Smart Internal Combusion Engine Exaust Monitoring & Control System

Abstract

Control over urban air pollution turns out to be an enormous challenge due to not only the rising numbers of total vehicles but also the increased toxic risk of diesel cars.Every vehicle will have emission but the air pollution occurs when it crosses the standardized values. The main reason for this breach of emission level being the incomplete combustion of fuel supplied to engine, which is due to the improper protection of vehicles. This emission from vehicles can be controlled but cannot be completely avoided. The pollution level can be minimized by the use of innovative and technical methods. This paper aims at using semi-conductor gas sensor at the exaust of vehicles which detects the level of pollutants. When the emission level goes beyond the already set threshold level,by using GSM,a messege will be send on the drivers mobile number also there will be a buzzer in the vehicle to indicate that the limit has been crossed and the vehicle will stop after a certain period of time a cushion time given to the driver for parking vehicle. During this time period, the GPS starts locating the nearest service stations. After the counter of timer runs out, the fuel supplied to the engine of vehicle will be cut-off by using fuel injector circuit and the vehicle has to be towed to the mechanic or to the nearest service station. A microcontroller moniters and controls the syncronization and execution of the entire process.. This project, will benefit the society and help in reducing the air pollution. when implemented as a real time project.
