Graces Easy Guidelines To Understand When Shopping Online For Motorcycle Engines
There has been great technological innovations in the design of motorcycle engines. The biggest producers of motorcycles such as Suzuki, Yamaha, and Honda continue to put large amounts of money into research and development to produce the best performing engines for motorcycles.
Most major automobile manufacturers will admit that the leading edge of engine development is in motorcycles instead of aircraft or automobiles. Often the innovations applied to motorcycle engines migrate over the car engines. Better combustion is the key to all engine development. One of the newest innovations is the use of more than four valves per cylinder to create more flow area.
The movement of the motorcycle engine from the two valve models to four valve models was all about getting better combustion.
The introduction of the four valve engine by Honda in the 1960s allowed for narrow valve angles and shallow combustion chambers which gave good combustion when combined with a spark plug.
In the early 1980s Yamaha began to look beyond the standard four valve engine for new head and valve configurations to achieve better combustion. Some of the designs they looked used seven cylinders per valve. These models used three valves for exhaust and four for intake.
They finally found the performance they were after using five valves per cylinder. This design makes use of one extra intake valve giving more air flow at low to medium valve lifts.
This is right where most engines spend the majority of their operating time. One of the largest and most innovative producers of motorcycle engines in North America these days is Honda.
They have recently built a technologically advanced plant which makes more than half a million high tech engines each and every year. They use the most technologically advanced manufacturing processes with leading edge engine design to produce a premium product.
