General Motors Corp. today unveiled a new engine it that it says will increase fuel economy by 15 percent by burning gasoline the same way a diesel engine burns fuel. GM calls the innovation ...

The differences between gasoline and diesel engines lie not only in their fuels, but in how those fuels are ignited. Gasoline engines use spark plugs, while diesels simply use compression. But it is ...

Not all gasoline engines need spark plugs to ignite their fuel. A process called homogeneous-charge compression ignition (HCCI) uses compression to ignite the fuel, just like in a diesel engine.

Earlier this month, Japanese automaker Mazda laid out its future powertrain strategy and dropped a massive announcement in the process. In 2019, Mazda will introduce a gasoline-powered Homogeneous ...
