Mazda Announces New Compression Ignition Engine (https://www.reuters.com/article/us-mazda-strategy-idUSKBN1AO0E7)
...
A homogeneous charge compression ignition (HCCI) engine ignites petrol through compression, eliminating spark plugs. Its fuel economy potentially matches that of a diesel engine without high emissions of nitrogen oxides or sooty particulates.
Mazda's engine employs spark plugs under certain conditions, such as at low temperatures, to overcome technical hurdles that have hampered commercialization of the technology.
...
Compression Ignition Boosts Efficiency Up To 30% (https://www.theverge.com/2017/8/8/16099536/mazda-compression-ignition-engine-technology)... a gasoline engine that doesn’t always need spark plugs to ignite the fuel and air mixture and promises greater efficiency along the lines of a diesel engine. Instead, it finds the most efficient way to operate depending on driver demands, various settings in the car, and external conditions. Spark Controlled Compression Ignition, as Mazda calls its proprietary system, works because it behaves more like a traditional gasoline engine despite the diesel-like technology and having a supercharger to boost power, the company said.
...
The setup is basically what’s known as homogenous charge compression ignition, and it’s based off of lots of existing technology that other companies have long looked into. Ford and General Motors are just two companies that have been experimenting with it in the last decade or so, but haven’t been able to put it into production yet.
Mazda released few other details about the engine other than it would be released in 2019 ...
