In this paper a proposed idle speed controller consisting of decoupled manifold pressure and spark retard control loops is presented. The controller incorporates a model predictive element in the selection of the bypass valve duty cycle, which is used to set the intake manifold pressure. A similar approach is easily adaptable to throttle by wire systems. A simulation model incorporating the cyc...
Untuk menghasilkan suatu kerja yang optimal dari mesin bensin, maka diharapkan pencampuran bahan bakar dengan udara terjadi sempurna sesuai kebutuhan salah satu cara optimalisasinya adalah menggunakan metode injeksi ke intake manifold. Adapun analisa proses Computational Fluid Dynamics dapat dilakukan program ANSYS FLUENT. Penelitian memodelkan model injektor persamaan matematis serta menjadika...
Data obtained from Nary calibration tests of an 18-cylinder, two-row, radial engine of 8350-cubic-inch displacement and a 14-cylinder, two-row, radial engine of 2600-cubic-inch displacement {carburetor types) were analyzed to show the correlation between the air consumption of these engines and the parameters that evaluate the air consumption from intake-manifold temperature and pressure, exhau...
Homojen dolgulu sıkıştırma ile ateşlemeli (HCCI) motorların yüksek termik verimleri ve düşük NOx emisyonları sebebiyle buji (SI) (CI) motorlara göre önemli üstünlükleri bulunmaktadır. Ancak HCCI motorlarda yanma başlangıcının kontrol edilmesi oldukça zordur. Bu çalışmada, dört silindirli SI motordan dönüştürülmüş olan bir motoru kullanılmıştır. 373 K hava giriş sıcaklığı için, emme manifold bas...
In this paper, attempting to improve the recognition rate and solve some problems such as pose, lighting variations and partial occlusion in video sequences using Orthogonal Locality Preserving Projection (OLPP). In this research, first of all face in video frames is detected for background removing. Then each set of images is distributed on a nonlinear manifold and clustered using appropriate ...
Optimizing the Filling Time and Gate of the Injection Mold on Plastic Air Intake Manifold of Engines
In this paper, Finsler metrics with relatively non-negative (resp. non-positive), isotropic and constant stretch curvature are studied. In particular, it is showed that every compact Finsler manifold with relatively non-positive (resp. non-negative) stretch curvature is a Landsberg metric. Also, it is proved that every (α,β)-metric of non-zero constant flag curvature and non-zero relatively i...
In this paper, we will study compatible triples on Lie algebroids. Using a suitable decomposition for a Lie algebroid, we construct an integrable generalized distribution on the base manifold. As a result, the symplectic form on the Lie algebroid induces a symplectic form on each integral submanifold of the distribution. The induced Poisson structure on the base manifold can be represented by m...
The object of the present paper is to introduce and study a type of non-flat semi-Riemannian manifolds, called, super generalized recurrent manifolds which generalizes both the notion of hyper generalized recurrent manifolds [A.A. Shaikh and A. Patra, On a generalized class of recurrent manifolds, Arch. Math. (Brno) 46 (2010) 71--78.] and weakly generalized recurrent manifolds ...
