INTRODUCTION

• The engine overheating is major issue to be considered

• There may be several reasons for engine to get overheated

• Major reasons for the engine overheating can be identified from the proposed system and the driver is alerted regarding that .

• The driver can take proper control action on the basis of the problem identification

PROBLEM STATEMENT

The overheating of engine is the major issue now a days. The reasons for overheating:

• Running Ac for longer duration

• Leakages in hoses

• Blockages in valves hoses

• Radiator Failure or electric valve motor failure

• Bad Thermostat

ThermostatLeakage in hose

Radiator failure

• The use of AC adds up extra burden to the Engine

• “Considering Electric AC requires bulky Motor(to provide 1 or 2 HP) to drive the compressor pump it requires remodeling of car ,so generally Car’s A/C system uses belt driven approach”

THE PROPOSED SYSTEM

• The proposed system concentrates on user safety during engine overheating

• The blockages in passages are avoided by placing tiny fan blades which are turned ON on the basis of level sensor.

• The driver is alerted to control the AC reduce the burden on over the engine

• The system can also identify whether thermostat failure

• The system also displays where the problem is.

• The development of this mechanism requires the interaction of sensors and actuators controlled by microcontroller.

THE MAJOR COMPONENTS OF PROPOSED SYSTEM:

FLOW SENSORS:

• The position of the thermostat can be sensed with the flow sensor logic

• If water doesn’t flow within the stipulated time there is failure in thermostat

• We can choose RTD( till 6000c) or Thermistor (< 2000c) logic based sensing .

• The Thermistor is low cost and fits for this application

MOTORS:

• Fans are driven by motors.• We can control this via Single channel Relay operating with 5v

TINY FAN BLADES:

Blades

MICROCONTROLLER:• Arduino/Genuino Uno is a microcontroller board based on the ATmega328P.• It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog

inputs, a 16 MHz quartz crystal.• It also contains a USB connection, a power jack, an ICSP header and a reset button.

INTERFACING THE COMPONENTS

Developed using Proteus Demo version:

THE CONTROLLER IS ARM7 LPC2138

OPERATION OF THE PROPOSED SYSTEM

Thermostat operation

SOFTWARES REQUIRED

• ARDUINO IDE 1.0.4• “Circuits.io” online simulator

RESULTS

The sensor inputs are given via serial communication and corresponding conditions are verified CONDITION 1: THERMOSTAT FAILURE (TEMP<100):Thermostat stuck in open state

CONDITION 2:THERMOSTAT FAILURE (TEMP>100):Thermostat stuck in closed state

• At intermediate levels the driver is warned about the air conditionerCONDITION 3:AC ON CONDITION:

CONDITION 4:BLOCKAGE CLEANING :

• Correspondingly the Blade motor gets turned on to clean the blockage

CONDITION 5:BLADES FAILURE:

CONDITION 6:AFTER SUCCESSFUL BLOCKAGE CLEANING:

CONDITION 7:AFTER BLCOKAGE CLEANING AND NO FURTHER FAILURE:

The radiator fans run at the required level which is already a part of the coolant system controlled by other system.

CONDITION 8:RADIATOR TO WATERPUMP FAULT AFTER BLOCKAGE CLEANING:

The radiator fans run at intermediate stage. Here after blockage cleaning there is fault in the radiator to water pump which is indicated to the user

CONDITION 9:RADIATOR TO WATER-PUMP FAULT :

CONDITION 10:NO FAILURE CONDITION:
