ENGINE MANAGEMENT SYSTEM

Introduction This study evaluates the operating principles of vehicle fuel systems, vehicle ignition systems and pressure charging of engines. The report attempts to evaluate the operating features of actuators and sensors used in the ignition systems and engine management system of vehicles. It also analyzes the types of pressure charging systems, its shortfalls and how it affects the enhanced power of the engine. The secondary sources which form the bulk of this report are primarily research from various sources. The paragraphs below look into the sensors and actuators and the pressure charging systems.

Introduction

Fire in Goafs (mines) is considered to be a potential environmental and health risk throughout the globe. Although, plenty of conventional fire extinguishing methods has been proposed in the past, yet they contain side effects. The authors in propose a novel fire management system using expansion form for fighting with fire at the top of goafs. The system contains a jet device for adding foaming agent produced by foam generator. The foam is powered by water pressure and compressed gas that are intrinsically safe for operating in mines. The expansion foam propels itself upwards to extinguish fire at the ...

The insurance agent was correct that the seafood was contaminated with the fumes that resulted from the fire. Toxic fumes quickly diffuse through the air. The toxic fumes were absorbed by the polyethylene curtain which covered the food despite it being thick (Brook et al. 2660). Therefore, the seafood needed to be thrown away since it had the toxic fumes.
