geared turbofan jet engine from pratt & whitney
Pratt & Whitney PW1000G The Pratt & Whitney PW1000G is a high-bypass geared turbofan engine family, currently selected as the exclusive engine for the Bombardier CSeries, Mitsubishi Regional Jet (MRJ), and Embraer's second generation E-Jets, and as an option on the Irkut MC-21 and Airbus A320neo. The project was previously known as the Geared Turbofan (GTF), and originally the Advanced Technology Fan Integrator (ATFI). The engine is expected to deliver reductions in fuel use and ground noise when used in next-generation aircraft. The PW1000G engine first entered commercial use in January 2016 with Lufthansa's first commercial Airbus A320neo flight.[3]
Monster Energy NASCAR Cup Series The cars are powered by EFI V8 engines with compacted graphite iron blocks and pushrod valvetrains actuating two-valves per cylinder, and are limited to 358 cubic inches' (about 5.8 liters) displacement. However, modern technology has allowed power outputs near 900 horsepower (670 kW) in unrestricted form while retaining the conventional basic engine design. In fact, before NASCAR instituted the gear rule, Cup engines were capable of operating more than 10,000 rpm.[31] A NASCAR Cup Series engine with the maximum bore of 4.185 inches (106.3 millimeters) and stroke of 3.25 inches (82.55 millimeters) at 9,000 rpm has a mean piston speed of 80.44 fps (24.75 m/s). Contemporary Cup engines run 9,800 rpm, 87.59 fps (26.95 m/s), at the road course events on Pocono Pennsylvania's long front stretch and at the .526-mile short-track Martinsville Speedway. At the backbone 1.5- to 2.0-mile tri-oval tracks of NASCAR, the engines produce over 850 hp running 92–9400 rpm for 500 miles, 600 mi for the Coca-Cola 600 Charlotte race.
