Injector Adaptor , fuel injector and fuel components

Calculating fuel injector size involves several factors, including the engine’s horsepower, fuel pressure, and the number of injectors. The most common formula used for this calculation is based on brake-specific fuel consumption (BSFC), which is the amount of fuel required to produce one horsepower for one hour. Here’s a basic formula to calculate fuel injector size:

• Injector Size is the flow rate of the fuel injector in pounds per hour (lb/hr).
• Horsepower is the engine’s estimated or measured horsepower.
• BSFC is the brake specific fuel consumption, typically given in lb/hp/hr. You can find average BSFC values for different types of engines, with turbocharged engines generally having higher values than naturally aspirated engines.
• Number of Injectors is the total number of injectors you plan to use.
• Injector Duty Cycle is the percentage of time the injector is open during each engine cycle. A common value is around 80%.
