uously changing the compression ratio, which is a critical factor that determines thermal efficiency.  In a gasoline engine, the optimal compression ratio changes depending on the load conditions. However, with a conventional engine, because the pistons and crankshaft are connected directly by the connecting rod, the compression ratio is fixed. The VC-Turbo engine uses a multi-link system in place of a connecting rod to rotate the crankshaft, an...

of the piston by offsetting the centerline of the piston and the centerline of the crankshaft. Since the lateral thrust force of the piston during the power stroke is smaller than during the exhaust stroke, the center of the crankshaft is offset toward the anti-thrust side to lower the angle of the connecting rod, reducing friction during the exhaust stroke. The cylinder head is made of aluminum alloy, and the camshaft holder is made separate to ...

d for the Polo BlueGT in 2012. The system deactivates the lifting of the second and third cylinder camshafts so that their intake and exhaust valves remain closed to stop fuel supply to the engine. This does not reduce the frictional loss of relevant parts as the reciprocal motion of the piston and connecting rod is not interrupted. However, with the valves fully shut, the compression and expansion of the air in the cylinder merely causes the air...

pport (2) Natural Sound Smoother  The world's first technology to significantly reduce the knocking sound of diesel engines has been adopted in the Skyactiv-D 1.5 engine installed in the CX-3.  Mazda determined that the main cause of the knocking sound was the vibration of the piston when its connecting rod expands and contracts during combustion. Thus, they inserted the part (smoother) with a dynamic damper mechanism in the cylindrical pis...
