With energy input
When calculating efficiency, work input is compared to the work output. Efficiency is the ratio of the work output to the work input, expressed as a percentage. It shows how effectively a system converts input energy into useful output energy.
Energy efficiency compares the energy output of a system to its energy input. It indicates how much of the input energy is converted into useful output energy, with higher efficiency values indicating less energy wasted.
Efficiency is the ratio of useful energy output to total energy input. A higher efficiency indicates that a greater proportion of the total energy input is being converted into useful energy output. Therefore, as efficiency increases, the amount of useful energy output relative to total energy output also increases.
Energy efficiency is typically calculated as the ratio of useful energy output to total energy input. The equation to calculate energy efficiency is: Energy Efficiency = (Useful Energy Output / Total Energy Input) x 100%.
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.

compare the two stroke and four stroke engine in power output and thermal efficiency?
The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
ratio of energy output to energy input.
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
Efficiency in energy transformations can be calculated by dividing the useful output energy by the total input energy and multiplying by 100 to express it as a percentage. The formula is efficiency = (useful output energy / total input energy) x 100%. A higher efficiency value indicates a more effective conversion of input energy into useful output energy.
Efficiency compares energy output with input, providing a measure of how effectively energy is being converted or utilized in a system or process. It helps in evaluating the performance and effectiveness of energy conversion technologies or practices.
efficiency eta = output / input where output is the amount of mechanical work or energy released by a process, and input is the quantity of work or energy used to run the process. Due to the principle of conservation of energy, energy efficiency within a closed system can never exceed 100%. At a loutspeaker you have electrical Voltage as input and sound pressure as output. The efficiency of the loudspeaker is really only 1 percent.
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
