Automatic Maintainence Reminder for diesel Engines

Project code:- E14 Project Cost:- INR:- Rs. 10000/- USD:-250$

Many places in the world , equipment maintenance is normally carried out onBreackdown of the equipment. Not before No breakdown preventive maintenance are carried out

in time.Even maintenance is done by choice or optinonal And others are by calculation that aredone manually and not in technical way And some are reminded by professional and sometimes

not done at all because it has escaped one or two people.

This project will prove to be a n useful piece of equipment in order to carry out breakdown

preventive maintenance.



Periodic preventive maintenance canot be done without keeping a watch on to the running hoursof the engine . this can only be achieved by using a realtime clock into the circuit, which can

keep the account of engine running .

We have used the on board timer0 by programming to acheve the clock function. This clock ony

runs when engine is running other wise it dose not advance. An engine starting information mustbe fed to microcontroller in order to start the clock . Most of the engines have techo generator connected,output of the techo-generator should be used in such a way that it energises the relay

and the, active close contacts can be used to signal the microcontroller to start the clock function.When engine stops, techo generator output will become zero,

Relay circuit will de-energise and normally close contact will open and micontroller clock function will halt.

Two line by 16 character lcd has been used for indication purpose. When the engine is at halt, lcd

will show previously engine driven period in hours and in minutes.When engine is running,

clock running (red)led will blink (one sec off, one sec on) that indicate that internal clock hasstarted, also the lcd will be updated by the program , you can see the minutes and hours being

advanced.

Most of the engines are connected with the various safety devices . Fuel ,lubrication oil, coolingwater and air, these must be filtered before fed to engine. they should be fed at a proper pressure

as described in the engine operating manual.With the prolong use ,these filter need to be cleaned, as the filter get clogged the pressure willstart falling. Safety device connected with the particular filter and pressure switch will raise an

alarm whenever any of these parameters rises abive or below the noral operating range. All of these sensors has a relay circuit to sound an alarm bell or to give a signal to the external devices.



In our project we have four of thse input points . Input from the various sensors will come tothese points These are oil sensor ,fuel sensor, air sensor and viscocity sensor. As I have

explained before when ever any sensor get actuated,

it enerzises a relay which makes the contacts which are connected to external alarm circuit With

this project, in the class room, you can just short these input terminal points with the piece of wire in order to actuate the alarm circuit.Oil viccocity is the property of the oil it changes with the temperature and use . it should also be

within the range as specified in the operating manual of the engine. It matter most in thehydraulic equipments ,increase in viscocity lowers the performance of the engine.

Indication panel has five leds to indicate the various alarming conditions along with the sound

buzzer.Power supply section supplies regulated 5v dc to micro-controller and other circuit and 12v

supply for the shut down relay.
