  • Publication number: 20230243315
    Abstract: This disclosure generally relates to a method for oil mitigation in the cooling and lubrication of piston(s) for electronic fuel injected internal combustion engines, incorporating cylinder cutout technology. This concept leverages the engine fuel injection table and determines which cylinder(s) or bank of cylinders are to be cutout and specifically, reduces the pulse width of the fuel injected into those cylinder(s) to an idle condition, whereby reducing the reverse oiling and wet stacking effect, prevalent in traditional cylinder cutout technology.
    Type: Application

  • Patent number: 11421565
    Abstract: This disclosure generally relates to an oil mitigation system and method for lubricating the piston(s) for electronic fuel injected internal combustion engines, incorporating cylinder deactivation technology. This concept leverages the engine's base fuel injection pulse width table, determines the fuel injection “shutoff” state and, reduces the oiling to counter the reverse oil flow effect within the cylinder wall, past the ring set to the cylinder combustion chamber. This disclosure further comprises a system and method for mitigating oil consumption to all active cylinders, for accommodating all ranges of engine loading.
    Type: Grant

  • Publication number: 20150233279
    Abstract: A system and method of reducing soot and/or improving the efficiency of a motor. The system and method regulates the supply of cooling oil to a cooling section of a cylinder based upon observed parameters. These parameters can include such things as engine temperature, load, rpm etc. The control can be provided by using a look up table.
