Detailed Description
Referring to FIG. 1A, a schematic diagram of an engine system 100 is shown, according to an illustrative embodiment. The engine system 100 includes an oil tank 102, an oil pump 104, a regulator 106, a pressure regulator 128, an oil cooler 108, an oil thermostat 110, a filter bypass 112, an oil filter 114, a turbocharger 116, an adapter 118, one or more PCNs 120, a first main ejector 124, a second main ejector 126, a pressure regulator 128, one or more main bearings 130, one or more connecting rod bearings 132, one or more camshaft bearings 134, one or more rockers and ibake 136, an on-cam idler 138, an off-cam idler 140, a power take-off idler 142, an idler 144, and an air compressor 146.
The system 100 delivers oil from a tank 102 to an oil cooler 108 via an oil pump 104. In some embodiments, the oil may be any suitable lubricant for engine system 100. The oil pump 104 may be controlled by a regulator 106. The oil pump 104 is connected to an oil cooler 108. The oil cooler 108 receives oil from the oil pump 104 and cools the oil to a desired temperature. The temperature of the oil passing through the oil cooler 108 may be monitored by an oil thermostat 110. The oil cooler 108 is connected to an oil filter 114. Oil filter 114 receives oil from oil cooler 108 and filters the oil. In some embodiments, all of the oil is filtered by the oil filter 114, and no oil flows through the filter bypass 112. In some use cases, at least some oil from oil cooler 108 bypasses oil filter 114 through filter bypass 112. The filter bypass 112 may remove small contaminants from the oil to support efficient operation of the engine system 100.
The first portion of oil from the outlet of the oil filter 114 or from the oil cooler 108 is delivered to the adapter 118. A second portion of the oil from the outlet of the oil filter 114 or from the oil cooler 108 is delivered to the second primary ejector 126. As used herein, an "ejector" refers to a passage, channel, or manifold that receives a fluid at an inlet and provides a fluid flow to one or more components connected to one or more outlets of the ejector. A third portion of the oil from the oil filter 114 or oil cooler 108 is delivered to the turbocharger 116.
The first part of the oil delivered to the adaptor 118 is further delivered to the first primary jet 124 through the adaptor 118. The first portion of oil is used to cool the cylinders of the engine via one or more PCNs 120. The oil in first primary jet 124 is transported to one or more PCNs 120. The one or more PCNs 120 are configured to deliver oil to one or more cylinders (not shown) of the engine. Adapter 118 includes a valve (a solenoid valve in various embodiments) configured to control the flow rate of oil to first primary jet 124 and the flow rate of oil flowing through one or more PCNs 120. The valves of the adapter 118 are configured to control the amount of oil delivered to the one or more PCNs 120 for cooling. According to some embodiments, the adapter 118 is a separate component from the engine. The adapter 118 is mounted to the engine. In some embodiments, if the solenoid valve fails, the solenoid valve may be kept fully open by default to avoid the risk of engine overheating.
The second portion of oil delivered to the second main injection 126 is used to lubricate various components of the engine system, such as the main bearings 130, the connecting rod bearings 132, the camshaft bearings 134, the rocker and ibake 136, the cam upper idler 138, the cam lower idler 140, the power take off idler 142, the idler 144, and the air compressor 146. The second primary jets 126 are separated from the first primary jets 124 so that no fluid communication is formed between the first primary jets 124 and the second primary jets 126.
First primary jets 124 are disposed on the cold side (e.g., intake side) of the engine. The second primary jets 126 are disposed on the hot side (e.g., exhaust side) of the engine. The second primary jet 126 is connected to the oil filter 114 and/or the filter bypass 112 through the oil passage 122. An oil passage 122 is also connected to the adaptor 118 to deliver the first part of oil to the first primary jet 124.
Referring to FIG. 1B, a schematic diagram of an embodiment of a portion of an engine system 150 is shown. The engine system 150 is generally similar to the engine system 100 shown in FIG. 1A, with the only difference being the portion shown in FIG. 1B. This portion of the engine system 150 includes an oil filter 152, a first primary jet 154, a second primary jet 156, one or more PCNs 158, and one or more adaptors 160. The oil filter 152, the first main injection members 154, and the second main injection members 156 are substantially similar to the corresponding parts in fig. 1A (for example, the oil filter 114, the first main injection members 124, and the second main injection members 126, respectively).
In the engine system 150, each of the one or more PCNs 158 is coupled with an adapter 160. The one or more adapters 160 are configured to control a flow rate of oil directed to each of the PCNs 158. In an exemplary embodiment, the adapter 160 includes a solenoid valve for regulating the flow of oil, although any other type of regulating valve suitable for the application may be implemented. In some cases, each of the one or more adapters 160 provides the same flow rate of oil to each of the one or more PCNs 158. Each of the one or more adapters 160 may provide oil to the one or more PCNs 158 at different flow rates without requiring the same flow rate of oil to each of the one or more PCNs 158.
FIG. 2 is a schematic diagram of a PCN control system 200 within an engine block, according to an illustrative embodiment. The PCN control system 200 may be used to control a PCN flow of an engine system (e.g., the engine system 100 shown in fig. 1). The PCN control system 200 includes a first primary ejection member 202 and a second primary ejection member 204.
The first primary ejector 202 is located on the cold side of the engine block. The second primary jet 204 is located on the hot side of the engine block. The first primary jets 202 are fluidly connected to one or more PCNs (not shown). In some embodiments, the first main jet 202 receives oil through an adaptor including a solenoid valve (or other type of valve). The oil flow to the first main jet 202 is controlled by a solenoid valve. The first primary jet 202 delivers oil to one or more PCNs for cooling the pistons of the engine. The flow rate through the first primary jet 202 and one or more PCNs can be controlled using a solenoid valve.
The first primary jets 202 are separated from the second primary jets 204 so that no fluid can flow directly between the two primary jets. The second primary jet 204 receives oil at the hot side of the engine block and delivers the oil to one or more components of the engine for lubrication of the one or more components.
Fig. 3 is a schematic diagram of an adapter 300 for a PCN control system, according to an illustrative embodiment. The adapter 300 may be used similarly to the adapter 118 of fig. 1 and the adapter of the PCN control system 200 of fig. 2. The adapter 300 includes an oil passage 302, a housing 304, and a solenoid valve 306 (or other type of valve).
The housing 304 is mounted to an engine block 308. The oil passage 302 receives oil from an oil filter or filter bypass (not shown). The oil passage 302 is connected to the casing 304 and delivers oil through the casing to the PCN jet (not shown). The PCN ejection members are similarly configured as the first primary ejection members 124 of fig. 1 and the first primary ejection members 202 of fig. 2. The housing 304 is connected to a solenoid valve 306. The solenoid valve 306 is configured to control the flow rate of oil flowing through the casing to the PCN jet. The solenoid valve 306 is used to provide a required flow rate of oil to one or more PCNs for cooling cylinders of an engine block 308. The solenoid valve 306 may be controlled according to one or more of an engine load, an engine temperature, and an engine oil pressure of the engine.
