First Claim
Patent Images
1. An injector-ignition fuel injector for dispensing fuel into a combustion chamber of an internal combustion engine, the fuel injector comprising:
- an input fuel metering system for dispensing a fuel charge into a pressurizing chamber;
a pressurization ram system including a pressurization ram for compressing the fuel charge within the pressurizing chamber, wherein the fuel charge is heated in the pressurization chamber in the presence of a catalyst; and
an injector nozzle for injecting the heated catalyzed fuel charge into the combustion chamber of the internal combustion engine wherein the fuel injector dispenses the fuel charge substantially exclusively during a power stroke of the internal combustion engine.
