"Cummins ISB engine" refers to a specific series of
diesel engines manufactured by Cummins Inc., a major power generation company. The "ISB" designation is an internal Cummins model code, and doesn't directly translate to a specific meaning in common language. These engines are known for being relatively compact and powerful, making them popular for use in:
* Medium-duty trucks: This is a primary application for ISB engines.
* Buses: Especially in smaller to mid-size buses.
* Industrial equipment: Such as generators, construction machinery, and agricultural equipment.
In short, it's a brand and model identifier specifying a type of robust, reliable diesel engine produced by Cummins.
