Abstract

The internal combustion engine is the powerhouse of motor vehicles. The basic fuel used for self-ignition engine powering is diesel oil. The efficiency of an internal combustion engine depends on many factors and is defined by such parameters as power output, torque, and the engine rotational speed. The engine performance parameters can be improved by modification of the manufacturer’s computer software that controls the engine operation. The study presents results of tests of a drive unit involving adjusting the fuel injection controller settings. The modifications involved increasing the fuel dose and the air charge pressure. Tests were carried out on a load bearing chassis dynamometer. The research object was a self-ignition engine with 109 KM power and Common Rail injection system. Power and torque measurements were carried out for the engine rotational speed range up to 4000 rev/min. It was found that modifications of the manufacturer’s engine computer software contribute to power and torque increase for all the rotational speeds.

Highlights

The first self-ignition engine was constructed by Rudolf Diesel in 1893
This study aims at checking the impact of the engine computer software modifications on the torque increase depending on the drive unit rotational speed
Modifications of the fuel injection controller standard settings contribute to the engine power and torque increase which has been proven in many research centers

Summary

Introduction

The first self-ignition engine was constructed by Rudolf Diesel in 1893. Not sooner than after development of petroleum refining technology diesel oil was found to be a much more universal fuel when used in self-ignition engines [1,2]. The twentieth century was a breakthrough in petroleum extraction and refining which made it the fastest developing branch of industry [3,4]. Advantages of fuels designed for these engines are their good lubricating properties, lower viscosity and high octane number which indicates the engine ability to self-ignite. According to PN-EN590+A1:2017-6 norm [6] diesel fuel should have specific parameters which are presented in table 1
