Hence, keeping a check on oil levels is essential to keep all the parts in the best condition and get better performance. Oil lubrication is essential in the variable valve timing system. The elements that come into action to obtain a variable synchronisation include:

This process enhances the volumetric efficiency. Engines increase the intake valve timing to fill the cylinders and the variable exhaust valve timing to improve the engine performance. VVT engines are designed to overcome this deficiency of power. This reduces the amount of air-fuel mixture in the cylinders which result in power loss. Moreover, these older engines at higher rev or speed reduce the intake and exhaust valve timing. Older conventional models used fixed engine speeds for valve opening and closing. For instance, Honda uses VTEC technology, Toyota has VVT-i engines and Renault and Volvo use CVVT.Ī vehicle has intake and exhaust valves that work according to engine speed. Different auto manufacturers use various acronyms for their VVT technology. In their engine, you can find different makes and models equipped with variable valve timing solenoids. Let’s go through the variable valve timing’s working and symptoms of bad VVT solenoid: VARIABLE VALVE TIMING Nissan’s 370z variable valve timing engine, also known as variable valve event and lift (VVEL) Variable valve timing (VVT) is one such innovation that has improved the overall performance of the vehicles. Eco-friendly engines, powerful road performance and efficiency of vehicles have attracted masses towards automobiles. Research and development in the automotive sector has allowed many advancements.
