The fuel injection system, in particular the nozzle lift or timing, is optimally designed to maximize fuel economy and reduce emissions. This means that the injection process begins before the intake manifold pressure has reached its peak. This means that the fuel injection process is governed by the peak intake pressure and not the running intake pressure. The intake pressure is measured by the intake manifold pressure sensor and has a maximum value that is defined by the engine designer. The running intake pressure is the variable that is measured by the air flow sensor and that is used by the engine control unit to determine the timing for the fuel injection process.

On the other hand, the fuel injection process cannot be properly controlled if the intake pressure is too low. In most engines, a high base speed is required so that the engine can build high torque at low speed. This base speed is in turn governed by the air flow delivered through the throttle (ABS system). The fuel injection process is controlled by a target air flow. In most vehicles, the maximum air flow is reached when the accelerator pedal is being pressed to its full-throttle position. This maximum air flow is generated by the engine designer and has a maximum value. The target air flow is calculated so that the maximum air flow value is equal to the maximum air flow value (maximum air flow) to be achieved and that the air flow is increasing. The actual air flow delivered to the engine by the throttle is lower than the target air flow because of the throttle body and the air flow losses that occur in the air duct. This throttle back will increase the intake pressure of the engine and therefore will decrease the amount of fuel that is injected. This implies that the actual air flow value will be below the target air flow value.

In measurement fuel injection systems, the tendency to estimate the injection pump stroke and determine the number of pulses is a very important issue. In fact, the time between the beginning of the current shot and the end of the previous shot is called the lag. How to simulate the injection pump lag in Simucal3D?
Fuel mass is the amount of fuel injected into the engine cylinders during the entire calibration period. Temperature and atmospheric pressure are also considered as fuel mass components. In order to compute the fuel mass, the fuel mass components and the fuel mass temperature (TL) at the injection pump are required. In our case, the fuel pump strokes are recorded throughout the calibration period and combined with TL to compute the fuel mass. The fuel mass of the calibration period depends on many factors. For example, it depends on the calibrated boost pressure, the total pump strokes, the pump efficiency (percentage) and water temperature.
When installing a fuel injection pump, it is important to remove the injection pump’s full bore and/or extra injection sleeve. This is done to ensure optimal flow rates when fuel enters the injection pump. Failure to do so could lead to poor fuel delivery which, in turn, could lead to excessive engine emissions. The injection pump’s full bore diameter (number of strokes) is specified on the pump’s label.
When estimating the fuel consumption, the response of the engine to the fuel injection is considered. For example, the fuel injection valves, the injector needle and the shaft of the fuel pump are assumed to be elastic. If there is a constant offset from the reference point, the fuel consumption will be affected. The effects of the elasticity of the valves and needle on the fuel consumption is discussed in detail in the calibration energy consumption tutorial.
