How do Entry Ignition (EI) engines overcome the biggest flaws of combustion engines? We know that Spark Ignition (SI) engines are inefficient, we know that Compression Ignition (CI) engines have bad emissions, and we know that Homogeneous Charge Compression Ignition (HCCI) engines are very difficult to control. The closest thing we have today are prototype engines using Mazda's Spark Controlled Compression Ignition (SPCCI), but even they still use spark plugs for transient engine conditions, and use spark plugs to initiate compression ignition. Entry Ignition is an all-new method of combustion that seeks to solve the problems of other combustion methods. How does it work? Watch the video to learn all about it!
