    Abstract: A modularized multifunctional variable valve actuation system for use in a six-cylinder internal combustion engine. The system mainly comprises fuel supply modules (5 and 6), a phase limiting module (2), a mode selection module (22), control modules (3 and 4), a fuel transfer module (7), and a valve actuation module (1). The phase limiting module (2), with an extremely simple structure, implements a valve closing process not limited by operational phases of the fuel supply modules (5 and 6), and at the same time, requires only two fuel supply modules (5 and 6) and two two-way two-position valves (141, 142, and 143) to implement a continuously variable valve event, and requires only two fuel supply modules (5 and 6), two three-way two-position valves (191, 192, and 193), and one two-way two-position valve (141, 142, and 143) to implement a fully variable valve event, thus greatly reducing costs. The mode selection module (22) implements flexible conversion of an actuation mode and a braking mode of an internal combustion engine. Components of the system are functionally independent, modules are selected on the basis of requirements such as a gas distribution mode, the flexibility of valve operations, and the presence or absence of the braking mode, and the need for altering other modules is obviated. Thus, the system has a great suitability and a wide range of applications.
