New HCCI Engine Design Improves Fuel Economy

The New-Technology HCCI Engine

The internal combustion engine powering today’s cars and trucks has stayed pretty much the same during the hundred years or so since its invention. Engineers have tried for decades to improve the engine’s efficiency, without running up significant cost increases. The homogeneous charge compression ignition (HCCI) engine design does exactly that.

It runs more efficiently and produces fewer toxic emissions. It does this by burning the fuel through a flameless combustion process that isn’t triggered by a spark plug. This is valuable even for hybrid vehicles, since they’re generally still using an internal combustion, gasoline powered engine.

By replacing the internal combustion engine with an HCCI engine, fuel efficiency can be improved by more than fifteen percent. GM is already looking at putting this engine design into production in its future releases.
