| 摘要 |
The invention relates to a method for optimizing an internal combustion engine with variable compression ratio for a direct start, the engine comprising a crankcase comprising a crankshaft connected to at least two pistons; and a cylinder block comprising at two cylinders The method involves determining a crank angle adjustment required to achieve a crank angle suitable for ignition in a first cylinder and operating at least one actuator (223; 423) to displace the cylinder block relative to the crankcase for adjustment of compression ratio and cylinder offset (O). This causes a simultaneous displacement of the cylinder block (217) in the direction of the cylinder axis (Y), and transverse to the cylinder axis (Y) and the crankshaft axis (X). The crank angle adjustment is performing using a mechanism (428; 528; 430) connecting the cylinder block and the crankshaft, which mechanism (428; 528; 430) is actuated by the cylinder block displacement. |
