American technology in engine and hull design is largely responsible for the plentiful interest in American boating.

Actually, the engine displacement formula is the standard formula for computing the volume of a cylinder of any type with an added factor that represents the number of cylinders in the engine.

To determine car speed for a given combination of engine speed, gear ratio, and tire size, the formula is: Af.

To determine engine speed for a given combination of the other three factors the formula is: Af.

The thermostat is important to get your engine up to operating temperature quickly, and to keep it running at its most efficient temperature through the proper circulation of the coolant.

This is why a high compression engine requires fuels specially formulated to not self-ignite ( which would cause engine knocking when operated under these conditions of temperature and pressure ), or that a supercharger and intercooler to provide a lower temperature at the same pressure would be advantageous.

A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine.

He is the author of KnightCap, a reinforcement-learning based chess engine.

* 1885 – Gottlieb Daimler is granted a German patent for his engine design.

With capacity to produce up to 5, 000 engines a year by 100 specially trained personnel, like traditional Aston Martin engine production from Newport Pagnell, assembly of each unit is entrusted to a single technician from a pool of 30, with V8 and V12 variants assembled in under 20 hours.

The mental ray engine was included in rendering and therefore it is possible to do quality renderings.

They may notice a distinctive noise from its engine or the number of vapour trails it is leaving.

The town centre is a principal engine of economic revival not only for all communities across the Borough, but also for Pennine Lancashire.

Incandescent and xenon light sources require the vehicle ’ s engine to continue running to ensure that the battery is not depleted when the lights are used for a prolonged period.

Beechcraft is an American manufacturer of general aviation and military aircraft, ranging from light single engine aircraft to business jets and light military transports.

A SAT-solving engine is now considered to be an essential component in the EDA toolbox.

Sogou Pinyin is a popular Chinese Pinyin input method editor developed by Sogou, a Chinese search engine.

A Carnot heat engine is a hypothetical engine that operates on the reversible Carnot cycle.

The expected increase of fuel efficiency of the engine ( caused by the higher temperature, as shown by Carnot's theorem ) could not be verified experimentally ; it was found that the heat transfer on the hot ceramic cylinder walls is higher than the transfer to a cooler metal wall.

Clutches are used whenever the transmission of power or motion needs to be controlled either in amount or over time ( e. g., electric screwdrivers limit how much torque is transmitted through use of a clutch ; clutches control whether automobiles transmit engine power to the wheels ).

A centrifugal clutch is used in some vehicles ( e. g., Mopeds ) and also in other applications where the speed of the engine defines the state of the clutch, for example, in a chainsaw.

In the case of a chainsaw this allows the chain to remain stationary whilst the engine is idling ; once the throttle is pressed and the engine speed rises, the centrifugal clutch engages and the cutting chain moves.

Based on its success, Raven Software and Activision later published Soldier of Fortune II: Double Helix in 2002, based on the Quake III: Team Arena engine.

The first known radial-configuration engine to ever use a twin-row design was the 160 hp Gnôme " Double Lambda " rotary engine of 1912, designed as a 14-cylinder twin-row version of the firm's 80 hp Lambda single-row seven-cylinder rotary, with only the German Oberursel U. III clone of the Double Lambda reproducing the Gnome Double Lambda's twin-row design before the end of World War I.

The DFV design used a similar cylinder head to the one Duckworth had prototyped on the four-cylinder FVA units on a custom Cosworth cylinder block and crankcase, forming a single 90 ° V8 engine, thus creating a legend in its own right, the DFV-literally meaning " Double Four Valve ".

Despite possessing, this engine could not be turbo-supercharged and Republic finally modified the design again, this time to accommodate the enormous Pratt & Whitney R-2800 Double Wasp engine, which produced.

Unfortunately, the aircraft was capable of carrying no more fuel than the P-43, and the Double Wasp engine was far more thirsty, significantly limiting the aircraft's range.

Britain refused to supply the Armstrong Siddeley Double Mamba engine originally selected and the design was altered to accept a mid-mounted 2200 hp Wright engine instead as used in the Lockheed Constellation, which necessitated a redesign of the transmission due to the increase in weight and vibration.

Double clutching, although time consuming, eases gear selection when an extended delay or variance exists between engine and transmission speeds.

Double clutching occurs if the clutch pedal is released while matching engine speeds in neutral and again engaged prior to shifting into the next gear.

This complexity was referenced early in Chrysler's development of their 1950s hemi engine: the head was referred to in company advertising as the Double Rocker head.

He planned to use the new 2, 000 hp Pratt & Whitney Double Wasp XR-2800-21, eighteen cylinder, two-row radial engine, which was the largest and most powerful aircraft engine ever developed in the United States. 2 The new design would incorporate eight 0. 50 inch machine guns, additional ammunition, increased fuel capacity and armor protection for the pilot.

| engine ( prop )= Pratt & Whitney R-2800-6 Double Wasp

| engine ( prop )= Pratt & Whitney R-2800-10W " Double Wasp "

Double clutching is easier to get smooth, as speeds that are close but not quite matched need to speed up or slow down only transmission parts, whereas with the clutch engaged to the engine, mismatched speeds are fighting the rotational inertia and power of the engine.

* Arthur Woolf, English engineer, best known for invention of a compound steam engine.

The second volume covered the development of high pressure steam and the simple expansion steam engine from 1800, by Trevithick and Woolf.

Woolf became the leading Cornish steam engineer and his designs were adopted by all the engine designers of the day.
