A Review of Ideas for Improving Transient Response in Vehicle Diesel Engines

<div class="htmlview paragraph">Turbochargers are rightly blamed for disimproving the transient response of vehicle Diesel engines, but the serious effect of engine rotating inertia is often forgotten. Ultimately, a “no coolant” engine with lightweight ceramic parts may give substantial improvements by increasing exhaust gas temperature and at the same time reducing the inertia of engine and turbocharger components. The response of a turbocharger system can also be improved by adding energy to it, but so far such additions have required complex and costly sub-systems. A novel, cheap system is suggested.</div>
