What is the relation between sfc vs rpm in diesel engine and why does it happen like that ? what is relation between air flow vs rpm ??

SFC (Specific Fuel Consumption) refers to the amount of fuel consumed per unit of power output in a diesel engine. It is typically measured in grams per kilowatt-hour (g/kWh). RPM (Revolutions Per Minute) is the rotational speed of the engine's crankshaft, which is measured in revolutions per minute.
SFC and RPM have an inverse relationship in a diesel engine. This means that as the engine's RPM increases, the SFC decreases and vice versa. This is because at higher RPM, the engine is producing more power with the same amount of fuel, resulting in a lower SFC.
Understanding the SFC vs RPM relationship is important for optimizing the performance and efficiency of a diesel engine. By adjusting the RPM and monitoring the SFC, engineers can determine the most efficient operating point for the engine, resulting in improved fuel economy and reduced emissions.
The SFC vs RPM relationship can be affected by factors such as the engine load and size. Generally, a higher engine load (more power output) will result in a lower SFC at a given RPM. Similarly, a larger engine with a larger displacement will have a lower SFC compared to a smaller engine at the same RPM.
While the SFC vs RPM relationship is generally true, there are some limitations to keep in mind. For example, at very low RPM, the engine may not be producing enough power to effectively burn the fuel, resulting in a higher SFC. Additionally, other factors such as engine design, fuel quality, and operating conditions can also impact the SFC vs RPM relationship.
