ECD systems include the ECD-V series (V3, V4, and V5) which implements electronic control through distributed pumps (VE type pumps), and common rail systems made up of a supply pump, rail, and injectors. Types are the ECD-V3 and V5 for passenger cars and RVs, the ECD-V4 that can also support small trucks, common rail systems for trucks, and common rail systems for passenger cars and RVs. In addition, there are 2nd-generation common rail systems that support both large vehicle and passenger car applications. The chart below shows the characteristics of these systems.
