2013 MOTORCYCLE : ADVANTAGES AND DISADVANTAGES ENGINE TWO STROKE

ADVANTAGES AND DISADVANTAGES ENGINE TWO STROKE
Hello we meet again on the post empatlawang84.blogspot.com that constantly updates its news and of course the original by the author's own ideas and thoughts as I do not like TO COPY PASTE,
either at the first meeting for the writer discusses the advantages and disadvantages if we use a motorcycle engine 2 steps, as well as what specific characteristics on engines 2 steps ...

a. Advantages:
• The combustion process occurs every rotation of the crankshaft, so that the rotation of the crankshaft is more smooth for that rotation more evenly. Does not require valve, less spare parts, maintenance easier and relatively inexpensive
• Torque for another round shaft smaller resulting in a smooth motion
• When compared with the four-stroke engine the same capacity, the power generated greater
• The combustion process occurs 2 times, so more power
b. Disadvantages:
• Step incoming and exhaust shorter, resulting in loss measures the exhaust gas back pressure higher
• Due to the cylindrical sections have holes, arising friction between piston rings and piston rings as a result hole will wear faster.
• Because there are exhaust holes on the cylinder then heat will easily arise
• Low Round difficult to obtain
• Consumption of more lubricant.

Motorcycle engine that uses two steps Probably only marketed in indonesia:
- Yamaha
- Yamaha RX King
- Yamaha RX S
- Yamaha Alfa
- Tornado Suzuki GS
- Vespa Super
- Vespa PX
- Suzuki Tornado GX
General characteristics of two stroke the motorcycle engines:
- Lubricating system of gas mixed into the gasoline two stroke engine exhaust white enamelled
- A more refined engine sound as each two steps occur one  times burning gasoline
- More wasteful fuel consumption
- Using two lubrication function is to lubricate the space crank, pistons, and cylinder wall as well as to lubricate transmission.
- It has two piston rings, namely the first compression ring and The second compression ring.

Figure 1. Port timing diagram

The upward and downward movement of the piston will be open and close the intake hole, the hole transfer and exhaust located on cylinders, these events resolved diruang combustion (above the piston) and in the crankcase (under the piston). open and The closing hole is determined by the position and size of the hole. Open events and the closing of the holes is termed port timing ".
