TL;DR: In this paper, a spark-ignition engine with a highly structural compression ratio greater than 15: 1, throttle regulation, externally supplied ignition and direct fuel injection into a precombustion chamber (5), which is connected to the main combustion chamber via an overflow channel (6).
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 (5), which is connected to the main combustion chamber (15) via an overflow channel (6). The fuel is injected into the precombustion chamber (5) during the compression stroke and is ignited by a spark plug (8) located in a manner that is as central as possible.

TL;DR: In this paper, a combustion chamber of an in-cylinder direct fuel injection spark ignition engine having a pentroof composed of an intake side roof and an exhaust side roof, a piston, and a cylinder is presented.
Abstract: A combustion chamber of an in-cylinder direct fuel injection spark ignition engine having a pentroof composed of an intake side roof and an exhaust side roof, a piston, and a cylinder. The combustion chamber has a fuel injector provided between the intake side roof and the exhaust side roof inclined toward the exhaust side port, an intake port provided on the intake port side roof at an acute angle with respect to an extended line from the exhaust side roof so as to form a tumble flow of intake air along the exhaust side roof, a piston cavity with a curved surface formed on the top surface of the piston so as to reflect a fuel spray injected from the fuel injector together with that tumble flow in the direction of the intake side roof, and an electrode of a spark plug projected from the intake side roof so as just to collide with the tumble flow. The thus constituted combustion chamber is able to establish fuel injection finishing timing over a wide range according to the fuel injection amount, when stratified charge combustion is applied.
