This process involves evaluating the volume of fuel delivered by a fuel injector over a specific time period under controlled conditions. It is a diagnostic procedure used to assess the performance and functionality of these critical engine components. For example, a technician might measure the amount of fuel sprayed by an injector in milliliters per minute at a given pressure.
The assessment of injector output is essential for maintaining optimal engine performance, fuel efficiency, and emissions control. Discrepancies in fuel delivery between injectors can lead to engine misfires, reduced power, and increased pollutant output. Historically, simpler methods were employed, but modern technology allows for more precise and repeatable measurements, enabling early detection of degradation and proactive maintenance.
