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 cavity in which the piston is placed in the block of an internal combustion engine. Is the piston movement of the track, in which the gas combustion and expansion, through the cylinder wall can also disperse part of the gas to the explosion of waste heat, so that the engine to maintain the normal working temperature.
Pneumatic actuator that converts pressure energy of compressed gas into mechanical energy. Cylinder has two types of reciprocating linear motion and reciprocating swing, as shown in The figure "Cylinder". Reciprocating linear motion of the cylinder can be divided into single acting cylinder, double acting cylinder, diaphragm cylinder and impact cylinder 4.
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.
