Which cars have unibody construction?

Unibody construction vehicles include the Crown, Reiz, Corolla, Vios, Toyota Prado, Vezel, Corolla, and Dongfeng Peugeot 5008, among others. Unibody construction does not have a separate frame; the body itself serves as the mounting base for the engine and chassis components, functioning as the frame and bearing all loads. For large buses with unibody construction: the basic unibody design makes the lower part of the body side panels below the waistline the main load-bearing component, with longitudinal and transverse members at the bottom typically made from thin-walled steel sections and sheets. For passenger cars with unibody construction: the front end is composed of a rigid frame, the middle section forms a box structure with left and right side panels, floor, roof, front panel, and windshield frame, and the rear end is integrated with the luggage compartment floor and inner and outer rear wheel housings.

When is it necessary to perform a four-wheel alignment for a car?

Cars must undergo a four-wheel alignment in the following situations: 1. Damage to the chassis and suspension caused by an accident; 2. When the vehicle's driving performance is affected, manifested as the vehicle pulling to one side or the steering wheel not returning to center automatically. Four-wheel alignment is based on the vehicle's four tires, adjusting the caster angle, kingpin inclination angle, camber angle, toe-in of the front wheels, and toe-in of the rear wheels to achieve a relatively balanced state among the four tires, thereby improving the vehicle's driving stability. The interval for performing a four-wheel alignment varies depending on the vehicle. For vehicles frequently driven in good road conditions, a four-wheel alignment every 30,000 to 40,000 kilometers is sufficient. However, for vehicles often driven on rough roads, the interval should be appropriately shortened, requiring a four-wheel alignment every 20,000 to 30,000 kilometers.

Does the Fuel System Need Cleaning?

Fuel system cleaning is necessary for the following reasons: 1. Fuel inherently contains colloids, impurities, dust, and moisture, which can form sludge deposits in areas like the fuel tank and fuel lines over time; 2. Carbon deposits and sediments can clog fuel injector needle valves and valve orifices, impairing the performance of precision components in the fuel system, leading to poor fuel injection, inadequate atomization, and reduced power performance; 3. Carbon deposits and sediments may cause intake valves to close improperly, resulting in decreased cylinder pressure or even backfiring, leading to unstable engine idling, increased fuel consumption, and worsened exhaust emissions. It is recommended to periodically use high-quality throttle or intake system cleaners to remove colloids and deposits from the throttle body and intake pipes, as well as carbon buildup from intake valves, combustion chambers, and the three-way catalytic converter, restoring normal compression ratio.

What is the fuel consumption per 100 kilometers for the Buick Excelle?

The Buick Excelle currently has 3 models on sale, including the 2020 15N Manual Elite, 2020 15N CVT Elite, and 2020 15N CVT Luxury models, all equipped with a 107-horsepower engine, with an NEDC fuel consumption of 4.7L per 100 kilometers. The fuel tank capacity varies among different models of the Buick Excelle. The distance that can be covered on a full tank of fuel is as follows: For models equipped with a 107-horsepower engine, the fuel tank capacity is 40L, and the distance that can be covered on a full tank is 40/4.7*100=851KM. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during a cold start, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, in low temperatures, the engine computer controls the car to run at higher RPMs to warm up, which also increases fuel consumption.

What grade of gasoline should a Land Cruiser use?

Land Cruiser should use 95-octane gasoline, as this is the recommended grade specified in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, the Land Cruiser's fuel tank cap also indicates the recommended grade. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade. High-compression engines can also be tuned to use lower-octane gasoline because factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane rating and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Land Cruiser occasionally uses the wrong gasoline grade, simply switch back to the correct grade after refueling. However, long-term use of the wrong gasoline grade can have the following effects: Using a higher-octane gasoline in a vehicle designed for lower-octane fuel will not cause damage, but the increased octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower-octane gasoline in a vehicle designed for higher-octane fuel can cause engine knocking. The significantly lower octane rating lowers the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unevenly. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues. The vibrations not only affect driving stability but can also cause abnormal wear on pistons and cylinders, potentially leading to severe engine damage.

Can motorcycles go on highways in Fujian in 2021?

According to Article 26 of Chapter 4 on Traffic Safety Management in the Fujian Expressway Regulations, motorcycles are not allowed on expressways in Fujian. Issues to pay attention to when riding motorcycles in urban areas are as follows: Watch the driver's head and rearview mirrors in traffic: The driver's head movements are a beat earlier than the turn signals and steering wheel. Observing the driver's head movements directly or through the car's rearview mirrors can intuitively predict the driver's next move. Be cautious of sudden braking or lane changes: For taxi drivers, the probability of accidents is higher than for regular drivers because they divert some of their attention to looking for passengers on the roadside. So, when behind a taxi displaying an "available" status, be wary of sudden braking or lane changes. Be mindful of blind spots: Cars have many blind spots, making them hazardous in urban traffic. Large vehicles like buses and cement mixers are even more dangerous due to their narrower fields of vision. Highway driving precautions: Maintain a steady speed: After passing the highway toll booth, drive in the acceleration lane first, check for approaching vehicles from behind, and merge into the travel lane without disrupting the normal flow of traffic. Keep a steady speed and maintain a safe distance from the vehicle ahead, referring to distance markers. Generally, if the speed is 100 km/h, the distance should be 100 meters. Stay in one lane: Avoid frequent lane changes on the highway and never make sudden, unannounced stops in the travel lane. Do not drive side by side with other vehicles or linger in the passing lane. Never attempt to overtake from the emergency lane. Additionally, when exiting or merging, prepare early—slow down and move to the right lane or deceleration lane 500 meters before the exit or merge point. Avoid sudden turns or emergency braking at the last moment. Overtake decisively: When deciding to overtake, check for vehicles approaching from the left rear and ensure there are no obstacles in the passing lane. Use the horn or lights to alert the vehicle being overtaken, especially trucks or buses, and accelerate decisively. After overtaking, do not return to the travel lane immediately; wait until you are 50-100 meters past the overtaken vehicle before signaling to merge back. Exercise caution when driving at night: Use high beams when driving on highways at night, watch for taillights of vehicles ahead, and avoid fatigue driving. In case of heavy fog at night, reduce speed and turn on hazard lights. Overcome adverse weather conditions: Visibility is poorer in rain, increasing the risk of accidents on highways. Slow down and watch for standing water, which can cause hydroplaning and loss of control. Avoid sudden braking and sharp steering, and maintain twice the usual following distance. Use proper warnings when stopping: If you need to pull over due to a breakdown, signal early with the right turn indicator, move to the emergency lane or shoulder, and never stop in the travel lane. Turn on hazard lights and place a warning sign 150 meters behind the vehicle.
