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.
When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically driven radiator cooling fan, generally located at the front of the water pump and driven by a belt and pulley connected to the engine's crankshaft. This saves power, since the engine does not have to fully drive the fan.
The CG engine is a 1.0 L, 1.3 L or 1.35 L straight-4 piston engine from Nissan's Aichi Kikai division. It is an aluminum DOHC 16-valve design. The engine was developed for use in the Nissan Micra/March K11 series. All engines featured multi-point fuel injection. Redline is at 7300 rpm.
Electric fans are controlled by a thermostatic switch or the engine control unit. Electric fans also have the advantage of giving good airflow and cooling at low engine revs or when stationary, such as in slow-moving traffic. Before the development of viscous-drive and electric fans, engines were fitted with simple fixed fans that drew air ...
Cooling system regulation includes adjustable baffles in the air flow (sometimes called 'shutters' and commonly run by a pneumatic 'shutterstat'); a fan which operates either independently of the engine, such as an electric fan, or which has an adjustable clutch; and a thermostatic valve or a thermostat that can block the coolant flow when too ...
In 1987, Nissan began work on an engine exclusively for race use; the result was the VEJ30 engine, developed by Yoshikazu Ishikawa. This engine was based on old technology, and was not a success. For 1988, the VEJ30 was improved by Yoshimasa Hayashi and renamed the VRH30. Changes included increasing the displacement to 3.4 L (3,396 cc).
You may not think of your skin as an organ, but it is — and it can be affected by inflammation just like any other organ. Discoloration (especially redness), itchiness, plaques, flakes, bumps ...
