E4 Engine - Kubota EA330-E4 Series Workshop Manual

EA330-E4, WSM

[2] E4 ENGINE

[Example: Engine Model Name EA330-E4-XXXX]
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, E4 will be the designation that
identifies engine models affected by the next emission phase (See the table below).
When servicing or repairing ###-E4 series engines, use only replacement parts for that specific E4 engine,
designated by the appropriate E4 KUBOTA Parts List and perform all maintenance services listed in the appropriate
KUBOTA Operator's Manual or in the appropriate E4 KUBOTA Workshop Manual. Use of incorrect replacement parts
or replacement parts from other emission level engines (for example: E3 engines), may result in emission levels out
of compliance with the original E4 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. E4 engines are
identified with "EF" at the end of the Model designation, on the US EPA label. Please note: E4 is not marked on the
engine.
