The reason there are holes in the engine hood is for heat dissipation. Some are due to high compression ratio boosting. You can open the engine hood to check what's underneath—if it's an intake partition, then it's for boosting; if it's an intercooler, then it's for heat dissipation. Airflow Guidance Function: For objects moving at high speed in the air, the air resistance and turbulence generated around the moving object directly affect its trajectory and speed. The shape of the engine hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the force of the front tires on the ground, which helps stabilize the car's movement. Protection for the Engine and Surrounding Pipeline Components: Under the engine hood are critical components of the car, including the engine, electrical circuits, oil circuits, braking system, and transmission system. These are vital to the vehicle. By enhancing the strength and structure of the engine hood, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle.

How to Check Emission Standards?

Emission standards can be checked by logging into the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center. For new vehicles, the standards can also be found in the vehicle's factory certificate, though typically this certificate is kept by the vehicle management office. Vehicle emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC (hydrocarbons), NOx (nitrogen oxides), and PM (particulates, soot). The emission standards for vehicles include National I, National II, National III, National IV, National V, and National VI standards. Up until December 31, 2018, the National V emission standard was in use, and currently, the country implements the National VI emission standard.

How many kilometers can a 4.11 gear ratio run at 1500 RPM per hour?

With a 4.11 gear ratio at 1500 RPM, the vehicle can travel 95 kilometers per hour. The gear ratio refers to the transmission ratio of the gears in the car's drive axle's main reducer. It is equal to the ratio of the rotational angular velocity of the drive shaft to that of the axle's half-shaft, and also equals the ratio of their rotational speeds. When using a mechanical reducer, the ratio of the motor's rated speed (nN) to the output shaft's speed (nL) is called the gear ratio I (also known as the transmission ratio). If the motor employs other speed control methods, such as variable frequency speed control or slip speed control, the ratio of the motor's maximum speed to its minimum speed is called the gear ratio, indicating the range of speed adjustment.

Which gear to use for automatic transmission on highways?

For automatic transmission on highways, you can simply use the D (Drive) gear. If you want to overtake, you can temporarily switch to the S (Sport) gear. The D gear is the forward drive gear, and when the gear lever is set to D, the vehicle will automatically shift gears based on throttle opening and speed data. The S gear is the car's sport mode; when the gear lever is set to S, the transmission can shift freely, but the shift timing is delayed, allowing the car to operate at high speeds in lower gears for an extended period, thereby achieving greater torque output and acceleration. Automatic transmission means there is no need to manually shift gears while driving, with its advantage over manual transmission being easier driving. Additionally, automatic transmission includes continuously variable transmission (CVT), electronic paddle shifters, and electronic gear levers. There are three types of transmissions available in the market: manual transmission, automatic transmission, and semi-automatic transmission.

What is the conversion between horsepower and kilowatts?

Horsepower and kilowatt conversion is: 1 metric horsepower equals 0.7354988 kilowatts. Horsepower is a unit of power, where 1 horsepower equals the work done to lift a 75-kilogram object 1 meter per second. Kilowatt is a unit of power, equal to 1000 watts. Kilowatts were initially mainly used in electrical applications, but now have a trend towards broader applications. In electrical terms, kilowatt-hours are completely equivalent to 'degrees', just with different names. Both horsepower and kilowatts represent the work done by an engine. An engine is a machine capable of converting other forms of energy into mechanical energy, first developed in the UK. It can refer to either the power generation device or the entire machine including the power unit.

How to Clean the Three-Way Catalytic Converter?

The cleaning method for the three-way catalytic converter is the drip-feed cleaning method. This method involves connecting a plastic hose to the engine's vacuum solenoid valve and using the air pressure in the hollow tube to draw the cleaning agent from the infusion bottle into the engine. As the cleaning agent is expelled through the exhaust pipe, it cleans the three-way catalytic converter. The three-way catalytic converter generally consists of four parts: the shell, the vibration damping layer, the substrate, and the catalyst coating. Below are the detailed descriptions: Shell: Made of stainless steel to prevent the shedding of oxide scales, which could clog the substrate. Vibration damping layer: Composed of gaskets or wire mesh pads, it serves to seal, insulate, and secure the substrate. To protect the substrate from damage caused by vibration, thermal deformation, and other factors, the gasket is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. Substrate: Made of honeycomb-shaped ceramic material, though many are also made of metal (including stainless steel). Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent.

What does Toyota's 10-speed CVT transmission mean?

Toyota's 10-speed CVT transmission means: The Toyota 10-speed CVT transmission is essentially a combination of what is referred to as an ECVT transmission and a 4AT transmission, forming ten gears. The ECVT is quite similar to an AT transmission; rather than being just a transmission, it is more like a highly complex drivetrain system, typically used in Toyota's hybrid models. In this 10-speed CVT transmission, the ECVT provides three fixed gear ratios, which are combined with the first three gears of Toyota's 4AT transmission to form gears 1 through 9. The highest gear of the 4AT then matches the highest gear of the ECVT, creating the tenth gear. The Toyota 10-speed CVT can be seen as a hybrid product of a 4AT and an ECVT.
