Description

Technical Field

[0001] The utility model relates to the technical field of engine system temperature regulation, in particular to an engine system and a vehicle having the same. Background Art

[0002] The combustion products of gas engines contain a large amount of water. When the gas engine is matched with a heavy-duty vehicle, the ambient temperature is low, the gas temperature after intercooling is low, and the throttle exhaust gas recirculation valve (EGR) is closed, the water in the leaked exhaust gas will freeze on the exhaust gas recirculation valve and in the mixer due to the large zero-point leakage of the exhaust gas recirculation valve, the small exhaust gas leakage flow, the low temperature, the low temperature at the valve and the wall of the related pipeline.

[0003] In a low temperature environment, for example, when the ambient temperature is below -25℃, the air temperature after the intercooler is basically equal to the ambient temperature, and the exhaust gas recirculation valve is closed or very small during low speed and low load or idling, and the zero-point leakage of the exhaust gas recirculation valve is large, causing water-containing exhaust gas to enter the downstream and mix with the air after the intercooler, causing ice to form on the surface of the mixer. As time goes by, the amount of ice accumulates and grows, eventually blocking and stalling the engine. At this time, there is no additional heat source at the exhaust gas recirculation valve position, and the wall temperature is approximately equal to the ambient temperature. The condensed water vapor freezes near the leakage gap. When the leakage is large, the valve body temperature rises slightly to form frost ice. As the leakage gradually decreases, the ice form changes to bright ice, which causes the exhaust gas recirculation valve to get stuck and report an error, and the engine is underpowered.

[0004] At present, in the prior art, a method for solving the ice jam of the exhaust gas recirculation valve system and the mixer is to install a water jacket during the production of the parts and use the coolant to heat the valve and the mixer.

[0005] However, the engine water pump must provide power for the cooling system circulation, and also provide coolant circulation for the warm air. For heavy trucks with hydraulic retarders, it must also provide retarder coolant circulation. In addition, for National VI gas engines with exhaust gas recirculation valves, coolant is also needed to dissipate heat from the exhaust gas recirculation valve and the exhaust gas venturi, that is, the exhaust gas recirculation valve heat dissipation cooling cycle. This causes the water pump to consume too much power. At the same time, in cold environments, the warm air will not be hot, the warm-up time will be long, and there will be a lot of customer complaints, resulting in increased fuel consumption of the entire vehicle, poor power, reduced engine service life, increased failure rate, and regular cleaning of scale in the entire water circuit.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Please refer to Figure 1 and Figure 2 As shown, the utility model provides an engine system, including a component to be heated 10, and the engine system also includes: a heating sleeve 20, which is sleeved on the component to be heated 10, and a heating gap is arranged between the tube wall surface of the heating sleeve 20 and the surface of the component to be heated 10; a vortex tube 30, the vortex tube 30 includes a hot air port 301 and a cold air port 302, and the hot air port 301 is connected to the heating sleeve 20, so that the hot air flow in the vortex tube 30 flows into the heating gap through the hot air port 301 to heat the component to be heated 10.

[0025] According to the engine system provided by the utility model, it includes a component to be heated 10, wherein the engine system also includes a heating sleeve 20 and a vortex tube 30, the heating sleeve 20 is sleeved on the component to be heated 10, and a heating gap is arranged between the tube wall surface of the heating sleeve 20 and the surface of the component to be heated 10; the vortex tube 30 includes a hot air port 301 and a cold air port 302, and the hot air port 301 is connected to the heating sleeve 20 so that the hot air flow in the vortex tube 30 flows into the heating gap through the hot air port 301 to heat the component to be heated 10. By arranging a vortex tube 30 in the engine system, the vortex tube 30 is used to heat the component to be heated 10, without using the pump body or coolant in the engine starting component, thereby reducing the consumption of the water pump and not affecting the power performance of the vehicle. In addition, the heating sleeve 20 is sleeved on the component to be heated 10, and the hot air flow in the vortex tube 30 is directly introduced into the heating sleeve 20. The heating gap is used to directly heat the component to be heated 10, which can quickly heat the component to be heated 10 and improve the heating efficiency.

[0026] Specifically, the component to be heated 10 of the present application includes: an exhaust gas recirculation valve 101 and a mixer 102, and the heating sleeve 20 includes: a first heating sleeve 201, which is sleeved on the exhaust gas recirculation valve 101; a second heating sleeve 202, which is sleeved on the mixer 102, and the second heating sleeve 202 and the first heating sleeve 201 are connected to each other; wherein, the hot gas port 301 is connected to an end of the first heating sleeve 201 away from the second heating sleeve 202, and the hot air flow in the vortex tube 30 flows through the first heating sleeve 201 and the second heating sleeve 202 in sequence to heat the exhaust gas recirculation valve 101 and the mixer 102. By connecting the first heating sleeve 201 and the second heating sleeve 202 to each other, the hot air flow can continue to flow into the second heating sleeve 202 after flowing through the first heating sleeve 201, and there is no need to set a gas delivery pipeline of the vortex tube 30 for the second heating sleeve 202 separately, thereby simplifying the structure. Preferably, the first heating sleeve 201 and the second heating sleeve 202 are connected via the seventh pipeline 56. Since the exhaust gas recirculation valve 101 and the mixer 102 also need to be connected to the gas path in the engine starting system, the first heating sleeve 201 and the second heating sleeve 202 are connected via the seventh pipeline 56 to avoid affecting the engine starting system.

