Suction What is the difference between gas and turbocharging?

The difference between natural intake and turbocharging: under the same displacement, turbocharging is more powerful than self-suction. The maintenance cost of turbocharger is higher than that of self-priming.Under the same displacement, the turbocharged engine is more fuel-saving in high-speed working conditions. The manufacturing cost of turbocharged engines is higher than that of self-aspiration engines.

The differences between natural intake and turbocharging are as follows: under the same displacement, turbocharging is stronger than self-suction. The maintenance cost of turbocharged is higher than that of self-suction. Under the same displacement, turbocharged engines are more fuel-efficient under high-speed working conditions. The manufacturing cost of turbocharged engines is higher than that of self-aspiration engines.

The control performance is different. The engine power output of the naturally aspirated mode is easier to control, the acceleration is smooth, the acceleration is also very uniform, and the fine throttle control point is easy to find; while the power output of the turbocharged engine is not as good as the naturally aspirated engine.

Power: Under the condition of the same displacement,The power of turbocharged engines is more explosive than that of naturally aspirated engines. When choosing an engine, if the owner likes flexible power output, he should choose a naturally aspirated engine. If he likes sufficient power, he can choose a turbocharged engine.

What is the engine of Toyota Asia Dragon

1. The Asian Dragon engine is an imported Asian Dragon engine and gearbox made in Japan. The assembly quality is no problem when transported to Changshu, China. The Asian Dragon engine adopts an A25A 25L self-aspirated engine, with a maximum output power of 154kW and a maximum torque of 250Nm. The chassis adopts a front McPherson rear multi-link type. The suspension structure of the Asian Dragon is Toyota.

2. Asia Dragon is equipped with two engines, one is a 0-liter naturally aspirated engine and the other is a 5-liter naturally aspirated engine. There is also a hybrid version of this car, equipped with a 5-liter naturally aspirated engine and a 120-horsepower electric motor.

3. Asia Dragon is equipped with a total of two engines, one is a 0-liter naturally aspirated engine and the other is a 5-liter naturally aspirated engine. This car also has a hybrid version, which is equipped with a 5-liter naturally aspirated engine and a 120-horsepower electric motor.

4. Toyota Asia Dragon is equipped with 0L and 5L engines, with actual displacements of 1987ml and 2487ml respectively. 0L version engine: 0L version engine has a total of 4 cylinders, the arrangement form is L, and the intake method is naturally aspirated.

Is the car engine self-aspirated or turbocharged better

The acceleration performance of the turbocharged engine is better. This is because the turbine engine has a larger "lung capacity". We all know that people with large lung capacity are of course more energetic when exercising.

The turbocharged engine accelerates better. This is because the lung capacity of the turbine engine is larger, and people with large lung capacity are of course more energetic when exercising. General turbineThe power of the supercharged engine can reach the level of a naturally aspirated engine equivalent to about 3 to 5 times its displacement. But this is just an average degree.

The advantages of naturally aspirated are not available in turbocharging, and the advantages of turbocharging are also incomparable for people who drive naturally aspirated cars. It mainly depends on what type of engine the driver likes.

Compared with automobile turbocharging and natural aspiration, turbocharging is better. The specific reason is that under the same displacement, the power of vortex energy supercharging is obviously stronger than that of natural intake, and everyone has no objection to this.

How to solve the loud engine intake sound

1. Solution: Same as above, check the plastic parts in the engine compartment, and generally tighten or adjust them.

2. Change the oil. It is necessary to maintain the car regularly and on time. Even if the mileage is not reached, the old oil should be released, because the oil will be oxidized. After a long time, its various indicators will decrease, which will not achieve the proper protection for the engine and produce noise. Therefore, the oil should be replaced in time. Clean up the throttlum valve.

3. Install sound-absorbing foam material on the engine cover; replace the intake and exhaust pipe; add a vibration damping plate to match the sound-absorbing pad; install or replace the door seal. The reasons for the louder noise of the car engine are: excessive carbon accumulation in the engine, aging of the foot rubber pad, improper use of oil, abnormal operation of the engine cylinder and engine explosion.

Aspirated engine: naturally aspiratedEngine

Of course, aspirated engines (generating propusion by compressing air and burning mixed fuel) are nothing new.

The naturally aspirated type has no supercharger, which means that the air simply passes through the air filter, throttle valve (commonly known as "throttle") and intake manifold to reach the cylinder, and gasoline is directly injected into the intake manifold through the fuel injector.

The naturally aspirated engine has existed for a long time, and the technology is reliable and the quality is stable.
