3. Introduction II write car because for cars have interest, so I grow up the dream is very much invented car. I wrote to my car is in this article to know more cars. I want to say a car without invention, now the traffic will be very of mankind.

4. Who invented the car? IIn 1885 German engineer Carl. Benz in Mannheim had made a car, the car is three, two-stroke single cylinder with a 0.9 horsepower gasoline engine, with the basic features of modern cars, such as spark ignition, water cooled cycle, steel frame, leaf spring suspension, rear wheel drive, front wheel steering. It is generally regarded Carl. Benz tricycle made the first one born in 1885 as the year of car.

5. Why do cars burn oil? AA. Burn oil the main reason is the aging of valve oil seals or valve and catheter clearance is too large and the cylinder caused by excessive wear and tear. BB. When burning oil can lead to increased fuel consumption and power down the phenomenon.

6. How to diagnose car circuit? HHand-to-surface electrical components, according to the level of temperature for fault diagnosis, Electrical components work properly, you will have the right temperature, if temperature is too high, too low, would mean a failure. For example: starter able to operate, if the battery post and the wire very poor contact, touch and there will be a hot feeling; when the engine a small number of cylinders is not working or working poor, it can touch the spark plug outer surface of the cylinder temperature is low for the failure.

8. THE END II was divided into four paragraphs to write this article. One question is who is who invented the automobile, the two problems is to write Why use petrol vehicles, the three question is how to diagnose car circuit, the fours questions are How to open the most fuel-efficient car. Through each one paragraph I found many deficiencies in the car need to improve, but I still feel a very great human.
