1. The higher the maximum speed, the greater the engine power required, and the engine power should be greater than or equal to the sum of the driving resistance at the maximum speed. In actual design, statistical methods are usually used to estimate the specific power of the car to determine the power of the engine. The specific power refers to the engine power per unit of the total mass of the car, and the unit is kw/t.
2. 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 number of cylinders commonly used in automobile engines is 8 cylinders.
3. The higher the effective thermal efficiency, the better the economy of the engine. At present, the thermal efficiency of the engine is between 30% and 40%, and the thermal efficiency of diesel engines is generally higher than that of gasoline engines. Now the thermal efficiency of the engine has reached a bottleneck, and it is difficult to improve it again.
4. The basic parameters of the automobile engine include the number of engine cylinders, the arrangement of the cylinder, the valve, the displacement, the maximum output power and the maximum torque. Number of cylinders The common number of cylinders in automobile engines is 8 cylinders.
5. The higher the compression ratio, the better the combustion and work of the engine, and the greater the possibility of combustion and explosion, so high-standard gasoline needs to be used. The higher the compression ratio, the greater the power of the engine. Nowadays, the compression ratio of mainstream self-aspiration engines is close to 10:1, but some brands can reach a compression ratio of 13:1.
1. The editor believes that ordinary families buy a car, buying a low-power version will be more Well, it is cost-effective and economical for future use. If you are a person who pursues speed and driving pleasure, high power is indeed a good choice.
2. The advantages of a high-power engine are strong power and high driving pleasure. The disadvantages are high fuel consumption, high maintenance cost, and high price of models equipped with high-power engines. The advantages of small-power engines are low fuel consumption, low maintenance costs and low price. The disadvantages are that the driver may feel insufficient power in some cases.
3. The repair and maintenance cost is high, and the price of models equipped with high-power engines is also higher. The advantages of low-power engines are low fuel consumption, low repair and maintenance costs, and low price. The disadvantages are that drivers may feel insufficient power under certain circumstances.
1. The displacement of the engine theoretically directly determines the power performance of the vehicle, so according to common sense, the larger the better, but in actual use, the larger the displacement, the better.
2. No. Displacement is a special term for hydraulic transmission, which specifically refers to the volume of fluid inhaled or discharged in each stroke and each cycle. Theoretically, the larger the engine displacement, the greater the power and torque, but it also depends on the manufacturer's adjustment of the engine.
3. This is the case in theory. The larger the engine displacement, the greater the power and torque, but it also depends on the manufacturer's adjustment of the engine. For example, in some high-performance sports cars, it needs a high-power engine, which means it can run very fast, so car manufacturers will adjust the power of the engine and the torque will be lost.
Displacement refers to the displacement of the engine. The advantages of large displacement are high horsepower, high speed, large torque and fast acceleration. The disadvantage is that, in general, the larger the displacement, the higher the fuel consumption, and the high cost of self-maintenance. The classification of cars in China is determined by the size of the displacement.
The larger the internal volume of the engine, the more cylinders the engine has, indicating that the actual displacement of the engine will be larger and the power performance that can be released is also more sufficient. But correspondingly, its fuel consumption will also be relatively high, and the later maintenance cost will also be relatively high.
Generally speaking, the larger the displacement, the larger the car, and the larger the energy released by the engine per unit time, that is, the "power" is good. For example, a good off-road vehicle should be at least V8 or 4L.
1. In cars, the suitability of the engine and the whole vehicle also has a great impact on the fuel consumption of the car. There are practical examples that show that if a small-displacement engineIf the adaptability is poor, it is likely that it will not be more fuel-efficient than large-displacement engines, and even more fuel-efficient than large-displacement engines.
2. Compared with similar engine cars, the larger the torque output, the greater the carrying capacity, the better the acceleration, the stronger the climbing ability, the fewer the number of gear changes, and the wear of the car will be reduced accordingly.
3. In cars, the adaptability of the engine and the whole vehicle has a great impact on the economy of the car. If the adaptability of a small-displacement engine is not good, it is likely to be more fuel-efficient than a large-displacement engine, and even more fuel-efficient than a large-displacement engine.
