The Cummins NH220 engine model is well-known among heavy machinery users, but there are still a few other types of Cummins NH engines to note.
NH
The NH Cummins engine is the predecessor model of the NH Cummins 220. It is the same basic design as the NH220, just with slightly less horsepower. There are some similarities in the way the engine runs, the maintenance it requires, and the vehicles that typically use it.
NH Cummins 250
The NH Cummins 250 has a larger horsepower capacity than the NH220. This naturally gives it a bigger capacity for a few extra jobs. However, the NH Cummins 250 engine does share some traits with the NH220 model. For example, it has the same typical rebuild cost range. Many customers will choose the NH220 instead of the 250 model because the 220 is available in larger quantities.
NTA
The NTA engine model is a bit more advanced than the previous two models. It offers a range of 310 to 540 horsepower for users to choose from. Aside from the higher horsepower capacity, the NTA engine also has fully electronic fuel management. The overall design is more efficient and user-friendly.
ISL
The ISL is another model that has a higher horsepower capacity than the Cummins NH220 engine. It has a more advanced design and some other features that give it a smooth ride. Other models, such as the ISM, can offer up to 500 horsepower.
The Cummins NH 220 engine has a 6-cylinder design with a typical overall length of 1,165 mm, a width of 872 mm, and a height of 961 mm. Its net power output is 162 kW (220 hp). The NH Cummins engine net torque is 637 Nm, and its compression ratio is 17:1. Engine speed (rpm) is an important feature, and for Cummins NH 220, it ranges from 1,800 to 2,200 rpm. The 6-cylinder engine can have a fuel consumption rate of 45.4 liters per 100 kilometers. Some derivatives may have intercoolers for greater efficiency.
Cummins NH 220 engine maintenance involves the following procedures. Check the oil level every five days and top up as necessary. Change the engine oil and oil filter after 10,000 kilometers. Replacement of the fuel filter element is due after 20,000 kilometers. Check the coolant level, and if it is found lacking, the recommended mixture of ethylene glycol and water should be sourced as per the manual. An NH 220 should be flushed every two years (or 100,000 km) to avoid the accumulation of scale. Check air filter elements every 10,000 kilometers and clean if they are reusable. Replace the brake shoes after the vehicles run 20,000 km. Regularly check the hydraulic system and work to correct any leakage.
Few industry machinery models are as popular as the Cummins NH220 engine.
Heavy-duty trucks and buses:
The Cummins NH220 engine shines in the realm of heavy-duty trucks and buses. Its robust architecture and high-torque induction make it the star for transporting massive loads across great distances or tackling tough terrains. The NH Cummins engine isn't just about raw power; fuel efficiency is a top priority, especially for long-haul trucking. Advanced fuel systems ensure buses and trucks sip diesel intelligently, extending journey ranges. Heavy-duty vehicles aren't just about strength; they must haul tons without breaking down. Durability reigns supreme, and the NH220's proven track record stands strong, minimizing time off the road for repairs.
Construction and mining equipment:
In the demanding world of construction and mining, machinery needs an iron heart to guarantee unwavering performance throughout long work shifts. Tasks range from foundational excavations and aggregative demolitions to the extraction of valuable earth materials deep within the land's bowels. Powering this vast array of heavyweight champions—bulldozers, excavators, loaders, and haul trucks—are engines that exemplify rugged endurance, high torque output, and exceptional fuel economy. The operators of these machines expect a tireless ally by their side, a workhorse that never falters, allowing them to conquer any challenge with certainty and peace of mind.
The NH220 engine performs exceptionally well in construction and mining machinery. Its high-torque output matches the complex terrain of mining operations. Fuel efficiency may also ensure timely completion. This makes it a popular choice in the construction and mining industry.
Agricultural machinery:
In today's agriculture, machines need dependable engines that can handle tough jobs while using fuel wisely. High-torque output is vital for farm tractors, harvesters, and tillers working in diverse soil conditions and terrains. These durable engines also help farmers and agribusiness managers maximize field time and operational efficiency.
The NH220 Cummins engine showcases its flexibility in the agricultural sector. Whether powering a tractor in farmlands or a harvester in fields, its high torque handles varying soil states. Advanced fuel systems ensureoptimal use, promoting agribusiness efficiency.
Opting for the right Cummins NH220 engine requires careful consideration of various factors. It's not just about matching it to a vehicle but ensuring it fulfills business needs, operational efficiency, and safety standards.
Application needs
It's vital to identify specific usage situations such as whether the engine will power heavy-duty trucks, construction machinery like excavators, loaders, or high-density fishing boats. There's a diverse range of NH 220 engines tailored for distinct applications. For instance, while some versions are optimized for road vehicles with particular torque and weight capacity considerations, others might have adaptations suited for marine conditions.
Power output and torque
Understand the jobs that need to be done. It will be necessary to think about factors like the weight of things to be transported, distances, and types of roads. Choosing an engine that provides the necessary power and twist for smooth operations without overworking it is essential to ensure long-term use.
Fuel system
Consider the vehicle's requirements, the types of fuel available, and the focus on cost-effectiveness. Opting for a mechanically injected engine might be simpler and more affordable, while electronically injected models can provide better mileage and performance but may require more advanced maintenance.
Availability of parts
When selecting an NH 220 engine, it's wise to consider the accessibility of spare parts for future repairs and maintenance. Investigating the availability of crucial components such as fuel pumps, injectors, turbochargers, and electronic control units can save time and expenses in the long run. Opting for models with widely distributed replacement parts can ensure smooth servicing and minimize downtime.
Q1: What does NH stand for in the Cummins NH engine?
A1: The Cummins NH engine model is referred to as the HS followed by a number. The NH stands for New Hudson, named after the Hudson Motor Car Company, which was a part of the early years of Cummins Engine Company.
Q2: Is the Cummins NH engine a good choice for all applications?
A2: While the Cummins NH220 engine is undoubtedly robust, it's essential to recognize that different applications might have varying requirements. Some might benefit more from the capabilities of the Cummins NH325 horsepower engine or other models like the NH150, NH180, and NH250 horsepower engines.
Q3: What are some notable features of the NH Cummins engine?
A3: The NH Cummins engines are well-known for their diesel turbo engines, high-performance output, strong load capacity, long usage period, and low failure rate.
Q4: What is the mean time between failure of the NH220 engine?
A4: One of the critical performance indicators of an engine is its mean time between failure (MTBF). The NH Cummins engine boasts a remarkable MTBF, ensuring that users experience fewer interruptions and enjoy prolonged operational efficiency.
