Research and development of different systems will be investigated in this paper. An overview on the chassis, engine, transmission, suspension, lighting, safety and assistance systems …show more content…

Air ducting and charge-air cooling The engine has two intake muffler modules, the wedge shaped gap is used to distribute the air for both filter housings with zero losses in the air in the pipes, the charge-air cooler has a counter flow design, with a separate low-temperature coolant circuit and its own expansion tank. This layout, which is the same in all S-class vehicles, achieves a very good response behavior and charge-air cooling values, in limited installation space. Fig. 3. Exhaust port design: Section through cylinder head and turbocharger D. Fuel Injection System The New generation of the spray-guided Gasoline Direct Injection system, uses BlueDirect combustion process and identical piezo injectors, in the S-class model Engines. The main idea of the gasoline direct injectors is that the fuel will be injected and burnt directly inside the combustion chamber. This is optimized by a control module that calculates the precise amount of fuel needed to reach the desired engine conditions depending on the Speed, Turbochargers and the Throttle …show more content…

TRANSMISSION The transmission system in the S-class is an automatic transmission system known as the 7G-tronic plus. which has seven speeds transmission gears, and contains electrical components and a control module to optimize and regulate the transmission, this technology is the modified version of the previous 7G-tronic transmission system • The development in lockup clutch provides the cooling oil a direct flow towards the coupling package and thus providing an effective and efficient cooling. The increase in the gap between the clutch disks is so that the clearance of the coupling package is optimally used and the drag torque is significantly reduced. This results in much improved performance, especially under cold-starting conditions, when typically engaging a gear reduces the rotating speed of the engine. A. Centrifugal pendulum
