As a result of studies made with rapeseed oil, researchers reported that rapeseed oil methyl esters can be used on diesel engines. It was determined that rapeseed oil methyl ester showed better results than soybean oil methyl ester in terms of emission. In addition, with pre-heating application, the engine torque increased at low engine speeds, CO, HC and smoke density decreased significantly. It was determined that using of rapeseed oil methyl ester shortened the ignition delay period.  3, record 1, English, - rapeseed%20oil%20methyl%20ester

L’ester méthylique de colza, qui dans un premier temps a été développé pour des raisons d’indépendance de carburant en cas de choc pétrolier, s’est peu à peu affirmé comme un carburant alternatif au gazole, notamment pour une utilisation sur les flottes captives (les bus par exemples). Après une baisse de l’utilisation due au développement de nouveaux moteurs fonctionnant avec du gazole désulfuré, l’ester a retrouvé un nouveau souffle de vie en tant qu’«additif de luxe».  2, record 1, French, - ester%20m%C3%A9thylique%20de%20colza

Interruptible igniters, are small igniters applied to gas and oil burners to ignite the fuel input to the burner under prescribed light-off conditions. The igniter shall be cut off at the end of the time trial for ignition of the main burner. Interrupted-type igniters are typically sized to a minimum of 3% of the main burner at its light off rating, typically at 25% burner capacity. The use of interrupted igniters to support ignition or to extend the burner control range should be prohibited.  2, record 3, English, - interrupted%20igniter
