Mazda launched the Cosmo Sport in 1967 as a demonstration of reliability. The engineers perfected the seals at the tips of the rotor to prevent the leakage of gases from the chambers. This engine produced power from a displacement of 982 cubic centimeters. Honestly? It's not that simple because the consumption of fuel remained a challenge for the owners who drove the car in the city. The vehicle weighed 940 kilograms.
Honda engineers utilized the NSX to prove that a supercar could function as a transport for a person every day. The design of the cabin took inspiration from the canopy of a jet. Ayrton Senna insisted that the chassis required more stiffness to handle the forces of the track at Suzuka. The team added thickness to the sills of aluminum and the bulkhead of the engine. This change improved the lap times.
The 1997 Prius utilized a device of gears to combine the torque from the engine and the motor. This link allowed the car to operate as a series hybrid and a parallel hybrid. Efficiency reached 28 kilometers for every liter of gasoline. The screen in the center of the dashboard showed the flow of energy between the wheels and the battery. This car changed the way a person perceives the consumption of energy.
The Skyline GT-R R32 utilized the RB26DETT engine with two turbochargers and six cylinders. The system for steering moved the rear wheels in the same direction as the front wheels during a turn at high speed. This increased the stability of the vehicle. The car won 29 consecutive races in the Japanese Touring Car Championship before the officials changed the rules to exclude the technology. Godzilla dominated the pavement.
The LFA project started as a study in aluminum but moved to plastic reinforced with carbon fiber to save weight. Only 500 units left the factory floor in Motomachi. The tachometer was a screen of liquid crystals because the engine could rev from idle to 9000 rotations in 0.6 seconds. A needle of metal would break from the force. Yamaha engineers crafted the sound of the exhaust to match the pitch of music.
Subaru utilized a layout of symmetry for the drivetrain to ensure that the weight was distributed on the left and right sides. The movement of the pistons in opposition canceled out the vibrations. This allowed the engine to sit in a position near the ground. The car gripped the gravel of the rally stages and won three titles for the manufacturer.
Extra Perk
Japanese manufacturers entered an agreement to limit the power of cars to 276 horsepower. This pact aimed to improve safety on the roads. Engineers followed this rule until 2005. To be fair, many engines produced more power than the documents stated. This led to a culture of modifications among owners who wanted to see the capability of the machinery. Modern factories now utilize the "Kanban" system to manage the inventory of parts and electronics and furniture. This method ensures that a factory receives components exactly when they are needed for assembly.
Did anyone ever explain
The triangle in the Mazda engine is a Reuleaux triangle. This shape rotates around an eccentric shaft while the points of the triangle maintain contact with the walls of the housing. This motion creates three chambers that change in volume to complete the cycles of intake and compression and power and exhaust. The design provides three power strokes for every single rotation of the rotor. The Power Split Device in a hybrid acts as a brain for the system. It consists of a planetary gear set that connects the engine and the generator and the electric motor. By varying the speed of the generator the system changes the ratio of the gears without a traditional transmission.
