Test 8 - Fuel Injector Balance Test

This test determines if fuel injectors are metering an equal quantity of fuel when they are commanded open. By measuring fuel pressure drop during a timed cycle of opening each injector, a relative evaluation of each injectors flow rate is made. This test is designed to identify injectors with significant differences in flow rate but will not identify problems with an injector flow pattern (e.g., improperly sized spray cone, non-uniform spray cone (pattern), mis-directed spray cone, etc.)
