Cylinder deactivation is a potential method in improving efficiency and fuel consumption in SI engines. The optimal strategies about driving torque at different operating conditions can improve the fuel consumption in engine. Many recent researches have demonstrated that the cylinder deactivation modes can be successfully applied in improving engine efficiency at different engine loads. Different cylinder deactivation strategies have been applied for full range of engine load. However, deactivating cylinder in engine requires complex structure of valve train system. The study proposes a design valve train, which is improved from the conventional valve train system in an inline SI engine with 4 cylinders, to control for deactivating cylinder. The study results show that the proposed design, which differs to the existing valve train design, can deactivate one or two cylinders modes that depend on part load or medium load in vehicle. In addition, the novel design with simple structure and easy control can fully satisfy the controlling of cylinder deactivation strategies in SI engines.
