Language
People often compare the engine of a car to the heart of an adult. It can be seen from this that the engine is the most indispensable part of the car, so the daily maintenance of the car engine is very important
Car engines are often compared to the heart of an adult
It can be seen how important it is to the car
Engine is a machine that converts other forms of energy into mechanical energy
For example, a gasoline engine converts chemical energy into mechanical energy.
This is like eating a few steamed buns and having the strength to work
But the same is to eat steamed bread, gasoline engines are also divided into many categories, just like people are tall, short, fat and thin.
By piston movement
The engine is divided into two types: reciprocating piston type and rotary piston type
Among them, the reciprocating piston engine has high efficiency, small size, light weight and high power, and is widely used as vehicle power.
Rotary piston engine also known as rotary engine
It has high power, low vibration, stable operation, simple and light structure
But it is generally only suitable for high speed
and poor fuel economy and low speed performance
Therefore, it has not been widely used
According to the arrangement of cylinders, it is divided into:
Inline engine
Compact size, high stability, good low-speed torque characteristics, low fuel consumption, low manufacturing cost
Horizontally opposed engine
The center of gravity is low, the vehicle is more stable, but the cost is high
V-engine
Small height and length for easy layout
It can also offset the vibration during operation, making it more stable
W type engine
Save the space occupied by the engine and light weight
The most widely used in-line engine
By air intake
Engines can be divided into
Naturally aspirated and supercharged engines
Naturally aspirated engine
means that the air passes through
Air Filter → Throttle Valve → Intake Manifold
Reach the cylinder
A supercharged engine is one that will enter the engine cylinders
Air or combustible gas mixture is compressed and then cooled to increase density
In order to improve the engine power, improve the specific power
Improve fuel economy and more
simply put
Naturally aspirated engine allows people to breathe freely
The supercharged engine is artificial respiration
Both engines are widely used
But like artificial respiration, although it's cool
But usually never
Therefore, although there is a lot of publicity for supercharged engines
The ones that sell a lot are still models with naturally aspirated engines
More than 100 years after the invention of the automobile
It is because of the continuous innovation of technology stable and rapid development
Advances in engine technology
The growth of the human mind
It is a sign of a more mature product
