Scania Trucks: Decreasing Emissions and Increasing Efficiency

Decent Essays
INTRODUCTION

A phrase that we often hear from customers who send their trucks for repair is, “This is a diesel engine; the problem should be easy to diagnose.” The right part about that statement is that the customer ¬realizes that he has a diesel engine. Simple operation, high reliability, high thermal efficiency and low fuel consumption are few key reasons for success of Diesel engines and its varied application from land based automotive and power generation to marine propulsion applications in deep sea. Engine’s continuous availability is a crucial aspect especially in transportation sector where movement of trucks and ships depends solely on the operation without any breakdown.

This project is limited and focused on diagnosis of fuel injection system of diesel engines of Scania Trucks and buses only. The approach is to first investigate methods of fault isolation and detection of faulty component with corresponding fault mode on similar systems. Later the most optimum method to deal with statistical and experimental data set will be used to create a diagnostic model. The data is collected from service reports over the past years and various experiments done on major components of fuel injection system. With this diagnostic model, the prediction of faulty component will become easier, less time consuming and economical, thus increasing the operational time of trucks with reduced downtime.
