Key Factors Affecting Fuel Consumption in Wheeled Excavators

In the current landscape inundated with wheeled excavator models, the focus on details, particularly fuel consumption, has intensified for both demanding customers and users. Fuel efficiency plays a crucial role in determining competitiveness and sustained profitability in the practical market. What are the key factors that decide the fuel consumption of wheeled excavators?

  1. Impact of Engine Displacement:

    The diesel engine's displacement used in wheeled excavators of around 8 tons is typically around 2000ml. While different brands may have varying displacement levels, these parameters must adhere to the objective environmental requirements of wheeled excavator models. Engine displacement appears to have a minimal influence on fuel consumption in similar wheeled excavator models due to the constraints of model types, power output, and operational interference.

  2. Influence of Operating Habits and Conditions:

    In mature wheeled excavator markets, experienced operators have started delving into practical data to address the fuel consumption issue. Variations in fuel consumption become evident when the same operator drives different wheeled excavator brands or when different operators drive the same wheeled excavator under similar working conditions. However, the impact of operator habits on fuel consumption is limited, as experienced operators tend to avoid unnecessary fuel consumption during operations.

  3. Effect of Wheeled Excavator Brand and Design:

    The design philosophy and professional competence of different wheeled excavator brands significantly impact fuel consumption. Factors such as the rational combination of hydraulic system components, mechanical control of the working device's stress points, and adjustments to design parameters for different working conditions contribute to variations in fuel consumption. The design intricacies and compatibility of components are vital factors overshadowing the role of engine displacement in determining fuel efficiency.

As the market becomes increasingly competitive, operators and customers are paying closer attention to real-world fuel consumption data. The influence of engine displacement, operator habits, and machine design are intricately linked, with design elements emerging as a primary factor affecting fuel consumption in wheeled excavators. Here are some fuel-saving tips for wheeled excavator users:

  1. Minimize Engine Idling:

    Avoid letting the wheeled excavator idle for extended periods during loading and unloading. Idling consumes fuel unnecessarily, and minimizing idle time contributes to fuel efficiency.

  2. Prevent Overloading:

    When faced with a load that one shovel cannot handle, it's advisable to use multiple shovels rather than overloading a single shovel. This practice prevents unnecessary fuel consumption and machine damage.

  3. Reduce Engine Speed:

    While maintaining operational efficiency, consider lowering the engine speed to significantly reduce fuel consumption. This adjustment applies both during work and travel, contributing to fuel efficiency without compromising performance.

  4. Limit Swing Angle:

    During loading and unloading, adjusting the machine position to reduce the swing angle shortens the working cycle, enhancing efficiency and fuel economy.

In conclusion, fuel consumption in wheeled excavators is influenced by a combination of engine parameters, operator practices, and machine design. By understanding and optimizing these factors, users can achieve better fuel efficiency and overall cost-effectiveness.
