Abstract
A piston for an internal combustion engine which includes a crown having spiral features designed to increase swirl of combustion gases in a cylinder of the engine is provided. The spiral features can be located in a combustion surface or in a combustion bowl of the crown. The increased swirl of the combustion gases is expected to improve mixing of the air and fuel injected into the cylinder, and thus cause the fuel to burn more completely, achieve better efficiency out of the injected fuel, and reduce unburned hydrocarbons in the exhaust gas.
