Problems solved by technology

[0005] However, the use of solenoid valves can cause some problems
[0006] Firstly, the assembly of the solenoid valves requires wires in order to connect the valves to the ECU, which leads to complexity in the wiring of the entire engine system
[0007] In addition, the use of solenoid valves controlled by the ECU requires dedicated software running on the ECU, which causes a computational load on the ECU
[0008] These facts, combined with the cost of the solenoid valve itself, add to the cost of the engine system

Embodiment Construction

[0038] Preferred embodiments will be described with reference to the accompanying drawings.

[0039] Some embodiments can include automotive systems 100 such as figure 1 and figure 2 As shown, it includes an internal combustion engine (ICE) 110 having an engine block 120 defining at least one cylinder 125 having a piston 140 coupled to rotate a crankshaft 145 disposed in a crankcore. Cylinder head 130 cooperates with piston 140 to define combustion chamber 150 . A fuel and air mixture (not shown) is placed in combustion chamber 150 and ignited, resulting in thermally expanding exhaust gases to cause reciprocating motion of piston 140 . Fuel is provided by at least one fuel injector 160 and air is drawn through at least one air intake 210 . Fuel is provided to fuel injector 160 at high pressure from fuel rail 170 in fluid communication with high pressure fuel pump 180 which increases the pressure of fuel from fuel source 190 . Each cylinder 125 has at least two valves 215 ...

Abstract

The invention relates to a valve (500) for controlling piston cooling nozzles (560) in an internal combustion engine (110), said valve (500) comprising a valve body (640) equipped with means for transferring oil from The oil inlet (610) sucked by the oil passage (570) and the oil outlet (630) used to connect with the piston cooling nozzle channel (550), wherein the valve body (640) is equipped with the air from the engine (110 ) into the intake manifold (220) of the air inlet (660) and is equipped with a valve element (620) configured to be driven by the pressure of the oil entering the oil inlet (610) and the pressure of the air entering the air inlet (660) ).

Description

technical field [0001] The invention relates to a valve for controlling piston cooling nozzles in an internal combustion engine. Background technique [0002] An internal combustion engine (ICE) for a motor vehicle generally includes an engine block defining at least one cylinder housing a reciprocating piston connected to a rotating crankshaft. The cylinder is closed by a cylinder head which cooperates with a reciprocating piston to define a combustion chamber. A fuel and air mixture is cyclically fed into the combustion chamber and ignited, creating thermally expanding exhaust gases that cause the piston to reciprocate. Fuel is injected into each cylinder through the corresponding fuel injector. Fuel is provided to each fuel injector at high pressure from a fuel rail in fluid communication with a high pressure fuel pump that increases the pressure of fuel from a fuel source. [0003] Generally, internal combustion engines are provided with a lubrication system that incl...
