The Use of Large Valve Overlap in Scavenging a Supercharged Spark-ignition Engine Using Fuel Injection
This 1932 NACA Technical Note, issued by the National Advisory Committee for Aeronautics, reports tests on a supercharged spark-ignition aircraft engine that used fuel injection and large valve overlap for scavenging. Its pictures are engineering graphs of brake mean effective pressure and specific fuel consumption against fuel quantity, plus a cross-section drawing of a fuel-injection valve and combustion chamber in ink-line technical style, useful to a designer for clean plotted data charts and precise sectional line work.
