Description

Technical Field

[0001] The utility model belongs to the technical field of engines, and more specifically relates to a constant temperature throttle system and a car. Background Art

[0002] Hybrid engines often use high compression ratios and deep Miller cycles to improve the thermal efficiency of the engine, thereby reducing the fuel consumption of the entire vehicle to achieve energy conservation.

[0003] The winter temperature in the Northeast region is generally between -20℃ and -40℃. The operating point of the hybrid vehicle engine is relatively stable. The high-temperature gas discharged from the engine's vent encounters the low-temperature intercooler and other intake pipe walls. The water vapor in the air condenses into ice and adheres to the pipe wall or the throttle valve shaft. As time goes by, the amount of ice on the throttle valve increases. In severe cases, the valve may get stuck, causing power system failure and panic among the driver.

[0004] When driving in high-temperature areas in the summer, the environment in most parts of the country will be above 30°C, and the corresponding temperature after the intercooler is 50°C. Due to the high intake temperature and low intake density, the overall intake volume is affected. Combined with the characteristics of the high thermal efficiency hybrid engine, the power performance is reduced. Utility Model Content

[0024] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] The utility model provides a constant temperature throttle system, comprising:

[0026] A throttle valve having an air cavity disposed therein;

[0027] The heat unit is connected to the air cavity through a pipeline, and a power unit is arranged on the pipeline;

[0028] The control unit starts and stops the power unit according to the outdoor temperature.

[0029] Specifically, since the throttle may freeze or the intake density may decrease when the vehicle is in a cold or hot environment, the heat unit on the vehicle is connected to the air cavity of the throttle, and a power unit is arranged between the two. When a change in the temperature outside the vehicle is detected, the control unit can start the power unit and introduce the air from the heat unit into the air cavity, which can change the temperature at the throttle, thereby changing the temperature of the air passing through the throttle, thereby avoiding throttle freezing and reduced intake density.

[0030] Optionally, the heat unit is a cabin, and one end of the pipe is arranged at the front of the cabin.

[0031] Specifically, the heat unit is an area that can provide a constant temperature or a small temperature difference. The cabin can be used as a heat unit. The air temperature in the cabin is generally controlled at about 25°C, which is a relatively comfortable temperature range. The air in the cabin is guided to the air cavity of the throttle through a pipeline with the help of the power unit, and the temperature of the throttle is adjusted, so that the throttle can be basically in a constant temperature or a relatively small temperature range. In addition, the air outlet of the air conditioner can also be used as a heat unit. When the temperature outside the car is high, the air outlet of the air conditioner sends out cool air, and at the same time, the cool air is introduced into the air cavity of the throttle to reduce the temperature around the throttle and avoid the air density being reduced due to excessive temperature. When the temperature outside the car is low, the air outlet of the air conditioner sends out hot air, and at the same time, the hot air is introduced into the air cavity of the throttle to increase the temperature around the throttle and avoid ice formation due to too low temperature, and the problem of throttle flipping and jamming.

[0032] Optionally, a filter screen is provided on one end of the pipeline.

[0033] Specifically, since the air in the front of the cabin needs to be introduced into the air cavity of the throttle, a filter can be set at the air inlet of the pipe to filter the air in the cabin and discharge it into the pipe, thereby preventing dust in the cabin from entering the power unit and affecting the service life of the power unit.

[0034] Optionally, the other end of the pipe is connected to the air cavity, and the other end of the pipe is arranged toward the X positive direction.

[0035] Specifically, the pipe is connected to the air cavity port. Since the hot gas needs to be delivered to the throttle of the front engine compartment, in order to reduce the backflow of the intake air at the front end of the vehicle into the pipe, the pipe outlet discharged into the front engine compartment is directed to the rear of the vehicle.

[0036] Optionally, the power unit is a blower, and the blower is connected to a battery.

[0037] Specifically, a blower can be set in the pipeline as a power unit, and the air in the pipeline can be sent into the air cavity of the throttle when the battery provides power. Using a commercially available blower as a power unit can reduce the manufacturing cost of the constant temperature throttle system, and the blower adopts conventional technology and is not prone to failure.

