What causes engine overheating? Engine oil, coolant… let’s check them one by one.

The engine is like the heart of a car, its importance is self-evident. Construction vehicles, mainly used in construction sites, often operate in harsh environments with heavy loads. What happens when the engine overheats?
There are generally two reasons for diesel engine overheating: first, an inadequate cooling system; second, a malfunction in the engine itself. So how do you determine the problem? Truck drivers can start troubleshooting from the following points.

Noise Source Analysis and Characteristics of Diesel Engines

The sound power level of a diesel engine is a core indicator for evaluating its noise performance. Relevant domestic and international standards—such as GB 14097-1999 “Noise Limits for Small and Medium Power Diesel Engines”, GB/T 14097-2018 “Noise Power Level Limits for Reciprocating Diesel Generator Sets”, and GB 11871-2009 “Airborne Noise Limits for Marine Diesel Engines”—all specify the sound power level of diesel engines.
