Cummins Inc. is an American multinational corporation that designs, manufactures, and distributes engines, filtration, and power generation products.

[6] Cummins Component Business Unit consists of emission solutions, filtration (Fleetguard), fuel systems, turbo technologies (Holset), and electronics.

The Cummins Turbo Technologies unit designs and manufactures turbochargers and related products on a global scale, for diesel engines above 3 liters.

Its Emission Solutions unit develops and supplies catalytic exhaust systems and associated products to the medium and heavy-duty commercial diesel engine markets.

[9] The case has been settled, but some qualified Chrysler owners may receive $500 for repairs to the block, which was alleged to crack and create a coolant leak.

[10] Cummins has a technical center in Darlington, England, for developing products for the European, Middle Eastern, and Asian markets.

Accelera provides zero-emissions solutions including hydrogen fuel cells, batteries, e-axles, traction systems and electrolyzers.

In 2006, the division officially changed its name to Cummins Turbo Technologies to be identified more closely with its parent company.

The Onan name continues to be used for modern versions of their traditional engine-driven generators for RV, marine, commercial mobility, home standby, and portable use.

Cummins had announced a US$1 billion initiative to produce clean energy technology, including electrolyzers for hydrogen cells in Fridley.

The ISG/X12 in China has surpassed 240,000 units per year making it the highest volume heavy duty engine in the Cummins product line.

[24] The trucks used engine ECU software to engage pollution controls during the 20-minute lab tests to verify compliance with the Clean Air Act, but then quietly disabled the emissions controls during normal highway cruising, thereby emitting up to three times the maximum allowed NOx pollution.

[25] Cummins was found to have installed devices designed to bypass or disable emissions controls on 960,000 Dodge and Stellantis RAM pickup truck diesel engines between 2013 and 2023.

[27] Cummins reported Total CO2e emissions (Direct + Indirect) for the twelve months ending 31 December 2020 at 595 Kt (-94 /-13.7% y-o-y).

[28] The company plans to reduce total emissions (Direct + Indirect) 50% by 2030 from a 2018 base year[29] and also aims to reach net-zero by 2050.
