What is the idle air flow rate of the car engine?

1. Under the condition that the idle water temperature is normal and there is no load, the standard range of the air flow meter is 2-4g/s. The idling speed of a car is generally 600-900 rings. Because the engines of different models are different, the idling value is different.Generally, the normal idling speed of the car will not exceed 1000 rfts, and it is basically about 800 rm.

2. In general, the normal value of air flow idle speed is in the range of 2.5g/s-4g/s. If the air intake system is lower than 5, the engine may have additional load. At present, under the influence of the signal parameters of the air flow sensor, there are mainly two categories: wing plate, hotline, thermal film air flow sensor and eddy current air sensor.

3. The idle water temperature is normal, no load, 2-4g/s. Generally, at 600-900 rps, and more than 1000 rps, the car may have a minor malfunction. If the speed is too high when idling, you need to go to the repair shop to find a problem. Different models have different idling values because of different engines.

engine water pump flow

1. The water flow rate is between 0.5-5 cubic meters/hour. The water flow rate of Volkswagen engine pumps does not have a fixed value, but varies according to different engine models, working conditions and temperatures. In addition, the water flow rate of the Volkswagen engine water pump can also be calculated by factors such as the speed of the water pump, the diameter of the impeller and the efficiency of the water pump.

2. The formula for calculating the flow rate of the water pump is: Q=Pη/73H. Among them, Q is the flow rate, the unit is m3/h, P is the shaft power, the unit is KW, η is the efficiency of the pump, the unit is %, 73 is the constant, H is the lift, the unit is m.

3. Flow rate: 5-300 cubic meters/hour lift: 5-250 meters rotation speed: 2900 rpm. Introduction to power cooling water pump: Introduction to multi-stage pipeline centrifugal pump (referred to as cooling water pump) I believe that friends have read the introduction of Automobile Editor and have a necessary understanding of cooling water pumps.

4. The formula for calculating the flow rate of the water pump is: Q=Pη/73H, the unit of flow: m3/h, P is the shaft power, the unit is Kw, η is the efficiency of the pump, the unit is %, 73 is the constant, and H is the lift m.

5. The calculation of water pump flow is generally based on the formula for calculating water pump flow as: Q=Pη/73H. First of all, Q is the flow rate, the unit is m3/h, P is the shaft power, the unit is KW, η is the efficiency of the pump, the unit is %, 73 is the constant, H is the lift, single Bit m.

30CC displacement water-cooled engine flow

1, ~40 liters. The flow rate of the engine water pump is generally between 10 and 40 liters/minute. For most engines, water can circulate once in the engine within 30 seconds. The water pump flow, also known as the amount of water transmitted, refers to the amount of water transported by the pump per unit time, which is intuitively displayed on the flow meter.

2. In the process of working the water-cooled engine, the engine speed will be higher. Generally speaking, if the engine used by motorcycles is 200cc, it is basically a cylinder expander, and most of them are top rods. This type of engine is improved, and the vibration generated during the work is relatively large.

3. If the displacement of the motorcycle engine is 200cc, generally speaking, the maximum power of the engine is 10-12kw, and 1kw is equivalent to 36 horsepower. Different cooling methods will also lead to differences in engine power. The air-cooled engine is limited by the cooling method, so the horsepower of the engine should not be squeezed too much.

4. If the engine displacement used by a motorcycle is 200cc, then its maximum power is generally 10-12kw, which is equivalent to 36 horsepower.The engine output of different cooling methods will also be different. The air-cooled engine is limited by the cooling method and cannot excessively thrott the engine horsepower.

5. Zongshen 300 water-cooled engine has 48 horsepower. Zongshen engine 300 water-cooled engine with an actual displacement of 301cc, with a maximum power of 35kW (48 horsepower) and a maximum torque of 34N·m, which has reached the first-class level in China. The engine has a common speed of 4000-5000. The power output is very smooth, and the daily driving experience is very good.

6. Note: Domestic motorcycles with a displacement of less than 125 are generally air-cooled, and those with a displacement of more than 125 are water-cooled. Engine displacement refers to the power size of the engine. For example, the engine of Santana cars is 8, that is, 1800cc displacement; the 125 engine of motorcycles refers to 0.125 displacement, that is, 125cc.
