This answer is from my own past experiences. It is not guaranteed, but it has helped me and friends in the past. I have found that the wipers are sometimes incorrectly adjusted, somtimes due to years of use/adjustment slippage. The wiper motor drives the wipers with a drive arm. The actual wipers themselves are attached to this drive arm with a screw. If the wipers are hitting the park-stops on every wipe, the adjustment screw needs adjusted. Basically, turn the wipers off. Here is where it gets a bit tricky. The bottom part of the windshield, where the wipers recede, there may be a screw to open an access plate (probably plastic) where you can lower a nut driver (same as a screw driver, but with a socket end on it) and loosen the bolt below. God, this is hard to explain on a simple internet text message. Now, with the wipers off, and the screw loosened, manually move the wipers to their normally parked position, probably a very slight move. Now, lock that screw/bolt down. Tighten it and try the wipers once again. If the problem is still present, then the main bolt on the wiper motor itself needs loosened, repositioned, and tightened.
the power stroke is the downward stroke of the piston, how much power is created in this motion is judged in horse power.
The shut height is the outside dimension of the die set (measured from the bottom to the top die plate) when the press ram is at the limit of it's downward stroke (in the case of a vertical press).
You use two fingers and stroke downward on the mouse pad to scroll down and to go up you stroke upward.
it is called a smash
Cracked head or leaking gasket. The suction is created on the downward stroke of piston during intake stroke.
While there may be some overlap of valve opening timing, generally speaking, the exhaust valve opens after the power stroke, and the intake valve opens after the exhaust stroke. Recap... We start the combustion cycle of a standard 4-stroke engine with the intake stroke, the intake valve is open and the vacuum created by the downward movement of the piston draws in the air/fuel mixture from the intake manifold. The intake valve closes as the piston rounds bottom dead center and the compression stroke begins on the upward movement of the piston. At or near the top of the compression stroke, the spark plug fires (both valves are closed at this point) and begins the downward power stroke. As the piston rounds bottom dead center again, the exhaust valve opens to allow the piston to push out the exhaust gasses during the upward exhaust stroke. As the piston gets to the top, the exhaust valve closes and the intake valve opens to start the process over again.
The power stroke. The order is intake, compression, power and exaust. The piston moves down on intake and power but is only forced down on the power stroke
Stroke
The 4 cycles represent the strokes that the piston makes as it travels up and down the engine cylinder. Generally considered to be the first cycle (stroke) is the downward stroke commonly referred to as the intake stroke because during that stroke it pulls a mixture of air and fuel into the cylinder. The following (2nd) stroke is called the compression stroke because it compresses the air and fuel mixture as the piston travels upward. As the piston approaches the top of it's travel on the compression stroke, the spark plug (in gasoline fired engine) is energized by an electrical charge causing a spark to jump across the 'gap' of the spark plug. This spark ignites the fuel and air mixture. The resultant 'explosion' then drives the piston downward on the 3rd stroke which is called the power stroke. When the piston reaches the lowest point of its downward travel, the exhaust valve opens and the movement of the piston upward on its 4th cycle (aka Exhaust stroke) pushes the burnt gas mixture out of the cylinder into the exhaust system and the 4 cycles begin all over again. Because the bottom of the piston is attached to the crank shaft it causes the crank shaft to rotate. This rotation is transmitted to whatever mechanical need the engine is to supply. On a car, it turns the wheels. On a lawn mower it turns the cutting blade.
Salut: With an open hand/fingers together, stroke the cheek downward, then bring the hand from above the head and downward in front of the face. As with many signs this is a compund sign, and is, actually, feminine god.
One sign of a stroke could be a the person's speech is slurred or strange. Another sign is that one side of their face is drooping. The last sign is one arm dropping downward.
cc=cubic centimeter= displacement=the amount of area displaced between the bottom of the stroke and top of the stroke of the piston.
