1. The major systems of the automobile are the power plant, the power train, the gear, and the control system.
2. The advantage is that valves are operated almost directly by the - easy to achieve the perfect timing at high rpm.
3. A tension spring can be wound with initial pre-load so that it deforms only after the load a certain minimum value.
4. Lead-acid batteries have been around since the earliest days of the automobile and have steadily over the years.
5. The spiral-wound cells also produce a slightly higher voltage that raises the battery's overall voltage output by 15 percent for added power.
6. To minimize the risk of such damage, most vehicle manufacturers recommend replacing OHC timing belts at specific mileage intervals for preventive .
7. Most performance pipes are formed with mandrel bends which do not the diameter of the pipe where it curves.
8. Most vehicles will lose a little coolant over time to evaporation from the reservoir.
9. The most vulnerable components are the radiator and heater core, especially lead-soldered copper/brass exchangers in older vehicles.
10. There's a wide range of friction materials used in brake linings today including semi-metallic, ceramic, and non-asbestos organic.
