What is the temperature inside a car engine cylinder?

[VonLukas]

Car engine cylinder temperature is approximately 90°C. Here is relevant information about car engines: Classification: According to the working method of the intake system, they can be divided into four types: naturally aspirated, turbocharged, mechanically supercharged, and twin-charged. Principle: A four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good combustible mixture, which is drawn into the cylinder during the intake stroke. The mixture is compressed, ignited, and burned to generate thermal energy. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and outputs mechanical energy through the connecting rod, crankshaft, and flywheel mechanism. A four-stroke gasoline engine completes a working cycle during the intake stroke, compression stroke, power stroke, and exhaust stroke.

The temperature inside the engine cylinder varies greatly depending on the operating conditions. Under normal operation, such as during high-speed driving, the temperature in the cylinder combustion chamber can reach around 1600 to 2000 degrees Celsius—that's the peak value at the moment of ignition. During steady driving, the average temperature is typically about 400 to 600 degrees Celsius due to the heat released from burning the air-fuel mixture. I often remind myself that excessively high temperatures can cause knocking or damage components, so the cooling system is crucial. Poor heat dissipation can cause temperatures to soar into dangerous zones, such as exceeding 800 degrees Celsius, which triggers the dashboard warning light. During routine maintenance, regularly checking the coolant level and radiator condition can prevent overheating, especially after prolonged driving in summer. When the engine is under heavy load, such as climbing hills or accelerating, the temperature rises rapidly.

As a car owner, I always worry about abnormal temperatures when encountering engine issues. The normal in-cylinder temperature averages 400 to 600 degrees Celsius while driving, and can surge to over 2000 degrees during ignition. If the coolant warning light flashes, it may indicate a cooling system malfunction or insufficient coolant, allowing temperatures to exceed the dangerous threshold of 800 degrees Celsius. I've also noticed weather factors – during cold winter starts, the engine warms up slowly with lower temperatures, potentially affecting combustion efficiency; while in summer traffic jams, temperatures rise quickly. To prevent problems, I've developed a habit: checking coolant concentration and ensuring the fan operates properly every 5000 kilometers. Temperature runaway not only wastes fuel but may also cause cylinder scoring or even fire hazards, so I always stop to observe dashboard readings.

I'm always curious about the internal temperature of the engine when playing with cars. On the racetrack, the combustion chamber of the cylinder can instantly reach over 2000 degrees Celsius—that's why it can unleash such tremendous power! During normal driving, it averages around 500 degrees Celsius, but high-speed racing can push it to over 1000 degrees, bringing performance thrills while also increasing wear risks. I often check the fan and coolant to ensure everything stays within controllable limits. Temperature spikes may also be related to air intake or fuel.
