Hi Jeff, black smoke coming out of your exhaust when you accelerate is a sign of incomplete combustion. This could be caused by a clogged air filter as it can restrict airflow to the engine, causing it to run rich and produce black smoke. Replacing the air filter is a inexpensive.

The EGR valve recirculates a small amount of exhaust gas back into the intake manifold.This helps reduce combustion. A faulty EGR valve can cause black smoke by allowing too much unburnt fuel into the exhaust. Faulty fuel injectors can deliver too much fuel or create an uneven spray pattern. This can also lead to incomplete combustion and black smoke.

 If your RAV4 has a turbocharger, problems with it can cause black smoke. A leaking turbo seal can allow oil to enter the intake system, which will burn and create black smoke. If you are unable to check these items yourself then it would be better to ask a mechanic or book it into a Toyota dealer. Hope this helps.
