The 3306B engine is a multi-purpose medium-power heavy-duty engine based on construction machinery. It is widely used in construction machinery, trucks, generator sets, marine units and other industrial devices. Known for its high reliability and long life, the engine has the world's highest international market share.
The C6121 engine fully adopts the design, manufacturing and management technology of Caterpillar's 3306B engine, and also introduces product test equipment and processing equipment of main parts. In order to fully guarantee the same performance and reliability of C6121 engine and CAT3306B engine, except that the domestic production is approved and strictly implemented according to CAT 1E standard, key parts such as high-pressure injection pump, injector and high-pressure oil pipe are still imported directly from Caterpillar.
