Working principle of water heating system What is the structure and principle of water heating system?
Water heating and warm air system is mainly composed of blower and warm air box. The principle is simpler. After the warm air is turned on, the high-temperature coolant in the automobile engine will enter the warm air box, and the air blown out by the blower will also enter the warm air box, so that the air outlet will blow out warm air. The warm water tank is actually a heat exchanger. When using the heating function, be sure to pay attention to the use method. If used improperly, it will also lead to an increase in automobile fuel consumption. Don't turn on the warm air immediately after the engine starts in winter. Turn on the heater after normal driving 10 to 15 minutes. After starting the engine, the engine temperature is relatively low. Turning on the warm air at this time will cause the engine to heat up too slowly and increase fuel consumption. After starting the engine in winter, the idle speed is higher than usual. This is because the engine temperature is too low, so the ecu will instruct the fuel injection system to inject more fuel to warm up the engine quickly. Some riders still have the habit of keeping warm in winter. In fact, local heating is useless, and local heating will only increase exhaust emissions and fuel consumption. The correct way to warm up a car is to start the engine first and then shift gears, just don't let the engine speed be too high when starting. Driving in gear after the engine is started can also make the gearbox oil reach the working temperature quickly, which is also good for the gearbox.
The water just flooded the chassis. What's wrong? There is water in the car. The water just flooded the chassis. What's wrong?
If the water only floods the chassis, as long as it is not soaked for a long time, it will be fine. About the wading depth of a car, it is generally based on the half-wheel height, which is a safe wading height put forward by some old drivers or some experts, so we still judge it according to the actual situation. Pay attention to the depth, direction and velocity of water before driving, and judge whether there are obstacles such as silt and quicksand underwater. Before wading, the distributor and high-voltage line are also wrapped in plastic sheets. Observe the route and speed of the vehicle ahead, and judge whether the vehicle can pass by observing the depth of the accumulated water. When driving slowly on the hard road with low gear, you should keep the steering wheel and the accelerator pedal stable at the same time, so that the car can maintain enough stable power and try to avoid stopping, shifting gears or making sharp turns. If the wheels slip or sink, don't slam on the accelerator while the engine is running, and drive out of the water with the help of manpower or other vehicles. Because the water pressure is far less than the exhaust pressure of the cylinder, as long as the vehicle is not turned off, the accumulated water will not flow back. After wading, check the circuit system, immediately disassemble the electrical parts, dry the wet parts and install the fan belt. Check whether the gearbox is soaked in water, whether the floating objects between the radiators of the water tank are blocked, whether the tires are damaged, and whether there are aquatic plants entangled under the chassis. And clean the vehicle in time to restore the braking effect. Don't try to start it before making sure that there is no water in the circuit system, engine parts and other parts, so as not to cause greater losses.
