Charging pressure
Charging pressure at 100% engine
load and an ambient air temperatu-
re of approx. +20°C (68°F). Curve 2
applies to pleasure boats (output
according to curve B) and curve 1
for other installations (output accor-
ding to curve C).
A considerably lower charging
pressure is obtained if the engine is
not running at full output.
