Assessing the Climate Trade-Offs of Gasoline Direct Injection Engines

Characterisation of Particulate Matter Emitted from Aviation Gas Turbines and Spray-Guided Direct Injection Gasoline Engines

Knock Suppression Calculations In Highly Turbocharged Gasoline/Ethanol Engines Using Direct Ethanol Injection

Calculations are described of knock suppression using direct ethanol injection in spark ignition gasoline/ethanol engines. The calculations show that evaporative cooling from direct ethanol injection, coupled with the high octane rating of ethanol, can be highly effective in inhibiting knock, thereby allowing use of small turbocharged engines with substantially increased efficiency. The calcula...

Hybrid Command Governors for Idle Speed Control in Gasoline Direct Injection Engines

Combustion Modeling for Modern Direct Injection Diesel Engines

In order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. In this field, computational tools like CFD and engine cycle simulation play a fundamental role. Therefore, the goal of the present work is to simulate a high speed DI diesel engine and study the combustion and major diesel engine emissions with more deta...

Considering Trade-offs When Assessing Resilience

This article describes the development of a prototype Resilience Analysis Grid for rail traffic management. The findings from testing of the initial model led to the identification of a set of potential vectors for improvement, in particular the need to integrate trade-offs. Based on Resilience Engineering trade-off theory this paper discusses how to integrate trade-offs into the system descrip...
