It does not have secondary air injection.
It injects/blows air into your exhaust near or in the cylinder head's exhaust port. It also injects air into the catalytic converter. This is done to give the unburnt hydrocarbons in the exhaust gases some oxygen to continue burning in the exhaust system/catalytic converter in order to reduce emissions.
what causes air injection system pressure to be stucked in cars
Because - depending on what's in the reactor (you didn't say what type) - elements present in air could react with the contents. Argon - on the other hand - is non-reactive in most circumstances.
Fuel injection gives the best air to fuel ratio for best performance and efficiency.
I belive It is an air pump I would recommend that you leave it there because it helps the engin breath better. it is an air pump and in some states it HAS to be in working order to pass emissions at inspections. It is the A. I. R. (air injection reactor) pump they put them on for emissions. I would recommend keeping it on to pass emissions testing
Yes, the smog pump is correctly called an air injection pump. It pumps air into the exhaust when forst started to help the cat warm up.
There are several ways to fix the secondary air injection system in a 2005 Chevrolet trailblazer. The most common fix is; changing the air filter.
to avoid loss of drug as , after complete injection the air bubble remain inside the needle, not the drug
Air intake plenum.
Bleeding injection pumps insures that no air is trapped in the lines. Injection pumps supply fuel at pressure into the cylinders of intermal combustion engines, and if any air is present in these systems, it will inhibit the ability of the pump to deliver the correct amount of fuel. (We know that air can be compressed, and fuel is largely incompressible.) Additionally, air can be trapped at a number of places in a fuel injection system, and this may make it difficult for someone attempting to discover why an engine is running poorly to get to the bottom of things. Bleeding injection pumps insures that the pump will not incorrectly operate because of air in the pump.
No, it is not true.
