What is the effect of a greater weight of combustible mixture in the cylinders?

When the weight of the combustible mixture in the cylinders increases, there is more fuel and air available for the combustion process. This increased mass of the mixture allows for a more substantial amount of energy to be released during combustion, particularly because there are more fuel particles to react with the oxygen present.

As a result, with a greater weight of the combustible mixture, the potential for power development by the engine also increases, assuming other factors such as combustion efficiency, timing, and design constraints are kept optimal. A more robust charge leads to a more vigorous explosion, which can enhance the overall power output of the engine.

Furthermore, the mixture's density influences the engine's operational efficiency and performance characteristics. Therefore, having a greater weight of the combustible mixture directly correlates with the engine's ability to develop greater power under the right conditions.
