The second floor really dares to say that fuel consumption horsepower. Is that how it counts? For example, the engine.
At idle (e.g. waiting for a red light), its fuel consumption is comparable to that of a displacement naturally aspirated engine. When the engine accelerates sharply and exerts its power performance, its fuel consumption reaches the fuel consumption of the engine. And even more.
Therefore, turbocharged engines should be fuel-efficient, and fuel savings can only be found when frequent traffic jams are often idling. But don't sacrifice engine life for the sake of fuel savings. For example, in order to achieve the same power performance, the engine speed will be higher.
Naturally-aspirated engines, on the other hand, require relatively low revs to achieve the same level of power. The speed of the engine is not only reflected in the degree of tranquility, but also directly affects the degree of wear and tear of the engine. The long-term high speed of the engine will inevitably make the cylinder wear more serious.
Under the premise of the same manufacturing process, the life of a low-displacement turbine engine is necessarily lower than that of a naturally aspirated machine. Why street car racers generally prefer turbocharging, because this type of car needs power over life. For the sake of motivation, anything can be discarded.

The fuel economy of the turbo engine is compared with the relative displacement size, or the fuel consumption is determined by the driving habits, vehicle conditions, and road conditions.
-
It is not necessarily fuel-efficient, and the larger the displacement of the turbocharged engine, the more fuel-intensive it is in the same situation.
-
The turbocharged engine is actually the same as the self-priming model, and the large displacement must be the same fuel consumption, right, but the model is relatively economical and fuel-efficient.

Whether the turbocharger can save fuel or not is a situation.
Before the turbine is positively pressurized, the engine is still running in a naturally aspirated state, and the oil consumption is basically the same as that of a naturally aspirated engine of the same displacement.
The turbocharged intake pressure is larger, the inlet is larger, and the fuel injection volume is also up. Compared with naturally aspirated air with the same displacement, fuel consumption will naturally be larger.
Generally speaking, there is no significant difference in fuel consumption between the turbocharged models with a smaller displacement and the naturally aspirated models with a slightly larger displacement.
In contrast, turbo vehicles may have a significant fuel consumption advantage when driving at high speeds, but they have no advantage when driving in congested urban conditions. Due to the congested road conditions in urban areas, the turbine will work more frequently. As a result, the efficiency of the engine will be reduced, and the speed of the turbine will put pressure on the engine.
Turbines were originally used in aircraft engines. It wasn't until 1961 that General Motors tentatively installed turbochargers on one of its models. In the seventies of the twentieth century, the Porsche 911 with a turbocharger was born.
In the 80s of the last century, it was used by truck manufacturers to use it in their respective truck engines. In the 21st century, turbines can be said to really start to enter the trend.
So, what is the main role of a turbine? A turbine is actually an air compressor that compresses air to increase the air intake of the engine. Generally speaking, turbocharging uses the inertial impulse of exhaust gases discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which compresses and transports the air from the air filter duct to pressurize it and enter the cylinder.
When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, the pressure and density of the air increase can make more fuel fully combusted, increase the amount of fuel and adjust the speed of the engine, you can increase the output power of the engine.

Cars with turbocharged engines are comparatively more fuel-efficient.
Turbocharged engines work by forcing more air and fuel mixtures into the cylinders for compression in the same unit of time, producing more power at the same rpm and improving the fuel economy of the car.
Turbocharging mainly uses the exhaust gases generated by the engine to drive the compressor to work, and can also pressurize the intake air. The whole booster process will not consume the power of the engine, and the acceleration continuity is good. It should be noted that the turbo does not intervene when the car is driving at low speeds, and the turbine has a certain lag.
Turbocharged engines are more thermally efficient than naturally aspirated engines. If the power output of the naturally aspirated engine and the turbocharged engine is the same, that is, the effective power output of the engine per unit time is the same, if the engine consumes less fuel at the same power, it means that the thermal efficiency of the engine is higher.
With the same power, the basic displacement of a turbocharged engine should be smaller, an engine with a smaller displacement will produce a larger load, and the engine will be more efficient when the load is larger.
Many people have the impression that Nissan's biggest advantage is that fuel consumption is relatively low. The reason why it is fuel-efficient, many people attribute it to one reason: Japanese cars. >>>More
It's hard to say, but Foss.
The last time I changed the oil oil, the staff said that the oil was not viscous enough, and the oil was not transparent, I didn't believe it at the time, but after driving more than 2,000 kilometers, the sound of engine idling and the sound of refueling was very hoarse. Then this time I changed the imported GT engine oil, and after running 10,000 kilometers, there was no engine noise and shaking, so it is really hard to say whether the FOSS engine oil is real or not, and I dare not buy it again. >>>More
No, it's just about speed.
When buying a car, many people think that small displacement is good, especially family cars, which are convenient to travel, so they generally choose small displacement. Because large displacement is more fuel-intensive, many people will choose small displacement, but there is a saying that high-speed driving with large displacement is more fuel-efficient, is this true? >>>More
The moon landing was true At that time, the US lunar landing program was mainly against the Soviet Union, and after Gagarin's first space circumnavigation, the United States ** accelerated the moon landing program to compete with the Soviet Union in space military But in general, due to the immaturity of technology and the fact that the Soviet Union was not capable of landing on the moon for the time being, after the first moon landing was successful, the United States ** did not immediately make preparations for the second time.
The fuel consumption is very low, very comfortable, the power is good, the quality is very stable, and the tire noise is acceptable. >>>More
