What is engine cylinder block

cylinder head Generally known as the cylinder head, it is a part of the engine, the engine cylinder head. The cylinder head is installed on the cylinder block, sealing the cylinder from the upper part and forming a combustion chamber. It is often in contact with high-temperature and high-pressure gas, so it bears a large heat load and mechanical load.

The cylinder block of a car engine can be said to be the brain of a person who is a car engine and has the function of temperature control. But when asked about the raw materials of the cylinder block of the car engine, many friends have not grasped it to this extent. Today, let's give you a score.

The engine cylinder block is made of integral cast steel or cast aluminum, and then machined. It is a part itself, and it is not composed of any parts.

The cylinder block of the engine is commonly used in cast iron and aluminum alloy. The engine consists of two major parts, the cylinder block and the cylinder head, which are connected to each other by bolts. Alloy cast iron is commonly used as engine cylinder block materials, but cast iron has many innate shortcomings, such as heavy weight, poor heat dissipation, high friction coefficient, etc.

Engine overhaul. Overhaul is to replace aging accessories on the basis of the original engine, such as cylinder liner, boring cylinder, grinding crankshaft, replacing piston, piston ring, replacing valve grinding valve, etc.

The cylinder block is the heaviest part of the engine, so the use of aluminum alloy material can reduce the weight of the engine, so as to achieve the purpose of reducing the weight of the whole vehicle.

Accord engine cylinder block materials

1. According to the official introduction of GAC Honda, all Accord engines use aluminum cylinder blocks. Compared with cast iron cylinder blocks, aluminum cylinder blocks have better heat dissipation effect and smaller engine weight, which can reduce the fuel consumption of the car to a certain extent. As of November 2019, most of the cars on the market have aluminum cylinder engines.

2. The cylinder block material of the engine should have sufficient strength, good casting and cutting, and the price should be low. Therefore, the commonly used cylinder block material is cast iron alloy cast iron, but the cylinder block of aluminum alloy is more and more common, because the aluminum alloy cylinder block is light in weight, has good thermal conductivity, and the capacity of coolant can reduce the opening After moving, the cylinder block will work quickly.

3. The cylinder head and cylinder block materials of GAC Honda Accord are all made of aluminum alloy.

Is the engine cylinder block better, iron or aluminum?

1. The cylinder block of aluminum alloy is good. At present, the cylinder blocks of gasoline engines are divided into cast iron and cast aluminum.In diesel engines, cast iron cylinder blocks account for the vast majority. In recent years, with the rapid development of the automobile industry, cars have rapidly entered the lives of ordinary people. At the same time, the fuel-saving performance of vehicles has gradually been paid attention to.

2. Each has its own advantages. The cast iron cylinder block can withstand relatively large pressure; aluminum alloy is light in weight and has good heat dissipation. At present, the cylinder blocks of gasoline engines are divided into cast iron and cast aluminum. Compared with cast iron engines with the same displacement, all-aluminum engines will be about 20 kilograms lighter in weight. And the most direct benefit of weight reduction is to save fuel.

3. The physical properties of iron and aluminum are different. The heat load capacity of the cylinder block of cast iron is stronger, and the potential of cast iron is greater in terms of engine power increase. It is not only conducive to the start and acceleration of the vehicle, but also can shift gears early to achieve the effect of fuel-saving.

Is the engine cylinder block made of aluminum or iron better?

However, the wear resistance of aluminum alloy cylinder blocks is not enough, and cylinder liners need to be installed to improve the service life of the engine. The cost of aluminum alloy cylinder blocks is also higher than that of cast iron. The biggest advantage of cast iron materials is that the price is cheap, which can reduce the cost of the engine. The cast iron cylinder blocks are also resistant to high pressure and high temperatures. The advantages of not easy to deform.

The cylinder block of aluminum alloy is lighter in quality and better in heat dissipation. The biggest benefit is that the operation is relatively flexible. Theoretically, the quality of aluminum alloy will bring lower fuel consumption. But the only advantage of the cast iron cylinder is that it is stronger.

Car engine cylinder block materials cast iron and aluminum alloy have their own advantages. The engine material has little impact on the performance of the car. Which material engine to choose does not have a big impact on the daily use of the car.Advantages of cast aluminum cylinder block: In terms of use, the advantage of cast aluminum cylinder block is that it is light in weight and saves fuel by reducing weight.

At present, there are two main types of cylinder block materials for automobile engines: cast iron and aluminum alloy. Many people are arguing about which material is better. In fact, it is impossible to say which material is better. It should have its own advantages and disadvantages.

In addition, iron is the standard material because of its durability. Iron engine cylinder blocks are stronger and more durable than aluminum cylinder blocks. Compared with aluminum cylinder blocks, iron cylinder blocks can withstand higher pressure. Another advantage of iron cylinder blocks is power. Due to its great strength, the iron cylinder block can provide greater power output.

Iron engineAdvantages and disadvantages of engine cylinder block and aluminum engine cylinder block

Reduce the weight of the engine and save fuel. The use of cast aluminum cylinder block can reduce the weight of the engine. In terms of use, the advantage of cast aluminum cylinder block is that it is light in weight and can save fuel by reducing weight. In an engine with the same displacement, the use of an aluminum cylinder engine can reduce the weight of about 20 kilograms.

The difference between engine cylinder block iron and aluminum is as follows: cast iron cylinder: its wear resistance and durability are better than that of aluminum cylinder, and its cost is also relatively low.

Disadvantages: Aluminum engine cylinder blocks are more likely to deform, especially under pressure. This is because they are not as hard as cast iron. In addition, aluminum blocks are expensive, which makes their production cost very high, thus raising the price of cars. A more important aspect that needs to be considered is that the aluminum engine cylinder block generates less power.

Advantages: The all-aluminum engine is light in weight and saves fuel by reducing weight. In an engine with the same displacement, the use of an aluminum cylinder engine can reduce the weight of about 20 kilograms. For every 10% reduction in the weight of the whole car, the fuel consumption can be reduced by 6% to 8%.
