20110068487 | Carburetor - A carburetor has a housing and an intake passage section disposed in the housing. A throttle element is arranged in the intake passage section and a choke element is arranged in the intake passage section upstream of the throttle element. At least one fuel opening opens downstream of the choke element into the intake passage section. A fuel valve controls a fuel quantity supplied to the at least one fuel opening. At least one auxiliary fuel port opens upstream of the choke element into the intake passage section. | 03-24-2011 |
20110146642 | Two-Stroke Engine, Sand Core for Producing a Two-Stroke Engine, and Method for Operating a Two-Stroke Engine - A two-stroke engine has a cylinder with a combustion chamber and a reciprocating piston for driving a crankshaft. Transfer passages connect the crankcase in at least one position of the piston with the combustion chamber and open by piston-controlled transfer ports into the combustion chamber. An inlet opens into the crankcase and an outlet is provided at the combustion chamber. The engine is dividable into four sectors parallel to a longitudinal cylinder axis. The transfer port of a first transfer passage is arranged in the first sector, the outlet is arranged in the second sector, the transfer port of a second transfer passage is provided in the third sector, and the inlet is arranged in the fourth sector. Within the cylinder the first and second transfer passages, at a spacing from a separation plane between cylinder and crankcase, pass together into one of the second and fourth sectors. | 06-23-2011 |
20110146643 | Two-Stroke Engine - A two-stroke engine has a cylinder with a combustion chamber and a piston reciprocatingly supported in the cylinder. A crankshaft is rotatably supported in a crankcase and driven by the piston. At least one transfer passage connects the crankcase in at least one position of the piston with the combustion chamber and has a piston-controlled transfer port that opens into the combustion chamber and an opening that opens into the crankcase. A mixture inlet opens into the crankcase. An outlet is provided at the combustion chamber. The transfer port and the opening are displaced relative to each other in a circumferential direction of the cylinder. At least one wall section of the transfer passage forms an undercut when viewed from the crankcase in a direction of a longitudinal cylinder axis of the cylinder and is delimited by a separate component inserted into the cylinder from a side facing the crankcase. | 06-23-2011 |
20120304973 | Two-Stroke Engine - An engine has a cylinder wherein a reciprocating piston is mounted. The piston drives, via a connecting rod ( | 12-06-2012 |
20130263812 | Internal Combustion Engine - An internal combustion engine has a cylinder liner arranged in the cylinder. A piston moves reciprocatingly in a direction of the longitudinal cylinder axis in the cylinder and is guided within the cylinder liner across a section of a movement path of the piston in the cylinder. A combustion chamber disposed in the cylinder is delimited by the piston. In a crankcase, a crankshaft is rotatably supported by a crankshaft bearing, wherein the crankshaft is driven in rotation by the piston about an axis of rotation of the crankshaft. A position of the cylinder liner relative to the crankcase is secured with form fit by a securing element located at an end face of the cylinder liner that is facing the crankcase. No loads are transmitted into the cylinder liner from the crankshaft bearing through the end face of the cylinder liner that is facing the crankcase. | 10-10-2013 |

20160069296 | TWO-STROKE ENGINE - A two-stroke engine has a cylinder with a combustion chamber formed therein. The combustion chamber is delimited by a piston. The cylinder has a base on which extends a partition plane whereat the cylinder is separated from a crankcase. The combustion chamber is, in at least one piston position, connected via at least one transfer channel to the crankcase interior. The transfer channel passes from the cylinder into the crankcase at at least one opening. A side wall of the transfer channel has, in the cylinder, a first region wherein the wall encloses an angle of 90° with the cylinder longitudinal axis. Between the first region and the opening as viewed in the cylinder circumferential direction is arranged a second wall region. The second region has a spacing, measured parallel to the cylinder longitudinal axis, to the partition plane. The spacing is greater than the spacing in the first region. | 03-10-2016 |
