IGNITION HOOD [3 records]

Record 1 2013-09-10

English

Subject field(s)
  • Electrical Equipment (Motor Vehicles)
CONT

The sensors and actuators, along with the diagnostic computer software in the on-board computer, make up what is called "the OBD system".

CONT

By the early 1980s, numerous vehicles were using electronics and on-board computers to control many of the engine's control systems, such as fuel and ignition. Vehicle manufacturers had to develop ways to diagnose problems generated by the new electronic hardware found under the hood. Thus, the first OBD systems were developed by auto manufacturers in the early 1980s as electronic systems replaced mechanical systems.

OBS

[One of the main purposes] of the OBD system is to assure proper emission control system operation for the vehicle’s lifetime by monitoring emission-related components and systems for deterioration and malfunction.

  • Ovens, Furnaces and Boilers (Heating)
  • Gas and Oil Heating
OBS

Another development in furnace and boiler technology offers efficiency improvements of 15 to 25 per cent over the conventional furnace. This furnace is equipped with electric ignition and a built-in induced draft fan(a device that provides and ensures the escape of combustion by-products) and no draft hood. Elimination of the draft hood dramatically reduces the furnace's overall air requirement while the furnace is operating, and reduces the warm air outflow up the chimney on the off-cycle.

English

Subject field(s)
  • Mineral Processing (Metallurgy)
  • Equipment and Plant (Metallurgy)
CONT

Essentially, all sintering is performed on traveling grates of the Dwight-Lloyd type. Ignition is provided by burner hoods located over the grate, and combustion is completed as the material nears the end of the grate.

French

Domaine(s)
  • Minéralurgie (Métallurgie)
  • Équipement et matériels (Métallurgie)
CONT

Dwight-Lloyd ou chaîne d'agglomération. C'est l'outil de la Fonderie le plus compliqué mécaniquement. Le Dwight-Lloyd a pour mission de griller la charge et de l'agglomérer. Il est composé des éléments suivants: 1 trémie pour la couche d'allumage; 1 trémie pour la couche d'allumage; 1 trémie pour la couche principale; 1 hotte d'allumage revêtue de réfractaire; 1 station d'entraînement avec 2 roues de remontée.

OBS

L'allumage se fait à l'aide de brûleurs; ensuite, la combustion du coke se poursuit par aspiration d'air à travers la couche. (...) Des brûleurs sont alors disposés dans une hotte au-dessus de la chaîne [de sintérisation].
