摘要： An apparatus and method for adjusting a throttle plate of a throttle assembly of an internal combustion engine is disclosed. A throttle linkage mechanically connects a throttle actuator to the throttle assembly with a deadband therebetween. The deadband allows the throttle plate to remain in a closed position during initial movement of the throttle actuator and initial acceleration, thereby reducing overall engine noise.

摘要： The present invention, in one aspect, includes a diaphragm assembly for being connected between an engine exhaust path and an engine electronic control unit to transmit changes in exhaust gas pressure from the exhaust path to the control unit. In an exemplary embodiment, the diaphragm assembly includes a diaphragm housing and a diaphragm positioned in the housing and separating a first chamber and a second chamber. The first chamber is configured to be in flow communication with the exhaust path and the second chamber is configured to be in flow communication with the engine control unit. The diaphragm housing, in the exemplary embodiment, includes a first housing member and a second housing member. An inner surface of the first housing member also is a side wall of the first chamber, and the inner surface has a conical shape to facilitate drainage of water from the first chamber. Also, the first chamber has a first volume and said second chamber has a second volume. The first volume is greater than the second volume. The diaphragm includes an o-ring and a diaphragm member integral with the o-ring. In the exemplary embodiment, the o-ring and said diaphragm member are fabricated from fluorosilicone. The first and second housing members each include an o-ring groove so that when the housing members are assembled, the diaphragm o-ring is trapped between the first and second housing members in the grooves.

摘要： State-of-the-art fuel injectors can be defined by a third-order polynomial to define their performance curve and to optimize performance of the fuel injected engine. Such systems are preprogrammed to use a set of fixed coefficients when replacing fuel injectors. Therefore, these replacement fuel injectors must be manufactured with very precise tolerances so as to operate efficiently with these fixed coefficients. The present invention includes a method and apparatus that allows the use of production fuel injectors that are more economical since they can be manufactured with wider tolerances. The production fuel injectors are supplied with a computer program and a data file having a set of replacement coefficients that are determined especially for that particular fuel injector. The approach allows the restoration of the existing coefficients if the replacement fuel injector does not solve the service problem experienced by the user of the fuel injected engine. The new, replacement fuel injector, together with its specific coefficients, can then be used in another application.
摘要翻译：最先进的燃料喷射器可以通过三阶多项式定义，以定义其性能曲线并优化燃油喷射发动机的性能。当更换燃料喷射器时，这种系统被预编程为使用一组固定系数。因此，这些更换燃料喷射器必须以非常精确的公差制造，以便以这些固定系数有效地运行。本发明包括一种方法和装置，其允许使用更加经济的生产燃料喷射器，因为它们可以制造具有更宽的公差。生产燃料喷射器被提供有计算机程序和数据文件，该数据文件具有特定于特定燃料喷射器确定的一组替换系数。如果更换燃料喷射器不能解决燃油喷射发动机的使用者遇到的使用问题，该方法允许恢复现有系数。新的替代燃料喷射器及其特定系数可以在另一应用中使用。

摘要： A control unit is provided for an internal combustion engine including an engine block comprising a plurality of cylinders operable in a homogenous combustion mode and a stratified combustion mode in response to an engine throttle position. The control unit is programmed to switch the engine cylinders to the homogenous combustion mode at a throttle position of greater than about 20% of wide open throttle. As such, the combustion mode is switched form the stratified combustion mode to the homogenous combustion mode at a higher throttle opening that more capably supports increased fuel injection quantities of homogenous combustion in the engine cylinders. Problematic conditions of conventional pontoon boat systems due to switching of engine cylinders to homogenous combustion at high RPMs and restricted throttle openings is therefore avoided.
摘要翻译：提供一种用于内燃机的控制单元，其包括发动机缸体，该发动机缸体包括响应于发动机节气门位置以同质燃烧模式和分层燃烧模式操作的多个气缸。控制单元被编程为在大于敞开节气门的约20％的节气门位置处将发动机气缸切换到均匀燃烧模式。这样，燃烧模式从分层燃烧模式切换到均匀燃烧模式，在较高的节气门开度，更可靠地支持增加发动机气缸中均匀燃烧的燃料喷射量。因此，避免了由于将发动机气缸切换到高RPM和限制节流开口处的均匀燃烧而导致的常规浮筒系统的问题。

In an exemplary embodiment, the probe includes an elongate probe body and an engine engagement assembly secured to the probe body and configured to engage to the engine so that said probe body at least partially extends into the engine exhaust path. The probe body comprises a hollow, cylindrical shaped member, and at least one opening extends through a side wall of the cylindrical shaped member. A cap is secured to and closes an open end of the probe cylindrical shaped member, and a pellet is located, i.e., trapped, within the cylindrical shaped member. The engine engagement assembly includes a threaded portion sized to be threadedly engaged within an opening in flow communication with the engine exhaust path, and a tube connection portion sized to be inserted within a tube.
