Variable Valve Timing

Variable Valve Timing. Variable Valve Timing Design and Theory. As the rpm of the engine changes the “ideal” valve opening and closing points change Mechanical cam drive systems require that a compromise be made between low-rpm drivability and high-rpm power production

Valve Train and Timing

Valve Train and Timing. Valve Train. The valves are typically operated by a camshaft rotating at half the speed of the crankshaft . It has a series of cams along its length, each designed to open a valve during the appropriate part of an intake or exhaust stroke.

FMI: Variable Valve Timing Market size and Key Trends in terms of volume and value 2015-2025

The increasing penetration of passenger and commercial vehicle is resulting in increasing vehicular emission across the globe, which is becoming a major concern towards producing cars with fuel efficient systems. To meet the emission standards and sustainability issues the OEMs are focusing to develop new technology within the engine which can enhance the performance of engine. One of the major focus to achieve this objective is to control the valve’s timing within the engine control unit with the help of variable valve timing systems. Variable valve timing system is a vital system of engine control unit with combination of electrical and mechanical system which controls the lift and duration of valve. Variable valve timing system are of two types which are cam-phasing systems and variable valve actuation systems.

Valve

A valve is a component of the piping network. It is a mechanical device, controlling or modifying the flow and pressure within a pipeline that convey liquids and gases. A valve stops, allows, control and modifies flow of a fluid media.

Basic Significance of Variable Valve Timing Engine

The variable valve timing engine is the most useful technology in modern cars which is used to boost the efficiency and overall performance of the engine. It is basically used for managing the opening and closing of the air intake valve as well as the exhaust valve. It is generally responsible allow the outside air to flow inside by replacing the exhaust emission. As it is comprised of different components such as the hydraulic components and the mechanical components. Here in the given slide, you will know about all the things related to the variable valve timing engine in a car.
