1.Product Introdcution

HEUI (Hydraulic Electronic Unit Injector), EUI (Electronic Unit Injector), and EUP (Electronic Unit Pump) are all fuel injection technologies used in diesel engines. These systems are critical for ensuring precise fuel delivery, which improves engine efficiency and reduces emissions. Here’s a brief overview of each:

  1. HEUI (Hydraulic Electronic Unit Injector):
    • Working Principle: HEUI uses high-pressure engine oil to hydraulically actuate the injector. Electronic controls manage the timing and duration of the fuel injection.
    • Advantages: Provides precise control over fuel delivery, allowing for better combustion efficiency and reduced emissions.
    • Applications: Commonly used in heavy-duty diesel engines, such as those found in trucks, buses, and construction equipment.
  2. EUI (Electronic Unit Injector):
    • Working Principle: EUI integrates the injector and high-pressure pump into a single unit. The injector is controlled electronically, and the high-pressure pump is driven by the engine’s camshaft.
    • Advantages: Combines the functions of fuel injection and high-pressure pumping, allowing for precise fuel metering and timing.
    • Applications: Widely used in both light-duty and heavy-duty diesel engines, including those in commercial vehicles and some passenger cars.
  3. EUP (Electronic Unit Pump):
    • Working Principle: EUP separates the high-pressure pump and injector into different units. The pump is driven by the engine’s camshaft, while the injector is controlled electronically.
    • Advantages: Allows for high injection pressures and precise control of the injection process, improving fuel atomization and combustion efficiency.
    • Applications: Often found in large industrial and marine diesel engines.
