    Cold start refers to the car in the case of direct start without preheating, mostly refers to the cold areas in the north, driving without preheating in the case of injury to the car is like running long distance without people doing warm-up exercises, it is easy to be injured, for the car, just start the oil has not lubricated the various parts of the engine, especially the crankshaft and crankshaft bearings, it is easy to strain, the driving capacity of the car will also decrease, and the service life of the engine will also be shortened. The best way to protect the engine is to warm it up in advance, run it for 5 to 10 minutes without load on the engine, and 15 to 20 minutes for the diesel engine, and keep the water temperature between 60 and 80 degrees, which is the optimal temperature. The measures are as follows:

    1.In winter, a high-viscosity engine oil of 10W, or 5W is suitable for winter;

    2.Excessive carbon deposition in the air intake system and at the root of the intake valve causes the mixture concentration to be too thin during cold start;

    3.The throttle is seriously dirty and the air intake is insufficient;

    4.The speed of the starter does not meet the requirements;

    5.The contact resistance of the connecting wire of the battery is too large; The battery is insufficient;

    6.The viscosity of the lubricating oil of the transmission is too thick, resulting in too much running resistance of the engine;

    7.insufficient cylinder compression pressure of the engine;

    8.The high-pressure ignition system --- poor performance of the spark plug and cannot produce an ideal electric spark sufficient to break down the mixture;

    9.The spark plug is carried out unreasonably; Engine coolant temperature sensor malfunction.

    Hope it helps!

    The oil supply system of the carburetor engine is completely dependent on the mechanical system, and the oil and gas mixture is poor in the cold state, so it is difficult to start. Even if the engine of the carburetor car has been started, its operation is very unstable and it is very easy to stall, so it is best to heat the car in situ for 30 seconds to 1 minute before driving.

    Cold start means that the engine has been turned off for a period of time, the temperature has been ** below the normal working temperature, and the oil has been reflowed, at this time the start is a cold start, so it may be a bit general, with data to explain to you, two hours of ignition, the engine temperature is lower than 40 degrees, at this time in the start is a cold start.

    Cold start hurts the car more, according to the data, the engine more than 80 wear is in the cold start, cold start due to the low temperature, gasoline is not easy to burn resulting in vehicle start difficulty, followed by the oil to cover the engine everywhere, it takes a certain amount of time, at this time the engine is running without lubrication, the machinery rubs against each other will definitely make abnormal noise.

    After a long time of parking, starting the car when the engine temperature is low is called a cold start.

    The car has been driving for a while, and the water temperature has risen. At this time, do a short stop and then start it is called hot start.

    In the case of cold start, you can drive normally at low speed and low gear for about 5 kilometers. Some people say that the water temperature is high at idle speed and then walk, I think it is easy to cause water accumulation and rust in the exhaust pipe, so it is recommended that the landlord drive at low speed and low gear after cold start.

    A cold start is when the water temperature is lower than the normal engine temperature.

    Usually the normal engine temperature is 86 degrees to 92 degrees.

    Pay attention to buy some engine oil in winter, see how the 4S store recommends, you can buy it from them, or you can look at the model and buy it outside.

    In winter, pay attention to keep the throttle clean, warm up the car for a few minutes, and then drive after the temperature rises.

    Don't look too precious on the car, run at least a few times a month at high speed, engine speed 2500-3500 rpm is the best,

    You think it's a computer Hot and cold start Hehe When the car starts, the main reason is that the oil has not been pumped up, so the wear and tear on the engine is the greatest, but there is no good way to avoid it, what can be done is to wait for 2-3 minutes after the car is hit and then start After the temperature is normal, it is running.

    A cold start of a car is when the engine water temperature is low, and the car is generally not started for a long time (such as after parking at night). When starting, first rotate the ignition switch in one gear, then the water temperature indicator on the dashboard will light up, and it will take about a few seconds for the indicator light to turn off automatically, and then you can start the engine and start without idling. The working efficiency of the engine is related to the water temperature, the experiment proves that the water temperature below 40 will consume more fuel 6%, the winter car should appropriately extend the low-gear driving time, control the speed within 3000 rpm, wait for the water temperature and lubricating oil temperature to rise and then enter the normal driving.

    In addition, you should also pay attention to the water temperature during driving, generally speaking, 70 -90 water temperature is ideal.

    It should be reminded that due to the lack of battery power, it may take more time to start the cold car in winter, but the starting time should not exceed 10 seconds each time, and the interval between two consecutive starts should be about 30 seconds. If the car really won't start, you can tow the car to a repair shop or 4S shop for inspection, so that the engine can start normally.

    Is there any good way to start a car with air conditioning? I don't think there's a good way to start a cold start, and it's best to heat up the car and start it in advance.

    In winter, it is best not to store the car in the open air, it should be in the garage with heating equipment, if it is parked in the open air, it should also be placed in a place where the sun is easy to shine, so that the temperature rises relatively quickly and is easy to start. In winter, the temperature in most parts of our country is below 0, the temperature in the north is generally around -25, and the minimum temperature in some areas is around -35. When the car is used under low temperature conditions, it is easy to cause difficulty in engine starting, increased fuel consumption, and serious wear of parts.
