2. Effective torque, the torque output by the engine is called the effective torque, that is, the torque of the engine.Generally, the greater the torque of the engine, the stronger its acceleration and climbing ability. Generally, the larger the cylinder diameter of the engine, the longer the piston stroke, and the greater the torque of the engine. This is also one of the reasons why large-displacement engines have greater torque.

3. The performance index of the engine is used to characterize the performance characteristics of the engine and serve as a basis for evaluating the performance of various engines. Generally, there are dynamic indicators, economic indicators, strengthening indicators, compactness indicators, environmental indicators, reliability indicators, durability indicators, technological indicators, internal combustion engine speed characteristics, etc. Let's talk about it separately.

4. The three performance indicators of the engine include dynamic indicators, economic indicators and environmental indicators. Dynamic indicators refer to the size of the engine's functional force, economic indicators refer to the expression of the effective fuel consumption rate, and environmental indicators are the exhaust quality of the engine.

5. The main indicators of engine performance are: speed, power, torque, fuel consumption rate, etc. These indicators are usually marked in the instructions of the car or engine. In addition, there are some relative indicators, such as power increase, torque increase, mass increase, mass ratio, etc., which can be compared between different engines.

6. The performance indicators of the engine mainly include: power indicators, economic indicators, environmental indicators, reliability indicators and durability indicators. The performance index of the engine shows that the power index is an indicator that characterizes the working ability of the engine.

The current price is relatively affordable, but the configuration is as good as before, so I think Mercedes-Benz's performance ratio is stronger.

First place: Honda. The engine failure rate of imported Honda cars is 0.29%, which can be said to be very high. The most famous masterpieces of the engine of Japanese Honda cars are the VTEC system and the i-VTEC system, which have high performance.

BMW's N54 is Europe's 2JZ, a famous generation. The origin of the N54. At the beginning, BMW's engine performance was not outstanding (it was still excellent on civil engines), but there is a saying that it did not progress or retreated. Yes, at that time, Japanese car brands Lexus and Nissan worked hard to develop 2GRFSE series and VQ series engines.

v engine is a high-performance engine, which is characterized by a larger number of valves, smoother intake and exhaust, and can provide greater power output. Therefore, many car brands have adopted 16v engines. Let's take a look at which brands of 16v engines are better.

Engine performance index-dynamic index

Generally, the effective torque, power, speed and average effective pressure of the engine are used as indicators to evaluate engine performance. Effective torque: The torque output by the engine is called the effective torque, which is written as Te, and the unit is Nm. The product of the effective torque and the crankshaft angular displacement is the effective force of the engine output.

The main indicators of engine performance are: speed, power, torque, fuel consumption rate, etc. These indicators are usually marked in the instructions of the car or engine. In addition, there are some relative indicators, such as power increase, torque increase, mass increase, mass ratio, etc., which can be compared between different engines.

The three performance indicators of the engine include the dynamic indexStandard, economic indicators and environmental indicators, dynamic indicators refer to the size of the functional force of the engine, economic indicators refer to the expression of the effective fuel consumption rate, and environmental indicators are the exhaust quality of the engine.
