Repair And Fix it

A gasoline internal combustion engine combines a mist made of air and fuel in its intake manifold. When the intake valves open, a spark plug fires to ignite this mixture, pushing the piston downward to turn the crankshaft. The revolution of the crankshaft pushes the next piston up, and the process repeats to continue the rotational motion.

The transmission connects to the engine via a torque converter or a clutch plate or plates, depending on the type of transmission. Power from the engine turns the input shaft and then transfers through the transmissions gears to attain the desired output ratio.

In some cars, the differential bolts directly to the transmission in a single housing. In others, it mounts on the rear axle and connects to the transmission via the driveshaft. The differential is responsible for flipping the rotational motion of the driveshaft onto the separate axis of the axle turning the wheels.

When fuel is burned in your engine, waste gases are created. These harmful gases exit the engine through an exhaust manifold, which ties into an exhaust pipe to carry them away. Modern cars with fuel injected engines have oxygen sensors to monitor how much fuel is added into the engine for it to function properly. As new fuel is injected and burned, the waste gas that is created is flushed from the car via the exhaust pipe.

The gas created in the engine can cause brain damage or even death if inhaled, so the exhaust system is designed to remove it without exposing you to the fumes. The exhaust pipe is designed so all toxins are flushed out and away from the car.

It is important to have your exhaust system monitored frequently. Corrosion is a common problem in exhaust systems and holes can allow dangerous fumes to get into your car, harming you and your family. Also, if exhaust gases back up into the combustion area, they can cause damage to your engine.
