Commercial vehicle fleet managers face a dizzying array of options when it is time to replace or upgrade vehicles.

When it comes to natural gas engines, there are a range of frequently asked questions about the cost, practicality, and feasibility of integrating natural gas into commercial fleets.

Long after a purchase order is signed, a wide range of decisions and operating conditions influence total cost of ownership (TCO) over the life of an engine.

What is the fuel delivery system? The fuel delivery system is one of the most critical components in a vehicle and is the heart of a vehicle's power generation process.

Global pressure on mining's carbon footprint has never been higher, despite the backdrop of innovation fatigue.

Advanced diesel engines are some of the most fuel and energy-efficient options in the market, but those are just the beginning of their advantages.

The diesel engine working principle was completed by the inventor, Rudolf Diesel, in 1892, and the first prototype was created in 1897.

Rudolf Diesel and Clessie Cummins have many things in common.

Mining has a unique way of exposing the weaknesses of new technology.

A simplified aftertreatment system on Cummins’ natural gas engines offers strong uptime and no routine maintenance in a lightweight package, and it has improved further.

When drivers choose a RAM heavy-duty pickup truck, they expect strength, durability and dependable performance.

Four trucks. Seven cities. One goal: put Cummins' powertrains in the hands of the people who use them every day.

Summary Natural gas engines offer lower operating costs and reduced emissions compared to diesel, and their simpler, maintenance-free exhaust treatment system eliminates the filter changes and replacements that diesel engines require.

Summary Natural gas engines have emerged as a strong alternative to diesel for heavy-duty commercial fleets, offering quieter operation, simpler maintenance, more convenient refueling options, and consistently lower, more stable fuel costs.

Today’s medium-duty fleets are faced with a growing demand to deliver high performance while lowering environmental impact.

Low and stable natural gas prices continue to draw attention from fleets and owner-operators looking to reduce operating costs while lowering emissions.

Maximizing fluid economy in a heavy-duty diesel powertrain begins long before a new truck delivers its first load.

Summary Diesel powertrains and battery electric powertrains each offer distinct advantages depending on the application.
