The Advanced Internal Combustion Engine Technologies Report

Share Article just published a new market research report: The Advanced Internal Combustion Engine Technologies Report.

This report looks at the market drivers currently affecting the advanced powertrain sector, in particular fuel economy, CO2 emissions, fuel prices and criterion emissions.

Furthermore, the report provides detailed analysis of spark-ignition, compression-ignition and combined spark and compression ignition engines technologies.

Powertrain has always been perhaps the single most critical aspects of the automotive engineering; the decision taken in the early years of the 20th century to concentrate on internal combustion engines (ICE) rather than electric traction or sterling cycle heat engines has meant that throughout the last century development of ICE was absolutely critical, not only for the competitive aspects of the automotive and commercial vehicle industries, but also in terms of much of the military and civilian aircraft sectors, marine and stationary engines.

As one well-known commentator on technology once said, “if as much research and development resource had been devoted to the sterling cycle engine as has been invested in the sterling engine, we would all be driving around in vehicles powered by external heat engines”. And, while this quote might seem to express a gross simplification of the real situation with vast variability across the realm of ICE engines with different cycles, spark and compression ignition, different levels of forced induction and many variations in control systems from the simple to the very complex, it fails completely to identify the fact that a combination of concepts is now needed to meet requirements for further efficiency.
