The two states of the valve are open and closed. When the valve is open, air flows from the inlet (P, 1) to the outlet (A, 2). When the valve is closed, air flows from the outlet (A, 2) to the exhaust (R, 3). A valve that is closed in its non-actuated state is called...
DeLuxes were again fully restyled for 1939, bearing a lower Vee'd vertical-bar grille and clean front fenders with integral headlamps. As in recent years, this styling was created by E.T. "Bob" Gregorie under Edsel Ford's guidance. By contrast, that year's Ford Standards looked like wa...
So the two or so gallons of coolant that circulate within the typical automotive cooling system have to carry away a lot of heat. The radiator also has to be fairly efficient at getting rid of the heat, too, otherwise the BTUs will start to back up and make the engine overheat. An ef...
Especially, modern-day compact cars have little space in the engine compartment. Hence, manufacturers fit very tiny and compact exhaust systems and manifolds in these cars. In addition, manufacturers design exhaust manifolds to avoid overlapping exhaust strokes as much as possible. Thus, it keeps th...
"How to clean carbon build up on intakes" All engines burn fuel and carbon or sooty deposits are a natural occurrence, but over time this can cause problems as the carbon layer builds up. It will restrict air flow into the engine, can create unsual air flows into the cylinders that preve...
This was the first version of the Panther, the version so bad it would light on fire if the hull got tilted too much, no joke because the fuel system leaked into the rubber lined engine compartment and when the hull tilted, fuel would hit the ...
The twincam Zetec engine, for example, was lifted to 170 bhp via new pistons, revised cylinder head, variable intake-valve timing, and new intake and exhaust manifolds. Also on the menu were a mandatory new six-speed manual gearbox, firm suspension with 17-inch wheels, and larger four-...
