B will be the designation
that identifies engine models affected by the next emission phase (See the table below).
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 the appropriate
KUBOTA Operator's Manual or in the appropriate E4B KUBOTA Workshop Manual. Use of incorrect replacement
parts or replacement parts from other emission level engines (for example: E3B engines), may result in emission
levels out of compliance with the original E4B design and EPA or other applicable regulations.Please refer to the
emission label located on the engine head cover to identify Output classification and Emission Control Information.
E4B engines are identified with "EF" at the end of the Model designation, on the US EPA label. Please note: E4B is
not marked on the engine.
