Research on Virtual Prototype Technic of Valve Train System in Internal Combustion Engines;

By using both AVL-Tycon (Valve trains system dynamics analyzing software) and AVL-Boost (Engine cycle simulation software), valve train system of an electronic-controlled vehicle diesel engine is analyzed and improved.

In this calculation model for the movement rule of valve train system with rocker, the position of every compo- nent is determined, so it has a high precision.

Dynamic Analysis of Overhead Valve-train Based on Multi-body Coupled System;

The widely used valve-train simulation software,AVL-TYCON,was applied to perform both kinematic and dynamic simulations for the valve-train of a four-cylinder gasoline engine.

A dynamics model for valve gear of overhead camshaft engine is presented in this paper.

The paper introduces two methods to calculate the contact stress between cam and teppet,regarding the valve gear as rigidity or elasticity.

This paper determines the motion of lower rocker arm in valve gear by the dimension of cam mechanism and derives the characteristics of equivalent cam,assuming that the rocker arm ratio varies according to the camshaft angular displacement while the push rod and both the upper and lower rocker arms are in motion.
