Basic engine parameters
Number of cylinders: 3, 4, 5, 6 and 8 cylinders are commonly used in automobile engines. An engine with a displacement of less than 1 liter generally has three cylinders, an engine with a displacement of 2.5 liters generally has four cylinders, an engine with a displacement of about 3 liters generally has six cylinders, an engine with a displacement of about 4 liters has eight cylinders, and an engine with a displacement of more than 5.5 liters uses 12 cylinder. Generally speaking, under the same cylinder diameter, the more cylinders, the greater the displacement and the higher the power; Under the same displacement, the more cylinders, the smaller the cylinder diameter and the higher the rotation speed, thus obtaining greater lifting power.
Cylinder arrangement: Generally, the cylinders of engines with less than 5 cylinders are in-line arrangement, and a few 6-cylinder engines also have in-line arrangement. The cylinder block of an in-line engine is arranged in a straight line. The cylinder block, cylinder head and crankshaft are simple in structure, low in manufacturing cost, good in low-speed torque characteristics, low in oil consumption, compact in size and widely used. The disadvantage is low power consumption. In-line 6-cylinder has good dynamic balance and less vibration. Most engines with 6 to 12 cylinders are arranged in V-shape, that is, the cylinders are arranged in four staggered angles, which are compact in shape and very small in length and height, so it is very convenient to arrange. V8 engine is rarely used because of its complicated structure and high manufacturing cost. The V 12 engine is too big and heavy, and only a few luxury cars use it.
Number of valves: most domestic engines use two valves per cylinder, namely an intake valve and an exhaust valve; Foreign automobile engines generally adopt a four-valve structure per cylinder, that is, two intake valves and two exhaust valves, which improves the intake and exhaust efficiency; Some foreign companies began to adopt the structure of five valves per cylinder, namely three intake valves and two exhaust valves. The main function is to increase the air intake and make the combustion more thorough. The number of valves is not as large as possible. The five-valve can really improve the intake efficiency, but the structure is extremely complicated, the processing is difficult, and it is used less. The new Jetta King produced in China uses a five-valve engine.
Displacement: The working volume of the cylinder refers to the volume of gas swept by the piston from top dead center to bottom dead center, also known as single cylinder displacement, which depends on the cylinder diameter and piston stroke. Engine displacement is the sum of the working volumes of each cylinder, which is generally expressed in liters (L). The engine displacement is one of the most important structural parameters, which can represent the size of the engine better than the cylinder diameter and the number of cylinders. Many indexes of the engine are closely related to the displacement.
Maximum output power: The maximum output power is generally expressed in horsepower (ps) or kilowatt (kw). The output power of the engine has a great relationship with the speed. With the increase of speed, the power of the engine increases correspondingly, but after a certain speed, the power tends to decrease. Generally, the maximum output power is expressed by the speed per minute (r/min) in the automobile manual, such as 100ps/5000r/min, that is, the maximum output power at 5000rpm is100hp.
Maximum torque: the torque output by the engine from the crankshaft end. The expression of torque is N.m/r/min. The maximum torque generally appears in the middle and low engine speed range, but it will decrease with the increase of engine speed. Of course, when choosing, we should weigh how to use it reasonably and not waste existing functions. For example, air conditioning should be turned on in Beijing in winter and summer, and the engine power should not be too small when choosing; Just commuting on the city loop, there is no need to pick an engine with too much horsepower. Try to match the engine economically and reasonably.
5v: V is the initial letter of "value" in English. The traditional automobile engine cylinder generally adopts four-valve structure, that is, two intake valves and two exhaust valves, which ensures full and effective intake and exhaust, is conducive to the improvement of engine speed, and thus achieves the maximum power of the engine. At present, the 5-valve technology has been widely used in foreign automobile companies. Bora, which was recently listed in China, adopted five-valve technology, namely three intake valves and two exhaust valves. Volkswagen is a leader in the application of 5 valves.
ABS is the abbreviation of "anti-lock braking system" in English, which is translated into "anti-deadlock braking system" in Chinese. It is a safe braking control system with the advantages of anti-skid and anti-lock braking. In case of emergency, a car without ABS system has no time to slow down step by step, so it can only be trampled to death. At this time, the wheels are easy to lock up, and with the sprint inertia of the vehicle, there may be dangerous situations such as sideslip, deviation and out-of-control direction. On the other hand, when the car equipped with ABS is about to reach the next locking point, the brake can act 60 to 120 times in one second, which is equivalent to continuous braking and relaxation, similar to mechanical "point braking". Therefore, it can avoid the out-of-control direction and wheel side slip during emergency braking, so that the wheels do not lock up during braking, and the tires do not rub the ground at one point, which increases the friction force and makes the braking efficiency reach more than 90%.
GPS is the abbreviation of Global Postioning System, and its main functions include anti-theft function, anti-robbery function and navigation function.

1, ESP is the abbreviation of English ElectronicStabilityProgram, which is translated as "electronic stability program" in Chinese.
2.ABS is the abbreviation of anti-lock braking system, which can be translated as "brake anti-lock braking system".
3. EBD-electronic control braking force distribution system
4.ASR is the abbreviation of driving acceleration slip regulation. Its function is to prevent the driving wheel from slipping during auto start and acceleration, especially to prevent the driving wheel from idling when the car is on asymmetric road or turning, and to control the slip rate within the range of 10%-20%. Because ASR is mostly controlled by adjusting the driving force of driving wheels, it is also called driving force control system, which is called TCS for short, and TRC or TRAC in Japan and other places.
