Cummins engine unveiled at Beijing Machinery Exhibition Cummins 2.8 up to 15 liters of light, medium and heavy-duty electronically controlled engines , with a power range of 46 to 675 horsepower, to meet non-road national IV emissions standards through the use of advanced post-disposal technologies. The 6.7-liter QSB series and the 9-liter QSL series displayed at this year's show have reduced nitrogen oxide (NOx) emissions through the addition of a Cummins Selective Catalytic Reduction Aftertreatment Unit (SCR).
In the large and medium-sized commercial vehicle market, SCR post-processing has become the main technical route for emission reduction upgrades, and the infrastructure for urea supply and addition has gradually improved. The SCR post-processing technology has a smaller impact on the host equipment and end customers, eliminating the need to install a cooled exhaust gas recirculation (EGR) post-treatment device (abbreviated as EGR-Free), enabling a smooth upgrade from State III to State IV, saving installation space, Small size, light weight, good fuel economy, strong adaptability of oil, and consistent with Cummins' latest EU Stage V emission solution, it provides a universal power platform for Chinese OEMs to meet international standards.
As early as November 2007, Cummins launched a technical solution that meets Tier 4 Interim/Stage IIIB standards. At present, the high-end markets in Europe and America are already in the stage of upgrading Tier 4 Final/Stage IV. As an engine manufacturer with the largest number of Tier 4 construction machines and the richest application experience, Cummins has provided power upgrades for more than 300 mainframe Tier 4 Final devices. The types of equipment include diggers, loaders, forklifts, and rotary machines. Drilling, road planers, skid-steer loaders, pavers, cranes, etc. reflect Cummins' strong technical strength. Cummins has made product and technical preparations for the fourth phase of China's non-road upgrading.
2019EU Stage V is the most stringent non-road emission standard today. The measurement of particulate emissions is more stringent. The measurement standard limit is adjusted to the amount of particulate matter (1012 per kilowatt-hour). As a result, the role of diesel particulate filters is even more important, effectively removing 99.9% of particulate emissions.
The new generation of Stage V engine introduced by Cummins has stronger performance, more than 10% increase in power, up to 20% in torque, and 3% in fuel and urea consumption, depending on the actual application conditions. The engine oil change cycle can reach 1000 hours, and the use cost is lower. It not only helps to increase the productivity of the host equipment, but also is more versatile globally. It can withstand up to 5000 ppi of sulphur content and is suitable for use in other regions outside of North America and Europe. It is the best choice for driving the world.
Cummins' all-in-one Single ModuleTM is currently used in Stage V, 4-cylinder F3.8 and B4.5 series and 6-cylinder B6.7 and L9 series engines. It neatly arranges diesel particulate traps (DPFs), selective catalytic reduction systems (SCRs), and urea injection systems in a compact vessel, eliminating the need for exhaust gas recirculation (EGR) and avoiding excessive heat sinks. After-treatment system installation space can be reduced by 50% and weight can be reduced by 30%. It is not only easy to install, but also easy to use. It can reduce emissions through full passive regeneration. It has strong adaptability, can be maintenance-free, has no impact on the host equipment, and is more economical to operate.
