Do you really know these car safety knowledge?

From the perspective of ergonomics, the brake pedal and accelerator pedal must have a certain degree of recognition, and avoid accidentally stepping on the accelerator when stepping on the brake to ensure the safety of the people in the car. The brake pedal will be about 20mm higher than the accelerator pedal, which is a little uncomfortable, which plays a role in prompting the driver and preventing the wrong accelerator.

Do not step on the brake all the time when parking: keep stepping on the brake until the vehicle stops driving, which will have a relatively large impact in an instant. The skill is to release the brake once before the vehicle stops completely, and then gently brake until the vehicle stops driving.

Drinke driving is prohibited. Drunk driving accounts for 40% of the number of deaths in traffic accidents. According to the statistics of the American Automobile Association, there is a car accident caused by drunk driving every two minutes. So don't drink when driving, and don't drive when you drink.

What is the basics of automotive machinery?

1. The basic knowledge of automotive machinery is: strength: the ability of the material to resist plastic deformation and fracture under the action of external forces. Carbon steel: an iron-carbon alloy with a mass fraction of less than 14% of carbon and a small amount of impurity elements such as silicon, manganese, phosphorus and sulfur.

2. "National Higher Vocational College Teaching Reform Planning Textbook · Fundamentals of Automobile Machinery" is compiled in accordance with the spirit of the current teaching reform of higher vocational colleges. It is a professional technical course textbook for automobile application and maintenance, and the foundation for learning follow-up professional courses.

3. Mechanical basics is a comprehensive technical basic course. Through the study of this course, students can master certain knowledge of engineering mechanics, mechanical principles and mechanical parts, and lay the necessary foundation for the follow-up courses and related science and technology. ( I) Knowledge objectives Have the initial ability to abstract the actual simple engineering into a mechanical model.

4. In the car, there are mainly shafts in the transmission (input shaft, output shaft, intermediate shaft, second shaft, secondary shaft, etc., which depends on the transmission structure and gear position), as well as semi-shafts, transmission shafts, etc.

5. The good news is that everything in automobile machinery has a reason. This is just a matter of narrowing it down to the real problem. That's why mechanics and amateurs use on-board diagnostics (OBD) to help them find these problems quickly.

6. The objects of the basics of automobile machinery include mechanisms, connections, transmissions, materials, etc., and the engine mechanism is a part of it.

3 basic knowledge of automotive machinery

For some car maintenance, you might better give it to the mechanic, but you can do a lot of things in your own garage. Some tasks such as changing the oil or rinsing the coolant are good DIY projects, which can save a lot of money every year.In addition to regular maintenance, almost anyone can replace the headlight bulb or any taillight.

Cars are non-trackless vehicles driven by their own power units and with 4 or more wheels. In terms of its design and technical characteristics, passenger cars are mainly used to carry passengers and their carry-on luggage and/or temporary items, including the driver's seat, and the passenger car has no more than 9 seats.

The basic knowledge needed to learn automobile repair includes the following: First: automotive mechanical basics, circuit basics and mechanical drawing, etc. Second: If it is an imported car, we also need to master some professional English and basic English knowledge; in addition, we should carefully learn the professional knowledge of cars.

Basic knowledge of automobiles, basic main parameters of engines, automobileThe basic main parameters of the car engine include cylinder layout, maximum output power, engine cylinder number, maximum torque valve and displacement.

Engine position: horizontal, vertical. Generally, the front-wheel drive engine is arranged horizontally, and the rear-wheel drive and four-wheel drive are generally arranged vertically.

A must-have common sense for auto repair apprentices. The basic structure of a car consists of four parts: engine, chassis body and electrical equipment. The four-stroke gasoline engine is composed of a fuselage, crank connecting rod mechanism, gas distribution mechanism cooling system, lubrication system, fuel system and ignition system (the diesel engine has no ignition system), etc.

An animation is fully understood, intuitive automobile mechanical principle

First of all, the intake of the turbine chamber is connected to the engine exhaust manifold, and the exhaust port is connected to the exhaust pipe.Then the intake port of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. Finally, the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are rigidly connected.

The working principle of the four-stroke gasoline engine is to mix air and gasoline in a certain proportion into a good mixture. In the intake stroke, it is sucked into the cylinder. The mixture is compressed and ignited to produce heat energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a reciprocating linear motion, through the connecting rod, The crankshaft flywheel mechanism outputs mechanical energy to the outside.

As shown in the figure below, the timing mark of the Liberation CA6102 engine is "upper stop point/1~6". When this mark is aligned with the line on the flywheel shell, it means that the piston of 1~6 cylinders is in the upper stop point position.

There are three versions of the principle of Muniu Liuma, which are introduced as follows: Muniu Liuma is an ordinary unicycle cart.
