The exhaust is, however, relatively low in NOx emissions, as combustion temperatures are lower than in other engines, and also because of some inherent Exhaust Gas Recirculation-EGR-in early engines ; the higher the combustion temperature is, the higher the NOx emissions are ( sir Harry Ricardo proved in the 20's that for every 1 % increase of the proportion of exhaust gas in the admission mix, there's a 45º F reduction in flame temperature ); this allowed Mazda to meet the United States Clean Air Act of 1970 in 1973 with a simple and inexpensive ' thermal reactor ' ( an enlarged open chamber in the exhaust manifold ) by paradoxically enriching the air-fuel ratio to the point where the unburned hydrocarbons ( HC ) in the exhaust would support complete combustion in the thermal reactor ; while piston-engine cars required expensive catalytic converters to deal with both unburned hydrocarbons and NOx emissions.

* Very low toxic emissions of CO and HC due to excess air, complete combustion and no " quench " of the flame on cold surfaces

Especially the HC emissions are low on wood gas.

These emissions are hydrocarbons ( HC ), oxides of nitrogen ( NOx ), carbon monoxide ( CO ) and carbon dioxide ( CO2 ).

* Carbon monoxide ( CO ) and hydrocarbon ( HC ) pre-catalyst emissions are higher than a typical spark ignition engine, caused by incomplete oxidation ( due to the rapid combustion event and low in-cylinder temperatures ) and trapped crevice gases, respectively.

These fuels, because of their high level of purity and lack of contaminants, further enable the use of advanced emissions control equipment that has been shown to virtually eliminate HC, CO, and PM emissions from diesel vehicles.

This precludes the use of both wet sump and dry sump systems, as excess oil here would contaminate the mixture, leading to excess oil being burned in the engine and so extremely high HC emissions.

In the US, a " PAIR " air injection system reduces CO and HC emissions.

Triethylorthoformate ( HC ( OC < sub > 2 </ sub > H < sub > 5 </ sub >)< sub > 3 </ sub >) is derived, in terms of its name ( but not its synthesis ) from orthoformic acid ( HC ( OH )< sub > 3 </ sub >) and ethanol.

The HA Van was eventually supplanted by the Chevanne, but because of fleet orders, particularly from British Telecom, British Rail and the Post Office, the HA van remained in production, ultimately using the later HC Viva's engine and gearbox, incredibly until 1983.

The HC was pulled from the Canadian market after two model years amidst consumer anger over corrosion and reliability issues.

Staffordshire Bull Terriers are known to suffer from Hereditary Cataracts ( HC ) and L-2-hydroxyglutaric aciduria ( L2HGA )— a metabolic disorder resulting in behavioural changes and dementia-like symptoms — both of which are detectable via DNA tests.

Oxygen sensors are used to monitor the exhaust oxygen content before and after the catalytic converter and this information is used by the Electronic control unit to adjust the fuel injection so as to prevent the first ( NO < sub > x </ sub > reduction ) catalyst from becoming oxygen-loaded while ensuring the second ( HC and CO oxidization ) catalyst is sufficiently oxygen-saturated.

Before joining the Capitals he played for TJ VSŽ Košice ( now called HC Košice ) for four seasons from 1986-90 in Czechoslovakia.

He also translated from the English HC Lea's History of the Inquisition.

Chára was drafted 56th overall by the New York Islanders in the 1996 NHL Entry Draft from HC Sparta Praha.

Hossa was drafted in the first round, 12th overall, by the Ottawa Senators in the 1997 NHL Entry Draft from HC Dukla Trenčín of the Slovak Extraliga.

This tour was in April, and recordings from this tour are numerous, appearing on the compilations Fast Boston HC and The Early Years and the bootlegs Harmonized Noise and the Anal Cunt / Patareni split.

Starting from the Southwest and running to the Northeast the buildings are as follows ( with abbreviations in parentheses ): Benson Great Hall and Lundquist Community Life Center ( CLC ), Academic Center ( AC ), Brushaber Commons ( BC ), Clauson Fine Arts Center ( CC ), Hagstrom Student Services Center ( HC ), and Robertson Physical Education Center ( RC ).

