03-M-E3B, 03-M-DI-E3B, 03-M-E3BG WSM G GENERAL [2] E3B ENGINE [Example : Engine Model Name D1803-M- E3B -XXXX or D1803-M-DI- E3B -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 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, E3B will be the designation that identifies engine models affected by the next emission phase (See the table below). When servicing or repairing ###-E3B series engines, use only replacement parts for that specific E3B engine, designated by the appropriate E3B Kubota Parts List and perform all maintenance services listed in the appropriate Kubota Operator's Manual or in the appropriate E3B Kubota Workshop Manual. Use of incorrect replacement parts or replacement parts from other emission level engines (for example:
E2B engines), may result in emission levels out of compliance with the original E3B 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. E3B engines are identified with "ET" at the end of the Model designation, on the US EPA label. Please note : E3B is not marked on the engine. (1) EU regulation engine output classification category (2) “E3B” engines are identified with “ET” at the end of the Model designation, on the US EPA label. “E3B” designates Tier 3 and some Interim Tier 4 / Tier 4 models, depending on engine output classification.
