Sometimes camshaft lobes touch the rocker arm directly (as you see with overhead camshaft engines), thus opening and closing the valve. On overhead valve engines, the camshaft lobes don’t come into direct contact with the rocker arms, so pushrods or lifters are used.

It’s a thermo-setting plastic, which means it has a molecular structure that cross-links into very durable chains. And like other thermo-setting plastics, like polyurethanes, it remains pliable and resists oxidation and abrasion to a far greater degree.

When a lobe lifts one end of the rocker, the other end of the rocker presses down on the valve stem, opening the valve to let air in to the combustion chamber or letting exhaust out. It works sort of like a see-saw.

The solution is a set of diodes that serve as a kind of electrical check valve for current coming out of the alternator. Diodes only allow current to flow in one direction, so when AC goes in on one side, only DC comes out on the other.

Relays are used in high power devices and are essentially electrically activated switches. When you turn your car on, multiple components turn on like the fuel pump, computer and electric fans. A small amount of power is run through the switch in your ignition which can then activate multiple relays turning all the peripheral equipment without running full power for all of them through the ignition switch. Relays also can go bad over time and cause electrical problems. The best way to test a relay is to have a helper touch or listen to the relay while you turn the device on. You should feel a slight tap and hear a quiet click as the relay engages.

Part of the pin wraps around the bare wire, while another part clamps onto the insulation. This makes it harder to pull the wire away from the pin.
