Summary:

This paper presents a new firing concept for internal combustion engines called APIR and its performances.This concept attempts to merge the best of both Compression Ignition (CI) and Spark Ignition (SI) engine worlds. The application of this concept to a standard SI engine, leads to a consequent improvement of the firing and combustion performances. Initiation and combustion develop with a speed and a repeatability incomparable with the spark plug firing case. The use of the APIR device leads to an increase of the engine operating range in terms of lean operating limit and thus lean burn torque range.This paper points out that the APIR device has a lower knock sensitivity and isn't much affected by the in-cylinder aerodynamics. Thus, it can be shown that to take full advantage of the APIR concept in terms of efficiency and pollutants emissions, the SI engine must be redesigned in terms of compression ratio and in-cylinder aerodynamics
