Abstract
Technical solutions are described for measuring fuel injection to an engine of a vehicle. For example, an engine control unit (ECU) that controls the operation of the engine, is equipped with a first direct memory address channel to store rail pressure values that are received from the engine in a first buffer. The ECU further includes a second direct memory address channel configured to copy a first subset of the rail pressure value from the first buffer to a filter module in response to an angle-based interrupt request. The ECU further includes a third direct memory address channel configured to copy filtered pressure values from the filter module to a second buffer. The ECU also includes a processor that computes a pressure drop based on the filtered pressure values from the second buffer, and compute a quantity of fuel injected into the engine based on the pressure drop.
