ABSTRACT:
The invention relates to a spark-ignition engine with a highly structural compression ratio greater than 15:1, throttle regulation, externally supplied ignition and with direct fuel injection into a precombustion chamber, which is connected to the main combustion chamber via an overflow channel. The fuel is injected into the precombustion chamber during the compression stroke and is ignited by a spark plug located in a manner that is as central as possible.
