Motorists in cold areas must install parking heaters on their cars

Introduction to parking heater: in addition to defrosting the windshield and heating the interior of the vehicle, the heater can also effectively improve the cold start performance of the vehicle and improve the bad emission of cooling the vehicle. In addition to defrosting the windshield and heating the interior of the vehicle, the heater can also effectively improve the cold start performance of the vehicle, Improve the bad emission of cool cars. All friends who drive have experienced the feeling when they first entered the car on a winter morning - it's freezing to the bone. If we catch up with the heavy snow that has just fallen, it will be even worse if the windshield is covered with ice and snow. After igniting the engine for a few minutes, he hurried on the road, which is far from the normal working temperature of the engine. At this time, the engine can not enter a good working state in time, and the exhaust emission seriously exceeds the standard. These are many problems we face when using cars in winter. However, if your car is equipped with a parking heater, the situation is different. Today's parking heater also has remote control and preset functions, which can be remotely controlled at any time or set to automatically warm the car in advance. Without starting the vehicle engine, the computer of the heater can start the heater by itself to heat the cabin and engine. When you open the door, a comfortable and warm warm current will come to you immediately. The main components of parking heater can be divided into heater body, circulating pump, metering oil pump, intake muffler, exhaust muffler, timer and remote control. The working principle and working process of the parking heater are installed in series with the engine cooling cycle. Firstly, the remote controller or timer sends a start signal to the ECU, the metering oil pump pumps oil from the oil tank and sends the fuel to the metal felt in front of the combustion chamber in the form of pulse. The pen igniter heats to about 900 ℃, vaporizes and ignites the splashed small oil droplets, and the flame transmits the heat energy to the engine coolant. When the preset starting temperature is reached, the air conditioning blower starts to operate and blow hot air into the vehicle. At the same time, the engine is preheated by the heated coolant. When starting the engine, it needs more cold air, so it needs more cold air to warm up the engine. At the same time, the three-way catalytic converter also needs to be heated before it can play its role. It also requires hotter exhaust emissions to reach the temperature required for operation. As a result, up to 80% of hydrocarbon emissions occur within two minutes of engine start-up. The test shows that after using the parking heater for 30 minutes, it can reduce the emissions of, hydrocarbons, nitrogen oxides, etc. produced by engine cold start by 67%! In addition, because the engine is preheated, the wear degree is greatly reduced. According to the data, the engine wear of the former is five times that of the latter at 40 ℃ and 80 ℃. It can be imagined how much damage the engine will be caused by starting the car at minus 20 ℃. The heater also consumes fuel and electricity. The heater generates heat by consuming fuel, and also consumes part of the battery energy.
