FG-VT9 V2 Engine & Parts

A V-twin or V2 engine is a two-cylinder internal combustion engine mounted in a lateral position or longitudinally. The engines are arranged in a V-shape with angles greater than 0 degrees but less than 180 degrees. Sometimes the cylinders can form a 90-degree angle twin engine, called an L-twin.

Advantages of V2 engine :

1. Good balance: Two cylinders balance the car engine, thereby reducing weight and improving car efficiency.
2. Excellent Air Cooling: Considering that the hot air from the four cylinder is directly discharged into the other cylinder, the V-twin engine has excellent cooling effect. Air-cooled and liquid-cooled engines work just fine.
3. Lightweight: Compared with other engines, the V-type engine is compact and light in weight.
4. Power/size ratio: V-twin is used in about 8.4% of large displacement motorcycles, cruisers and touring bikes due to its good power/size ratio. Having the two cylinders at a 90 or 180 degree angle helps balance the vehicle, making it smooth and easy to adjust for power.
5. Wide application: The V-type engine is small in size and can be widely used in motorcycles, small tractors, generators and other vehicles with limited space.
6. Legroom: The low-mounted V-twin creates more legroom and provides better handling than other bikes in its class.
7. Different variants: V-twin engines are available in different variants such as air-cooled and liquid-cooled, transverse, OHV, OHC and inline.
8. Increased speed: V-twin engines have two large pistons moving in equal and opposite directions. This allows them to spin at top speed, producing more peak torque and horsepower than similarly sized inline engines with four pistons.
9. Torque: The V-twin engine is very competitive, with more torque at the same rpm or lower. The V-engine has a relatively linear power output. High torque for easy access to engine power
10. Unique: The V-twin engine is narrow and helps keep the motors side-by-side by stacking the cylinders front-to-rear or keeping the transverse cranks. The engine is unique and easy to service.

Disadvantages of V2 Engine:

1. Slight vibration: V-twin, one cylinder is tilted horizontally and the other is tilted vertically, ensuring the balance of the motorcycle and reducing unnecessary vibration, which is a big problem with all V-twins.
2. Unbalanced Cylinders: If the angle of the cylinders is less than 90 degrees and not properly aligned, the engine will become unbalanced causing some vibration in the car.
3. Low horsepower: The V-twin engine makes the whole vehicle low in horsepower but high in torque. The intake speed of a V-twin engine tends to produce more peak horsepower.
4. Low fuel economy: Two engine cylinders therefore consume more fuel, be prepared to spend more on fuel.
5. Low horsepower: V-twins have lower power output compared to other V-engines.
6. Rough: While the engine might be great for some street bikes, many V-twins are rough in delivering power.
7. The valve train is loud: the valve train of the V-twin engine has a large friction loss, which affects the piston speed. Piston problems can also affect a motorcycle's ring reliability.
8. Distinctive Sound: The ignition change of the two cylinders of the V-twin makes the motorcycle have some unique sounds while driving.
9. Uneven firing: The 90-degree arrangement creates uneven firing intervals with the crankshaft firing at 270 degrees for the second cylinder. Restricted airflow to the rear cylinders: The configuration of the V2 engine results in uneven distribution of airflow, resulting in cooling problems in the rear cylinders.
