Line engine, with all cylinders arranged side by side in a plane, has a simple cylinder block and crankshaft structure, and uses a single cylinder head. It has low manufacturing cost, high stability, good low-speed torque characteristics, low fuel consumption, compact size and wide application. Its disadvantage is low power. "In line" can be represented by L, followed by the number of cylinders is the engine code, modern cars mainly have L3, L4, L5, L6 engines.
The cylinder is composed of cylinder, end cover, piston, piston rod and seals, and its internal structure is shown in the "SMC cylinder schematic diagram" :
Hydraulic cylinder is a widely used structural form in hydraulic system. In order to correctly design and use this kind of cylinder, we should master its characteristics and related applications and precautions.
