However, sometimes this sensor can get clogged with particles or fail, so it'll supply the ECU with inaccurate information and causes the wrong air and fuel mixture. The Engine Control Unit (ECU) receives information from the sensor, then the ECU control the injectors to inject the right amount of fuel into the cylinders at the proper time. The Mass Air Flow (MAF) Sensor measures the air flowing into the engine's intake manifold. It simply takes approximately 10-90 mins with only an air intake cleaner, screwdrivers, wrenches, an OBD scanner, and anything else needed to gain access to the Mass Air Flow Sensor for your particular vehicle. IntroductionĬleaning the Mass Air Flow Sensor by yourself? Don't worry! This job doesn't require a professional.

To guide you on how to test and clean a Mass Air Flow Sensor. The intelligent signal processing of the deltaflowB, compares the redundant sensors and automatically recommends the recalibration, typically every 2 years.How To Test And Clean A Mass Air Flow Sensor (DIY) Purpose: Last but not least, thermal flow meters must be recalibrated up to four times a year, depending on the accuracy requirements. And the measurement is highly dynamic and does not need any With the deltaflowB, precise measurements are possible even with pulsations. Since pulsations in thermal flow meters lead to severe measurement errors, pulsation dampers (volumnia) must be inserted between the motor and the thermal sensor. This is good enough for all common upstream piping. The deltaflowB is supplied with a straight inflow section of around 10D. The deltaflowB has low requirements on the inlet conditions due to the venturi structure. In order to produce these, long inflow distances and flow straighteners are necessary, which negate the advantage of the low pressure losses of the thermal air mass sensors. First of all, as a result of the single-point measurement, the thermal sensors require ideal flow conditions. Thermal mass flow meters have a number of disadvantages compared to the deltaflowB. Advantages od deltaflowB compared to thermal mass flow meters Other outputs are optionally available via additional I/O cards. The connection to the test stand DCS is usually carried out via the second CAN interface of the PC.

The user-friendly software shows the operator both - the individual measured values of the three sensor locations as well as the filtered average values. The sensors are connected via a CAN interface on a master PC, which is doing the signal analysis. Highly disturbed inlet conditions will lead to a deviation between the three sensors. Since the triple measurement takes place at different locations in the venturi, the user is also informed about the flow conditions in the measuring device. Automatic maintenance and recalibration suggestions.Plausability check of the 3 x 3 measured values (p, dp, T).This redundancy has several advantages for the user: The deltaflowB is equipped with a triple sensor mount. The CAN-based sensors from systec Controls are measuring up to 2000 kb/s and are using highly developed filter strategies to separate pressure and flow pulsations and to calculate precise air mass flows. The result is errors depending on the pulsation strength and frequency (square root error). In addition to the slow transmission of measured values to the test bench, the main problem is that motor pulsations can’t be detected by standard sensors. Therefore at the highest flow rate, the pressure drop is still below 20mbar.Ĭommercially available pressure-, differential pressure- and temperature-sensors are by far too slow for the dynamics of engine test beds. This combination reduces the remaining pressure loss to less than 10% of the measured differential pressure.
