 AIR DENSITY METER FOR ENGINE TUNING

Standard engineering charts readily show the effect of air temperature and barometric pressure on engine power output. The maximum power output of an engine is directly related to "air density", provided the same fuel/air ratio is maintained. If the fuel/air ratio is permitted to go rich or lean, the reduction in power output is considerable greater. In addition, the ignition timing will be fast or slow and the spark plug heat range will be affected. To maintain a balance of these conditions and secure maximum power output at a given "air density" the correct fuel/air ratio must be maintained. The Air Density Gauge combines the factors of air temperature and barometric pressure and gives a direct reading in percent air density.
