In a modern
internal combustion engine, a mixture of air and gasoline are injected
into a cylindar through a pair of valves. After the gas/air mixture is
injected the valves close and the piston compresses the mixture which
is then ignited. This ignition forces the piston down the cylindar
which in turn applies a torque to the crankshaft. A second
pair of valves open allowing the exhaust to escape, and the process
repeats. The torque is transferred to the transmition, drivetrain and
then to the wheels which apply the force onto the ground using high
amounts of friction.
Torque is = to the force applied x the
length of the lever arm x the sine of the angle between the force
vector and the vector of the lever arm
This first video demonstartes the engine process in a four cylinder
engine, commonly found in small cars.
The engine powering
the Bugatti Veyron Super Sport is the same engine that can be found in
the original Veyron with various adjustments to improve performance. It
is a W16 (16 cylinder) engine with 8 cubic litres of capacity and 4
superchargers that force additional air into the engine. This results
in 1200 break horsepower and 1500 newton meters of torque.
Horsepower is a function of torque (foot-pounds) x 2 pi x rotations per
minute devided by a conversion factor of 33000
