| Abstract | The operation of compression ignition engines is largely dependent upon a smooth supply of fuel from fuel injectors. Recently an increase in malfunctioning of fuel injectors in compression ignition engines of automobiles has been noticed. Statistics show that these failures are mainly attributed to the poor quality of diesel fuel available in local markets. A fundamental reason in this regard is the presence of extra water content in diesel fuel. The unwanted water content in diesel disturbs the performance of fuel injectors and renders them malfunctioning or pre-mature failure. Since modern electromagnetic fuel injectors are compact and enclosed assemblies, therefore, any observation in their internal mechanism is always difficult to measure. Most studies have been conducted to only approximate malfunctioning of fuel injectors with the help of simulations and corresponding results. Here, we have established an experimental setup using a 2KD engine of Toyota Hilux fitted with DENSO electromagnetic fuel injectors and onboard diagnostic equipment. The setup experimentally proves that fuel injectors malfunction due to high percentage of water in diesel fuel. This study will assist future equipment designers to optimize the design of fuel injectors so that the high percentage of water in diesel fuel may be catered for before production. |
