Cummins showcases 15L fuel-agnostic engine platform; hydrogen, diesel, biogas

At CONEXPO, Cummins showcased its new fuel-agnostic 15-liter motor system with hydrogen, pure fuel and superior diesel engines offering low-to-zero carbon gasoline capacity. The following-generation engine is developed to accelerate the decarbonization of hefty-obligation off-freeway purposes.

Cummins’ all-new system usually takes inner combustion to a new level, able of conference long run ultra-minimal emission criteria, these types of as EPA Tier 5 and EU Phase 6, jointly with a very low-to-zero carbon fuel capacity to aid place building and quarrying internet sites on a decreased price tag route to decarbonization.

The 15-liter has a important maximize in electric power density with a far more compact installation envelope delivering devices makers with the capacity to do extra with their equipment.

The new engine is a clear sheet layout that points to the foreseeable future of diesel: a lot more capacity with a lot less environmental impact. It presents higher energy density in critical off-road applications which includes excavators, wheel loaders, drilling rigs, road setting up, milling devices, haul vehicles and air compressors. Innovatively intended components offers reduced weight with most engine sturdiness.

The fuel-agnostic architecture of the 15-liter platform utilizes a widespread foundation motor with cylinder heads and gasoline units specially tailored for it to use carbon-free of charge hydrogen or biogas with up to a 90{ca2182fc8fed51dc37b95061ee48b5056cde1176732b225548c54a0c0156d303} carbon reduction.

Cummins’ 15-liter hydrogen has rankings up to 530 hp (395 kW) and all-natural fuel up to 510 hp (380 kW). The highly developed diesel version can use both sustainable HVO gasoline or biodiesel with scores up to 650 hp (485 kW) for the most demanding off-freeway duty-cycles.

A critical structure characteristic of the new platform is a Double-Overhead-Camshaft (DOHC) realizing important developments in combustion and thermal efficiency. Friction losses throughout the engine structure have also been reduced and a sculpted block contributes to body weight conserving. The DOHC style also permits a a lot more economical integral motor brake to be accommodated.

The 15-liter hydrogen motor with immediate-injection, lean-burn combustion will be out there with scores from 400-to-530 hp (298-395 kW) and a peak torque of 2600 N·m. Running on zero-carbon environmentally friendly hydrogen, it can use a 700-bar pressure substantial-potential gasoline storage method for optimum running hours involving refueling.

The 15-liter innovative diesel characteristics Cummins hottest XPI extremely-high tension gas injection technique and will offer a broad power vary of 450-to-675 hp (335-503 kW) with 3000 N·m peak torque. Making use of B100 biodiesel permits up to a 70{ca2182fc8fed51dc37b95061ee48b5056cde1176732b225548c54a0c0156d303} reduction in carbon and utilizing HVO renewable gasoline achieves up to a 90{ca2182fc8fed51dc37b95061ee48b5056cde1176732b225548c54a0c0156d303} reduction.

For apps driven by renewable biogas, the 15-liter normal fuel will offer rankings extending from 400-to-510 hp (298-380 kW) with a peak torque of 2500 N·m obtainable. Extremely minimal sounds is a more benefit of this engine, significantly for when operating in city spots.

Going forward, our intention is to offer the exact same agnostic ability across the following-generation of our present-day 6.7 liter and 9 liter motor platforms.
