Vehicle ignition is difficult in winter.

Solutions to difficulties in automobile ignition and starting;

1, low battery. The power consumption of cars in winter is higher than that in other seasons, mainly due to the decrease of battery capacity caused by the decrease of temperature, coupled with the long-term operation of air conditioners in the cab. It is also very simple to solve. Pay attention to the battery charge every day and charge it in time.

2. The oil flow is not smooth. In winter, especially in the northern region, the temperature is abnormally low, the viscosity of engine oil increases and the fluidity decreases, which leads to the increase of resistance of engine pistons, crankshafts and other components. The above are the main reasons for the difficulty in starting in winter. The solution is to help the engine warm up. If there is sun, move the car to the sun and start it later.

3. The exhaust pipe is not smooth. Due to long-term use, the throttle accumulated a lot of carbon, and the exhaust pipe froze. Because the waste gas contains burnt water vapor, it will freeze to the exhaust pipe at low temperature, resulting in poor exhaust pipe. The solution is to put the car in a warm place after the car stops running, to prevent the water vapor in the exhaust pipe from freezing, and to form the habit of cleaning the exhaust pipe.

4. The function of automobile electronic throttle is to control the amount of air entering the cylinder, thus generating negative pressure. Because the fuel can't burn completely in the cylinder, a lot of carbon particles will be left after combustion, and carbon deposition will occur over time. As the engine temperature decreases, these carbon deposits will adhere to the throttle valve, and the performance of the throttle valve will decrease. The solution is to clean up carbon regularly.
