Injector-igniter with fuel characterization
View Patent ↗A vehicular fuel system with onboard fuel characterization including an onboard combustion modifier source capable of supplying a combustion modifier agent, such as hydrogen, and a fuel tank capable of storing a fuel. An injector-igniter is operative to direct inject the fuel and a proportionate amount of the modifier agent into a cylinder of an internal combustion engine. An engine control unit is operatively connectable to the combustion modifier source and the injector. The system may further comprise a mixing valve operative to proportionately mix the fuel and modifier agent. The combustion modifier source may be a tank containing hydrogen or a thermo-chemical reactor, for example.
1. A fuel system with fuel characterization comprising:
a hydrogen generator capable of supplying hydrogen as a combustion modifier agent, the hydrogen generator comprising:
an annular steam distributor;
a set of traction rollers operative to feed a wire feed stock into the annular steam distributor; and
heater positioned to assist rapid initial production of hydrogen;
a fuel tank to store a fuel;
an injector-igniter operatively connected to the fuel tank and the hydrogen generator to direct inject the fuel and a proportionate amount of the combustion modifier agent into a cylinder of an internal combustion engine; and
an engine control unit operatively connectable to the hydrogen generator and the injector.
2. The fuel system according to claim 1 , further comprising a mixing valve operative to proportionately mix the fuel and the combustion modifier agent.
3. The fuel system according to claim 1 , wherein the injector-igniter comprises a first channel configured to inject the modifier agent.
4. The fuel system according to claim 3 , wherein the injector-igniter comprises a second channel configured to inject the fuel, wherein the second channel is separate from the first channel.
5. The fuel system according to claim 1 , further comprising a set of distressing rollers operative to perforate the feed stock.
6. The fuel system according to claim 1 , further comprising a water supply in fluid communication with the annular steam distributor.
