Compressed air cars are emission free. They also do not require a connection to the electric grid. A wind turbine or other renewable energy source can directly drive an air compressor or hydraulic pump. Compressed air cars do not rely on petrol stations or an electric grid. While centralized infrastructure might not be needed, it is an option.
The car, which was powered by two Rolls-Royce Spey jet engines that manufacture a combined 110,000 hp (82,000 kW) and 50,000 pounds (23,000 kg) of thrust, became the first vehicle to break the sound barrier on land. [31] [33] Jet-powered drag racing cars have also appeared in National Hot Rod Association (NHRA) events since the 1970s. [34]
Slovak designer Professor Štefan Klein began working on flying cars in the late 1980s. Having developed the AeroMobil, he left the company to develop a new idea as the AirCar, and set up Klein Vision with colleague Anton Zajac. [2] [3] The main fuselage of the AirCar doubles as a two-seat road car with four large road wheels.
Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds.
Inside the airbox of an Alfa Romeo Montreal Motorcycle airbox on a V-2 engine.. An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder.
Dry sump engines in some drag racing cars use scavenging pumps to extract oil and gases from the crankcase. [18] A separator removes the oil, then the gases are fed into the exhaust system via a venturi tube. [citation needed]. This system maintains a small amount of vacuum in the crankcase and minimises the amount of oil in the engine that ...
