Battery: this invention has made the complete car electric system possible. From the old heavy and unreliable ones to today's modern batteries, it's something that a car can't go without. In the invention of the batteries lay the seeds of today's modern electric-cars. Spark plug: today it's an usual item in car mechanics. But think of the people that invented it!! Lighting the fuel-air mix with an electric spark, simply amassing. How great it is, proves the fact that the principle is unchanged ever since. Every invention on the car has it's purpose and, in mechanical terms,it's own beauty. Ranking of this kind doesn't neglect all of the other marvels on the car, on the contrary. The genius in these 5 inventions is that they stayed basically unchanged for all of these years giving the driver comfort, safety and reliability
Light bulb: this invention is of course, revolutionary in all. The bulb replaced the gas-oil lamps which drivers hanged in the side of the car. Needless to say that it gave the driver the possibility of night driving thus more autonomy and safety on the road. The first bulbs that were used had a short life-span, but gradually built up to today ones that are enduring, long lasting and give us a comfortable night drive.
Car Battery Lifespan and What Causes Batteries to Fail. The average life expectancy of a car battery is three years or so, but there are several factors that can have an impact on that estimate. Even under the most ideal conditions, chemical reactions cause batteries to break down, and your vehicle will likely need a new battery within a few years. Though car battery problems are often associated with cold weather, Consumer Reports magazine says heat is a bigger enemy of car batteries and will take a bigger toll on performance and reserve capacity.
What are the signs and symptoms that might make you think your vehicle needs a tune-up? A misfiring engine (when spark plugs ignite at the wrong time) could be caused by worn or fouled spark plugs. Bad spark plugs can also cause low fuel economy, hard starting and sluggish acceleration. Most plugs, though, should last 100,000 miles or more, and engine computers do a remarkable job of compensating for worn plugs, so that might not be the main or only culprit.
