Abstract
Methods and systems are provided for adjusting a flow profile of a windage tray. In one example, a method for operation an engine system is provided that includes operating an engine to perform combustion, determining an engine speed, and adjusting a flow profile of a plurality of deflectors in a windage tray positioned in a crankcase based on the engine speed.
Claims20
A method for operating an engine system comprising:
- operating an engine to perform combustion;
- determining an engine speed;
- and
- adjusting a flow profile of a plurality of deflectors in a windage tray positioned in a crankcase based on the engine speed.
1 more element
An engine system comprising:
- a lubricant reservoir receiving lubricant from lubricated components;
- a lubricant pump positioned in the lubricant reservoir;
- a crankshaft positioned in a crankcase vertically above the lubricant reservoir and receiving rotational input from a piston rod;
- a windage tray positioned vertically between the lubricant pump and the crankshaft, the windage tray including a plurality of deflectors extending longitudinally along the windage tray;
- and
- code stored in memory executable by a processor to:
- increase a degree of opening of the plurality of deflectors in response to a decrease in engine speed.
4 more elements
A method for operating an engine system comprising:
- operating an engine with an engine speed is greater than a threshold value;
- and
- in response to operating the engine with the engine speed greater than the threshold value, adjusting a position of flow deflectors in a windage tray to decrease the flowrate of crankcase gas through openings in the windage tray.
