Spark Plug Fuel Direct Injection Natural Gas Engine

Natural gas has been extensively used in automotive engines due to its abundance availability, adaptability to existing engine design, cleaner emission and competitive price. However, converting engine to natural gas always results in power drop. One of the most practical solutions is direct fuel injection. Research on natural gas direct injection engines proved that engine power similar to gasoline is achievable but with the penalty of engine retrofitting costs (cooling water jacket and piston crown modification). Spark Plug Fuel Direct Injection (SPFI) offers a cost competitive and a technically simpler option for conversion to natural gas direct injection. This book explore the development of SPFI and initial engine test which was carried out in a single cylinder engine. Encouraging results were obtained and more work are being carried out for its design and operational optimization. Stay tuned for its technological progress.
