The internal combustion engine is operable with petrol as fuel and self-ignition, involving homogeneous charge compression ignition in a first range and external ignition in a second operating range. It has devices for adjustment of the control times of at...

The engine has a control device (6), automatically adjusted by actuator member (8) and connection element (9). The engine is elastically born in a frame (1). The actuator element is supported via the connection element on a frame-fastened abutment (10). Du...

The external ignition device includes an optical device in the path of a laser beam (12) from a laser source (11) with a focusing device (15), with at least one switchable mirror (17), preferably electrically operated, so that the laser beam can be selecti...

The engine has a combustion chamber (8), and an intake channel (7), and pref. an outlet channel (9) for gas flowing into the chamber, are formed as tangential channels. In the area of the intake aperture (2), the central flow line (7a) encloses an angle ( ...

The four-stroke engine has at least two inlet ports (4,5) leading to the inlet valves (2,3), the second port having a throttling device operated in dependence upon engine load. The throttling device (15), in the form of a flap or slide, to produce a define...

The method of running a spark-ignited internal combustion engine entails when under part load closing one of two inlet ports by a throttling device with a predetermined leakage opening, and opening or keeping open the other inlet port, and phase-displacing...
