LiquidPiston Inc. has developed a new engine that can run on multiple fuels, including diesel, jet fuel, and gasoline. This platform uses an optimized thermodynamic cycle and a new rotary engine architecture and could increases flight endurance over conventional UAV engines by greater than 50%.
The European Commission looks set to continue its move away from diesel, prompting manufacturers to assess future powertrain options for commercial vehicles.
The supplier revealed a range of waste heat recovery technologies for heavy-duty diesel engines at the IAA Commercial Vehicles show in Hanover, Germany, as well as variable valve timing systems, highlighting their potential to reduce fuel consumption and help reduce emissions.
48-V power is just one of many efficiency additions for the new gasoline and diesel inline sixes, along with increased use of "coasting" and cylinder deactivation.
The WLTP and other 'real-world' vehicle test cycles offer new lubrication opportunities for engine designers striving to make further improvements to power units. BP Castrol's chief engineer details what can be done.
The challenges of climate change and energy security require a continuous effort toward reduction of global environmental pollution and fossil oil consumption. To meet greenhouse gas (GHG) emission targets and to decrease oil dependency, overall energy consumption of vehicles must be substantially reduced.
In March, a new demonstrator engine by Rolls-Royce, featuring a cutting-edge lean-burn and low-emissions combustion system for future jet engine programs, began icing tests at the Global Aerospace Centre for Icing and Environmental Research in Manitoba, Canada.
An updated version of GE Aviation’s T901-GE-900 turboprop engine used in the AH-64 Apache attack and UH-60 Black Hawk utility helicopters successfully completed the preliminary design review for the U.S. Army’s Improved Turbine Engine Program.
A week prior to officially revealing its new N67 200 kVA Stage V solution installed on a genset frame concept at the Middle East Electricity show, FPT Industrial gave a sneak peek of the generator—in virtual form—to select international media at Pregnana Milanese, where about 90% of the company’s engines for power generation are produced.
Results to date show that the tiny engine also performs happily as a 666-cc twin, demonstrating potential for dynamic downsizing of the EcoBoost power unit.
All 40 cars in the world's first all-electric racing circuit run a standardized powertrain, but the uniformity ends in the 2015/2016 season when each carbon fiber/aluminum monocoque chassis FIA Formula E racecar can be fitted with a unique electric powertrain.
Cummins' Jim Trueblood says the company's Tier 4 Final program was driven by the core philosophy to utilize new or improved technologies, systems, and components that would meet the durability and reliability levels demanded for tough high horsepower applications.
Cummins Emission Solutions and Cummins Turbo Technologies took advantage of the crowd at Intermat to unveil a couple of next-generation component innovations.
