Lexus Makes Revolutionary Move with RC F Model
How does the 2015 Lexus RC F deliver fire-breathing performance, but remain fuel-efficient at the same time?
The original Atkinson’s cycle was invented in 1882 by James Atkinson. At that time, Atkinson wanted to create a model for a more efficient internal combustion engine and his invention, although modified in some cases to include the Otto cycle, is still used today.
The Atkinson cycle is a four stroke process where a vehicle’s piston performs four separate strokes to complete a full thermodynamic cycle.
On the first motion, referred to as the intake stroke, the piston pulls air and fuel into the cylinder of the vehicle.
During the second motion or the compression stroke, the piston compresses the mix of fuel and air together, creating an explosive spark.
The third motion is the power stroke, where the force generated by the explosion moves the piston down the cylinder and in a final exhaust stroke, it expels the leftover mixture of fuel and air out through the exhaust valve.
Of course with the traditional Otto cycle engine, when the piston reaches the bottom of the power stroke, the cylinder pressure is still a good deal above atmospheric resulting in unused amounts of energy.
In a revolutionary move, Lexus merged the Atkinson cycle and Otto cycle together to create the ultimate engine: power and fuel economy.
The 2015 Lexus luxury model is constructed with a super robust 5-liter V8 engine. In order to power Lexus’ signature engine, the car maker uses the Atkinson cycle engine for city-like cruising conditions and when more thrust is needed, the Otto cycle immediately kicks in. This provides maximum fuel efficiency and
The RC F will have the best of both worlds. With more than 460 horses, this by far will be the most powerful Lexus engine to date. With 383 pound feet of torque, out the two together and that’s one mean driving machine.
