What is the reason for Ford Maverick's black exhaust barrel?

As follows: 1. Generally speaking, the exhaust pipe of vehicles burning engine oil will emit blue exhaust gas, indicating that too much engine oil enters the combustion chamber to participate in combustion; Secondly, in addition to the exhaust pipe, the oil port may appear blue from time to time. If a similar situation occurs, it is burning oil.

2. Another method is to pull out the dipstick for inspection. If the amount of oil is obviously reduced in a short time, it may also be burning oil. For example, if the engine oil is lower than the scale of the dipstick during two maintenance periods, it can basically be determined that it is burning engine oil.

3. In our daily car use, we might as well check the engine oil condition of the vehicle, choose high-quality engine oil and gasoline according to the vehicle and our actual car use, and maintain the vehicle in a fixed period to minimize the probability of burning engine oil.

1, clean the throttle

Take off the engine trim cover, remove the throttle and clean it with carburetor cleaner. Dry with cotton cloth and install. Cleaning the throttle valve is basically recommended by maintenance personnel every time they go to the 4S shop.

Under normal circumstances, the cleaning cycle of the throttle valve is 20,000 kilometers. According to different brands and models, the charges of 4S stores vary greatly. Actually, just buy a bottle of carburetor cleaner.

2. Remove the carbon deposit inside the engine.

Open the oil cover, pour in the whole tank of cleaning agent (mixed with old oil), then cover the oil cover, turn off the engine after the ignition is idling for 10 minutes, and clean the carbon deposit inside the engine. The cleaning agent can dissolve sludge, colloid, water, metal chips and other deposits in the engine, reduce the pollution of new engine oil and prolong the service life of the engine. Its cleaning cycle is generally 30 thousand kilometers.

The cleaning method of engine carbon deposit is also very simple. Before maintenance, just add a bottle of engine internal cleaning agent to the oil port, idle for about 10 minutes, and then immediately maintain and replace the oil filter.
