MUI tester is basically used to check the atomization and spray pattern of the fuel injector to detect any defect if present. It is the most important part of the fuel system which is a high-pressure fuel metering pump and spray valve combined into one compact unit. This is a project of "Design of mechanical unit injector (MUI) tester machine using hydraulic system." Mechanical unit injector is a fuel injector of a loco engine used by INDIAN Railways. This vehicle speed is sensed by the proximity sensor and this signal is given to the control unit and pneumatic bumper and braking activation system. This bumper and braking activation system is only activated the vehicle speed above 30-40 km per hour. The pneumatic bumper and braking system is used to product the man and vehicle. There is any obstacle closer to the vehicle (with in 3-4 feet), the control signal is given to the bumper activation system and also pneumatic braking system simultaneously. This project consists of IR transmitter and Receiver circuit, Control Unit, Pneumatic bumper system and pneumatic braking system. The aim is to design and develop a control system based intelligent electronically controlled automotive bumper activation and automatic braking system is called AUTOMATIC PNEUMATIC BUMPER AND BREAK ACTUATION BEFORE COLLISION. The technology of pneumatics plays a major role in the field of automation and modern machine shops and space robots. By this arrangement the machining time of a work piece is reduced by half the time when compared with the conventional machines. The pneumatic source of power with control accessories is used to drive the ram or the cylinder piston to obtain the forward and return strokes. This stroke would be a rough cutting stroke for the job, compared to the forward stroke. This can be achieved by an addition of clapper box with a tool such that the arrangement on tool holder has one tool clamped on the clapper box individually. This project is uses the idle stroke as cutting stroke and hence increase the production rate. The shaping machine has an idle stroke during its return motion. A small skeleton structure has been thus devised to demonstrate the machining time reduction in shaping machines. This project intends to use shaper for high production as well. A shaping machine or simply shaper is used to machine a single job by using a single point cutting tool and hence it cannot be used for high production rates. Our project deals with the fabrication of a time reduction unit in a shaping machine using pneumatic mechanisms.
