I find that when many friends go to buy a car, when engine is mentioned, seller will brag about it. Whether it's a cast iron engine or an all aluminum engine, many friends are easy to fool because they don't understand it! Today, editor will acquaint you when buying a car with what is better to choose: a cast-iron engine or an all-aluminum engine!
The engine is most important part of car, it can be said that it is core of car, so many people will carefully consider which car engine is better when buying a car, because a good engine can keep car running for several more years. Now there are two common engines ,one is an all aluminum engine and other is a cast iron engine. Many people will struggle when buying a car. Is it better to use an all aluminum engine or cast iron is better? Today, editor will tell you about the advantages and disadvantages of all-aluminum engines and cast iron engines, as well as which one is more suitable for home use.
Let's analyze difference between them first!
First look at cast iron engine. As name suggests, a cast iron engine is made from iron. It is definitely better than an all-aluminum engine in terms of strength, because engine must have good heat and high pressure resistance, and a cast iron engine has these two points. ! Thanks to superior materials, engine can easily unleash its full power! But disadvantages of cast iron engines are also very noticeable, i.e. they are too heavy!
A cast iron engine is complete opposite of an all aluminum engine. The strength of iron is higher than that of aluminum, so cast iron motor will be especially resistant to high temperature and high pressure, so power will be relatively large, and cast iron motor is not subject to corrosion and deformation. The advantages of cast iron motors are deformation resistance, high pressure and high temperature resistance, strong corrosion resistance, and relatively low cost.
Then open aluminum engine! Because weight of cast iron engine is too large, weight of aluminum engine is very light, aluminum engine can dissipate heat more easily, and fuel consumption is much better than cast iron engine, but there are disadvantages. many disadvantages of aluminum engine, such as hardness and strength than cast iron engine, and it is bigger, it costs more, and it is more expensive!
The advantages of an all-aluminum engine are light weight, easy processing, good heat dissipation and low fuel consumption. We all know that aluminum is much lighter than iron, and engine is not a small thing, so all-aluminum engine is much lighter than cast iron. The lighter engine, lighter weight of car itself, and weight of car will affect fuel consumption, so all-aluminum engine is more economical. than cast iron. Many people are now concerned about fuel consumption, so if you want to save fuel, an all-aluminum engine is a good choice. In addition, heat dissipation effect of aluminum will be better, especially during operation of motor, temperature rise is especially strong, so all-aluminum motor will dissipate heat better than cast iron motor, and less likely to explode.
The disadvantages of an all-aluminum engine are large volume, poor corrosion resistance, low strength, and a high coefficient of friction. Since strength of aluminum is less than that of iron, if an all-aluminum engine wants to achieve strength of a cast iron engine, it needs more aluminum, so volume will be larger, and it will not be as compact as a cast iron engine. In addition, aluminum is extremely corrosive at high temperatures, so an all-aluminum engine will be more prone to corrosion and less durable, and an all-aluminum engine will be more easily deformed due to its low strength, and aluminum content is relatively high, so an all-aluminum engine will be a little more expensive.
Models with all aluminum motors tend to have a higher price because all aluminum motors are more complex than cast iron motors and subsequent maintenance costs are also higher, and cast iron motors are cheaper and subsequent maintenance costs are also below!
So, if you are an experienced driver who loves to study cars, then editorial staff still recommends that you buy a cast-iron engine that is resistant to toss! If you're buying a car for home use only, then an all-aluminum one is your best bet, and it's more economical than a cast iron engine!
