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. The fuel delivery system serves a similar function to a fuel tank in diesel-powered vehicles. However, the fuel delivery system is specifically designed to handle gaseous fuels like hydrogen and natural gas, both of which are
As the automotive industry navigates the complexities of the energy transition, vehicle software is emerging as a key component in transforming how OEMs operate and innovate. The sophistication of vehicle software components can bring new capabilities and create a higher level of efficiency and safety. This article looks at the different facets of vehicle software’s role in the energy transition a
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
