摘要：
A method for controlling combustion timing in an homogenous-charge compression-ignition engine, comprising:
providing a fuel conduit extending between a source of a parent fuel and at least one fuel introduction port in fluid communication with a combustion chamber of said engine and having a flow-through portion and a by-pass portion said by-pass portion having a means incorporated therein adapted to alter the reactivity of the parent fuel passing through the by-pass portion of the fuel conduit;
providing a means for controlling the relative amounts of fuel passing through the flow-through and the by-pass portions of the fuel conduit;
sensing at least one engine operating parameter; and
controlling the relative amounts of fuel passing through the flow-through portion and the by-pass portion of the fuel conduit in response to a sensed value of said at least one engine operating parameter.
