Performance - related Specifications
Injection Pressure Compatibility
The nozzle is engineered to operate under high - pressure conditions typical of common - rail fuel injection systems. It can handle injection pressures ranging from a minimum of [Min_Pressure] bar to a maximum of [Max_Pressure] bar. This wide pressure range enables efficient fuel atomization, which is vital for complete combustion in the engine cylinders.
Fuel Spray Characteristics
Spray Angle: The nozzle is designed to produce a spray angle of [Spray_Angle] degrees. This specific angle ensures that the fuel is evenly distributed within the combustion chamber, promoting better mixing with air and enhancing combustion efficiency.
Droplet Size Distribution: It generates a well - defined droplet size distribution. The majority of fuel droplets have a diameter in the range of [Droplet_Size_Range] microns. Smaller and uniformly sized droplets contribute to more rapid and complete combustion, reducing emissions and improving engine power output.
Flow Rate Precision
The nozzle has a highly precise flow rate. At a standard test pressure of [Test_Pressure] bar, the flow rate is [Flow_Rate] cubic centimeters per minute. This consistent flow rate is crucial for maintaining the correct fuel - to - air ratio across different engine operating conditions in the CAT 3114 and 3116 engines.
