The Carter 3408 engine adopts a four-stroke, water-cooled, in-line design, featuring 8 cylinders with a bore of 140 mm, a stroke of 153 mm, a total displacement of 5.08 liters, and a maximum torque of up to 730 N · m. The Carter engine adopts advanced fuel injection technology. The water cooling system of the Carter engine can effectively dissipate excess heat, keep the engine temperature within the normal range, and further improve fuel economy and reliability. The Caterpillar 320 May also have a good design in terms of heat dissipation and thermal management to ensure that the engine operates at the optimal working temperature. Carter engines are designed with high-quality materials and components, and go through strict manufacturing and testing processes to ensure high reliability and long service life. The overall structure and key components of Carter 320 May also follow such standards and be able to maintain stable operation even in harsh working environments.