On March 23, 2010, Daigle and HC Davos agreed to have his contract reduced from five years to three years, making him a free agent after the 2009-10 NLA season.

The Arena HC withdrew from the league on February 20, 1919 following financial difficulties.

Instead of accepting a new contract from the Oilers, Jari Kurri opted for a season in Italy and played for HC Devils Milano of the Italian Serie A. Kurri had 27 goals and 48 assists in 30 games while he played in the less competitive Italian league.

* Linköpings HC, an ice hockey team from Linköping, Sweden

* 2008: All material from 2004-2007 is updated and printed in the Official Handbook of the Marvel Universe A-Z Premiere HC set, divided into 12 volumes ( each containing 240 pages ).

It shares certain features with other Sturm und Drang symphonies of this time, and is likely inspired from Joseph Haydn's Symphony No. 39 which is likewise in G minor .< ref > HC Robbins Landon, < u > Haydn: Chronicle and Works </ u >, 5 vols, ( Bloomington and London: Indiana University Press, 1976 -) v. 2, < u > Haydn at Eszterhaza, 1766-1790 </ u ></ ref >

One of his sons was killed at Isandhlwana ; of the other sons HC Shepstone ( b. 1840 ) was secretary for native affairs in Natal from 1884 to 1893 ; Theophilus was adviser to the Swazis ( 1887-1891 ); and AJ Shepstone ( b. 1852 ) served in various native expeditions, as assistant-commissioner in Zululand, in the South African War, 1899-1902, and became in 1909 secretary for native affairs ( Natal ) and secretary of the Natal native trust.

In RAF jargon the letters " HC " ( from High Capacity ) referred to nuclear bombs in the megaton range.

Lash Out grew from different HC / punk bands in this scene, but was soon to enter the darker side of the musical spectrum.

Murray then signed for Swiss Nationalliga A side HC Lugano in 2007.

According to the Curtiss-Wright research, the extreme that controls the amount of unburned HC in the exhaust is the rotor surface temperature, higher temperatures producing less HC.

Most present-day vehicles that run on gasoline are fitted with a " three way " converter, so named because it converts the three main pollutants in automobile exhaust: an oxidizing reaction converts carbon monoxide ( CO ) and unburned hydrocarbons ( HC ) to CO < sub > 2 </ sub > and water vapour, and a reduction reaction converts oxides of nitrogen ( NO < sub > x </ sub >) to produce CO < sub > 2 </ sub >, nitrogen ( N < sub > 2 </ sub >), and water ( H < sub > 2 </ sub > O ).

This catalyst uses O < sub > 2 </ sub > ( oxygen ) in the exhaust gas stream to convert CO ( carbon monoxide ) to CO < sub > 2 </ sub > ( carbon dioxide ) and HC ( hydrocarbons ) to H < sub > 2 </ sub > O ( water ) and CO < sub > 2 </ sub >.

No 2. 0 GT version was offered with the new range, although the 2. 0 became the sole engine offering for Canada, where the HC became the Firenza, marketed by Pontiac / Buick dealers without the Vauxhall name.

A version of the Viva HC, called the Chevrolet Firenza, was produced in South Africa, where it offered the British 1. 3 or a Opel 1. 9 L engine.

The 929 was updated in 1986 ( 1987 in some markets ) with the HC platform and a 3. 0 Liter V6 engine.

Although Ford marked its standard 2. 0 L engine as a HC it actually uses engine codes meant for the ' increased performance variant ' engines ( coding starting with ' NE ').

Introduced in 1983 as the 1. 6L F6, this engine was found in the Mazda B-Series truck and Mazda G platform models such as Mazda 626 / Capella as well as many other models internationally including Mazda Bongo and Ford Freda clone, Mazda B-series based Ford Courier, Mazda 929 HC and the GD platform-based Ford Probe

The Falcon H variant had a Gardner engine with the Voith gearbox mounted ahead of the rear axle, the later Falcon HC had the Voith transmission mounted behind the rear axle and close-coupled to the Gardner engine.
