A compact chassis refers to a vehicle with soft suspension. The chassis serves to support and install the car engine and its various components and assemblies, forming the overall shape of the vehicle. It also receives the power from the engine to enable the car's movement and ensure normal driving. The chassis consists of four main parts: the transmission system, the running gear, the steering system, and the braking system. Below are detailed introductions: 1. Transmission System: The transmission system generally includes the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The power generated by the car engine is transmitted to the driving wheels through the transmission system. The transmission system functions to reduce speed, change gears, reverse, interrupt power, provide inter-wheel differential, and inter-axle differential. Working in conjunction with the engine, it ensures the car's normal operation under various conditions, offering good performance and fuel efficiency. 2. Running Gear: The running gear consists of the car's frame, axles, wheels (note), and suspension. 3. Steering System: The specialized mechanism in a car used to change or restore its driving direction is called the steering system. Depending on the steering energy source, steering systems can be divided into two main categories: mechanical steering systems and power steering systems. 4. Braking System: A series of specialized devices in a car that apply a certain force (mainly from the road surface) to specific parts (mainly the wheels) to enforce a certain degree of braking are collectively called the braking system. Its functions include: forcing a moving car to decelerate or even stop as required by the driver; ensuring a parked car remains stable under various road conditions (including on slopes); and maintaining a stable speed for a car driving downhill.

What is the actual fuel consumption of the Changan CS75 Plus 2.0T?

The comprehensive fuel consumption of the Changan CS75 Plus 2.0T is 8.1L/100km. There are currently two models of the Changan CS75 Plus 2.0T on sale: the Automatic Flagship and the Automatic Navigator, both with a comprehensive fuel consumption of 8.1L/100km. The above figures are NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 9.7-12.0L/100km. When driving, the following five tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: While driving, gently press the accelerator to avoid sudden increases in engine speed and prevent the car from shaking during operation, thus making the car more fuel-efficient. By anticipating road conditions and adopting slow and uniform acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle checks: Regular oil changes can reduce carbon buildup (carbon buildup can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace dirty air filters, clean or replace fuel injectors, spark plugs, and throttle bodies as per mileage. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption.

How often should the spark plugs be replaced for the Sagitar 1.6?

The spark plugs for the Sagitar 1.6 should be replaced every 30,000 to 50,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber and generate a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. A spark plug mainly consists of a terminal nut, insulator, terminal post, center electrode, side electrode, and shell, with the side electrode welded to the shell. The Sagitar is a model under FAW-Volkswagen, with body dimensions of 4544mm in length, 1760mm in width, and 1461mm in height, and a wheelbase of 2578mm. The entire lineup has been upgraded with features such as car networking and an 8.0-inch color LCD instrument panel.

Does a 2017 vehicle require an annual inspection in 2021?

A 2017 vehicle requires the annual inspection procedure in 2021, which is an off-line inspection procedure. It can be processed through the Traffic Management 12123 platform or directly at the vehicle management office or the traffic management department of the public security authority. Both methods effectively handle the vehicle's exemption from physical inspection. Relevant details are as follows: Purpose of vehicle annual inspection: The annual vehicle inspection is a mandatory test for every vehicle that has obtained an official license plate and registration certificate. It is equivalent to an annual physical examination of the vehicle according to the technical conditions for safe operation of motor vehicles, aiming to promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents. The inspection includes: checking for the vehicle's user manual and certificate of conformity, verifying the completeness of factory inspection marks on the vehicle body, measuring the vehicle's external and internal dimensions, wheelbase, and axle track. The inspection is conducted item by item according to technical standards. Upon passing, the initial inspection and modification registration form for motor vehicles is completed, and the vehicle's curb weight, load capacity, passenger capacity, and driver's compartment seating capacity are filled in according to the manufacturer's specifications.

Is it mandatory to install ETC on the windshield?

ETC can be used without being attached to the glass. Installing ETC on the upper part of the windshield is to minimize obstruction of the driver's view while ensuring better recognition by the equipment at highway toll stations. If you prefer not to install it on the glass, place it in an open area where it can be seen through the windshield. For small vehicles, the ETC is generally installed in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed in the lower middle part. The suitable installation height is between 1.2 meters and 2.5 meters, with an installation angle between 30 to 90 degrees. If the vehicle has or will have a blast-resistant film, which may interfere with microwave signal transmission, the ETC should be installed in the microwave window strip. Here are some considerations for ETC installation: Avoid obstructing the view—best installed behind the rearview mirror: Many car models have windshields with a steep incline, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Placing it behind the rearview mirror on the right side helps avoid blocking the view. Ensure unobstructed charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, avoid installing it on the windshield's blacked-out areas or positions that might block the solar panel. Do not remove it once installed: The adhesive backing has an anti-tamper button connected to a switch. Once installed, the windshield presses this button in. If removed, the button pops out, triggering the switch and locking the tag, rendering it unusable until unlocked at an ETC service point. This mechanism prevents multiple vehicles from sharing one device. ETC usage tips: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle ahead due to its faulty ETC device, maintain a distance of over 10 meters. The ETC lane recognition speed is 20 km/h—exceeding this may result in failed transactions. If using a debit card-linked ETC, insufficient balance will cause transaction failures.
