Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
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.
Although the engine VQ37VHR gains only 2 lb⋅ft (3 N⋅m) and 8 lb⋅ft (11 N⋅m) in the Nissan 370Z Nismo, torque over the VQ35HR and this higher torque arrives at 5,200 rpm vs 4,800 rpm in the VQ35HR, the torque curve itself is improved and flattened via VVEL variable valve timing for better throttle response and low rpm torque.
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).
Nissan VQ engine, Nissan RB engine The VR is a series of twin-turbo DOHC V6 automobile engines from Nissan with displacements of 3.0, 3.5, and 3.8 L. An evolution of the widely successful VQ series , it also draws on developments from the VRH , JGTC , and Nissan R390 GT1 Le Mans racing engines.
Originally developed to be used in the Nissan P35 race car for Group C racing, the VRT35 would later see use in the 1992 All Japan Sports Prototype Championship.Required to be 3.5 litres by Group C rules, the engine had to not only be high-revving like a Formula One engine, but also have endurance capabilities.

Where an additional cooling fan is driven by the engine, this also tracks engine speed similarly. Engine-driven fans are often regulated by a fan clutch from the drivebelt, which slips and reduces the fan speed at low temperatures. This improves fuel efficiency by not wasting power on driving the fan unnecessarily. On modern vehicles, further ...
