Has the excavator with direct injection engine been phased out? Of course, not now that electronic fuel injection has become mainstream or even domestically, and there are specific requirements for excavators to use electronic fuel injection engines that meet the requirements within a certain range. There are many considerations here, and electronic fuel injection undoubtedly leads direct injection engines in terms of fuel consumption and emissions. But this is not the key, but the impact of high pollution has gradually made the country pay attention to the pollution caused by construction machinery. What is emphasized here is not only for the construction machinery excavator industry, but also for all enterprises and industry standards with pollution situations that must be followed today and in the future.
So, can't we buy direct injection? This is not absolute. Excavators with direct injection power systems are still very active in major engineering projects in China. Even now, some manufacturers in China still use direct injection engines for their new models, especially for small equipment. Electronic injection not only controls costs but also has minimal impact on small displacement engines. The technology of electronic fuel injection is becoming increasingly mature, and the technology of direct injection engines is also being upgraded. If you consider purchasing electronic fuel injection in remote areas, you must think about which models of equipment are more abundant and which types of power systems are more widespread in the local area. The first consideration is whether the maintenance situation in the later stage can keep up. If a purchased electronic fuel injection excavator experiences malfunctions and cannot even find a technician to purchase spare parts in the later stages of maintenance, wouldn't it be worth the loss. The vast majority of cities in China do not have requirements for excavator engines, so direct injection is still very important for customers considering buying small excavators in the short term. For medium or large excavator equipment, the advantages of electronic fuel injection are very obvious. If such equipment is needed in the construction site, the surrounding supporting facilities will inevitably be more mature. So when purchasing this type of excavator equipment, there is no need to consider so much, and the fuel consumption and efficiency of the same model of electronic injection machine are very high.
In the future, it can be said that in the coming years, the country will require regulations for equipment that causes heavy pollution and emissions. If there are old and severely damaged equipment on handexcavating machineryHuacheng suggests that the equipment be dealt with as soon as possible. After the policy is introduced, it can only be idle and scrapped.
