摘要： A: piezoelectric fuel injector spring assembly and an assembly method for assembling such a piezoelectric fuel injector spring assembly. The assembly has a piezoelectric element (204}, a first spring {212), and a second spring (210). The first spring (212) biases the second spring (210) by expanding the second spring {210}, and the second spring {210} is further expanded when the piezoelectric element (204) expands. For the assembly, the first spring is compressed by an external compressing force prior to connecting a second end of the second spring to a second end of the piezoelectric element, and after connecting the external force is released allowing establishment of spring force equilibrium between the first and second spring.

摘要： The present invention provides an injector-ignition fuel injection system for an internal combustion engine, comprising an ECU controlling a heated catalyzed fuel injector for heating and catalyzing a next fuel charge, wherein the ECU uses a one firing cycle look-ahead algorithm for controlling fuel injection. The ECU may further incorporate a look-up table, auto- tuning functions and heuristics to compensate for the rapid rotational de-acceleration that occurs near top dead center in lightweight small ultra-high compression engines as may be used with this invention. The ECU may further ramp heat input to the injector in response to engine acceleration requests and, under such circumstances, may extend its look-ahead for up to four firing cycles.

摘要： The present invention provides a heated catalyzed fuel injector that dispenses fuel substantially exclusively during the power stroke of an internal combustion engine, wherein ignition occurs in a fast burn zone at high fuel density such that a leading surface of the fuel is completely burned within several microseconds. In operation, the fuel injector precisely meters instantly igniting fuel at a predetermined crank angle for optimal power stroke production. Specifically, the fuel is metered into the fuel injector, such that the fuel injector heats, vaporizes, compresses and mildly oxidizes the fuel, and then dispenses the fuel as a relatively low pressure gas column into a combustion chamber of the engine.

摘要： A fuel injection method in an internal combustion engine and an internal combustion engine for performing the fuel injection method. The method includes heating fuel to a temperature between 300°F and 840 °F (150 and 450°C); pressurizing the fuel to a pressure exceeding 40 bar; pre-injecting at least 10% of the fuel charge as a pre-injected fuel during the intake stroke; injecting a fuel charge over at least part of the compression stroke into the cylinder; and injecting an ignition-injection of at least 10% of the fuel in a supercritical condition during the compression stroke at a rotational angle between 90° BTDCF and TDCF into the cylinder. The method and related combustion engine create a good mix of premix combustion and diffusion combustion increasing efficiency and consequently reducing emissions to the environment while also keeping noise and vibrations low.

摘要： A fuel system for an automotive engine is provided that includes a catalytic reactor that is configured to partially oxidize a portion of hydrocarbons in a hydrocarbon based fuel to create a fuel that is more compression ignitable. Exhaust gas is diverted from the exhaust system of an automobile and mixed with a hydrocarbon fuel. The fuel/exhaust gas mixture is exposed to an oxidizing catalyst such that at least a portion of the hydrocarbon fuel is partially oxidized. The resultant fuel mixture is metered into a compression ignition engine for engine operation.
