Since the 1960s, composite airframes and quieter, more efficient engines have become available, and Concorde provided supersonic passenger service for more than two decades, but the most important lasting innovations have taken place in instrumentation and control.

Due to engine knocking ( detonation ), the compression ratio in a gasoline or petrol-powered engine will usually not be much higher than 10: 1, although some production automotive engines built for high-performance from 1955 – 1972 had compression ratios as high as 13. 0: 1, which could run safely on the high-octane leaded gasoline then available.

Larger diesel engines are still often used in trucks and heavy machinery, although they require special machining not available in most factories.

One can measure the entropy of a system to determine the energy not available for work in a thermodynamic process, such as energy conversion, engines, or machines.

The application of steam engines to powering cotton mills and ironworks enabled these to be built in places that were most convenient because other resources were available, rather than where there was water to power a watermill.

The design was hampered by the necessity to use reciprocating engines instead of the smaller turbines, since no sufficiently powerful design was available and acceptable to the German navy.

The 2108-2109 models were in production until 2001, when they were restyled with new side panels, interiors and 1. 5 L fuel injection engines ( though fuel injection was available as early as 1995 ).

These models are basically based on Samara technology with a new body and fuel injection engines as standard features, though carburated versions have also been available up until 2001.

As automakers were switching en masse from carbureted to fuel injected engines during the early to mid-1980s, the detergent additives that existed in most available gasolines proved not to be enough to prevent injection clogging, leading to drivability problems, Mobil received accolades from General Motors and other automakers for increasing the detergency of its Super Unleaded gasoline in 1984 to prevent formation or deposit build-ups of the injectors but also remove existing deposits as well in normal driving.

The Chevrolet Astro, the last surviving rear-wheel-drive mid-size van, was popular for towing applications because of its available 4. 3-liter V6, and some owners even installed their own V8 engines.

The use of ignition magnetos is now confined mainly to engines where there is no available electrical supply, for example in lawnmowers and chainsaws.

It is also widely used in aviation piston engines even though an electrical supply is usually available.

Open-wheel vehicles, due to their light weight, aerodynamic capabilities, and powerful engines, are often considered the fastest racing vehicles available and among the most challenging to master.

Also in 1957, Chevrolet sold enough of their new fuel injected engines to the public in order to make them available for racing ( and Ford began selling superchargers as an option ), but Bill France immediately banned fuel injection and superchargers from NASCAR before they could race.

Very efficient ( hence complex and sophisticated ) main engines were required to fit within the available vehicle space.

The only exceptions to this are Volvo and its subsidiary Mack Trucks, which are available with their own engines.

Given the current size of the Web, even large search engines cover only a portion of the publicly available part.

The time available for fuel to be port-injected into a Wankel engine is significantly shorter than that of four-stroke piston engines due to the way the three chambers rotate.

Also, the thrust levels available from typically used arcjet engines are very low compared with chemical engines.

Later versions could be equipped with engines of 1 and 1. 3 litres, and superchargers were also available.

TTS engines with different languages, dialects and specialized vocabularies are available through third-party publishers.

Dodge chose not use the full model lines and engines available to them, the 2. 7L V6 being available in the Journey and Avenger instead of the 3. 2 in the North American versions.

Depending upon the OS version, WSH and the default script engines ( VBScript and JScript ) are available.

Starting with the Wolfenstein 3D franchise and continuing with the Doom and Quake series, Id pushed the boundaries of video game technology — particularly 3D computer graphics technology — and creates game engines that are heavily used throughout the video game industry.

Wisely, the company had not totally turned its back on piston engines, as it continued to produce a variety of four-cylinder models throughout the 1970s.

The gasflow in most turbines employed in gas turbine engines remains subsonic throughout the expansion process.

The Soviet Union studied nuclear engines for their own moon rockets, notably upper stages of the N-1, although they never entered an extensive testing program like the one the U. S. conducted throughout the 1960s at the Nevada Test Site.

In Brazil, the Type 1 never received electronic fuel injection, instead retaining carburetors ( one or two one-barrels ) throughout its entire life, although the carburetion differs from engines of different years and specification.

Surveyor 3 was the first spacecraft to unintentionally liftoff from the Moon's surface, which it did twice, due to an anomaly with Surveyor's Landing Radar which did not shut off the vernier engines but kept them firing throughout the first touchdown, and after it.

By this point, the company's engines and licensed designs were used worldwide throughout the industry.

Most of these older fire engines can be seen at various fire stations throughout Griffith or in Fourth of July parades to this day.

Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines, starting in the early 18th century.

This was used to pump water for the Kennet and Avon Canal ; on certain weekends throughout the year the modern pumps are switched off and the two steam engines at Crofton still perform this function.

A fire department is normally set up where it can have fire stations and sophisticated fire apparatus strategically deployed throughout the area under its control so that dispatchers can send fire engines, fire trucks, or ambulances from the fire stations closest to the incident.

As a result, conventional infrastructure and transport systems, which are fitted to combustion engines, remain prominent throughout the globe.

By 1830 there were 32 steam engines in cotton mills throughout the rapidly expanding town, an example of which, originally installed at Harle Syke Mill, is on display in the Science Museum ( London ).

Alfa Romeo has produced many successful hemi-head engines throughout the years.

Piston engines on airplanes required a great deal of attention throughout the flight with their multitude of gauges and indicators.

The building itself incorporated modern design principles to encourage adequate ventilation, used electric clocks throughout, contained only the second internal phone installation in the U. K. at the time, and generated its own power through the use of diesel engines.

Steam fairs are held throughout the year in the UK, and in other countries, where visitors can experience working traction engines at close hand.

The class was distributed throughout the British Railways system, but the significant decline in the traffic for which they were designed resulted in a large surplus of shunting engines on the network.

Unlike ramjet or scramjet engines the design is able to provide high thrust from zero speed up to Mach 5. 5, with excellent thrust over the entire flight, from the ground to very high altitude, with high efficiency throughout.

Beginning with the 1963 model year, the " Jet Thrust " R-series V-8 engines designed for the Avanti could be ordered throughout the Studebaker line, with the naturally aspirated R1 delivering, the supercharged R2 giving and the limited-production supercharged 304. 5 in³ ( 5. 0 L ) R3 powerplant issuing forth a full.

Steam engines were made throughout most the company's history.

Air-cooled engines became popular throughout Europe.

The Royal Classic was factory fitted with a turbocharged 13B Rotary or 2. 0 Litre V6 engines, electric leather seats, digital speedometer, a cool-box for canned beverages, prominent emblems, electronically adjustable suspension and power options throughout.

Physics engines are used throughout the video game and movie industry, but not all physics engines are alike ; They are generally broken into real-time and the high precision but these are not the only options.
