The workings of a 4 stroke engine itself there are four stages, namely:
1 Suction,
2 Compression,
3 Enterprises,
4 Discard,
The first, which has a negative pressure piston (moving from top to bottom) haze suck gasoline into the combustion chamber ..
second, the piston rises back up and create pressure ..
Third, the spark plug sparks when the air pressure reaches the combustion condition ..
Fourth, the combustion discharged into exhaust / exhaust ..
advantages:
-Because Entry process, compression, work, and dispose of stand-alone process that is more precise, efficient and stable, round distance from low to high is wider (500-10000rpm).
- Losses due to back pressure step is smaller than the two stroke engines that use less fuel.
- The low round of better and more engine heat can be cooled by circulating oil
- Step intake and exhaust is longer so that the efficiency of income and the average effective pressure better
- The heat engine is lower than the two-cycle engine
disadvantages:
- Components and more valve motion mechanism, so that the treatment is more difficult
- Voice over rowdy mechanical
- Step 2 rounds of work going on with the crank shaft, so turn the balance is unstable, need more than the number of cylinders and as a vibration damper
General characteristics of 4 NOT:
- Exhaust gas is colorless (except for damage)
- More fuel efficient
- Using a lubricating oil to lubricate the space crank, piston, cylinder walls and transmission