[0027] Here, the component 10 to be heated is not limited to the exhaust gas recirculation valve 101 and the mixer 102 , but may also be other components that need to be heated.

[0028] Further, the engine system further includes: an intercooler 40, the intercooler 40 is connected to the mixer 102 through the first pipeline 50; an engine 41; a second pipeline 51, the two ends of the second pipeline 51 are respectively connected to the mixer 102 and the engine 41; wherein, one end of the second heating sleeve 202 away from the first heating sleeve 201 is connected to the first pipeline 50. In this way, the end of the second heating sleeve 202 away from the first heating sleeve 201 is connected to the first pipeline 50, and after the hot air flow flows out of the second heating sleeve 202, it can be mixed with the gas in the first pipeline 50 to increase the intake amount of the engine. Preferably, the second heating sleeve 202 is connected to the first pipeline 50 through the eighth pipeline 57.

[0029] In the specific implementation process, the engine system also includes: an air filter 42; a supercharger 43, the air filter 42 and the supercharger 43 are connected through a third pipeline 52, and the supercharger 43 and the intercooler 40 are connected through a fourth pipeline 53; wherein the cold air port 302 is connected to the third pipeline 52. Since the vortex tube 30 has a cold air flow outlet and a hot air flow outlet during operation, after the cold air port 302 is connected to the third pipeline 52, the cold air flow is directly mixed with the air flow in the third pipeline 52, and the mixed air flow flows through the supercharger 43, the intercooler 40 and the mixer 102 in sequence and then flows into the engine. In the process of flowing through the first pipeline 50, it continues to mix with the gas flowing out of the second heating sleeve 202, which greatly increases the intake volume of the engine and improves the economic performance and power performance of the whole vehicle.

[0030] In the present application, the engine system further includes: an air compressor 44; an air tank 45, the air outlet of the air compressor 44 is connected to the air tank 45; a first control valve 46, which is arranged between the air tank 45 and the air inlet of the vortex tube 30, and the first control valve 46 is connected to the air tank 45 and the vortex tube 30 respectively, and the on-off between the air tank 45 and the vortex tube 30 is controlled by the first control valve 46. The air tank 45 is used to store gas, and the air compressor 44 is used to provide power for the gas flowing into the vortex tube 30. When the heating component 10 needs to be heated, the first control valve 46 is controlled to open, so that the vortex tube 30 works.

[0031] Furthermore, the engine system also includes: a second control valve 47, which is arranged between the hot gas port 301 and the first heating sleeve 201, and the second control valve 47 is respectively connected to the vortex tube 30 and the first heating sleeve 201, and the on-off between the hot gas port 301 and the first heating sleeve 201 is controlled by the second control valve 47; a temperature detection component 48, which is used to detect the ambient temperature; a control module 49, the first control valve 46, the second control valve 47 and the temperature detection component 48 are respectively connected to the control module 49, and the control module 49 is used to receive the temperature signal of the temperature detection component 48, and control the first control valve 46 and the second control valve 47 to open or close according to the temperature signal. Among them, the temperature detection component 48 is a temperature sensor, which is used to detect the ambient temperature. The ambient temperature is the ambient temperature of the vehicle. When the ambient temperature is too low, the heated component 10 is prone to produce frost or condensed water. At this time, the control module 49 controls the first control valve 46 and the second control valve 47 to open, the vortex tube 30 works, and the generated hot air flow is discharged into the first heating sleeve 201 and the second heating sleeve 202 through the second control valve 47.

[0032] In the embodiment provided in the present application, the engine system further includes: a radiator 60, in which a heat dissipation pipeline 601 is arranged, and a hot air port 301 is connected to the heat dissipation pipeline 601 to introduce hot air flow into the heat dissipation pipeline 601; and a blower is arranged opposite to the heat dissipation pipeline 601, and the blower blows air to the heat dissipation pipeline 601 to blow out the air flow emitted by the heat dissipation pipeline 601. The air flow blown out by the radiator 60 is used to heat up the cab.

[0033] The engine system further includes: a fifth pipeline 54, the two ends of which are respectively connected to the hot gas port 301 and the first heating sleeve 201; a sixth pipeline 55, the two ends of which are respectively connected to the air outlet of the heat dissipation pipeline 601 and the fifth pipeline 54; a second control valve 47, which is arranged between the fifth pipeline 54 and the sixth pipeline 55, and is respectively connected to the fifth pipeline 54 and the sixth pipeline 55; wherein the second control valve 47 is a three-way valve. The on-off between the fifth pipeline 54, the sixth pipeline 55 and the first heating sleeve 201 is controlled by the three-way valve. According to actual needs, the hot air flow out of the vortex tube 30 flows into the first heating sleeve 201 and the second heating sleeve 202 through the sixth pipeline 55 after flowing through the heat dissipation pipeline 601 to heat the exhaust gas recirculation valve 101 and the mixer 102.

