Definitions
- the invention relates to a device for cooling at least one piston of an internal combustion engine according to the preamble of claim 1.
- the invention has for its object to provide a method which ensures an optimized piston cooling such that the Internal combustion engine is improved in terms of their overall efficiency.
- a non-return valve in the main supply line or a non-return valve per supply line is used in a known manner, the lubricating oil pump for regulating the pressure within the lubricating oil circuit for adapting to different operating states of the internal combustion engine being load-dependent. Due to the load-dependent control of the lubricating oil pump, a non-return valve can be used which works with an increased opening pressure compared to a non-return valve of a system without a lubricating oil pump controlled according to the load. This avoids unnecessary piston cooling in many operating states.
- the lubricating oil pump is controlled as a function of additional operating parameters - in particular as a function of the speed of the internal combustion engine and / or the temperature of the internal combustion engine and / or the coolant temperature of the internal combustion engine and / or the lubricating oil temperature.
- Figure 1 a first device according to the invention.
- Figure 1 shows a schematic representation of a device for cooling the pistons 2 (or the at least one piston) of an internal combustion engine.
- the device comprises one Lubricating oil pump 10, which supplies the piston 2 with lubricating oil via a feed line 12 for cooling.
- a check valve 14 is arranged in the feed line 12 between the lubricating oil pump 10 and the outlet opening 12a of the feed line 12.
- the lubricating oil pump 10 is controlled by a control unit 20, which ensures that the lubricating oil pump 10 is regulated as a function of the determined load of the internal combustion engine.
- the lubricating oil pump 10 is preferably controlled via the control unit 20 (for example an engine control unit) by means of a map control as a function of a plurality of operating parameters.
- the control is carried out as a function of the engine temperature, the engine speed and / or the lubricating oil temperature. Due to the load-dependent regulation of the lubricating oil pump 10, the check valve 14 can be designed for an increased opening pressure.
- a check valve 14 in the conventional, non-load-dependent control of the lubricating oil pump of an internal combustion engine in a motor vehicle is designed for an opening pressure of approximately two bar - in order to ensure sufficient piston cooling even in all critical conditions -
- a check valve 14 with a higher opening pressure than this - for example an opening pressure of three bar - is used.
- valves one valve per supply line
- main supply line connected to the supply lines (not shown).