[0038] Optionally, the power unit is arranged in the front cabin.

[0039] Specifically, when the blower is used as a power unit, the blower needs to be installed in the front engine compartment. Since the blower has a small power requirement and relatively low noise, it can be integrated with the sound of the powertrain in the front engine compartment to reduce the NVH perception of the driver and passengers.

[0040] Optionally, a temperature sensor is provided on the throttle valve, and the temperature sensor is connected to the control unit.

[0041] Specifically, in addition to referring to the temperature outside the vehicle, the operation of the constant temperature throttle system can also monitor the temperature at the throttle. When the throttle temperature changes and reaches the set temperature threshold, a control instruction can be sent to the control unit, so that the power unit can be started, thereby accurately adjusting the throttle temperature to avoid icing of the throttle and reduced intake density.

[0042] Optionally, the pipeline includes a first air pipe and a second air pipe, the first air pipe is arranged between the heat unit and the power unit, and the second air pipe is arranged between the power unit and the air cavity.

[0043] Specifically, the pipeline arranged between the air cavity and the heat unit can be divided into a first air pipe and a second air pipe. The two air pipes respectively use a whole pipeline and are arranged at both ends of the power unit, thereby reducing the probability of air leakage during the transmission process.

[0044] The utility model also provides an automobile, comprising the above-mentioned constant temperature throttle system.

[0045] Example

[0046] like Figure 1 As shown, the utility model provides a constant temperature throttle system, comprising:

[0047] A throttle valve 1 is provided with an air cavity therein;

[0048] The heat unit is connected to the air cavity through a pipeline, and a power unit is arranged on the pipeline;

[0049] The control unit starts and stops the power unit according to the outdoor temperature.

[0050] In this embodiment, the heat unit is the cabin 2, and one end of the pipe is arranged at the front of the cabin.

[0051] In this embodiment, a filter screen is provided on one end of the pipeline.

[0052] In this embodiment, the other end of the pipe is connected to the air cavity, and the other end of the pipe is arranged toward the X positive direction.

[0053] In this embodiment, the power unit is a blower 3, and the blower 3 is connected to a battery.

[0054] In this embodiment, the blower 3 is disposed in the front nacelle 4 .

[0055] In this embodiment, a temperature sensor is provided on the throttle valve 1 , and the temperature sensor is connected to the control unit.

[0056] In this embodiment, the pipeline includes a first air pipe 5 and a second air pipe 6. The first air pipe 5 is arranged between the cabin 2 and the blower 3, and the second air pipe 6 is arranged between the blower 3 and the air cavity.

[0057] The utility model also provides an automobile, comprising the above-mentioned constant temperature throttle system.

[0058] In summary, in the cold winter, the temperature of the intake air cooled from the cylinder is basically close to the external environment temperature. If the engine wants to burn the mixed air entering the cylinder, it needs to absorb the heat of the engine itself to heat the intake air and increase the thermal energy of the mixed air, which requires more energy consumption. By adopting the constant temperature throttle system, the air of about 25°C in the cabin 2 is introduced into the air cavity of the throttle 1, so that the intake air can be preheated at the throttle, which not only reduces the heat absorbed by the cold mixed air from the engine, but also can increase the temperature of the throttle and reduce the risk of throttle icing. In the hot summer, the temperature of the cooled gas is often 25°C higher than the ambient temperature. The high-temperature gas has a low density. Under the same pressure ratio, the higher the temperature, the smaller the corresponding gas volume, and the lower the power of the whole vehicle. At the same time, the deep Miller cycle of the hybrid engine is sensitive to the demand for gas volume, which further affects the power performance of the engine. By adopting the constant temperature throttle system, the air at about 25°C in the cabin 2 is introduced into the air cavity of the throttle 1, which can cool the gas passing through the throttle and increase the gas volume, thereby improving the power performance of the whole vehicle.

[0059] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
