Main performance indicators of the engine

1. Effective power, start The effective power output by the machine in a unit time is called the effective power, that is, the power of the engine, which is equal to the product of the effective torque and the angular velocity of the crankshaft. Engine power is the most important indicator of engine performance, and the maximum speed of a car is determined by the engine power.

2. The performance indicators of the engine mainly include: dynamic indicators, economic indicators, environmental indicators, reliability indicators and durability indicators.

3. The following is an introduction to the relevant content: performance refers toStandard: The performance indicators of the engine mainly include dynamic indicators, economic indicators, environmental indicators, reliability indicators and durability indicators.

4. 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.

5. The durability index refers to the limit time when the main parts of the engine are worn to the point where they cannot continue to work normally. It is usually measured by the overhaul mileage of the engine, that is, the mileage of the car from the engine to the first overhaul.

6. The performance of the engine mainly includes dynamic and economic indicators.The dynamic indicators of the engine are often expressed by the torque and power emitted by the engine.

What are the performances of the engine?

1. The working performance of the engine includes the following: Effective torque: refers to the torque output by the engine through the crankshaft or flywheel.Effective power: refers to the power output by the engine through the crankshaft or flywheel. Crankshaft speed: refers to the number of rotations per minute of the engine crankshaft, usually expressed in n, and the unit is r/min.

2. 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.

3. There are two main indicators for the performance of the engine, one is power and the other is torque. The unit of power is kilowatt or horsepower, and the unit of torque is N/meter. Generally speaking, power reflects the absolute speed of the car, or how fast it can run; torque reflects acceleration, that is, the speed-up energy.

4. Effective power, the effective power output by the engine in a unit time is called effective power, that is, the power of the engine, which is equal to the product of the effective torque and the angular velocity of the crankshaft. Engine power is the most important indicator of engine performance, and the maximum speed of a car is determined by the engine power.

5. Secondly, fuel economy is another important indicator. Fuel economy refers to the mileage that the engine can travel in a unit of time, which is an important criterion for measuring the cost of car use. Generally speaking, the better the fuel economy of the engine, the lower the cost of use.

What are the reasons that affect the engine performance

rust and scaling of the water tank are the most commonThe problem is that rust and scale will limit the flow of antifreeze in the cooling system, reduce the heat dissipation effect, causing the engine to overheat, and even cause engine damage. It is best to use water tank cleaning agent regularly to extend the overall life of the water tank and engine.

The influence of the transmission ratio of the main reducer. The choice of the transmission ratio of the main reducer mainly considers the purpose of the car and the frequently used road conditions. The influence of the transmission system gear number. When there is no secondary transmission and divider, the number of transmission system gears is the number of gears of the forward gear of the transmission.

Engine performance: The performance of the engine (such as maximum power, maximum torque, rotation speed, etc.) and reliability are one of the most important factors affecting the dynamics of the vehicle. Transmission system: The transmission system includes transmissions, clutches and gears of different gears, and the degree of matching with the engine has a great impact on the dynamics of the vehicle.

The specific analysis is as follows; sensor problem; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, and at this time it will Cause the engine fault light to turn on.

Cause and treatment method; Too much carbon accumulation in the engine: Too much carbon accumulation in the valve and intake pipe is the most common reason for engine power degradation. Solution: Find a professional auto repair staff to help clean up the accumulated carbon and check whether the spark plug needs to be replaced.
