[Example: Engine Model Name WG972-GL-E4-XXXX]
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 displacement and output classification.
Over the past several years, KUBOTA has been supplying SI engines that comply with regulations in the
respective countries affected by Non-Road 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 Engine Displacement and 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.

[4] CYLINDER NUMBER

Any modifications to the tamper resistance parts on this engine

(1) "E4" engines are identified with "EF" at the end of the Model designation, on
the US EPA label.
"E4" designates EPA Tier 3 / CARB Tier 4 models, depending on engine
displacement and output classification.
The cylinder numbers of KUBOTA gasoline, gasoline / LPG and
natural gas engine are designated as shown in the figure.
The sequence of cylinder numbers is given as No.1, No.2 and
No.3 starting from the gear case side.
