摘要： A digital signal obtained by A/D converting an output of a thermal type air flow meter is supplied along two paths. After a time constant is obtained in one path, inverse-transformation is performed to obtain an error together with an output of the other path. The inverse-transformed signal is linearized on the basis of the characteristic of the thermal type air flow meter, and a direction of flow is determined.

摘要： A hot-wire air flow meter for detecting air flow intake has a main passage (21) and a generally parallel sub-passage (31) for bypassing said main passage, and located in the sub-passage is a hot-wire element (2a) for detecting air flow intake. A dished member (34) is located upstream from an inlet (31a) of the sub-passage, the dished member having a base portion adjacent the sub-passage inlet and an upstream projecting edge (30a) extending from said base portion. The upstream extending edge (30a) at least partially surrounds the inlet (31a) and is located between the sub-passage inlet and the main passage, the effect of the dished member tending to stabilize air flow entering the sub-passage so that the air flow is less affected by bends in pipework upstream from the air flow meter.

摘要： In a flow sensor, detecting elements are provided at a sub-passage. A sub-passage wall contains a hole to drain accumulated liquid. A protrusion arranged close to the hole on an external surface generates dynamic pressure on the opening in response to external flow. Alternatively, a protrusion upstream from the hole on the inner wall surface produces a separation flow area for separating the flow from the internal surface near the hole, whereby pressure in the separation area is reduced and almost the same pressure differences on the internal and external surfaces openings result. This reduces leakage from the hole and changes in the distribution flow in the sub-passage between cases where the hole is blocked and not blocked, thus minimizing flow measurement errors. Structure may be provided close to the external surface hole opening to prevent a liquid film or drop from being formed on the opening by surface tension.

摘要： In an engine having a premixed combustion mode, an EGR flow rate estimating precision is deteriorated at a transient time, and a torque fluctuation and an exhaust gas deterioration are caused. In an engine control apparatus having a premixed combustion mode and a diffusion combustion mode, a sensor detecting an EGR flow rate is arranged in an EGR flow path of the engine, and a cylinder state of the engine is estimated by using an output value of the sensor detecting the EGR flow rate at a time when the engine is in the premixed combustion mode. Since it is possible to accurately detect the EGR flow rate at the transient time and feed back the EGR flow rate at a high response, it is possible to prevent a torque fluctuation and an exhaust gas deterioration.

摘要： To realize a control apparatus for an internal combustion engine having a heating resistor type air flow rate measuring apparatus which can effectively remove salinity adhered to the heating resistor. Salt adheres not only to the heating portion of a heating resistor but also to lead members and supporting members. When a certain time period is passed after the current supply to the heating resistor is stopped, the salt adhered thereto absorbs moisture in the air by deliquescence, and becomes salt water near the heating resistor and the support members etc. Then, suction air flows through an auxiliary air passage by the cranking of the engine to disperse the salt water adhered not only to the support member parts but also to the heating resistor. Thus, even if the heating resistor is supplied with current after the dissipation, salt components do not remain on the heating resistor.

摘要： In a thermal-type airflow meter that measures an intake airflow rate in an internal combustion engine of an automobile or the like, there has been a problem that pulsation errors caused by external fluctuations under the environment including a large pulsation and reverse flow in the intake valve are difficult to be reduced. In order to solve this problem, the invention provides a flowmeter comprising a detection element that outputs a non-linear signal corresponding to a flow rate, and a regulation means that regulates an output signal of the detection element for controlling. With this construction, the regulation means executes output regulation processing that regulates irregularities of the detection element in the output signal, and inequality linearization processing that regulates an average value of the output signal after the output regulation processing by means of regulating parameters.
