When you depress your brake pedal, your car transmits the force from your foot to its brakes through a fluid. Since the actual brakes require a much greater force than you could apply with your leg, your car must also multiply the force of your foot. It does this in two ways: Mechanical Advantage and Hydraulic Force Multiplication. The brakes transmit the force to the tires using friction, and the tires transmit that force to the road using friction also.
If you’ve ever heard a car engine running without a muffler, you know what a huge difference a muffler can make to the noise level. Inside a muffler, you’ll find a deceptively simple set of tubes with some holes in them. These tubes and chambers are actually as finely tuned as a musical instrument. They are designed to reflect the sound waves produced by the engine in such a way that they partially cancel themselves out.
Located inside the muffler is a set of tubes. These tubes are designed to create reflected waves that interfere with each other or cancel each other out. The exhaust gases and the sound waves enter through the center tube. They bounce off the back wall of the muffler and are reflected through a hole into the main body of the muffler. They pass through a set of holes into another chamber, where they turn and go out the last pipe and leave the muffler.
A chamber called a resonator is connected to the first chamber by a hole. The resonator contains a specific volume of air and has a specific length that is calculated to produce a wave that cancels out a certain frequency of sound.
The ignition system on your car has to work in perfect concert with the rest of the engine. The goal is to ignite the fuel at exactly the right time so that the expanding gases can do the maximum amount of work. If the ignition system fires at the wrong time, power will fall and gas consumption and emissions can increase.
When the fuel/air mixture in the cylinder burns, the temperature rises and the fuel is converted to exhaust gas. This transformation causes the pressure in the cylinder to increase dramatically and forces the piston down.
The main job of the fuse is to protect the wiring. Fuses should be sized and located to protect the wire they are connected to. If a device like your car radio suddenly draws enough current to blow the fuse, the radio is probably already toast. The fuse is there to protect the wire, which would be much harder to replace than the radio.
Most cars have two fuse panels. The one in the engine compartment holds the fuses for devices like the cooling fans, the anti-lock brake pump and the engine control unit — all of which are located in the engine compartment. Another fuse panel, usually located in the dashboard near the driver’s knees, holds fuses for the devices and switches located in the passenger compartment.
The most foolproof way to check a fuse is to pull it out of its receptacle and hook up a continuity tester to both blades of the fuse. Economy Transmissions can help you check your fuses fast and easy!
