Automobiles are vehicles that drive people around. They are based on the internal combustion engine that was invented by a Dutch scientist in the late 1600s. William D. Packard, the founder of Packard Automobile Company, is pictured driving his Model B Packard near the company’s first plant.
Autonomous vehicles are a rapidly emerging technology, and are set to transform the way we live and travel. They will change the way we choose cars, plan our journeys, and perceive mobility. These new, advanced technologies will also change the act of driving itself. They will assist drivers and prevent accidents, but will also bring about a wide range of concerns and questions for consumers and policymakers.
Internal combustion engine
One of the oldest technologies used in automobiles is the internal combustion engine. Its inventor, Niklaus Otto, made the first working four-cycle internal-combustion engine in 1876. The engine was a great leap forward for transportation, cutting down on both time and costs. It competed with steam-powered cars and electric drive, but won out in the end. Over the next century, approximately 1.2 billion automobiles were produced, with a vast majority being powered by gasoline.
Automobile wheels are circular structures that rotate, supporting the car. They are located vertically under the vehicle and consist of several parts: the rim, the spokes, and the axle seat. The spokes are connected to the rim and plate by lug bolts. The spokes come in a variety of designs and play an important role in determining the weight of the wheel.
Vibrations in cars may have a negative effect on our sleep, according to a new study. Researchers at RMIT University in Australia found that vibrations produced by car seats make people drowsy. The vibrations are of low frequency and “steady.” Even healthy people can experience sleepiness from exposure to these vibrations.
Controls in automobiles allow the driver to customize the driving experience. For instance, a powerful navigation system may require more input from the driver than a simple audio system. This means that controls must adjust to the driver’s personality and environment.
The environmental impact of automobiles is a growing topic in public discourse. The industry is responsible for almost 30 percent of the nation’s greenhouse gas emissions, the highest proportion globally. However, it isn’t just cars that cause environmental problems. Planes, trains, and ships also contribute to emissions. Burning gasoline releases greenhouse gases, and as oil becomes harder to extract, these emissions will only increase. Fortunately, there are ways to reduce the environmental impact of transportation, and BMW is a good example of a carmaker trying to do just that.
