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.
The VG series engine was put into thousands of Nissan vehicles, debuting in Japan in the 1983 Nissan Gloria/Nissan Cedric, and in the US and other markets in the 1984 Nissan 300ZX. When the Nissan VQ engine was introduced in 1994, the VG engine was slowly phased out in Nissan cars, and after 2002 it was only available in the Nissan Frontier and ...
The Nissan Frontier is a nameplate used on two different pickup truck models by Nissan: Nissan Frontier (international) , an alternative nameplate for the NP300/Navara on some markets Nissan Frontier (North America) , a rebadged NP300/Navara from 1997 to 2021, then became a separate model since 2021
It featured the 2.0L Z20 motor that was fed by a carburetor. Its compression ratio was at a high 9.4 to 1, and produced 95 hp (71 kW) and 112 lb⋅ft (152 N⋅m) of torque. It was able to do this because it featured a knock sensor that would retard the timing by about 10 degrees to prevent the engine from knocking.
The VQ is a family of V6 automobile petrol engines developed by Nissan and produced in displacements varying from 2.0 L to 4.0 L. Designed to replace the VG series, the all-aluminium 4-valve per cylinder DOHC design debuted with Nissan's EGI/ECCS sequential multi-point fuel injection (MPFI) system. Changes from the VG engine include switching ...
A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
In 2010, Nissan updated the engine and the turbo (BV45 from GT2056V) for the D40 Navara and facelifted R51 Pathfinder to produce 140 kW (190 PS; 188 hp) and 45.9 kg⋅m (450 N⋅m; 332 lb⋅ft) of torque. [5] In 2011 the Nissan Murano was fitted with the updated engine. Applications. 2006–2014 Nissan Navara (D40)
Knock Sensor - located on engine block; retards timing if pinging/detonation is detected. Heated Throttle Body - heated by engine coolant. The QG18DE is used in the following vehicles: 2000-2006 Nissan Sentra B15 and N16; 2000-2005 Nissan Pulsar N16; 1999-2002 Nissan Primera P11.144; 2002-2007 Nissan Primera P12; 2000-2006 Nissan Almera N16
