What are the principles of various transmissions?

Transmission working principles are as follows: 1. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. 2. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations. The torque converter is the most distinctive component of an AT, consisting of a pump impeller, turbine, and guide wheel, directly inputting engine power to transmit torque and perform clutch functions. 3. If liquid is used instead of air as the medium for transmitting kinetic energy, the pump impeller will drive the turbine to rotate through the liquid, with a guide wheel added between the pump impeller and turbine to improve liquid transmission efficiency. Since the torque converter's automatic speed and torque variation range is not large enough and efficiency is relatively low, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system automatically operates the planetary gears according to engine working conditions, thereby achieving automatic gear shifting.

Is the GTR Truly a Supercar?

In terms of performance, the GTR undoubtedly qualifies as a top-tier supercar. However, a supercar is not merely about piling on performance specs. Historically, the GTR's predecessors were high-performance sports sedans under the Skyline series, not supercars. Here’s more about the GTR: 1. The Nissan GTR refers to a high-performance, high-reliability, high-power sports car produced by Nissan. After years of evolution and refinement of Nissan's Skyline sedan series, the GTR model emerged, becoming the pinnacle of the series and adored by countless fans. 2. The entire GTR lineup is equipped with a 3.8-liter V6 twin-turbocharged engine, delivering exceptional power with a maximum output of 357 kW and a peak torque of 588 Nm.

What does the faucet symbol on the car mean?

The faucet symbol on the car's dashboard is the engine malfunction indicator light. If it stays on, it indicates issues with the engine's combustion state, such as engine knocking, poor fuel quality, or unclean engine cylinders. Common causes include: 1. Poor contact or damage to the oxygen sensor, preventing the computer from identifying the engine's combustion state and causing partial failure of emission control functions. 2. Damage or poor contact in the camshaft or crankshaft sensors, leading to incorrect ignition timing, incomplete fuel combustion, and severely reduced efficiency. 3. Poor contact or parameter changes in the throttle motor, throttle sensor, air flow sensor, or absolute pressure sensor, causing the computer to inaccurately judge the air supply and resulting in incorrect fuel mixture ratios and incomplete combustion. 4. Resistance changes in the coolant temperature sensor, causing improper electronic fan activation times, deviating engine operating temperatures from specified values, or leading to high temperatures that reduce cylinder and pipe sealing, lowering engine efficiency. 5. Impurities or water in the fuel, increasing pollutants in the cylinders, causing poor spark plug discharge, incomplete combustion, and non-compliant emissions. 6. Coolant leaks, raising temperatures in various engine parts and altering sensor parameters. 7. Poor contact in the fuel pump, causing poor fuel injection and incomplete engine combustion.

Is the Engine Auto Start-Stop Technology Fuel-Efficient?

Overall, the engine auto start-stop technology is fuel-efficient, especially in urban or congested road conditions. The engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light). When it's time to move forward again, the system automatically restarts the engine. Here are some details about the engine auto start-stop technology: 1. By integrating an enhanced motor with idle start-stop functionality into a traditional engine, the car can completely shut off the engine when idle stop conditions are met. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's command, rapidly restarting the engine for seamless transition, thereby significantly reducing fuel consumption and exhaust emissions. 2. This technology can save up to 5% of fuel under normal driving conditions and up to 15% in congested traffic.

What is the function of an air filter?

The function of an automotive air filter is to filter out dust and particulate matter from the air, ensuring that a sufficient amount of clean and dry air enters the cylinders. The air filter is installed in front of the carburetor or intake pipe and is used to filter the air entering the engine. During operation, the engine inhales a large amount of air, which contains many dust particles. If the air is not filtered by the air filter, it can accelerate the wear of the piston group and cylinders. If larger particles enter between the piston and cylinder, it can cause cylinder scoring. Types of air filters: According to the filtration principle, air filters can be divided into several types: filtration type, centrifugal type, oil bath type, and composite type. The commonly used air filters in engines include inertial oil bath air filters, paper dry-type air filters, and polyurethane filter element air filters. The inertial oil bath air filter undergoes three stages of filtration: inertial filtration, oil bath filtration, and filtration-type filtration. The latter two types of air filters mainly rely on the filter element for filtration. The inertial oil bath air filter has advantages such as low intake resistance, adaptability to dusty and sandy working environments, and a long service life. Methods to determine if an air filter is dirty are as follows: You can observe the engine's operating condition. If the air filter is dirty, the intake air volume will be insufficient, leading to incomplete fuel combustion, which causes unstable engine operation. When continuously pressing the accelerator pedal, the engine sound becomes muffled, acceleration response is sluggish, operation is weak, and the exhaust gas is thick and black. You can check the surface color of the air filter. If the filter paper remains gray-black after cleaning the dust from the surface, it indicates that the filter paper can no longer be used and should be replaced immediately.

What engine does Hongqi use?

Hongqi's engines are all domestically produced, manufactured by Tianjin FAW Toyota Engine Factory. Hongqi primarily uses the CA4GC engine series. For example, the Hongqi HS5 is equipped with a 2.0T all-new CA4GC inline four-cylinder turbocharged engine, paired with a 6-speed automatic transmission, delivering a maximum power of 165kW and a maximum torque of 340Nm. For daily maintenance of Hongqi engines, the following methods are recommended: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent faults, change the oil periodically based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing through the relief valve and carrying contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Periodically use radiator cleaner to flush the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.
