Checking the Car Basics, Before Hit on the Road
When you turn the key and start your car, an electric motor (the starter) turns the crankshaft inside the engine. Rods connected to the crankshaft move pistons up and down inside hollow cylinders. At the same time, electricity is supplied to spark plugs mounted in the top of the cylinders. A mixture of gasoline and air is drawn into the cylinders and ignited by the spark plugs. The explosion forces the pistons down, in a designed order, turning the crankshaft. A fuel pump delivers gasoline from the gas tank to the carburetor. The carburetor mixes the correct amount of air with the gas being drawn into the cylinders, and the engine runs.
When you put the car in gear, the transmission moves the power from the engine down the drive shaft to the differential (rear end). The differential transfers the power to the axle that turns the wheels. Because of the extreme heat generated by the engine, the engine temperature is stabilized by a cooling system. (more…)
Changing the Auto Car Oil & Oil Filter
When you have your oil changed by professionals, they probably add a small charge to your bill to cover disposal of he old oil. Used oil is a hazardous waste. One pint of oil can contaminate 750 gallons of ground water. If you decide to change your car’s oil yourself, consider buying an inexpensive oil-change kit from an automotive store. These kits have basins into which you can drain the used oil; then you can take the basin to a collection center for recycling. Usually larger service stations take used oil.
Before changing your oil, run the engine a couple of minutes to warm the oil. Warm oil drains faster than cold oil.
