Injector-igniter with fuel characterization

摘要

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 thermo-chemical regenerative reactor comprising,
a reactor vessel positioned within an exhaust manifold and having an inlet for receiving fuel reactants to be preheated by exhaust gases within the exhaust manifold, anda fluid network extending through the reactor vessel having fluid flow, wherein a combustion modifier agent is produced in the fluid network via heating provided by an inductive heater element positioned within the fluid network; a fuel tank to store a fuel; and an injector operatively connected to the fuel tank and the fluid network of the thermo-chemical regenerative reactor to inject the fuel and a proportionate amount of the combustion modifier agent into a cylinder of an internal combustion engine; wherein the injector includes a first channel configured to inject the modifier agent and a second channel configured to inject the fuel, wherein the second channel is separate from the first channel.
