What is the difference between clean gas induction and regular EGR?

CGI or Clean Gas Induction is a technology found in some engines (stratified charge engines, ACERT-engine technology) to reduce harmful environmental emissions and enhance fuel efficiency. CGI is commonly found in engines that operate on diesel or gas.

An EGR valve is a technology responsible for making sure that the ignition system runs smoothly and effieciently, and a regular EGR valve cleaning can help to protect the valve and your internal combustion engine. It is essential to keep dust and solids away from the valves.
