The Cat 329D engine, C7 with ACERT technology delivers higher engine power and runs at lower speeds, resulting in improved fuel efficiency and reduced wear. Cat C7 uses electronic controls to manage the mechanical electronic unit injector (MEUI) system. Multi-point injection fuel delivery provides high-precision injection. Precisely tailoring the combustion cycle can reduce the temperature of the combustion chamber, reduce emissions and obtain the best combustion efficiency. This can convert fuel cost inputs into higher output.

The 329D hydraulic system and spare parts are reasonably designed to provide a high level of system efficiency. The main pump, control valve, and hydraulic oil tank are located close to each other, so that the connecting pipelines between the parts are shorter, thereby reducing the friction loss and pressure drop of the pipelines.
