MARTI Posted March 18, 2022 Report Share Posted March 18, 2022 Hi, I'm new in the forum. My ask is about the correct size of injectors, how is determined the continuous flow in cc/min? thank you!! Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 18, 2022 Report Share Posted March 18, 2022 You might have to elaborate on your question a little more as I dont understand what you are asking. Typically the injector flow rate is supplied in the data provided by the injector supplier. Usually it is determined dynamically using the linear slope of a graph of flow Vs pulsewidth at a specific frequency. Static "wide open" flow data is not as useful. Most flow test procedures are based around the SAE standard J1832 Quote Link to comment Share on other sites More sharing options...
MARTI Posted March 19, 2022 Author Report Share Posted March 19, 2022 Hi Adam!!! my question is about injector size selection before I start tuning. If I have an expected power, volumetric capacity of the engine and rpm at peak power, how do I determine the size I need? thanks!! Quote Link to comment Share on other sites More sharing options...
koracing Posted March 19, 2022 Report Share Posted March 19, 2022 The typical injector size calculation for a given amount of power is based on BSFC and several other factors. There are some basic rules of thumb, but you can also just use an online calculator like this: https://www.inchcalculator.com/fuel-injector-flow-rate-calculator/ Quote Link to comment Share on other sites More sharing options...
