Outline• Introduction to the project• Possible applications• Progress• Results and predicted results• Status


Introduction


Introduction

• Constant volume chamber• Heat• High volatile components• Sudden pressure drop• Creates a highly energetic and a well atomized

spray


Introduction

• Highly controllable spray to engine running condition

• Uniform spray with small droplets• Less energy use• More resistant to coking

The advantages of µMist® fuel injector


Possible applicationsGasoline direct injection• Around 20 Bar at EOI• 20 Bar fuel pressure vs conditional with 200 Bar

Diesel direct injection• Around 200 Bar at EOI• 2500 Bar fuel pressure• Low pressure system in comparison

AdBlue


Progress
