Why is the engine smoking?

[Myrtle]

Reasons for engine smoking: 1. White smoke: Large amounts of white smoke may indicate that coolant has entered the engine cylinders due to leakage between the cylinder and cooling system, evaporating into steam under high temperatures. 2. Black smoke: This is caused by incomplete fuel combustion, a dirty air filter, or faulty spark plugs. 3. Blue smoke: This occurs due to delayed maintenance, use of substandard engine oil, or failure to change the engine oil for an extended period.

I remember when I was driving on the highway, the engine suddenly started smoking, which scared me so much that I immediately pulled over. Upon opening the hood to inspect, I found that the oil filter had a poor seal, causing oil to drip onto the hot parts of the exhaust pipe and burn, producing blue smoke. From experience, common causes of engine smoke include oil leaks (such as seal or pump failures), cooling system issues (like a damaged cylinder head gasket allowing coolant to enter the combustion chamber, producing white smoke), excessive fuel leading to incomplete combustion and black smoke, or engine overheating causing plastic components to melt. Safety first, I immediately turned off the engine and called for a tow truck. Later, the mechanic said that regularly checking the oil level and coolant height could prevent such situations. During every maintenance session, I remind the technician to thoroughly inspect the pipes and seals to avoid potential hazards.

I enjoy tinkering with cars, and engine smoke is no small matter. Observe the smoke color for diagnosis: blue smoke indicates oil burning, possibly due to worn piston rings; white smoke often suggests coolant leakage, such as a cylinder gasket issue; black smoke is usually caused by improper fuel mixture or faulty fuel injectors. Common triggers also include damaged turbochargers, non-functioning cooling fans, or electrical shorts causing sparks. Immediately stop the engine, avoid touching hot components, and use a flashlight to inspect the engine compartment. For prevention, I stick to regular oil changes, clean the throttle body, and avoid extreme driving. During repairs, use diagnostic tools to scan for trouble codes and identify the root cause.

Yesterday, while driving to pick up my child, the engine started smoking. I immediately pulled over to a safe spot. The smoke was thick, and my heart was racing. After turning off the engine, I opened the hood to ventilate. Reflecting on it, it might have been due to insufficient coolant or a ruptured hose causing a leak and white smoke. From chatting with friends, I learned that engine overheating or combustion issues can also cause smoke. Fortunately, I had checked the oil level and coolant tank beforehand. Now, I do a weekly self-check, ensuring sufficient oil and coolant to keep the car in stable condition. Small issues are handled promptly, while major problems are taken to the repair shop.
