Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle equipment technology, and in particular to engines and vehicles. Background Technology
[0002] Antarctica possesses extremely rich mineral, marine biological, and freshwater resources, which play a crucial role in future global development. However, the extremely low temperatures and pressures of Antarctica pose significant challenges to scientific research, astronomical observation, and resource extraction. The average annual temperature in Antarctica is approximately -20°C, with minimum temperatures reaching -77°C to -85°C. In such low temperatures, engine oil in vehicles becomes more viscous and its flowability decreases, hindering oil atomization and combustion. This also increases resistance in moving parts, making it difficult to start the generator. Therefore, a low-temperature start-up preheating device is installed to ensure reliable engine starting at low temperatures.
[0003] Existing generator low-temperature start-up preheating equipment mostly uses electric radiation heaters to convert the electrical energy of the battery into heat energy to preheat the generator body and working environment. The optimal temperature of the battery is 20°C. The power output capacity is also significantly reduced under low-temperature conditions such as Antarctica. In addition, the electric radiation heater and other equipment consume a lot of electricity, and the battery cannot meet the power demand of the electric radiation heater. Utility Model Content
[0004] The purpose of this invention is to provide an engine and vehicle to solve the problems of high power consumption of existing engine low-temperature start-up preheating equipment and insufficient power supply by the battery.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] On the one hand, the present invention proposes an engine, including a water jacket and a circulation pipeline connected to the water jacket. The engine also includes a fuel heater and a first heater. The fuel heater and the first heater are both disposed in the circulation pipeline. The fuel heater and the first heater can at least selectively heat the coolant in the circulation pipeline. The first heater is an electric heater and can be electrically connected to an external power source.
[0007] As a preferred technical solution for the aforementioned engine, both the fuel heater and the first heater are equipped with temperature sensors.
[0008] As a preferred embodiment of the aforementioned engine, the engine further includes a second heater capable of heating the water jacket.
[0009] As a preferred technical solution for the aforementioned engine, the second heater is an electric heater and can be electrically connected to the external power source.
[0010] As a preferred technical solution for the aforementioned engine, the second heater is equipped with a temperature sensor.
[0011] As a preferred embodiment of the aforementioned engine, the engine further includes an oil pan and a third heater, wherein the third heater is capable of heating the engine oil in the oil pan.
[0012] As a preferred technical solution for the aforementioned engine, the third heater is an electric heater and can be electrically connected to the external power source.
[0013] As a preferred technical solution for the aforementioned engine, the third heater is equipped with a temperature sensor.
[0014] On the other hand, the present invention also proposes a vehicle, which includes a vehicle body and an engine as described in the above-mentioned scheme, wherein the engine is mounted on the vehicle body.
[0015] As a preferred technical solution for the aforementioned vehicle, the vehicle is also provided with an interface through which the first heater, the second heater, and the third heater can all be connected to the external power source.
