engine piston

Piston engine is a heat engine that uses one or more pistons move, which aims to convert pressure into a circular motion. Types of piston engines include: internal combustion engines, are widely used in motor vehicles; steam engine, used during the Industrial Revolution, and also the stirling engine.

Normally present in all types of piston engines

In piston engine possible presence of one or more number of pistons. These pistons located inside the cylinder. Inside the cylinder, the fuel mixture is inserted. This mixture can be gas that has been heat and pressure (such as the steam engine), or it could be gas heated in the cylinder with the ignition system. This hot gas that will eventually push the piston moves down and move the crankshaft.
In all types of machines, the downward movement of the piston is converted into circular motion, using the connecting rod and a crankshaft or swashplate. A flywheel is used for finer turnaround. The more cylinders in a piston engine generally also make the engine smoother. Power output of the engine piston is usually directly proportional to the total volume of the piston engine.

A seal is used between the moving piston and the cylinder wall so that the existing high pressure gas above the piston does not leak and does not reduce the efficiency of the engine's pistons. Seal is in the form of one or more piston rings. Ring is made of hard metal.

Usually machines are classified by the number of cylinders and the total volume of the cylinder. Cylinder volume is expressed in cubic centimeters (cc) or liters (l). Judging from the number of cylinders, the classification based on mode used. Internal combustion engine with one or two cylinders mostly used in the motor, while the car is usually put on the machine from 4 to 8 cylinders. A locomotive or ship typically has a number of cylinders at least 12 or more. Cylinder volume can vary from 10 cm ³ to tens of thousands of cm ³.
The capacity of the machine

For piston engine, the engine capacity was calculated from the total volume of all pistons inside the engine displacement for once. Usually the engine capacity is measured in liters or cubic inches or cubic centimeters (cc). Machine with a large capacity will usually be more powerful and greater torque at low speed, but also more extravagant gasoline consumption, although power output and fuel consumption is also much influenced by other factors.
