ABSTRACT:
A fuel and air assembly is provided for furnishing an air and fuel mixture under pressure to a cylinder of an ignition fired internal combustion engine which utilized a solenoid-actuated valve timed to admit the mixture to the cylinder. A standard fuel injector is interfaced with one end of a mixing insert which is connected at the other end to an air passage of a fuel rail. At one side of the insert is an outlet passage leading to the solenoid actuated valve which has an outlet end shaped to enhance fuel distribution and combustion. The mixing insert contains an air filter and passages to conduct air to the common passage for air and fuel. The insert is captured in the fuel rail between a locating shoulder and the fuel injector for proper positioning relative to the timed valve. An adapter cap on the solenoid assembly joins the insert to the valve controlled passage to the cylinder.
