Seafood is a staple in nearly every Chilean's diet. Shellfish such as loco (abalone), erizo (sea urchin) and piure (an unusual red invertebrate) join more widely known fish, including sardines, salmon, congrio (conger eel) and atÃºn (yellowfin tuna).
To work efficiently, pipes need a way of regulating how much fluid can pass through them; they also need a way of switching the flow off completely. That's the job that valves do: valves are like mechanical switches that can turn pipes on and off or raise or lower the amount of fluid flowing through them.
How do camshafts and valves work? The differences between DOHC, SOHC, and OHV or pushrod valve trains is explained. How the valves are related to each, and how each works. I will also speak of advantages of each of the valve trains. Dual overhead cams (DOHC), singles overhead cams (SOHC), and overhead valves (OHV).
