The Reher-Morrison-Shepherd team won NHRA's Division 4 Modified championship in 1973, [3] and took a class win at the 1974 Winternationals in a pumpkin orange Chevrolet-powered F/Gas [citation needed] Ford Maverick. [4] Shepherd ran back-to-back 10.67s to defeat John Smith’s M/Gas Volkswagen and defending event champion Bob Riffle’s C/Gas ...
A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage . The name difference engine is derived from the method of finite differences , a way to interpolate or tabulate functions by using a small set of polynomial co-efficients.
A dry-sump engine requires a pressure relief valve to regulate negative pressure inside the engine, so internal seals are not inverted. Dry-sumps are common on larger diesel engines such as those used in ships, as well as gasoline engines used in racing cars, aerobatic aircraft, high-performance personal watercraft and motorcycles.
The thrust-to-weight ratio is calculated by dividing the thrust (in SI units – in newtons) by the weight (in newtons) of the engine or vehicle.The weight (N) is calculated by multiplying the mass in kilograms (kg) by the acceleration due to gravity (m/s 2).
In petrol (gasoline) engines used in passenger cars for the past 20 years, compression ratios have typically been between 8:1 and 12:1. Several production engines have used higher compression ratios, including: Cars built from 1955 to 1972 which were designed for high-octane leaded gasoline, which allowed compression ratios up to 13:1.
GE GEVO-12, 12-cylinder engine used in locomotives, such as the GE ES30ACi, GE ES44AC, [6] GE ES43ACi, GE ES43ACmi, 3TE25K2M and MPI HSP46 Diesel Locomotives; GE GEVO-16, 16-cylinder engine used in locomotives, such as the GE ES59ACi, [6] GE ES58ACi, [6] GE ES57ACi Diesel Locomotives. HDL series [1] GE 7HDL-16, 16-cylinder engine used in only ...
The comptometer-type calculator was the first machine to receive an all-electronic calculator engine in 1961 (the ANITA mark VII released by Sumlock comptometer of the UK). In 1890 W. T. Odhner got the rights to manufacture his calculator back from Königsberger & C , which had held them since it was first patented in 1878, but had not really ...
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
