Abstract: Engine air tightness is an
important target that is Engine compression system performance.The design
depends on theorem of pneumatic gauging.The measuring result is displayed by
the digital display differential pressure type and pneumatic gauging
instrument,through imitating the air tightness about valves.The instrument that
detects the air tightness is simple operation,convenient,express,to detect in
high efficiency and high efficiency.
