1. Expanding the air-fuel mixture slower is not an option to let a combustion engine deliver more net work. Slowing down the expansion of the mixture would reduce the overall efficiency of the engine.
2. Adding more fuel before combustion is an option to let a combustion engine deliver more net work. Increasing the amount of fuel will lead to a more powerful combustion, resulting in increased net work output.
3. Compressing the air more is an option to let a combustion engine deliver more net work. Increasing the compression ratio allows for a higher pressure during combustion, resulting in increased net work output.
4. Expanding the air less is not an option to let a combustion engine deliver more net work. Limiting the expansion of the air would reduce the work done by the engine and decrease overall efficiency.
Which of the following is/are not (an) option(s) to let a combustion engine deliver more net work? (Multiple correct an 1.Expand the air-fuel mixture slower 2. Add more fuel before combustion 3. Compress the air more 4. Expand the air less
