Compression ratio is a very important term used for internal combustion engines. It is the ratio between the volume of the cylinder when the piston is at its bottom dead center and the volume of cylinder when the piston is at its top dead center. In essence, compression ratio defines the ratio to which a charge of incoming air-fuel mixture is compressed between the piston and cylinder head before combustion takes place. Once an engine is designed, its compression ratio is fixed for its lifetime, until now.
After 20 years of development, Nissan is finally ready to display a new four-cylinder turbocharged engine that can vary its compression ratio.
Now I know that you all think, what has Nissan to do with motorcycles… But not forget that Nissan has some interest in making a motorcycle. In 2014 Nissan revealed to friend and foe a 1500cc three-cylinder turbocharged motorcycle engine that was capable of producing 400cc horsepower and weighing only 40 kilograms. For comparison the average MotoGP engine delivers around 260 horsepower.
