While most oil companies were switching to leaded gasolines en masse during the mid-to-late 1920s, American Oil chose to continue marketing its premium-grade " Amoco-Gas " ( later Amoco Super-Premium ) as a lead-free gasoline by using aromatics rather than tetraethyllead to increase octane levels, decades before the environmental movement of the early 1970s led to more stringent auto emission controls which ultimately mandated the universal phase out of leaded gasoline.

While glow engines run on special and expensive hobby fuel, gasoline runs on the same fuel that powers cars, lawnmowers, weed whackers etc.

While the piston is close to Top Dead Center, the compressed air – fuel mixture in a gasoline engine is ignited, usually by a spark plug, or fuel is injected into the diesel engine, which ignites due to the heat generated in the air during the compression stroke.

While exporting crude oil, Mexico imports expensive gasoline.

While primarily utilised for ceremonial purposes, the regiment can be deployed for internal security or police roles if required.

The internal level, which is hidden inside the DBMS and depends on its implementation ( see Implementation section below ), requires a different level of detail and uses its own data structure types, typically different in nature from the structures of the external and conceptual levels which are exposed to DBMS users ( e. g., the data models above ): While the external and conceptual levels are focused on and serve DBMS users, the concern of the internal level is effective implementation details.

While the conceptual and external levels design can usually be done independently of any DBMS ( DBMS-independent design software packages exist, possibly with interfaces to some specific popular DBMSs ), the internal level design highly relies on the capabilities and internal data structure of the specific DBMS utilized ( see the Implementation section below ).

While the resource inputs are generally controlled by external processes like climate and parent material, the availability of these resources within the ecosystem is controlled by internal factors like decomposition, root competition or shading.

While the resource inputs are generally controlled by external processes like climate and parent material, the availability of these resources within the ecosystem is controlled by internal factors like decomposition, root competition or shading.

While the real values of the specific economic items generally stay the same in terms of relatively stable foreign currencies, in hyperinflationary conditions the general price level within a specific economy increases rapidly as the functional or internal currency, as opposed to a foreign currency.

While there have been and still are many stationary applications, the real strength of internal combustion engines is in mobile applications and they dominate as a power supply for cars, aircraft, and boats.

While the tiny gap between cylinder and barrel on most revolvers is insignificant to the internal ballistics, the seal is especially effective when used with a suppressor, and a number of suppressed Nagant revolvers have been used since its invention.

While there are still some places in the world where sail-powered passenger, fishing and trading vessels are used, these craft have become rarer as internal combustion engines have become economically viable in even the poorest and most remote areas.

While the statue was closed from 1984 to 1986, the torch and a large part of the internal structure were replaced.

While the United Nations had decided not to get involved in the internal affairs of the small country, Canada thought differently and sent Alpha Flight to intervene.

While at EDF ( Électricité de France ), Abrial wrote internal notes on Z.

* While some pioneering experiments about internal structure of atoms had been made at the end of the 19th century, it was only in the 20th century that their structure was clearly understood, followed by the discovery of elementary particles.

While i5 / OS, AIX, Linux and Lotus Domino are supported on the POWER processors, Windows is supported with either single-processor internal blade servers ( IXS ) or externally linked multiple-processor servers ( IXA and iSCSI ).

While the " literary battle " against Peng raged, Mao fired Yang Shangkun – director of the Party's General Office, an organ that controlled internal communications – on a series of unsubstantiated charges, installing in his stead staunch loyalist Wang Dongxing, head of Mao's security detail.

While the marine horseshoe crabs rely on external fertilization, air-breathing chelicerates use internal but usually indirect fertilization.

While cooking, the internal pressurized steam keeps the lid tightly in place, preventing accidental removal.

While the ethnic based army was generally successful on the battlefields, they began to have negative effects on the Fatimid's internal politics, traditionally the Berber element of the army had the strongest sway over political affairs, but as the Turkish element grew more powerful they began to challenge this, and eventually by 1020 serious riots began to break out among the Black African troops who were fighting back against a Berber / Turks Alliance.

While the central Song court remained politically divided and focused upon its internal affairs, alarming new events to the north in the Liao state finally came to its attention.

While terminal marks ( i. e., full stops, exclamation marks, and question marks ) mark the end of a sentence, the comma, semicolon and colon are normally sentence internal, making them secondary boundary marks.

While this method can be effective at trapping particulates produced by combustion, it does not filter out harmful gases which may be toxic or which displace the oxygen required for survival.

While a four-stroke piston engine makes one combustion stroke per cylinder for every two rotations of the crankshaft ( that is, one-half power stroke per crankshaft rotation per cylinder ), each combustion chamber in the Wankel generates one combustion stroke per driveshaft rotation, i. e. one power stroke per rotor orbital revolution and three power strokes per rotor rotation.

While the term " spontaneous human combustion " was not yet created, Brown includes a footnote at the end of chapter 2 that suggests the phenomenon and its existence in 18th century medical studies.

While the full-scale Aerodrome was being designed and built, the internal combustion engine was contracted out to manufacturer Stephen Balzer ( 1864 – 1940 ).

While the overall reaction is a combustion, no single reaction that comprises it is a combustion reaction.

While in combustion mode the engine and motor run at the same speed.

While the overall reaction is a combustion, no single reaction that comprises it is a combustion reaction.

While PHEVs and hydrogen internal combustion engine vehicles exist, none meet this stringent standard.

Professor Jeremy P. Meyers, in the Electrochemical Society journal Interface in 2008, wrote, " While fuel cells are efficient relative to combustion engines, they are not as efficient as batteries, due primarily to the inefficiency of the oxygen reduction reaction.

While Toyota's Hybrid Synergy Drive may appear similar in that it also combines the power from a Internal combustion engine ( ICE ) and a pair of electric motor-generators ; however in its current form, Toyota uses only one planetary gearset providing only single mode functionality ( i. e. input split only ) using a series / parallel architecture.

While a combustion turbine is limited in maximum temperature by the strength of its air / water or steam-cooled rotating airfoils ; there are no rotating parts in an open-cycle MHD generator.
