, along with the smaller 6B5.9). The first electronic version, known as the ''C8.3E'' and designed for the urban bus market exclusively, went into production in late 1996. The ISC was introduced in 1998 and used a CAPS electronically controlled injection system along with a 24 valve head, vs 12 valves on the 6C8.3. By late 2003, Cummins announced that they will revise the engine to sport a High-Pressure Common-Rail (HPCR) system to help with emissions and also a variable geometry turbocharger system to help with the performance on this engine. The Cummins ISC also has a sister engine which is designed off the existing ISC 8.3-litre
