16.21 A single-cylinder, four-stroke gas engine has a bore of 180 mm and astroke of 330 mm and is governed on the hit and miss principle. Whenrunning at 400 rpm at full load indicator card are taken which give aworking loop mean effective pressure of 6 bar and a pumping loop meaneffective pressure of 0.4 bar. Diagrams from the dead cycle give a meameffective pressure of 0.6 bar. When running on no load a mechamicalcounter recorded 50 firings strokes per minute.
