What happens when there is lean burn in a combustion engine? Does the reaction complete quicker? Is that why it is hotter?
Curl said:I'm not convinced that the extra fuel really has any significant effect in cooing the combustion chamber. An extra 0.0002 grams of fuel is nothing, keeping in mind that the latent heat of vaporization of gasoline is even lower than water, and the heat capacity of the chamber is significantly higher.

Lean burn in cars refers to the process of adjusting the air-to-fuel ratio in the engine to create a leaner mixture. This means that there is a higher proportion of air to fuel, leading to better fuel efficiency and lower emissions.
Lean burn can improve car performance by increasing fuel efficiency and reducing emissions. However, it can also decrease power and torque, which may affect acceleration and top speed.
Lean burn can result in a hotter engine because when there is more air in the mixture, it takes longer to burn the fuel. This delay in the combustion process allows more heat to build up, leading to a hotter engine.
A hotter engine can have several benefits, including improved fuel efficiency, reduced emissions, and better engine longevity. It can also help prevent the buildup of carbon deposits in the engine, which can negatively impact performance.
While lean burn can offer several benefits, there are also potential downsides. These include reduced power and torque, potential engine damage if the engine runs too hot, and the need for more frequent maintenance to prevent overheating or engine damage.
