Effectiveness of braking system are essentials part to avoid accidents and save life. Also majority of accidents in vehicles are happen due to chassis failure and braking failure. Here I take the subject to understand the causes of failure of hydraulic brake systems in SUV. The brakes are the most important active safety of a car and one of its key pieces. However, many drivers do not seem to understand it well. According to a statistics, about 40% of the defects detected by the ITV correspond to the brakes. It is not enough to bring the car to the shop when something goes wrong. Leakage is major problem in TMC. In any case if tmc leak it may leads to accident. So leakage and performance of tmc is most important. Various parts of tmc such as piston, spring does not leak. The body of tmc may leak as well seals used in assembly of piston. In this project the different reasons of leakages are finding and simulation with CFD are carried out.

Over 99.5% of the exhaust gases are a combination of nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon dioxide, which contributes about 5% of the total volume, the diesel engine exhaust consists of elements which are part of the natural atmosphere and are not harmful to the environment. Carbon dioxide emissions are directly related to the efficiency of the combustion unit. The higher efficiency obtained with lower amount of CO2 emissions. In this study we are interested in the effects of exhaust gas recirculation (EGR) on combustion and emissions direct injection diesel engine. In particular, the effects of carbon dioxide (CO2), water (H2O), carbon monoxide (CO), some different quantities of EGR, analysed and quantified numerically. Other parameters tha affect the rate of oxides of carbon in the bowl shape, the Mexican hat and spherical geometry are analyzed in this work. Therefore, A modified version of the computational fluid dynamics (CFD) Code KIVA-3V has been used for modelling combustion process and engine emission, in particular carbon oxides emission and its control. Simulation was carried out by using a two-stroke single-cylinder direct injection diesel engine.
