Do I need to warm up my car for winter start?

1. How long does it take to start and warm up the car in winter? Some car owners think that the longer the warm-up time, the better, but in fact, this is a redundant move. Some car owners wait until the water temperature gauge pointer moves to the normal position before daring to start the vehicle, which is actually not necessary.

2. How long does it take to start and warm up the car in winter? The first thing to be clear is that it is very necessary to warm up the car at start. Because the temperature of the engine that has just started is low, the lubricating oil in each part is not in place, and the parts will be dry grinding and parts will be lost when starting up immediately.

3. How long does it take to start and warm up the car in winter? However, the warm-up time does not need to be too long, and the criterion for judging is that the water thermometer pointer just starts to move, or the engine tachometer falls back to idle after starting, and you can drive, which takes about a minute.

It is recommended that the owner drive at a low speed for the first 2 kilometers after starting, and then speed up normally.

Note: How long does it take to start warming up the car in winter? Due to the cold winter, a car that has been parked overnight will certainly not run smoothly in an instant when used the next day, and the car needs to be warmed up before starting.

I believe that after reading the above content, the owner has a good grasp of the time for the car to start and warm up in winter.

Need. Ignition about 30 seconds can go, try to step on the accelerator as lightly, so that the engine speed does not exceed 2000 rpm, after driving for about seven or eight minutes, the water temperature of the car will rise, when you see the water temperature gauge pointer floating, you can drive normally, turn on the air conditioning and heating.

3-4 minutes by in-situ hot car. Cold start and go, automatic transmission accumulator pressure is insufficient, the impact is large, and the clutch plate is consumed quickly. Therefore, the hot car ensures that the operation of the vehicle does not cause damage to the various parts of the car.

However, the length of the hot car process depends on the quality of the car and the season, and after the hot car, as long as the car runs smoothly and the vibration or tremor disappears, you can start slowly.

The problem of hot cars in winter should be seen from two aspects, 3-4 minutes of hot cars in situ, it is definitely good for protecting the engine, one is to let the oil fully reach the lubrication points, and let the parts be heated to achieve normal matching clearance, and then run at full load, so that the wear of the engine will be very small.

However, because the engine control module doubles the fuel supply during cold start, it is easier to start, and the rpm will be increased by 20%-30% to stabilize the idle state. In this way, one is that the vehicle is not driving, thus wasting energy, and the other is that when the cold idle, due to the increase in fuel supply and incomplete combustion, it will aggravate air pollution.

When it comes to engines, oil is an important factor in providing excellent protection for engine parts. Therefore, the biggest challenge for engine oil is that when the car is started in cold climates, especially in those areas where the daily temperature is extremely low, if the car is not effectively lubricated when starting, it may cause wear and tear on the engine, which will cause high maintenance costs over time.

As the temperature drops, the oil becomes thicker, thus losing its fluidity i.e. the ability of the oil to circulate through the engine through the oil pump. Obviously, a cold and thick oil is not good for the engine to pump.

After the car has been parked overnight, and a few hours have passed, the oil will also slowly flow into the oil pan, so the oil cannot be transported through the oil pump to the pistons where the engine needs to be lubricated the most immediately after the car is warmed up, so it is necessary to warm up the engine.

In winter, it is best to warm up the car, because the car is parked for a long time and the oil in the engine flows back into the oil pan. It takes about 30 seconds after the start of the engine to deliver the oil to the pistons, connecting rods, crankshafts and other parts of the engine that need to be lubricated the most. Here's a specific explanation of the hot car in winter:

1. From the level of oil products, the engine oil is more viscous and has poor fluidity in winter, and the in-situ hot car can make the engine oil cover the engine parts again. Therefore, do not increase the throttle to heat up the car when the car is hot, the idle speed of the engine will be protected when the cold car starts, the engine will run at a higher speed, and then slowly drop to 750-800 rpm, so at this time, you only need to let the vehicle run on its own. 2. In the north, first warm up the car for 30 seconds for 1 minute, then start slowly, warm the car while driving, and then reach the normal driving speed.

In short, try to change gears a little later than usual. In general, as long as the thermometer pointer moves, or the idle speed is reduced to less than 1000ru002fmin, you can drive at low speed, and when the coolant temperature rises, you can increase your speed. 3. In the winter in the south, it can be started in 15 seconds, and do not step on the accelerator after starting, most of the wear and tear will occur at this time (explaining why taxis are particularly durable, because the number of cold starts is relatively small.) It is best to maintain a low speed (1500-2000) and slow driving (10-40 km/h to reduce the load on the engine) until the engine reaches the normal operating temperature.