5.GPS (Global Positioning System) is a new generation of satellite navigation and positioning system, which was developed by the United States in the 1970s. It took 20 years and cost 20 billion dollars. 1994 is fully built, and it has all-round real-time three-dimensional navigation and positioning capabilities by land, sea and air. After nearly 10 years of application in China's surveying and mapping departments, it shows that GPS has won the trust of the majority of surveying and mapping workers with its remarkable characteristics of all-weather, high precision, automation and high efficiency, and has been successfully applied to geodesy, engineering survey, aerial photogrammetry, vehicle navigation and control, crustal movement monitoring, engineering deformation monitoring, resource investigation, geodynamics and other disciplines, bringing a profound technological revolution to the field of surveying and mapping.
6.OBD is the abbreviation of English On-Board Diagnostics, and Chinese translation is "on-board automatic diagnostics system". This system will monitor whether the automobile exhaust exceeds the standard at any time from the running condition of the engine, and once it exceeds the standard, it will immediately issue a warning. When the system fails, the MIL lamp or the engine inspection warning lamp lights up, and the powertrain control module (PCM) stores the fault information in the memory, and the fault code can be read out from the PCM through a certain program. According to the prompt of fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.
7、WAAS
Tracking performance is also the accuracy of wide-area enhanced differential GPS. The explanation of wide-area enhanced differential GPS is as follows: Wide-area enhanced differential GPS(WAAS) is developed from WAGPS. Functionally, it provides users with perfect broadcasting, differential correction signal and additional ranging signal. In this system, the ground reference station uses a GPS receiver to monitor the GPS signal. And sends the monitoring data to the main control station. The main control station calculates the position correction value and its validity. Then send the data to the GPS receiving user through the satellite.
The fundamental difference between WAAS and DGPS lies in:
In the 1. error processing method, the main control station separates the spatial correlation and calculates the ephemeris error, satellite clock error and atmospheric propagation delay error respectively to improve the positioning accuracy.
2. The message broadcast by the main control station contains complete information besides the modified data. This message is modulated on the L 1 frequency of GPS, which enables communication satellites to provide ranging, increases the number of satellites in the GPS constellation, and improves the availability and continuous service of the system.
3. The user equipment does not need to establish another RF receiving part of the data link, but only needs to leave a receiving channel for the GPS receiver and add a WAAS message extraction and processing program.
8. The so-called MFI, which means multiple fuel injections, is a mature engine technology.
9. Daylight Saving Time
Generally speaking, the so-called DST coordinated power system is not a technology, but on the basis of adopting a variety of advanced and mature engine technologies, through careful matching and intelligent control system, all parts of the engine system are guaranteed to cooperate organically in the dynamic driving environment of vehicles, and the overall energy efficiency is maximized.
10、MPV
The concept of "Mini Passenger Van" comes from the United States, which is the abbreviation of Mini passenger van. The original meaning is mini passenger car (the "mini" here mainly refers to large trucks like passenger cars). Later, someone changed it into a multi-purpose vehicle, emphasizing its versatility. It's a car, a station wagon and a van. But today, any car called MPV must be a van, which is also commonly known as a van. It must be used to carry passengers.
1 1, CKD (complete disassembly) all loose parts.
CKD is a proper term for imported vehicles in the form of vehicle parts. Parts produced locally are assembled into complete vehicles, with lower tariffs and wages, and lower retail prices.
12、RV
The full name of is RECreative &；; Vehicle is an entertainment vehicle, which is suitable for entertainment, leisure and travel. Japan was the first country to put forward the concept of RV. RV covers a wide range and there is no strict category. Broadly speaking, all light buses except cars and sports cars can belong to RV. MPV and SUV also belong to RV.
13、ECU
It is the abbreviation of English word combination, which means "electronic control unit", which is simply a car computer. At present, many automobile engines mostly use electronic fuel injection system, and one of the control components shaped like a square box is called "ECU". Simply put, ECU is composed of microcomputer and peripheral circuits. A microcomputer is a device that integrates a microprocessor (CPU), a memory and an input/output interface on one chip.
14、BA
brake assist system
During emergency braking, the braking system will automatically sense and output stronger braking force according to the speed and intensity of pedaling.
1. When braking in critical state, the braking force output is sometimes very small due to its high speed and low pedaling force.
2. At this time, the driver should not step on the brakes all the time, which may lead to the reduction of braking force.
3. "BA system" automatically judges whether to brake urgently when stepping on the brake quickly, even if the force is not enough, it will increase the braking force output.
4. "BA system" automatically reduces the auxiliary braking force when consciously braking, and slows down the sudden feeling when braking.
1, valve: a valve that controls air intake and exhaust (just like a person's mouth and anus).
2. Cylinder: the working space for fuel combustion (just like human lungs and chest).
3. Torque: the ability to overcome the rotational resistance. The former number refers to the maximum traction, and the latter number indicates the engine speed when the maximum traction is output (just like the explosive force generated by running).
4. Power: generally refers to the output power of the engine. The former figure refers to the maximum horsepower, and the latter figure refers to the engine speed when the maximum horsepower is output (just like the maximum speed at which a person runs at the limit speed, how long can he last at this speed).
5. Air curtain: it is also a kind of airbag, which is not equipped in ordinary cars. It is mainly used to prevent side collision and protect the safety of drivers and passengers. It mainly appears on both sides of the front seats, not the rear seats.
What does the L after 3.0L mean? The English pronoun "L" for the rise of exhaust volume is a unit.
7. Front-wheel drive and rear-wheel drive refer to whether the driving theory of the automobile is located at the front axle or the rear axle: the front wheel is used as the driving wheel and the rear wheel is used as the driving wheel when the automobile is driving. This position is the so-called front axle and rear axle, just like people use their legs (rear drive) when running. Use your arms when you do uneven bars (front wheel drive) and use your hands and feet when you climb mountains (four wheel drive).
