Abstract(E)	Laser ignition as a replacement for Spark Ignition in internal combustion engines presents potential advantages both in terms of reducing the cyclic variations between combustion cycles and reducing the overall ignition package costs, weight and energy requirements. This paper presents an analysis of the changes in Coefficient of Variation (COV) in both Indicated Mean Effective Pressure (IMEP) and the Peak Cylinder Pressure Position (PPP) due to modulation of the energy and the spot size delivered by a laser to the cylinder in an otherwise unmodified normally-aspirated 1.6 litre port-injected engine. The results are the outcome of The Laser Ignition in Internal Combustion engines (LASIIC) Project which is conducted by a consortium comprising The University of Liverpool, The Ford Motor Company, and GSI Lumonics with funding from the United Kingdom, Department for Trade and Industry (DTI), Foresight Vehicle Programme.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
