Can you drive without AdBlue?
Adblue is not physically required to run an engine, but running an engine without it will cause the vehicle emissions to exceed what's legally permitted, so the vehicles are programmed to refuse to start if it runs out. Some will restrict performance if the adblue runs low, again to reduce emissions.
What is an AdBlue injector?
AdBlue Injector: The AdBlue injector sprays the AdBlue solution into the exhaust stream, just before it enters the SCR catalyst. This ensures proper mixing for efficient NOx reduction. 4. AdBlue Tank and Level Sensor: The AdBlue tank is a separate compartment from the fuel tank.
