  • Fuel distribution arrangement for an internal combustion engine
    Patent number: 5803051
    Abstract: To provide a uniform temperature level for fuel supplied to individual cylinders of an internal combustion engine, a fuel-carrying passage is formed in a cylinder head and an insert formed with outflow orifices and supports extending along its outer surface is mounted in the passage. Because the insert acts as a countercurrent heat exchanger, and as a result of intermixing of fuel streams emerging through the outflow orifices, a uniform temperature of the fuel supplied through transverse lines to the fuel injectors is obtained.
