Text for a video about cars. 150-170 words

It is necessary to write text for 10 videos on the topic of cars (how does a particular device work? Facts about cars? And everything else that gains a lot of views) with a length of 150-170 words. The style of the video is "talking head." Before writing the text for the video, provide topics for the video (for selection). The text should not be written by artificial intelligence, but it can be copied from articles on the internet. The text must constantly hold the viewer's attention. Deadline is 1 day. Payment is 20 dollars.

Here is an example of text for a video: 

"Why is it harmful to drive at low RPMs?

When operating at low RPMs, the engine does indeed consume less fuel, and the emission of harmful substances into the atmosphere decreases. 

This is why models with modern automatic transmissions (CVTs, multi-speed hydraulic automatics, and robots) are programmed to operate in this mode.

Fuel economy and environmental friendliness are certainly good, but when operating at low crankshaft RPMs, the engine is not being used in a gentle mode.

On the contrary — the power unit experiences much greater loads, which means its wear occurs faster. 

Thus, at low RPMs, the oil pump does not deliver full power, causing the crankshaft bearings to suffer from a lack of oil.

A shortage of lubrication is also observed in other components of the power unit (for example, the walls of the cylinders and the drainage holes of the piston rings), which leads to their faster wear.

If we are talking about a used car with a worn engine, then the pump itself already has insufficient performance. 

Due to increased clearances, oil leakage is much greater, so the pressure in the system "does not hold." 

Moreover, operating the car at low RPMs is fraught with increased wear of dual-mass flywheels. 

Meanwhile, this can turn into a very costly repair for the car owner.

For example, if the red zone on the tachometer starts at 6,000 RPM, then one should stick to a range of 3,000 to 4,500 RPM, and sometimes it is useful to rev the engine to the maximum. 

As for modern models with automatic transmissions, the sport mode can come to the rescue, in which the engine operates at slightly higher RPMs than by default.

Periodic activation of the sport preset will help increase the lifespan of the engine and the transmission itself."
