subject: The Analysis Of Car Start Failure In Winter Morning [print this page] Sudden cooling, all of a sudden people feel the footsteps of winter that has come around. Early in the morning, the owner Mr. Lin was on the phone to complained: when went out in the morning, the car that had served him five years even can not start, so he had a crowded bus to work, almost late. But evening coming home to try again, Mr. Lin found that the car everything was normal. In winter morning, the car why not start? "Mr. Lin asked.
The main reasons of failed car start in winter are the following:
1. The battery power is low. The winter most direct impact on the family car in the city is the battery. At low temperatures, the power consumption of the car will be significantly greater than the other seasons. Because of the low temperature environment, the battery will becomes electrically capacity decrease. At the onset of winter, in a time to the franchise store to have the supplementary electric of battery, or replace them with new battery, you can avoid this situation effectively.
2. The oil flow is blocked. This is more obvious in the extremely low temperatures. In the winter, the viscosity of the oil will follow larger, oil flow becomes more difficult, so that the engine resistance increased, which resulted in difficulty in starting the car in cold winter. In this case, the contingency approach is to place the car in warm environment, you can normally start after a period of time. If you want to completely solve the problem, you had better go to specialty stores to do a winter maintenance, and replace it with a suitable oil in accordance with local conditions.
3. Exhaust pipes freeze, the electronic throttle carbon deposition catching. Exhaust pipe freeze situation occurred at a relatively close distance between home and office. Their car using frequency is low, the water vapor in the engine after combustion freeze in some parts of the exhaust pipe, and the short-distance traveling are not sufficient to allow these icing melting and after one night there are more ice. For a long time, it will impact on the start and an exhaust of the vehicle. Of course, the solution is actually very simple, you can have a long travel in high-speed road every weekend in the winter, so that the accumulation of water in the exhaust pipe drain in a timely manner by a strong force of exhaust.
In addition, the vehicle's electronic throttle is an apparatus to control the flow of air entering the cylinder to generate a negative pressure. Gasoline in the combustion chamber is not completely burned, resulting in a tiny carbon particles, thereby forming the "coke" which we often call that. With the temperature decrease of the entire engine after the engine is turned off, these "coke" will be more stubborn to fix on the throttle valve, make the flexibility of the throttle valve deteriorated, so the throttle in the rotation appears catching phenomenon. With lower winter temperatures, it is recommended that owners periodically clean the electronic throttle fully to eliminate the vehicle instability and increased fuel consumption by throttle coke.
