Problems solved by technology

[0003] The oil cooler in the existing engine generally draws water from the water jacket of the cylinder body, and circulates and cools the engine oil according to the size of the engine. However, since the water in the cylinder water jacket is cold water with a relatively low temperature during cold start, and the temperature rise of the cylinder water jacket is slow, the water flowing out of the cylinder water jacket has a poor preheating effect on the oil
Due to the high viscosity of low-temperature engine oil, the starting resistance of the engine is relatively large, which increases fuel consumption and emissions, making it difficult to meet the requirements of energy saving and emission reduction

Embodiment 1

[0031] see figure 1 The first embodiment provides an oil preheating system, including a thermostat 1 , a three-way solenoid valve 2 , a hot water supply device, an oil cooler 4 , an oil temperature sensor 5 and a controller 6 .

[0032] Wherein, the two water inlet ends of the three-way solenoid valve 2 are respectively connected with the water outlet end of the thermostat 1 and the hot water supply device, and the water outlet end of the three-way solenoid valve 2 is connected with the oil cooler. 4 connected.

[0033] The engine oil temperature sensor 5 is used to sense the engine oil temperature, and the engine oil temperature sensor 5 is electrically connected to the controller 6 , and the controller 6 is also electrically connected to the three-way solenoid valve 2 .

[0034] In the engine oil preheating system provided in Embodiment 1, after the engine is started, the engine oil temperature sensor 5 can sense the temperature of the engine oil in the engine, and can tran...

Embodiment 2

[0047] see figure 1 , the second embodiment provides a method for controlling the engine oil preheating system in the first embodiment above, including the following steps:

[0048] The oil temperature sensor 5 senses the temperature of the oil in the engine, and transmits the sensed oil temperature value to the controller 6 .

[0049] The controller 6 analyzes the received oil temperature value, if the oil temperature value is lower than the preset value, the controller 6 sends an opening command to the three-way solenoid valve 2, and the three-way solenoid valve 2 closes Open the passage with the hot water supply device after the opening command, and the hot water flowing out from the hot water supply device flows through the three-way solenoid valve 2 to the oil cooler 4 to preheat the oil; if the oil When the temperature is higher than the preset value, the controller 6 sends a closing command to the three-way solenoid valve 2, and the three-way solenoid valve 2 closes th...

Embodiment 3

[0052] Correspondingly, the third embodiment provides an engine, which includes the engine oil preheating system involved in the first embodiment above (the specific structure of the oil preheating system will not be described one by one), and also includes the engine body; The engine oil preheating system is installed on the engine body.

[0053] Obviously, the engine provided by the third embodiment has all the advantages of the oil preheating system in the first embodiment because it includes the oil preheating system in the first embodiment, the starting resistance of the engine is small, and the fuel consumption and emissions are low .

[0054] In summary, the present invention discloses an engine oil preheating system, a control method and an engine, which overcome many technical defects of traditional engines. The engine oil preheating system, control method and engine provided in this embodiment have small starting resistance, low fuel consumption and low emissions wh...

Abstract

The invention relates to the technical field of engine equipment with an engine oil preheating function, in particular to an engine oil preheating system, a control method thereof and an engine. The engine oil preheating system comprises a thermostat, a three-way solenoid valve, an engine oil cooler, an engine oil temperature sensor and a controller; the two water inlet ends of the three-way solenoid valve communicate with the water outlet end of the thermostat and a hot water supplying device correspondingly, and the water outlet end of the three-way solenoid valve communicates with the engine oil cooler; the engine oil temperature sensor is used for sensing the temperature of engine oil in the engine and electrically connected with the controller, and the controller is further connectedwith the three-way solenoid valve. The control method is applied to the engine oil preheating system, and the engine comprises the engine oil preheating system. According to the engine oil preheatingsystem, the control method thereof and the engine, during cold starting of the engine, the starting resistance is small, and fuel consumption and the emission load are low.

Description

technical field [0001] The invention relates to the technical field of engine equipment with engine oil preheating function, in particular to an engine oil preheating system, a control method and an engine. Background technique [0002] The oil in the engine can lubricate the moving parts and reduce wear, and can assist the cooling of the moving parts. [0003] The oil cooler in the existing engine generally draws water from the water jacket of the cylinder body, and circulates and cools the engine oil according to the size of the engine. However, since the water in the cylinder water jacket is cold water with a relatively low temperature during cold start, and the temperature rise of the cylinder water jacket is slow, the water flowing out of the cylinder water jacket has a poor preheating effect on the oil. Due to the high viscosity of low-temperature engine oil, the starting resistance of the engine is relatively large, which increases fuel consumption and emissions, mak...
