  • Patent number: 11959436
    Abstract: A piston for an internal combustion engine which includes a crown having spiral features designed to increase swirl of combustion gases in a cylinder of the engine is provided. The spiral features can be located in a combustion surface or in a combustion bowl of the crown. The increased swirl of the combustion gases is expected to improve mixing of the air and fuel injected into the cylinder, and thus cause the fuel to burn more completely, achieve better efficiency out of the injected fuel, and reduce unburned hydrocarbons in the exhaust gas.

  • Patent number: 11952937
    Abstract: A two-stroke engine possesses a cylinder, in the cylinder bore of which a combustion chamber is formed. The combustion chamber is bounded by a reciprocating piston, which drives a crankshaft rotatably mounted in a crankcase. A crankcase interior is fluidically connected to the combustion chamber across at least one transfer channel in at least one position of the piston. The at least one transfer channel emerges with a discharge opening in the crankcase interior and with at least one transfer window on the cylinder bore. It is proposed that all transfer channels have an average length as measured from the discharge opening to the transfer window, the average length being at least 1.5 in relation to the stroke, and that the volume of the crankcase interior including all transfer channels is at most 3.1 in relation to the piston displacement.

  • Patent number: 11946396
    Abstract: An easily serviceable liquid filter assembly having a housing with a drain to provide draining of fluid (e.g., liquid) from the housing. The filter assembly has a fluid inlet to receive dirty fluid into the housing, a fluid outlet to expel filtered fluid from the housing, and a drain, when open, to expel unfiltered (dirty) fluid from the housing. By removing a cover from the housing, the filter element opens the drain so that all fluid in the housing can be directly collected or can flow into the oil pan to be collected with the fluid present in the pan. All fluid, now in the drain pan, can be drained and collected in a disposable container such as a plastic pouch, which can be recycled. The filter element can be removed from the housing via the removed cover.
