Automatic Rain Operated Wiper

June 25th, 2010 by admin | 106 Comments | Filed in Automation, Automobiles, Mechanical Engineering Projects

This Mechanical engineering project requires the help of electronic components for working. The design of automated rain operated wiper is based on an electronically controlled motor whose controls are actuated by the presence of water droplets.

The required components for this project are:
1. A conduction sensor circuit
2. Control unit
3. A wiper motor
4. A glass frame

 

AUTOMATIC RAIN OPERATED WIPER
SYNOPSIS
The aim is to design and develop a control system based an electronically controlled automotive rain operated motor is called AUTOMATIC RAIN OPERATED WIPER.

Rain operated motor is consists of conduction sensor (Tough sensor) circuit, Control Unit, wiper motor and glass frame. The sensor is used to detect the rain or water flow. There is any rain on the class, the sensor senses the rain … Read the rest

Integration of Automatic Transmission for AutoRickshaw

June 25th, 2010 by admin | 20 Comments | Filed in Automobiles, Mechanical Engineering Projects

Auto-rickshaws have manual transmissions with 4 forward gears and 1 reverse. This mechanical engineering project is about integrating an automatic transmission to an autorickshaw replacing manual transmission gear box.

Manual transmissions are operated with the help of a clutch box, a gear knob and meshing of different sets of gear boxes. But an automatic transmission works with the help of planetary gears.

The working of automatic transmission for the project is the same as that in a gearless scooter. But here while integrating this transmission with an auto-rickshaw the size of the transmission equipment is different from that of scooter. So you will need to machine transmission elements.

Fabrication of Motorized Screw Jack for vehicles.

June 20th, 2010 by admin | 137 Comments | Filed in Automobiles, Mechanical Engineering Projects

Motorized/Automatic Screw Jack for vehicles

Fabrication of a motorized screw jack is easy especially when the parts are avaialble in the market. This mechanical engineering project can be easily completed by integrating an electric motor with a screw jack.

A screw jack or a Jackscrew is operated by turning a lead screw. The height of the jack is adjusted by turning the lead screw. This can be done either manually or by integrating an electric motor with it. This integration is our project.

The difficult part in the project may be finding a low speed motor that is able to work at 12V. This is because the battery output of an automobile is 12V, and the electricity needed for the operation of the screw jack is taken from this battery. … Read the rest

Solar Car Design-How to Build a Solar Car

The title of the project may be misleading, because it not going to be easy building a full sized solar car. It is not only difficult but also very costly. So it is better to do this as a project which includes lots of study and then a demonstration of how the solar energy can be converted and stored in batteries and then how it can be used to run the vehicle. May be with the staffs permission you may be able to use your college’s water heater solar panel if there is any. The design part of the project includes lots of calculations on how much energy can be stored, how fast the energy can be stored, how maximum efficiency … Read the rest

Fabrication of Electromagnetic braking System For Automobile

June 18th, 2010 by admin | 38 Comments | Filed in Automobiles, Mechanical Engineering Projects

Electromagnetic braking System

This is one of the simplest mechanical engineering projects. An Electromagnetic Braking system uses Magnetic force to engage the brake, but the torque required for braking is transmitted manually.

The main parts of an electromagnetic brake are:
1. The coil
2. The armature.
3. The hub.

The hub is attached to the axle of the vehicle. The armature is mounted on the hub and rotates along with it. The coil is mounted on a stationary element attached to the machine frame of the vehicle. Two friction plates are mounted each on the face of the armature and the machine element holding the coil.

Working:
Electricity is applied to the coil at the time of braking. This develops a magnetic field around it and the rotating armature gets … Read the rest

Electronic Valve Actuation in Combustion Engine

June 14th, 2010 by admin | 10 Comments | Filed in Automobiles, Mechanical Engineering Projects

The aim of this project is to actuate the valves of an internal combustion engine electronically instead of mechanical methods. The advantage of having electronically actuated valves instead of the mechanical ones is that it helps to improve the engine performance by reduced fuel consumption and improved power output.

The electronic valve actuation helps to vary the valve timings infinitely in internal combustion engines which provide desired open and close intervals of intake and exhaust valves at variable engine speeds. Once the valve timings are perfected, it leads to reduced fuel consumption and greater engine efficiency.

The project covers the modeling and software for implementing an electronically actuated valve with the development of a hardware model which can be developed for future practical applications. But the project does not involve … Read the rest