[0034] Specifically, the radiator 60 includes a heat exchange chamber, and the heat dissipation pipeline 601 is arranged in the heat exchange chamber. The engine system also includes: an engine 41, and a circulation pipeline 410 for circulating coolant is arranged on the engine 41; at least a part of the circulation pipeline 410 is arranged in the heat exchange chamber to exchange heat with the airflow emitted by the heat dissipation pipeline 601. In this process, the temperature of the hot airflow flowing out of the vortex tube 30 is relatively high, which can take into account the heating of the cab and the heating of the circulation pipeline 410.

[0035] In specific implementation, Figure 1 As shown, when the vehicle is powered on, when the ambient temperature is lower than -25°C, the control module 49 determines that heating is required, and controls the high-pressure gas to enter the vortex tube 30 through the first control valve 46, controls the second control valve 47 (three-way valve), and flows the generated high-temperature gas through the exhaust gas recirculation valve 101 and the heating sleeve 20 of the mixer 102. The heated gas enters the pipeline after the intercooler 40 (the first pipeline 50), and the cold end output gas of the vortex tube 30 enters the intake pipeline before supercharging (the third pipeline 52), increasing the overall intake volume of the engine. When the driver enters the cab, the vehicle is generally powered on first, and then the instrument lights start to light up and there are related actions. The driver adjusts the seat or fastens the seat belt, accompanied by other finishing actions. This process is more than ten seconds or tens of seconds, and then starts, and the engine starts to idle from rest. During this process, the device has been heating the exhaust gas recirculation valve 101 and the mixer 102, which eliminates the ice generated by the last parking in advance to a certain extent.

[0036] like Figure 2 As shown, when the driver in the cab thinks that the heater is not hot enough when the vehicle is just started, or that the heater needs to be strengthened, the driver presses the switch for strengthening the heater, and then the control module 49 controls the second control valve 47 (three-way valve) to allow the high-temperature hot air to flow through the heater radiator, and provide warm air to the cab under the action of the blower. After heating the radiator, the hot air flows through the heating sleeves of the exhaust gas recirculation valve 101 and the mixer 102 for heating.

[0037] The cold end gas from the vortex tube 30 and the gas with a certain pressure after heating the fuel at the hot end enter the engine intake pipe as the engine intake. Therefore, the present application realizes the heating function while increasing the overall intake volume of the engine, improving the economy and power of the whole vehicle.

[0038] The cold end gas from the vortex tube and the gas with a certain pressure after heating the fuel at the hot end enter the engine intake pipe as the engine intake. Therefore, the present application realizes the heating function of the exhaust gas recirculation valve 101 and the mixer 102 while increasing the overall intake volume of the engine, thereby improving the economy and power of the whole vehicle.

[0039] The vortex tube is an energy diversion device that controls and reaches the required temperature and flow rate through an internally replaceable generator (the lowest temperature of the air generated at the cold end can reach -46°C, and the highest temperature of the air generated at the hot end can reach 127°C). The air intake uses compressed air, which enters the vortex chamber tangentially through the nozzle flow channel. After the vortex is generated in the vortex chamber, the vortex gas entering the hot end tube undergoes energy separation in the process of flowing to the hot end, and gradually separates into cold and hot streams. The outer layer of gas flows along the wall from the inlet to the hot end outlet, the temperature gradually increases, and flows out from the hot end outlet. The inner layer of gas flows from the hot end valve to the cold end outlet on the axis, the temperature gradually decreases, and finally flows out from the cold end outlet.

[0040] The utility model also provides a vehicle, comprising an engine system and a vehicle body, wherein the engine system is arranged on the vehicle body, and the engine system is the engine system of the above embodiment.

[0041] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

By arranging a vortex tube 30 in the engine system, the vortex tube 30 is used to heat the component to be heated 10, without using the pump body or coolant in the engine starting component, thereby reducing the consumption of the water pump and not affecting the power performance of the vehicle. In addition, the heating sleeve 20 is sleeved on the component to be heated 10, and the hot air flow in the vortex tube 30 is directly introduced into the heating sleeve 20. The heating gap is used to directly heat the component to be heated 10, which can quickly heat the component to be heated 10 and improve the heating efficiency.

[0043] In addition, the present application replaces the traditional coolant heating method and has a better heating effect; it can increase the engine air intake; it reduces the water pump power and improves the economy and power of the whole vehicle; it is more reliable than other heating methods and reduces the failure rate of the whole vehicle; it has a relatively simple structure, is easy to implement, and has a low cost; it reduces the operating cost of the whole vehicle; and it improves the driving experience of the driver and passengers.
