Do you prefer a turbocharged engine or a naturally aspirated engine in a sports car?

Abstract: Turbocharged engines and naturally aspirated engines have advantages and disadvantages. The most intuitive point is that the turbocharged engine has a lot of power, but the fuel consumption is also large. Naturally aspirated engines are easier to maintain, but do not burn enough gasoline. In a sports car, I think a turbocharged engine is more suitable. Turbocharged engines, which rely on pounding to achieve more power, are better suited for racing. This article will go into detail about turbocharged engines and the reasons for preferring them.

The earliest turbocharged engines were used in sports cars or formula cars, so in some motor racing competitions with limited engine displacement, the engine could get more power. As we all know, the engine is output power by burning fuel in the cylinder to do work, because the amount of fuel input is limited by the amount of air drawn into the cylinder, so the output power of the engine will also be limited. If the engine is operating at its best, and then the output can only be increased by compressing more empty air into the cylinder to add fuel, then the combustion power will be improved. Therefore, under the existing technical conditions, the turbocharged engine is the only mechanical device that can increase the output power of the engine without changing the working efficiency.


A turbocharged engine is an air body compressor that compresses the air body to increase the intake. It uses the inertial impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine room, and the turbine drives the coaxial impeller to press the air body sent by the air body filter tube into the cylinder.


As engine speed increases, exhaust speed and turbine speed increase simultaneously, and the impeller compresses more air into the cylinder. The pressure and density of the air body increase, more fuel is burned, and the output power of the engine can be increased by increasing the amount of fuel and adjusting the engine speed accordingly.


Turbocharged engines are typically smaller and lighter than naturally aspirated engines of the same power class, which means they can improve a car's weight distribution and handling. Turbocharged engines also have higher fuel efficiency and lower emissions than naturally aspirated engines because they can use less fuel for the same amount of power.


A naturally aspirated engine is an engine that does not use any forced air intake to increase the intake of air and fuel. Naturally, aspirated engines rely on atmospheric pressure and engine speed to fill the combustion chamber with air and fuel. Naturally, aspirated engines are simpler and more reliable than turbocharged engines because they have fewer parts and systems that can fail or malfunction. Naturally, aspirated engines also have better throttle response and sound quality than turbocharged engines because they don't suffer from turbo lag or excessive noise.


At present, turbocharged engines continue to develop along the path of miniaturization. At the same time, the matching inlet and exhaust and other related technologies continue to progress and change. The biggest driving force for the widespread application of supercharging technology comes from strict fuel consumption regulations. Gasoline engines based on turbocharging technology have occupied the market in an all-around way. Increased fuel efficiency, improved response speed, and reduced pump and mechanical losses are the advantages of turbocharged engines.

If you want to ensure that the power of your diesel car can be sufficiently demonstrated, you can start the diesel car after the turbocharger starts to run, idle it for 3 to 5 minutes, and then slowly accelerate, do not rush the fuel door, until the oil temperature rises and the turbocharger is fully lubricated, and then increase the speed with load operation.


It is also necessary to avoid long-term idle operation, which will increase fuel consumption, poor lubrication due to low lubricating oil pressure, too long idle time, the positive pressure on the exhaust side is too low, the pressure on both sides of the turbine end seal ring is unbalanced, the oil will leak into the turbine shell, and sometimes there will be a small amount of burning oil, so the idle operation time should not be too long.


Avoid sudden shutdown in the case of high temperature and high-speed operation, so as not to interrupt the lubricating oil, causing the supercharger shaft and shaft sleeve to bite.


Summary:When the engine is equipped with a turbocharger, the maximum power can be increased by 40% or even higher than without a turbocharger, which means that the same engine can output more power after a turbocharged engine. In sports cars, we need to consider not only the problem of power and efficiency but also other issues such as emissions and torque, which I will introduce to you later, if you have questions about turbocharged engines, you can contact us, and we can provide you with professional knowledge and provide you with quality assurance products.
