Engine Diagnosis for Detecting Errors

Abstract

Fuel consumption and emissions of vehicles are two main critical aspects considered in the transportation
industry. It’s because of lack of more efficient vehicles, better fault diagnosis and an advanced Driver Information
System (DIS). It is necessary to announce fuel consumption of the vehicle in present driving condition to driver. By this
drivers can aware of consumption level of fuel at their present driving condition. However, most motor companies are
unwilling to reveal the vehicle information. Therefore, easily obtained diagnostic information can be used to estimate the
fuel consumption roughly. Road accidents are also happening with poor knowledge in vehicle fault diagnosis. Casualties
are mainly caused by automobile component malfunctions and human negligence. It is thus important to ensure the
healthy status of each component of the vehicle. However, the inspection of an engine’s health status of and the
corresponding internal combustion processes are usually time consuming and expensive because they must require
experienced mechanics and expensive equipment. Experienced mechanics available only at cities for scanning and
diagnosing errors. So it’s very difficult and quite expensive to take the vehicles to cities even for simple errors. In the
majority of cases even the parts are repaired, the problem may not be resolved, because poor understanding of error
codes. However the mechanics recommend only that automobile owners purchase and replace components even at
unnecessary conditions to resolve errors. Consequently, numerous components are thrown away and wasted. Hence, a
low-cost, real-time fault diagnostic for running automobiles is in need. Our objective is to educate and train the village
residency drivers and owners about scanning and diagnosing vehicles. This paper provides effective and better
diagnosis to detect errors by using OBD-II (On Board Diagnosis-2nd generation) protocol.
