In order to reduce the weight for improving fuel efficiency and enhance the performance of automobile engines, research into plastic manifolds compared to conventional aluminium and iron manifolds is becoming a trend for the intake structure design. In this paper, finite element simulation is employed to design and optimize a plastic manifold for a four cylinder intake structure. The yield strength of intake manifold structure for an applied burst pressure of 6.5bar is verified using finite element analysis. Based on the simulation results and identification of strength critical zones, stiffeners were introduced to improve the plastic intake manifold design for an operational temperature range of 20-120 degrees Celsius.Keywords

Three different configurations of plastic oil-gas separator for diesel engine valve chamber cover were studied using numerical simulations. The distribution of flow velocity, pressure and oil droplets collection from simulation results were assessed to find out an optimum design for the oil-gas separator. Further, the oil-gas separation efficiency from simulation and experimental test was also reviewed to verify the simulation model as well as selection of the best design amongst the considered three configurations of the oil-gas separator.Keywords

Computational fluid dynamics analysis for three intake manifold schemes were carried out by STAR-CCM software to obtain the velocity field, pressure field and pressure loss equilibrium. Based on the simulation results, the best scheme was chosen to verify and validate the numerical results through a runner test. The simulation and test results helped the designer to accurately find the unreasonable section of intake manifold with a view to re-design or apply minor modifications followed by re-analysis of the intake manifold which can reduce the number of experiemental tests.Keywords

The working process of oil and gas separator is a very complex gas-liquid two-phase separation movement; it is difficult to obtain internal flow condition using analytical method. In this paper, with DPM, SIMPLE algorithm and random walk model, velocity distribution, pressure distribution, oil droplets motion trajectory and separation efficiency were analyzed by numerical simulation method. This analysis is helpful to understand flow law of gas-liquid two-phase fluid in oil and gas separator, and then optimize separator structure, short its development cycle, which has important application value in engineering.Keywords
