"DIESEL ENGINE FUEL DISTRIBUTION SYSTEM; FUEL INJECTION FOR A FUEL DISTRIBUTION SYSTEM; " A fuel distribution system and a fuel injector are revealed. The fuel dispensing system includes a hole (18) that is formed in the engine head (10) and a fuel injector (21) is located in the hole (18). The hole (18) has an open end. The heating chamber (40) is defined between the fuel injector and the wall (18a) of the orifice (18). The injector has a fuel storage section that is located inside the heating chamber and during a compression stroke of the engine piston, gas in the engine combustion chamber is compressed and forced through the open end of the hole inside the chamber to heat the fuel storage section of the injector. In an alternative arrangement, the injector is provided with an enlarged end region (110) that fits within the engine bore and contacts the peripheral bore wall so that heat is conducted from the engine through the peripheral wall. orifice inside the enlarged injector section to heat the fuel within the injector end region.
