Automotive knowledge: how to understand the engine parameters of a car

1. Automobile engines usually have multiple cylinders, and the displacement we often say is the sum of all cylinders. It is worth mentioning that engine displacement is usually not an integer, but is obtained by rounding. For example, for a 0-liter naturally aspirated engine, the actual displacement may only be between 1980-1999 ml.

2. The engine model consists of four parts: the first part is the logo of the product series and the logo of replacement. The manufacturer selects the corresponding letters according to the needs, but it needs to be approved by the relevant departments. The middle part: It is composed of cylinder number symbol, stroke symbol, cylinder arrangement symbol, cylinder diameter symbol, etc.

3. Engine parameters refer to the technical data and construction model of the engine. For example, the number of cylinders, the cooling method, the number of valves, the cylinder diameter and stroke, the displacement, the power, the torque, the maximum power and the maximum torque, the maximum speed, the compression ratio, the basic performance, the external dimensions, etc.

Great Wall Automobile Car engine parameters

The power of the Great Wall M4 comes from a 15L naturally aspirated engine called GW4G15, which is equipped with various small cars such as dazzling C20R and Haval M2. It adopts all-aluminum material, VVT variable valve lift technology, and a maximum power of 78 kilowatts and 106 horsepower. The maximum torque is 138 Nm, and the technology and parameters belong to the mainstream level M4.

T power parameters are not bad, the maximum power is 110kW (150PS), the maximum torque is 210nm, and the peak torque burst range is 2200-4500rpm, which is relatively wide. In terms of transmission, the 6-speed manual transmission is matched with the engine, which is not bad in terms of powertrain matching.

At the parameter level, the parameters of the E20CB engine are the same on the four series of models of VVVVVVV Tank 300, with a maximum power of 167 kilowatts and a maximum torque of 387N·m.

GW4G15F is a 5T engine under Great Wall Automobile. In this engine code, "GW" is the abbreviation of the Great Wall, and "15" represents the displacement of 1500ml. At present, this engine is applied to Haval H6, Haval H7, Haval H9, Haval M6, Haval H2 and other models.

It is the power parameter of the GW4C20 turbocharged engine: the Great Wall GW4C200T engine was successfully developed in 2010 and reached the Euro V+ emission standard in that year. This engine was officially mass-produced in 2012.

Which parameter of the engine is more important for buyers to look at?

First of all, look at: power, torque, fuel consumption, and then look at several intake valves, compression ratio, power can be converted into horsepower, which is actually the same thing.

Engine displacement: The displacement of the engine is directly related to the power of the car. When choosing most family cars, cars with a displacement of 4-6 are still good for those with low requirements. A car with a displacement of 4-6 can produce 80kw-90kw power, and the fuel consumption symptoms are good.

Maximum power is one of the power parameters of the engine. Simply put, the higher the power, the higher the speed of the vehicle. Many friends will compare the maximum power of different models before buying a car, thinking that the higher the better. That's right, but there is a certain one-sidedness.

What are the parameters of the engine?

The main parameters of automobile engines are: cylinder diameter and stroke: the engine can be divided into three types according to the ratio of cylinder diameter and piston stroke, namely long-stroke engine, equal-stroke engine and short-stroke engine; total exhaust volume: total exhaust volume is also known as the total working volume of the engine, which is a The exhaust volume of the cylinder is multiplied by the number of cylinders.

Parameter, CF25 is usually 25 horsepower, is 1115, single cylinder, 115mm cylinder diameter.

Engine parameters refer to the parameters that express the basic structure of the engine, such as the number of cylinders, cylinder arrangement, cylinder diameter, piston stroke, compression ratio, engine displacement and the specified ignition order, gas distribution phase, etc. These parameters determine the basic size of the engine and are directly related to the basic performance of the engine.

The basic parameters of automobile engines include the number of engine cylinders, the arrangement of cylinders, valves, displacement, maximum output power and maximum torque. Number of cylinders The common number of cylinders in automobile engines is 8 cylinders.

What are the basic parameters of the engine?

The main parameters of automobile engines are: cylinder diameter and stroke: the engine is according to the cylinder diameter and piston strokeThe ratio can be divided into three types, namely long-stroke engine, equal-stroke engine and short-stroke engine; total exhaust volume: the total exhaust volume is also known as the total working volume of the engine, which is the exhaust volume of a cylinder multiplied by the number of cylinders.

The important parameters of the engine include engine displacement, compression ratio, power, torque and maximum speed, etc. Generally speaking, the larger the displacement, the greater the power and the better the acceleration performance. The more advanced the interior decoration of the car, the higher the grade division; while the lower the displacement, the power performance is relatively weak but more fuel-saving.

Parameter, CF25 is usually 25 horsepower, is 1115, single cylinder, 115mm cylinder diameter.
