Train System

One of the important methods for studying the valve train system is simulation. So the feasibility of valve motion simulation by Pro/E is discussed in this paper. After model establishing and connection completing, the valve motion is simulated and some results are reached. It can be seen from the results that valve motion can be simulated based on Pro/E environment. It also be seen that the valve acceleration varied at high frequency and the impact between the valve and seat is existed for the studied valve system. For studied valve it meets the demand of the engine

Train System

The increasingly strict emission regulations in combustion engines are raising high requirements for the engine valve train system. In this paper, a novel multifunctional wear apparatus is designed to study the performance of engine valve train components. The apparatus employs a mechanical loading system, which consists of a special eccentric wheel and disc springs that apply the combustion loads, and the contact configurations and loading conditions of valve train components are simulated. It has three test functions for different components through specifically designed fixtures. The first function aims to evaluate the interaction between the valve seating face and the seat insert at high temperatures and loads. The second function is used to study the friction and wear properties of the valve stem and the valve guide. The third function is designed to evaluate the performance of the valve seals. At last, a verification test was carried out by the proposed experimental method. A pair of new exhaust valve and seat insert is tested for the performance evaluation of the first function. The wear mechanisms acting on the pairs interface are shown to be a combination of oxidative wear, adhesive wear, as well as fatigue flaking.
