VIAIN is happy to collaborate with the world’s best Cummins marine engine manufactures to design and develop to produce the next generation QSK50 tier 5 engines. As of now QSK50 tier 4 marine engines are the best and the latest available marine engines in the market. Cummins
VIAIN’s QSK50 tier 5 model Cummins collaboration engine is well efficiently designed by VIAIN’s team of engineers and the experts from the Cummins team. This is manufactured in VIAIN’s factory to serve the industrial and marine needs with a higher combustion engine to do the optimum combustion, even in low oxygen supply areas it provides high efficiency and toxic carbon monoxide free smoke which is a mandatory requirement for the environmental safety concerns.
Cummins QSK50 tier 4 is an advanced model that is currently ruling the industry and now VIAIN and Cummins are coming up with a better replacement option for QSK50 tier 4 which means we are coming with a most advanced specification to fulfill your needs.
the next-generation QSK50 engine ready to meet EPA Tier 4 Final ultra-low emissions standards with up to 2,000 hp (1,491 kW) output for powering large mining haul trucks, excavators, and loaders.
16-cylinder, 50-liter engine
Utilizes fully integrated Cummins Selective Catalytic Reduction (SCR) after-treatment system, designed as a drop-in replacement for exhaust silencers
SCR system combined with clean-combustion enhancements enables 5% or more reduction in operating costs due to higher fuel efficiency and low consumption of Diesel Exhaust Fluid (DEF)
Durability improvements, and lower fuel burn, contribute to an extended life-to-overhaul
Operators can expect an additional 1,500 hours or more before rebuild
Oil and filter services are extended to 500-hour intervals for Tier 4 Final
Meets very low levels of 0.04 g/kW-hr Particulate Matter (PM) and 3.5 g/kW-hr for oxides of nitrogen (NOx) emissions required by Tier 4 Final
The main focus of emissions reduction takes place in exhaust stream, eliminating any potential compromises to power output or reliability
SCR after-treatment removes NOx, leaving in-cylinder combustion able to more easily focus only on PM reduction
In-cylinder temperatures and pressure remain very similar to those of the Tier 2 engine
Emissions reduction approached eliminates the need for additional on-engine systems, extra cooling or turbocharging complexity
Retains engine envelope nearly identical to that of Tier 2 predecessor
SCR system has the same space claim as that of typical Tier 2 exhaust silencers, providing an equivalent acoustic reduction
Seals on critical joints and maintenance-free crankcase breather system eliminate oil drips and mist
Fuel filters feature NanoNet filtration media for enhanced fuel cleanliness and high levels of protection for the high-pressure Modular Common Rail Fuel System (MCRS)
MCRS reaches peak torque of 5,805 lbs.-ft. (7,871 Nm)
Fueling is finely balanced across cylinders, providing low levels of vibration and ensuring that visible smoke from engine exhaust is virtually eliminated
Reduces carbon dioxide (CO2) emissions compared with older engines, which can be further enhanced by running the engine on a B20 biodiesel blend
