What Causes the Occasional Noise When Engaging Reverse Gear from a Standstill?

What Grade of Gasoline is Suitable for the Sagitar?

The Sagitar should use 95-octane gasoline. This gasoline grade is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it marked on the fuel tank cap. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a 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 even higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade, as high-compression engines can also be tuned to use lower-octane gasoline. This is 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 Sagitar occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the tank is empty. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, accidentally using higher-octane gasoline 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. For vehicles recommended to use higher-octane gasoline, using lower-octane gasoline can cause engine knocking. Due to the significantly lower octane rating, the fuel ignites prematurely during the compression stroke, creating resistance before the spark plug fires. This resistance makes the engine run very unevenly. If the knocking is mild, it may only increase noise without obvious engine damage. However, severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear to the pistons and cylinders, potentially leading to cylinder scoring.

What is the fuel consumption per 100 km for the Changan CS75?

There are 3 models of the Changan CS75. The Changan CS75 2022 Blue Whale Edition 1.5T DCT Premium and Luxury models, both equipped with a 180-horsepower engine, have an NEDC fuel consumption of 6.5L per 100 km. The manual Elite model, also equipped with a 180-horsepower engine, has an NEDC fuel consumption of 6.2L per 100 km. The fuel tank capacity is the same for all Changan CS75 models. The distance that can be covered on a full tank of fuel is as follows: For the Changan CS75 2022 Blue Whale Edition 1.5T DCT Premium and Luxury models, both with a fuel tank capacity of 58L, the distance covered on a full tank is 58/6.5*100=892 km. For the manual Elite model, with a fuel tank capacity of 58L, the distance covered on a full tank is 58/6.2*100=935 km. 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 engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline for combustion. 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, leading to higher fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance, resulting in higher 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 for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Is the fuel consumption of the old Mazda 6 very high?

The old Mazda 6 with a 2.0-liter naturally aspirated engine has a combined fuel consumption of about 10 liters per 100 kilometers, which is relatively high for a 2.0-liter naturally aspirated engine. The old Mazda 6 is a very classic car with many fans in China, and many modification enthusiasts also use this car for modifications. More details about the old Mazda 6 are as follows: 1. Detail one: The old Mazda 6 is equipped with a 2.0-liter naturally aspirated engine with a maximum power of 108kw, a maximum torque of 183 Nm, a maximum power speed of 6500 rpm, and a maximum torque speed of 4000 rpm. This engine uses an aluminum alloy cylinder head and block, and is paired with either a 6-speed manual transmission or a 5-speed automatic transmission. 2. Detail two: The front suspension of this car uses a double-wishbone independent suspension, and the rear suspension uses a multi-link independent suspension. The front suspension also includes a stabilizer bar. The Mazda 6 is called the 'King of Corners' by many car enthusiasts, and its cornering performance is indeed excellent. Although the engine power of this car is not very strong, its chassis tuning is outstanding.

What is the Difference Between Li Auto and NIO?

Li Auto and NIO are introduced as follows: 1. Introduction One: The production of vehicle models differs. Li Auto primarily focuses on extended-range electric vehicles during manufacturing, and its development of vehicle platforms also differs from NIO. From a market positioning perspective, the two companies have different product positioning strategies. NIO's product structure is relatively more diverse compared to Li Auto, with its vehicle models primarily positioned as pure electric vehicles. 2. Introduction Two: NIO centers its services around "user experience" to bridge the gap between users and manufacturers, compensating for the differences caused by the range limitations of pure electric vehicles through aftermarket services. On the other hand, Li Auto's philosophy revolves around "product experience," focusing on addressing the pain points of pure electric vehicles to provide differentiated services, alleviating range anxiety, and emphasizing product quality and usage. 3. Introduction Three: Li Auto and NIO differ in their design approaches for vehicles and their solutions to common vehicle usage pain points. One prioritizes user experience, while the other focuses on product-centric thinking. In summary, as leading new forces in the automotive industry, both NIO and Li Auto prioritize user experience, but each has its own distinct characteristics in various aspects.
