Direct injection engines are common to fuel injection systems in the construction machinery field.
Advantages of direct injection engine in oil supply mode, technical maturity and maintenance cost:
1. Oil supply mode :Direct injection engine: use mechanical linkage to control the injection time and quantity, pressure diesel oil through high pressure oil pump, and then use mechanical spray nozzle to atomize diesel oil. This method is simple and the technology is relatively mature, but the oil injection pressure is low, and the atomization effect is poor.
2. Technical maturity: Direct injection engine: after long-term market test, the technology is stable and reliable, especially in bad working conditions. Because of its simple working principle, low oil requirements, low maintenance cost.
3. Maintenance costs: Direct injection engine: Due to its relatively simple structure, daily maintenance and parts replacement are more convenient and low cost, it is suitable for users with limited budget.
4. Manipulability :Direct injection engine: by the manual direct control of the throttle opening degree, simple structure, easy to operate and master.
5. Oil product adaptability: Direct injection engine: low requirements for oil, can run stably under poor oil conditions, suitable for use in areas with uneven oil quality.
6. Energy-saving effect :Direct injection engine: Although the combustion efficiency is low, it can still provide a stable power output under some certain working conditions (such as heavy load operations).
Direct injection engine performs well under harsh working conditions and limited budget with its low maintenance cost and strong oil adaptability.
