The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
EGT Sensor on "Ambulance Package" Chassis Cab Trucks. Certain 2011 and 2012 F-350 through F-550 trucks with the "Ambulance Package" had faulty EGT sensors. Failures could cause vehicle shutdown while driving or difficulty restarting. Ford issued a recall (recall 13S10) to replace the sensors, primarily in emergency vehicles.
This renders the camshaft position detector and knock sensor redundant. This function also enables the effective detection of misfires, which is an OBD II demand. The fuel injection is fully sequential and is dependent on the MAP (Manifold Absolute Pressure).
EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
To deal with this problem, in 2005 Volkswagen licensed Mercedes' urea-based selective catalytic reduction (SCR) system called BlueTec for future diesel engine development. [ 56 ] [ 53 ] While effective at reducing NO x , an SCR system like Bluetec was expensive, high-maintenance and required more space than other methods, making it unsuitable ...
A control loop is permanently monitoring the signal of one or more knock sensors (commonly piezoelectric sensor which are able to translate vibrations into an electric signal). If the characteristic pressure peak of a knocking combustion is detected the ignition timing is retarded by steps of a few degrees.
It's commonly known as "Detonation or Knock". Engine management systems can overcome pre ignition by the means of a knock or detonation sensor. The sensor will detect pre ignition and retard the engines timing to protect the engine from damage. Undesired engine behavior will occur such as loss of performance or power.
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
