What is renewable natural gas? Renewable natural gas (RNG) differs from fossil fuels as it's produced from various types of waste, like used cooking oil, animal waste, sludge from wastewater, manure and other waste materials. As these biodegradable materials decompose, methane is released. This methane is captured and converted into RNG. Because methane is the primary component o
An engine's performance depends on both the parts you can see and the technology that you cannot. That's where the Electronic Control Module (ECM) comes in. The ECM is the brain of the engine, optimizing performance and efficiency while managing key safety and operational systems in both on-highway and off-highway vehicles. This article explains the functions of the ECM and how it optimiz
Today, more companies are investing in low carbon solutions across the power generation and industrial markets, including mining marine and rail. These solutions include battery-electric and fuel-cell battery hybrid systems as well as internal combustion engines (ICEs) powered by hydrogen. Cummins Inc. has brought to market battery-electric and fuel-cell hybrid platforms as well as electr
Before a turbocharger is ready to be installed in an engine, it needs to be tested to ensure it works properly with no defects. There are two main methods for turbocharger testing: cold testing and hot testing. This article examines the differences between these testing methods and the advantages of cold testing. As companies search for ways to operate more sustainably, cold testing has emerged as
Hydrotreated vegetable oil (HVO) is a biofuel produced from vegetable oils and animal fats. It is often referred to as HVO, or as renewable diesel, and is distinct from biodiesel. A major benefit of HVO is that it can be used as a drop-in replacement for traditional diesel with no engine modification. It is an ideal option to reduce the emissions of motor vehicles in a simple and cost-effective wa
Alternative solutions to maximize power and reduce emissions Which energy solutions provide the ideal combination of maximum power performance that enhances efficiency while also minimizing or eliminating emissions? The right answer for a company’s power needs depends, of course, on the application, the company’s access to lower carbon options and the budget at their disposal. There
The energy transition in transportation is happening now. Businesses are under pressure to meet new regulations, environmental targets and public opinion. Fleets looking to act quickly to implement clean solutions are turning to compressed natural gas engines. They’re an increasingly popular choice for fleets looking to save money on fuel while improving air quality and reducing their total emissi
Switching to natural gas vehicles (NGVs) can be a great way for commercial vehicle fleets to save money. With lower fuel expenses and reduced maintenance costs on after-treatment systems, natural gas is an attractive and economical fuel choice for many applications. With over 30 years of experience designing and manufacturing natural gas engines for truck and bus applications, Cummins is the perfe
A more sustainable world is one with lower emissions. By lowering greenhouse gases (GHGs) — like carbon dioxide (CO2) and methane (CH4), which contribute to climate change; and oxides of nitrogen (NOx ), which contribute to ozone depletion; and particulate matter (PM), which impacts air quality — we can improve the resiliency of our lives. Decarbonizing with renewable energy and adopting
After building its 5 millionth engine, Cummins Inc.’s Rocky Mount Engine Plant (RMEP) is continuing its long history of innovation in engine technology and manufacturing. The next stop? Building fuel-agnostic engines in their VPI Lab. What is the VPI Lab? VPI, or value package introduction, is Cummins’ process for commercializing technology for market through the definition, design, de
This article explores the importance of reducing transportation emissions, the concept of carbon footprints, and the various strategies employed to combat climate change and achieve a net-zero future. Why is it important to reduce emissions? Greenhouse gases (GHG) are molecules that accumulate in the atmosphere and lead to global warming. GHG emissions mitigation is the act of reducing the a
As the world seeks sustainable alternatives to traditional energy sources, understanding the concepts of clean and renewable energy is crucial. Let us discover the benefits of clean energy sources like solar or wind. We will also take a look at the top clean energy fuels such as hydrogen and RNG, and Cummins Inc.’s commitment to driving innovation in the clean energy space. What is the di
