With the continuous increase in the number of wheel excavator models in the domestic market, the topic of wheel excavators is also heating up. Both demand customers and users are increasingly concerned about the details of wheel excavators, as these are crucial for competitive advantages and sustained earnings in the real market. Among these, the fuel consumption of wheel excavators is a common and unavoidable substantive issue. Especially in the domestic market dominated by wheel excavators around 8 tons, what are the key factors determining fuel consumption?

Impact of Engine Displacement

For wheel excavator models around 8 tons, the displacement of the diesel engines used is generally around 2000ml, even though there may be slight variations among different brands.

However, due to the limitations of wheel excavator models, power output, and operational field interference, parameters like displacement and horsepower still need to adhere to the objective environmental requirements.

It is evident that engine displacement is not the dominant factor affecting the fuel consumption of similar wheel excavator models. Construction machinery, unlike transportation tools, has its fuel consumption linked to the engine, but this link is overshadowed and obscured by many more significant interference factors. Moreover, many wheel excavators use domestically produced diesel engines or those branded as imports but assembled domestically, showing minimal difference in fuel consumption performance and breakthroughs.

Interference of Operating Habits and Conditions

In some more mature wheel excavator markets, experienced operators have started to analyze sets of practical data. This is not time-wasting or creating unnecessary work, but rather because fuel consumption has become a key factor affecting actual earnings in the fierce market competition.

What conclusions can be drawn from the same operators driving different brands of wheel excavators, or different operators driving the same wheel excavator, under the same working conditions?

Under similar working conditions and with operators of similar experience, the impact of operating habits on the fuel consumption of wheel excavators is quite limited. After all, as experienced operators of wheel excavators, they know how to drive economically. In actual work, many avoid unnecessary fuel wastage.

Influence of the Wheel Excavator Brand Model’s Own Design

This aspect always gives an abstract macro concept and seems unable to be debated in detail. However, in the diverse domestic market, different brands of wheel excavators have significant differences in their design concepts and professionalism for wheel excavator models.

We can easily distinguish them based on the manifestation of fuel consumption. This includes the rationality of the organic combination of components in the hydraulic system, mechanical control of the stress points on the wheel excavator operating device, and changes (or lack thereof) in the design parameters of the wheel excavator under different working conditions...

The power distribution and energy output ratio of wheel excavator work is based on effective and reasonable connections in each minute detail. It is not about assembling without considering the compatibility of the components. This ultimately leads to significant differences in fuel consumption for the same tonnage models of different wheel excavator brands.
