One of the engine energy-saving measures: Cooling Fans
With the technological development of truck engines, the design of cooling system fans in engine thermal
management systems has undergone significant changes, mainly in three stages: early rigid fans, silicone oil
clutch fans, and the currently advanced electromagnetic clutch fans and electromagnetic silicone oil clutch fans.
Don't underestimate this small fan. Researchers have found that rigidly connected cooling fans require 3-5% of
the engine's power, and even more than 10% in small-power engines, resulting in alarming fuel consumption.
In my country's complex climate, many northern regions experience temperatures below 10 degrees Celsius for
over 100 days, meaning the engine cooling fan is essentially working in vain, resulting in significant fuel waste.
Domestic engine manufacturers are opting for electromagnetic clutch fans and electronically controlled silicone
oil fans, which significantly improve fuel efficiency in high-altitude, cold regions and high-speed vehicles on flat
plains.
Another engine energy-saving measure: Intelligent Speed Control Technology
Intelligent driving refers to the use of intelligent programming to ensure that the vehicle can intelligently control
the engine speed according to the operating environment, providing excellent fuel economy regardless of
whether driving smoothly, going downhill, climbing hills, or pumping conditions. This is like having a virtual
trainer in every car to guide drivers on how to save fuel.
Engine Energy Saving Measure Three: Engine Parameter Matching The operating conditions of the superstructure
are completely different from those of driving. Although road conditions are diverse, the engine will always
maintain a certain load for a period of time without significant fluctuations. Pumping conditions, however, lack
any continuity. The load increases sharply when the piston pushes concrete, and decreases rapidly when
reversing. The engine needs to respond quickly to avoid drastic speed fluctuations. Therefore, an engine with
specially matched parameters is undoubtedly more fuel-efficient than a chassis that hasn't undergone any
treatment.
