The analysis of the mechanismsused, the principles of variable valve timing actuator and layout solutions. The same research was carried out, aimed at the study of the principles of variable valve timing, evaluation of the advantages and disadvantages of the different systems and mechanisms that control range, variable valve inlet and two camshafts. Based on the analysis of existing systems created the concept of variable valve timing and built a prototype engine.The design of variable valve timing system, the design of the mechanism of valve timing change. Constructive and assembly system features variable valve timing. The principle of the control valve timing. After debugging control systems were tested engine with variable valve timing system. The use of variable valve timing system showed a reduction in fuel consumption of up to 15% increase in torque at medium speed to 18% increase in maximum power of up to 19% compared with the base engine with constant valve timing.
