Abstract. A new concept of reduced quasi-dimensional combustion model for a direct injection diesel engine is developed based on the previously developed quasi-dimensional multi-zone model to improve the computational by: 5. The paper presents a method for calculating the three-dimensional flow-fields in reciprocating internal combustion engines, as a function of space and Cited by: In this paper, the three-dimensional models of three kinds of new intake manifold for engine were established. The model was divided with tetrahedral mesh using software GAMBIT. Three-dimensional flow simulation was conducted using software FLUENT and the velocity contours of intake Cited by: 2.
combustion engines have an important effect on engine performances, emissions of pollutants and noise. To control the engine output torque by the intake airflow restriction, a throttle valve must be installed between the air cleaner and the intake manifold. Due to the complex nature of this unit geometry and the resulting flow field, a 3D flow File Size: KB. The ultimate aim of this study is the development of an engine modeling approach that would facilitate the design of model-based control techniques for diesel engines. This will allow for the development of more generalized, modular control strategies for different engine types and sizes as opposed to the commonly practiced map-based engine control strategies that depend on maps and Cited by: 2. High swirl-inducing piston bowls in small diesel engines for emission reduction. Detailed in-cylinder three-dimensional modeling of air motion and combustion is used to explain the trends, and is further used to arrive at an optimal bowl geometry. 2. by:
