2024 Cummins ISL G (EPA 07) ISL G 280 Transit Bus
The ISL G spark ignited natural gas engine meets 2010 U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emission standards. The engine is based on the 8.9 liter diesel automotive (ISL) platform and shares many installation options with the diesel counterpart.
The ISL G features stoichiometric EGR combustion technology with spark ignition. Stoichiometric EGR combustion creates an oxygen free exhaust, enabling the use of maintenance-free three way catalyst after-treatment. The ISL G offers performance benefits as well, with over 30% more torque at idle than its predecessor the C Gas Plus, the same rated speed as the ISL diesel and improved efficiency.
Features may include:
- ISL 8.9 block and major options shared with Diesel product
- Viscous crankshaft vibration damper and related options
- Cooled EGR system
- Redesigned fuel module and engine intake air arrangement
- Maintenance Free three-way catalyst after-treatment
- Smaller frame, water cooled, wastegate turbocharger
- Open crankcase breather system
- New Cummins Engine Control Module (ECM)
- Single 18.7 CFM or twin 30.4 CFM air compressor with increase drive through torque
- Increased capacity front end accessory belt drives
- Increased flow water pump
- Enhanced reliability through product upgrades, and common components
- Maintenance Intervals similar to ISL, with simplified maintenance to lower costs.
- Combination bypass and full-flow oil filter
- Same base warranty coverage as diesel. Extended Warranty options available.
