What's wrong with the intake manifold pressure sensor?
The most obvious is the intake volume is not allowed, mixed gas imbalance, fuel consumption increases, the exhaust pipe black, power down.
Hello: in order to provide the correct injection rate of the injector, the intake volume should be fed back to ECM by the pressurized intake manifold pressure sensor. The assembly position is usually at the top of the intake manifold. The ECM calculates the actual amount of air (actual intake) that actually enters the engine to participate in the combustion, depending on the state of the other relevant parameters of the engine. ECM according to the principle of fluid mechanics, according to the intake manifold air temperature and pressure of the actual test data and considering the influence factors of other related parameters according to the air intake in the engine provides the ideal proportion of fuel injection quantity.
According to the load state of the engine, the change of the vacuum degree in the intake manifold is measured and converted into a voltage signal, which is transmitted to the ECU along with the speed signal as the basis of the basic injection amount of the injector.The pressure sensor is one of the most commonly used sensor in industrial practice, which is widely used in various industrial control environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electric power, shipbuilding, machine tools, plumbing and other industries, following a brief introduction of some commonly used sensor principle and its application. Another medical pressure sensor.
