Results of the Design and Usage of a Common Rail Injector Tester

Abstract

The purpose of this research was to evaluate the design and the usage of the common rail injector tester by 5 experts derived by purposive sampling technique. The research Instrument included an experimental recording form of the design and the usage of the common rail Injector tester. Data were analyzed using descriptive statistics including mean and standard deviation. The research results showed that the common rail injector tester was evaluated for the design on: suitability, modernity, creativity, actual use, suitability assessment of materials, strength and durability of the materials, ease of purchasing the materials, color, size, and working time reduction. The overall average was 4.01±0.89 while the results of the evaluation of the usage of the common rail injector tester including speed of the operation, safety and ease of use, non-destructive testing, and working time reduction showed that the overall average was 4.02±0.92. Therefore, the design and operation of the developed common rail injector tester achieved very high quality.
