Abstract: A two-stroke engine possesses a cylinder, in the cylinder bore of which a combustion chamber is formed. The combustion chamber is bounded by a reciprocating piston, which drives a crankshaft rotatably mounted in a crankcase. A crankcase interior is fluidically connected to the combustion chamber across at least one transfer channel in at least one position of the piston. The at least one transfer channel emerges with a discharge opening in the crankcase interior and with at least one transfer window on the cylinder bore. It is proposed that all transfer channels have an average length as measured from the discharge opening to the transfer window, the average length being at least 1.5 in relation to the stroke, and that the volume of the crankcase interior including all transfer channels is at most 3.1 in relation to the piston displacement.

Abstract: A mixed signal testing system capable of testing differently configured units under test (UUT) includes a controller, a test station and an interface system that support multiple UUTs. The test station includes independent sets of channels configured to send signals to and receive signals from each UUT being tested and signal processing subsystems that direct stimulus signals to a respective set of channels and receive signals in response thereto. The signal processing subsystems enable simultaneous and independent directing of stimulus signals through the sets of channels to each UUT and reception of signals from each UUT in response to the stimulus signals. Received signals responsive to stimulus signals provided to a fully functional UUT (with and without induced faults) are used to assess presence or absence of faults in the UUT being tested which may be determined to include one or more faults or be fault-free, i.e., fully functional.

Abstract: Method and system to configure a common set of electronic components using software in order to simulate different electronic, mechanical and/or electro-mechanical instruments or instrument functions. For each instrument function or traditional mode of operation to be simulated, software models are created which when directed to the electronic components, cause the electronic components to respond to input in the same manner that the actual, traditional physical instrument would respond to satisfy the same test requirement input. The software models are preferably stored in a model repository which is searchable to enable a user to select the instrument function or traditional mode of operation to be simulated with the corresponding model being provided to the electronic components. Once the model, i.e., a function for each synthetic element, is downloaded and the electronic components configured according to the model functions, testing of the assemblies or other UUTs can begin.
