For the construction equipment industry, the 320D/320DL is definitely not unfamiliar. This 20-ton excavator, which has topped the ownership charts for many years, is a preferred choice for most construction projects, whether in mining, earthworks, or urban construction, thanks to its durable body and ability to adapt to various working environments.

Its equipped C6.6 electronic control common rail engine offers strong load capacity and fuel efficiency. The matching fuel injectors also require high-quality standards to support high-intensity work modes.

For example, our fuel injector 306-9390, after production, goes through multiple layers of testing to ensure strict internal tolerances, preventing oil leakage and carbon buildup, reducing maintenance costs, and stabilizing performance, ensuring the smooth operation of engineering projects worldwide.
