How Does E-CVT Work?

E-CVT is essentially a planetary gear structure combined with two drive motors. In this setup, the sun gear is connected to Motor 1, the planetary carrier is linked to the engine flywheel, and the ring gear is simultaneously connected to Motor 2 and the E-CVT output shaft. By leveraging the speed relationships among the components of the planetary gear structure, continuous variation of the transmission ratio between the engine flywheel input shaft and the ring gear output shaft is achieved. Relevant details are as follows: 1. Introduction: E-CVT is not an official term; it originates from Toyota's Hybrid Synergy Drive (HSD) hybrid system, which is a power-splitting device (Power Splitting Device) based on the improved Toyota Hybrid System (THS) planetary gear set. 2. Function: Due to its similarity in driving experience to traditional CVT transmissions and the need for clear classification in production regulatory catalogs, Toyota coined the alias "E-CVT" for the HSD power-splitting structure.

What does unreasonable crankshaft top dead center missing tooth signal mean?

Unreasonable crankshaft top dead center missing tooth signal is the reference signal for fuel injection and ignition control; Normally, the crankshaft's rotating disk is evenly distributed with (60-2) teeth, among which there are two missing teeth. When the crankshaft sensor identifies the missing teeth, the pulse transmitted to the engine controller will widen. After the engine controller recognizes this signal, it knows that the top dead center of the compression stroke of cylinder 1 or 4 is approaching, and prepares for ignition. The following are several reasons for the fault of unreasonable crankshaft top dead center missing tooth signal: 1. Crankshaft sensor failure: It can be excluded by replacing the crankshaft sensor and then testing. 2. Displacement of the engine's crankshaft disk: This requires disassembly to check for damage and can be excluded after reinstallation. 3. Severe wear of the engine crankshaft: This fault may occur.

What is the fuel consumption parameter of the Hongqi HS5?

The fuel consumption range of the Hongqi HS5 is 7.6-11.2L/100km, with an average fuel consumption of 10.7L/100km. The actual fuel consumption mainly depends on the specific driving conditions and the driver's habits, as there are many complex factors affecting fuel consumption. Below are some tips to reduce fuel consumption: 1. Start slowly: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. 2. Maintain proper tire pressure: Keep the tire pressure at the level recommended by the manufacturer. 3. Regularly organize the trunk and reduce weight: Extra items increase the vehicle's weight, thereby increasing fuel consumption.

What Causes the Friction Noise When Driving at Low Speed?

The cause of friction noise when driving at low speed needs to be determined by identifying the location of the abnormal sound. Here are the relevant explanations: 1. Near the tires: If the abnormal sound occurs near the tires and the wheels and bearings have been ruled out, it may be caused by friction between the brake pads and brake discs. Generally, brake pad noise is mostly due to hard spots on the brake pads rubbing against the brake discs, producing noise. Minor noises can be ignored; if the noise is loud, the brake pads can be removed, sanded with sandpaper, and reinstalled, which usually resolves the issue. 2. Connection between the transmission and engine: If the noise comes from the connection between the transmission and engine, it may be caused by damage to the clutch plate or release bearing. If the noise is inside the transmission, it could be due to abnormal wear of the first or second gear.

What are the main things to know when buying a car?

First, determine your needs—whether to choose an SUV or a sedan, what your budget is, and identify target models. It's best to visit the dealership for a test drive to get a feel for the car. Finally, handling the license plate registration yourself would be perfect. Below is more detailed information: 1. Budget: Your budget helps narrow down the general price range you can consider. Typically, people tend to stretch their budget upward rather than downward. For example, it's common for someone with a 100,000 RMB budget to end up buying a 150,000 RMB car. You also need to decide whether to buy a new or used car and whether to pay in full, borrow money, or take out a loan. 2. Needs: Personal preferences are subjective and broad, so it's important to focus on practical needs. Consider who will be driving the car, its primary purpose, and whether there are elderly or children in the family. If you frequently travel with family, an SUV is recommended for its better visibility, stability, and spacious rear seats. No car is perfect—you'll often have to make trade-offs between comfort and sportiness, power and fuel efficiency. Additionally, research the costs of future maintenance in advance. 3. Test Drive and Ride: Before buying a car, take it for a test drive and ride to get the most direct experience. Try multiple cars, as even models with similar specs can feel vastly different when driven. Many aspects, such as brake sensitivity (some require a light touch, others a firmer press) or throttle response (some are jumpy, others sluggish), can only be judged through personal experience. For instance, some cars feel more comfortable in the front seats, while others prioritize rear-seat comfort. Many people focus on test driving but overlook test riding, where a dealership professional demonstrates the car's features and selling points. Therefore, it's advisable for prospective buyers to take two laps at the dealership: one for test driving and one for test riding.

What are the symptoms of a damaged fuel metering unit?

The symptoms of a damaged fuel metering unit in an electronically injected diesel vehicle include the illumination of the malfunction indicator light, and continued use may lead to the engine failing to operate properly. Relevant information is as follows: 1. Introduction: It is installed at the fuel inlet of the high-pressure fuel pump to adjust the fuel supply volume and fuel pressure value, controlled by the ECU. 2. Component: The fuel metering unit is a precision component. Also known as the fuel metering proportional valve, it is installed on the inlet side of the high-pressure fuel pump. In simple terms, it is a special solenoid valve, unique in that its opening can be controlled by the engine computer at any position during its stroke to regulate the volume of fuel entering the plunger chamber of the high-pressure fuel pump.