[0016] The beneficial effects of this utility model are:
[0017] The engine and vehicle proposed in this utility model include a water jacket and a circulation pipeline connected to the water jacket, as well as a fuel heater and a first heater. Both the fuel heater and the first heater are disposed in the circulation pipeline. The fuel heater and the first heater can at least selectively heat the coolant in the circulation pipeline. The first heater is an electric heater and can be electrically connected to an external power source. When the engine is in a low-temperature environment, the battery's power output is significantly reduced, failing to meet the engine's heating requirements. Therefore, when an external power source is available, it powers the first heater to heat the coolant in the circulation pipes. To further increase the heating efficiency, a fuel heater can also be used to heat the coolant in the circulation pipes. When no external power source is available, the fuel heater heats the circulation pipes. The coolant heated by the first heater and / or the fuel heater flows through the cylinder block and cylinder head, bringing the engine to its starting temperature and enabling it to start normally. This ensures the engine's good performance and lifespan. Without relying on battery power, this effectively solves the problem of the engine failing to start in low-temperature environments such as Antarctica, thus ensuring battery charge and the normal operation of the vehicle.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] like Figure 1As shown, the present invention proposes an engine, including a water jacket 1 and a circulation pipe 2 connected to the water jacket 1. The engine also includes a fuel heater 3 and a first heater 4. Both the fuel heater 3 and the first heater 4 are disposed in the circulation pipe 2. The fuel heater 3 and the first heater 4 can at least selectively heat the coolant in the circulation pipe 2. The first heater 4 is an electric heater and can be electrically connected to an external power source. When the engine is in a low-temperature environment, the battery's power output capacity is significantly reduced, failing to meet the engine's heating requirements. Therefore, when an external power source is available, it powers the first heater 4 to heat the coolant in the circulation pipe 2. To further increase the heating efficiency of the circulation pipe 2, a fuel heater 3 can also be used to heat the coolant in the circulation pipe 2. When no external power source is available, the fuel heater 3 heats the circulation pipe 2. The coolant heated by the first heater 4 and / or the fuel heater 3 flows through the cylinder block and cylinder head, allowing the engine to reach its starting temperature and thus enabling it to start normally. This ensures the engine's good performance and lifespan. Without relying on battery power, this effectively solves the problem of the engine failing to start in low-temperature environments such as Antarctica, thus ensuring battery charge and the normal operation of the vehicle.
[0027] Optionally, the engine cooling system also includes a radiator and a thermostat, with the fuel heater 3 and the first heater 4 both located on the circulation pipe 2 between the thermostat and the engine water jacket 1.
[0028] To further improve the heating efficiency of the coolant in the engine, the engine also includes a second heater 5, which can heat the water jacket 1.
[0029] Optionally, the second heater 5 is an electric heater and can be electrically connected to an external power source. Heating the second heater 5 with an external power source can not only increase the temperature of the coolant in the water jacket 1, thereby achieving rapid and efficient preheating of the generator's operating environment, but also effectively ensure the charge of the battery inside the vehicle body.
[0030] Furthermore, temperature sensors are provided in the fuel heater 3, the first heater 4, and the second heater 5. This configuration allows for the detection of the temperature within the fuel heater 3, the first heater 4, and the second heater 5.
[0031] The engine also includes an oil pan 7 and a third heater 6. The third heater 6 heats the engine oil in the oil pan 7. By heating the oil pan 7 with the third heater 6, the engine oil stored in the oil pan 7 can be heated, thereby reducing the viscosity of the engine oil and improving its fluidity. This ensures that the engine oil can be delivered to all parts of the engine under the pressure of the oil pump, ensuring the normal starting and operation of the engine and avoiding fuel loss caused by preheating the vehicle due to cold engine start.
[0032] Optionally, the third heater 6 is an electric heater and can be electrically connected to an external power source. Heating the third heater 6 with an external power source not only increases the temperature of the engine oil in the oil pan 7, but also effectively maintains the charge of the battery in the vehicle body. Moreover, compared with traditional fuel and gas heaters, electric heaters avoid fuel and gas emissions, making them cleaner and more environmentally friendly.
[0033] Furthermore, the third heater 6 is equipped with a temperature sensor. This configuration allows for the detection of the temperature within the third heater 6.
[0034] By heating the circulation pipe 2 through the fuel heater 3 and the first heater 4, heating the water jacket 1 through the second heater 5, and heating the oil pan 7 through the third heater 6, the coolant and engine oil in the engine can be heated to increase the engine temperature, thereby ensuring the normal starting and operation of the engine.
[0035] This invention also proposes a vehicle comprising a vehicle body and an engine, the engine being mounted on the vehicle body. Even in low-temperature environments such as polar regions, the engine can still rapidly warm up and start.
[0036] The vehicle is also equipped with interfaces through which the first heater 4, the second heater 5, and the third heater 6 can be connected to an external power source. These external power sources supply power to the first heater 4, the second heater 5, and the third heater 6 via the vehicle's interfaces, ensuring their stable operation.
[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
