my ford freestar is getting my manifold hot why
downstream from parent to subsidiary upstream from subsidiary to parent
Simply Upstream is the management of raw material, from logistics to storage and finally processing, and Downstream is the management of finished products from storage to outbound logistics, marketing and sales and finally customer service.
Generally upstream is closer to the positive (+) voltage source. In the case of an NPN transistor upstream of the transistor is the part of the circuit from (+) to the NPN collector pin. Downstream of the transistor is from the NPN emitter pin to the ground / sink / negative (-) terminal.
Upstream will be the closest to the engine, and are used to sense the air/fuel ratio and tell the computer how much fuel to inject. Downstream sensors are used to verify the upstream sensors and convertors are functioning correctly, so they are located after the convertors.
From what I understand , the oxygen sensor ( s ) upstream of the catalytic converter is used in the control of the air / fuel ratio . The oxygen sensor downstream of the catalytic converter is called a catalyst monitor and monitors the efficiency of the catalytic converter
The upstream of a river is its mouth, AKA, the opening to the ocean, and everything in between. Downstream is the source, AKA the "beginning", such as a lake, and everything in between.To put it simply:A RIVER:(Mouth)=--------------------------------------------------------------------------------0 (Lake) Downstream
In the food processing industry, upstream involves farming of raw material such as fruits, vegetables, livestock rearing, grain, etc.The downstream stage in the production process involves processing the materials collected during the upstream stage into a finished product. The downstream stage further includes the actual sale of that product to other businesses, governments or private individuals.
ADSL is simply a version or 'flavour' of DSL. The 'a' refers to asymmetric, meaning 'not the same'. Hence, ADSL usually has different downstream and upstream rates (e.g. 1536/256 is a common speed of ADSL available in Australia, where downstream the link speed is 1536kbps and upstream is 256kbps).
It depends on the make and model of your car. Sometimes the wires of the downstream sensor need to be longer than the upstream sensor. This would mandate a different part number. Sometimes the upstream sensor is a "wideband" or "universal" type O2 sensor, as opposed to a "switching" type O2 sensor (which is always found in the downstream position). This would also mandate a different part number.
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
Sensor 1 would be before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
