Development of a compact mobile fuel laboratory in China

This study discusses development of a mobile fuel laboratory in China, which integrates sulfur content detection device, vapor pressure testing device and fast simulation equipment for detergency detection. The compact mobile fuel lab can test detergency and sulfur content of both gasoline and diesel, and volatilization characteristic of gasoline. The research shows that taking many efficient measures to control influence factors can ensure portable devices providing reliable testing results. The main influence factors such as vehicle vibration, essential resource supply, operating conditions and data quality control have been studied in this work. Building a three dimension dynamic model, consisted of vehicle, absorber and devices, can confirm the influence of vibration. Furthermore, the solution of the model is used for guiding the design and selection of vibration damping unit. Three power supply approaches, including commercial, generator and uninterruptible power supply, can provide sufficient electricity. And split-phase circuit, voltage regulator and filter device are set up for decrease electrical signal interference. Temperature and air circulation are two important elements which should be strictly controlled; thus, automotive air-conditioning system and an additionally onboard roof type air condition work alternatively to keep ambient temperature stable, and gas concentration alarm unit interlocked together with ventilation system ensures the car in a safe gas concentration range. Experiments prove that optimized equipment has good repeatability of results. Additionally, pre-treatment and pre-assessment are effective processes for blind sample analysis.
