How to Decide On Your Very First Race Car (Part 2)
Now that the park, reverse, neutral, and drive is covered, it is time to take a look at the rest of the gears in an automatic gearbox, as well as manual, different fuels, and differences in the wheel drive of cars.
One common question that drivers have about automatic transmissions is: why does my car move forward when in drive? Quite simply, the engine is running, and when the selector is in drive, it is always in gear. At low engine rotations per minute (RPM), the
torque converter allows slippage. This means that brakes will be sufficient in keeping the car from rolling forward. However, at higher RPM, the brakes will not be able to keep the car from moving, resulting in a burnout.
Although it is not recommended, it is easy to prove this in an automatic car. Drivers will notice that when their car is in gear, brakes keep it from rolling forward, and when you let go of the brakes, the car will slowly roll. If you press the brake slightly,
slowly depress the accelerator, then press the brake and gas full, then you will notice that there is no slippage, and your car’s wheels will start spinning on spot. If the engine RPM were higher, then this would happen every time you stopped and applied the
brakes while in gear.
Be thankful. Doing burnouts is dangerous and has a very negative, harsh effect on the engine.
The “2” below the drive quite simply keeps the car in the first two gears. “1” or “L” will keep the car in first gear for towing or slopes.
Now that auto cars are done, it is time to take a look at manuals.
A manual car is pretty simple. According to the RPM shown in the tachometer, you change the gear to prevent the car’s engine from working too hard or too less. For example, you should not drive in first gear until 8000 RPM and should not drive in your fifth
gear at only 2000 RPM at low speeds. Doing both is bad for your engine and should be avoided.
An automatic car has an automatic clutch, which shifts gears as necessary. In a manual, you need to press to clutch to change gears, and press the gas as much as you let go of the clutch to keep the car from stalling. It takes a bit of practice, but it’s
easy to learn.
The manual shifter, also known as a “stick,” is, well, a stick. It comes up where the automatic shifter usually is and instead of moving down, has gear numbers on it, and an “R” for reverse. The allocation of the gears is indicated on the top of the shift
k**b, which is the part where you grip the stick from. That’s why manuals are sometimes called “stick shifts.”
For normal driving, an automatic car is preferable. It is easy to drive in traffic, and is relatively effortless. On the other hand, a manual is more difficult to drive, but it is a lot of fun. Manual are usually used for towing, racing, or those who drive
on slopes often.
Now that the differences between automatic and manual gears have been covered, it is time to take a look at the different types of fuel used to power the vehicle. The most common type of fuel is petrol, or gasoline, and diesel.
The main difference between a petrol and diesel engine is that diesel engines do not have spark plugs. When the air is compressed in the chamber and diesel added, it ignites. That is the simplest of differences. Aside from that, old diesel engines are loud
and noisy, although changes in newer ones make them quieter.
Diesel engines are also much dirtier. Although they give better gas mileage, they are more harmful to the environment because they produce soot, which is produced from incomplete combustion.
Other forms of engine fuels and the wheel drive of cars will be discussed in the next article.
