Business Unit (EBU)

The Engine Division produces and distributes diesel and natural gas engines with a wide range of power and corresponding component products for use in the automotive, industrial, and power generation industries. Cummins engine displacement ranges from 1.4 to 91 liters, and the power range covers 31 to 3500 horsepower. It is widely used in road vehicles such as heavy trucks, medium trucks, buses, recreational and recreational vehicles, light commercial vehicles and pickup trucks, as well as engineering machinery, mining equipment, Off-highway equipment such as agricultural machinery, ships and railways. Cummins engines are not only known in the industry for first-class reliability, durability, and fuel economy, but also to meet increasingly stringent automotive emissions (US EPA 2007/2010, European Nos. 4 and 5), and off-highway motor equipment emissions (Tier 3 and above) And the fierce competition of marine engine emissions (IMO standard) has been in the leading position in the industry.

Advantage

First: forward-looking design and development capabilities, Cummins can develop corresponding solutions for different emission standards.

Second: mature supporting capabilities, Cummins' emission control technology can be perfectly matched with the engine life cycle and the entire vehicle, so that customers get the best economic benefits.

Third: Advanced exhaust emission control technologies, including cooled exhaust gas recirculation (COOLED EGR), selective catalytic oxygen (SCR), and particulate filter (DPF).

Fourth: Bulk procurement capabilities. With the continuous expansion of the Cummins emission aftertreatment market, a batch procurement scale has been formed to provide customers with cost-effective products.

The Difference

The M-series engine has a displacement of 11 liters (670 cubic inches) and the N-series engine has a displacement of 14 liters (855 cubic inches).

M11 power range 168-373kW, bore x stroke: 125 x 147 mm.

N14 power range 146-358 kW, bore x stroke: 140 x 152 mm.

The M11 series engine is smaller than the N series. The M series imported parts are 56%, and the N series imported parts are only about 10%. Compared with the N series engine, the technology maturity is better than the M series. The M11 engine is more expensive than the N series engine.
