The Cummins QSK95: One of the Most Powerful Diesel Engines in the World

September 5, 2020

The Cummins QSK95 rules the seas. It’s one of the world’s largest diesel engines available, and many marine boats around the globe are already using the engine’s incredible Cummins power for various applications. Alongside its power, the QSK95 is designed for minimized environmental impact, making it attractive to many environmentally conscious companies.

Want to know more about what makes the QSK95 the most powerful diesel engine? Keep reading to find out the immense Cummins power this engine carries, as well as the many features that make it so impressive.

 

The Most Powerful High-Speed Diesel Engine for Marine Vessels

If you’ve asked yourself, “What is the most powerful diesel engine that Cummins makes?”, the answer is simple — it’s the QSK95. Besides being the most impressive Cummins engine, it is also the most powerful high-speed diesel engine ever built for marine vessels. Manufactured with high-quality Cummins parts, this V-16 cylinder 4-stroke diesel engine offers 3,200 to 4,200 horsepower and 15,462 to 17,802 pound-feet torque.

To give you an idea of how strong the QSK95 is, consider that the horsepower of this one Cummins engine is equivalent to the sum horsepower of 25 passenger cars. Additionally, a single unit could put out enough power for over 1,500 homes when used as a power generator.

Alongside being the most powerful diesel engine ever constructed for marine vessels, the QSK95 offers a wide range of benefits compared to medium-speed engines. For example, the QSK95 offers cost-effective rebuilds and easier installation of marine engine parts due to the compactness of the engine. Compared to medium-speed engines, it also offers lower capital costs.

The heart of the QSK95 is designed for incredible strength. With immense power backing it up, the power cylinder can reach impressive levels of peak cylinder pressure. As a result of the higher cylinder pressure, the engine has enhanced combustion, allowing it to reduce fuel consumption and meet the strictest of emissions regulations.

You can trust the Cummins QSK95 to last for a long time and reliably provide power to your vessel. Due to the engine’s externally mounted key components, it’s easy for mechanics to access and repair Cummins engine parts, leading to faster maintenance services. This engine is so durable that you can expect it to provide an incredibly long life-to-overhaul cycle, even when consistently placed in severe-duty conditions.

 

Maximized Power With Minimal Environmental Footprint

As Cummins’ biggest diesel engine, the QSK95 comes with strength at its core. More power doesn’t always mean less fuel efficiency; the QSK95‘s clean combustion and efficient fuel injection system allows it to meet International Maritime Organization (IMO) Tier 2 and Environmental Protection Agency (EPA) Tier 3 emissions standards. For marine applications, the 4,000 horsepower marine engine utilizes exhaust after-treatment systems from Cummins to attain EPA Tier 4 emissions standards.

Cummins also makes the QSK95 marine engine with future-thinking environmental stewardship in mind. It’s constructed for zero disposal impact, meeting Green Passport standards. Additionally, the QSK95 replaces the need for lube oil filters with an ELIMINATOR™ oil filtration system. It incorporates on-engine fuel filter replacement cartridges that are much more affordable and easy to dispose of and maintain.

Due to the engine’s reduced fuel consumption, users save money on operating costs, and the engine has a more significant environmental impact. By lowering fuel usage, the QSK95 has become one of the most environmentally sustainable Cummins engines out there.

 

Cummins QSK95 Features

Besides the exceptional power, a Cummins QSK95 engine comes with numerous features that make it one of the most impressive overall engines today. If you’re interested in purchasing the QSK95, check out some of its primary components made with high-quality Cummins marine engine parts:

Fuel system: The QSK95 comes with a High-Pressure Common Rail Fuel System designed to provide the engine with high injection pressure, going up to 2,500 bar. High pressure comes with several benefits, such as lower emissions, greater low-end torque, idle stability and quiet operation. The fuel system also has NanoNet™ filtration, which prevents fuel contamination.

Cooling system: The cooling system features a titanium plate heat exchanger, requiring little maintenance and offering exceptional durability. It also has a two-pump, two-loop system that uses a dual impeller and a single shaft pump that boasts high-quality sealing technology.

Exhaust system: The QSK95 has a dry shielded exhaust manifest, providing superior performance and reduced fuel consumption.

Air system: Every QSK95 comes with two-stage aftercooling to improve performance and operational efficiency. It also has Cummins turbochargers designed for marine applications.

Lubrication system: Instead of using spin-on filters, the lubrication features the ELIMINATOR™ self-cleaning oil filtration system, which lowers costs and reduces time spent on maintenance. The engine also has a pre-lube starter to protect it from damage coming from dry starts.

Electronics: The engine’s 24-volt electronics use proven Electronic Control Modules (ECM) technology from Cummins to track operating parameters. They also come with prognostics, complete engine protection and diagnostics. A customer favorite is the customer interface box containing all the vessel connections. Having this piece of equipment with all Cummins electric parts makes it much easier to install the engine properly.

Certifications: For emissions-conscious buyers, the engine’s compliance with IMO Tier 2 emissions regulations is a significant draw. The QSK95 also meets requirements from the International Convention for the Safety of Life at Sea (SOLAS) and the International Association of Classification Societies (IACS).

Optional equipment: Interested in customizing the engine with Cummins parts? You can add Cummins marine parts such as turbine air starters, an SAE B accessory drive and a fully integrated type approved safety and alarm system. You can also select front power take-off up to 80% rated power and C Command monitoring and display panels.

 

Current Cummins QSK95 Marine Uses

One of the primary applications for the QSK95 is powering tugboats. These tugboats play an essential role in maritime transport and the world economy. Ships that transport products and raw materials across the seas account for 90% of the world’s trade. The large cargo ships that do most of this transportation require tugboats to help them dock in port.

As you might expect, the tugboats assisting these ships have to be powerful. The Cummins QSK95 is a perfect fit for this application, as the engine gives these boats the strength they need to pull large cargo ships and help them dock safely. Tugboats with QSK95 engines are already being used in Ghana, helping to keep the country’s economy afloat.

Another QSK95 Cummins marine use includes its installation in recreational marine vessels, such as superyachts and ships designed to support yachts. You may also find the engine utilized in passenger ferries and crew boats.
