Diesel fuel turning black is generally caused by the infiltration of engine oil into the fuel tank. Physical Characteristics: Flammable and volatile, insoluble in water, easily soluble in alcohol and other organic solvents. Main Classifications: Diesel is divided into light diesel and heavy diesel. Light diesel is used as fuel for diesel engines in vehicles such as diesel cars and tractors. Uses: Diesel is widely used in large vehicles, ships, generators, etc. It is mainly used as a liquid fuel for diesel engines. Diesel has the environmental characteristics of low energy consumption and low pollution. Moreover, compared to gasoline, diesel is cheaper and more economical, which is why some small cars and even high-performance vehicles have switched to diesel.

What car brand uses the R logo?

Brands that use the letter R as their logo include Rolls-Royce and Chery Riich. The double R logo of Rolls-Royce is an abbreviation of the names of its two founders, Charles Stewart Rolls and Henry Royce. Riich is the parent brand of Chery Automobile's MPV series, and its logo consists of a pair of spread wings and the initial letter "R" of its English name (RIICH). In addition to manufacturing cars, Rolls-Royce is also involved in the production of aircraft engines and is an excellent engine manufacturer. Some Airbus aircraft models use Rolls-Royce engines, such as the famous Boeing passenger aircraft, which is powered by Rolls-Royce engines. Rolls-Royce models include the Phantom and Cullinan. The Phantom was the first product launched by Rolls-Royce after its acquisition by BMW. Thanks to its all-aluminum body design, the massive car weighs less than 2.5 tons. Combined with the 6.7L V12 engine and 6-speed automatic transmission, the Phantom accelerates from 0-100 km/h in less than 6 seconds. The Cullinan is Rolls-Royce's first SUV model. In appearance, the Cullinan resembles a raised Phantom, with an official top speed of only 185 km/h. Chery Automobile was registered and established in Wuhu, Anhui, in 1997. In 2009, Chery's high-end brand, Riich, was officially launched. Riich targets the mid-to-high-end car market, forming a product layout similar to the symbiotic relationship between Mini and BMW 5 Series, Yaris and Camry, Fit and Accord, with its G series and M series. This has greatly enriched the strength of the Riich brand while also enhancing its competitiveness in the high-end car market.

What is the difference between front and rear caliper positions?

The differences between front and rear caliper positions are as follows: 1. Different definitions: Front calipers - when the vehicle moves forward, the brake disc rotates forward. To stop it, the caliper clamps the brake disc with a force opposite to the direction of rotation. Clearly, the front caliper exerts an upward force. The combination of upward and downward forces makes the car more prone to nose-diving or understeering during braking. Rear calipers - when the brake disc moves forward, the rear brake applies a downward opposing force to clamp the brake disc. As a result, the car's nose moves downward, and the caliper also exerts a downward force. These two forces in the same direction help balance the car's nose. 2. Different performance: Most performance cars have a brake caliper layout where the front calipers are positioned towards the rear and the rear calipers towards the front. If the front caliper is placed at the rearmost position, it will inevitably cause the greatest shift in the center of gravity. Therefore, some vehicles may position the front calipers slightly higher or lower. Positioning them slightly lower can help reduce the vehicle's center of gravity to some extent.
