Two Top Fuel dragsters side by side during an NHRA event in 2012. Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 341.68 miles per hour (549.9 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.61 seconds.
Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.
Nitrous cars use high octane racing gasoline as fuel while supercharged and turbo cars use methanol as fuel. These engines put out an extremely large amount of horsepower, some at approximately 2500 to upwards of 4000 H.P. The engines propel the cars down the track at speeds of over 250 mph.The exhaust system is
The EPA rated the Nissan Leaf electric car with a combined fuel economy of 99 MPGe, [9] and rated the Chevrolet Volt plug-in hybrid with a combined fuel economy of 93 MPGe in all-electric mode, 37 MPG when operating with gasoline only, and an overall fuel economy rating of 60 mpg-US (3.9 L/100 km) combining power from electricity and gasoline.
A nitro engine generally refers to an engine powered with a fuel that contains some portion (usually between 10% and 40%) of nitromethane mixed with methanol.Nitromethane is a highly combustible substance that is generally only used in very specifically designed engines found in Top Fuel drag racing and in miniature internal combustion engines in radio control, control line and free flight ...
An early example, a 1958 Fuel rail, on display at the California Automobile Museum. A dragster is a specialized competition automobile used in drag racing. Dragsters, also commonly called "diggers", can be broadly placed in three categories, based on the fuel they use: gasoline, methanol, and nitromethane. They are most commonly single-engined ...
Richard Hartman, a crew chief for NHRA Funny Car driver Tim Wilkerson, rebodied a former Wilkerson Funny Car chassis into an Altered, reaching 4.92 seconds in the quarter-mile with a terminal velocity of 304.53 MPH. [22] It is the fastest quarter-mile car currently in the NHRA, as Top Fuel and Funny Car both run only to 1,000 feet.
At higher speeds, wind resistance plays an increasing role in reducing fuel economy in automobiles. At 60km/h, the global average speed, energy loss due to air drag in fossil fuel cars is approximately 5% of the total energy loss. Friction (33%), exhaust (29%), and cooling the engine (33%) account for the rest. [12]
