What is the relation between combustion temperature and ignition?

The relationship between combustion temperature and ignition lies in the need for sufficient heat to initiate and sustain the combustion process. Ignition occurs when the fuel reaches a temperature known as the ignition temperature, which is necessary for the chemical reaction to commence.

When combustion occurs at a high temperature, it ensures that the fuel and oxidizer can react efficiently, thus maintaining the necessary energy for continuous burning. Also, higher combustion temperatures often lead to a more complete and efficient burning of the fuel, further contributing to sustained ignition.

In contrast, lower temperatures may not provide enough energy to overcome the activation energy barrier for fuel molecules to react with oxidizers. This is why it's crucial for combustion to maintain a high temperature to ensure that the ignition continues effectively.
