Which mechanism prevented early atmospheric Newcomen engines from achieving higher cycle rates?

💡 Explanation

When the cylinder filled with steam, it had to be cooled to condense the steam and create a vacuum; inadequate vacuum condensation rate due to water injection limitations slowed the cycle. Therefore, inadequate vacuum condensation rate was limiting, rather than steam production, piston wear or material overheating which were secondary factors at that stage of development.
