What are the effects of mixing E92 and 92 gasoline?

92 gasoline and 95 gasoline cannot be mixed because they have different iso-octane contents. 92 gasoline is suitable for engines with low compression ratios, while 95 gasoline is suitable for engines with high compression ratios. If 92 gasoline is added to a car that should use 95 gasoline, it may cause abnormal combustion, leading to knocking. Knocking not only damages the combustion chamber but also directly affects the normal operation of the engine, and in severe cases, may cause engine damage. If 95 gasoline is added to a car that should use 92 gasoline, although it will not damage the engine, 95 gasoline is more expensive than 92 gasoline, resulting in unnecessary costs. Differences between 92, 95, and 98 gasoline: Standard gasoline is composed of iso-octane and n-heptane. Iso-octane has good anti-knock properties, with its octane rating set at 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane rating set at 0. If the gasoline is labeled as 92, it means that the gasoline has the same anti-knock properties as standard gasoline containing 92% iso-octane and 8% n-heptane. The same principle applies to 95 and 98 gasoline. What to do if the wrong gasoline is added: If gasoline with a higher octane rating than specified for the car is added, for example, adding 95 when 92 is specified, simply switch back to 92 gasoline after the current fuel is consumed. If gasoline with a lower octane rating than specified for the car is added, for example, adding 92 when 95 is specified, you can add a high anti-knock fuel additive. Alternatively, you can directly drain the fuel and refill with 95 gasoline. To find out which gasoline your car requires, you can refer to the car's user manual or check the fuel grade marked on the fuel tank cap.

What engine is used in the Hanlong Kuangshi car?

The engine of the Hanlong Kuangshi car is produced by the Hubei Daye Hanlong Engine Factory, so it is a domestically produced engine. The engine model of the Hanlong Kuangshi car is TN4A20TDZ, with a maximum power of 160kW, maximum horsepower of 218Ps, and maximum torque of 370N·m. For the daily maintenance of the Hanlong Kuangshi car's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, bypassing the filter and carrying contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What is coodyear tire?

coodyear is Goodyear tire. The Goodyear Tire & Rubber Company was founded in 1898 in the United States and has a history of over a century. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products in over 90 factories across 28 countries. When using coodyear tires in daily life, pay attention to the following points: Regularly check the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tire gradually become shallow. If the tread is worn flat, it will lose its drainage and anti-skid functions, significantly reducing the vehicle's performance. Small cracks may seem minor but can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Try to park on flat ground. Avoid parking the car on roads with thick, sharp, or pointed stones. The car should not be parked near or in contact with petroleum products, acids, or other materials related to rubber deterioration. After parking, the driver should not turn the steering wheel, as this operation will accelerate tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and the air pressure will increase. In such cases, park the car to dissipate heat. It is strictly forbidden to release air to reduce pressure or splash water to cool down, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and emergency braking to prevent accelerated tread wear due to dragging between the tire and the ground.

What are the standard dimensions for a home garage?

Generally, the standard dimensions for a home garage are as follows: 1. Large vehicle parking space: The width is 4 meters, and the length ranges from 7 to 10 meters, depending on the vehicle model. 2. Small vehicle parking space: The width is between 2.2 to 2.5 meters, and the length is 5 meters. 3. Adjacent road for small vehicles: For single-sided parking, the width is 5 meters; for double-sided parking, it is 6 meters; for large vehicles, it is 8 meters. Below is an introduction to garage classifications: 1. Traditional garage: This refers to a brick-and-mortar garage, similar to a house. Also known as a mechanical three-dimensional garage, it uses machinery to store and retrieve vehicles. The entire parking facility is called a mechanical parking garage, and a three-dimensional mechanical parking garage is called a mechanical three-dimensional parking garage. It mainly consists of multi-level space garages, with a single-level flat parking garage as the core. Through microcomputers (via an upper computer), the garage is uniformly managed, monitored, and controlled by PLC to change the spatial position of parking spaces, achieving the transformation from space to plane, thus realizing the function of multi-level flat parking. 2. Mobile garage: A newly emerged type of garage that has no fixed location and can be moved. It is less costly than traditional garages but also has a relatively shorter lifespan. Generally, fabric mobile garages have a lifespan of 3 months, and with no human damage, they can last 1-2 years; all-steel mobile garages have a lifespan of 10-20 years.

Where is the car engine number located?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate or the nameplate inside the engine compartment. You can also check the engine number on the car purchase invoice, the factory certificate, the operation certificate for commercial vehicles, the vehicle purchase tax payment certificate, the registration record with public security authorities, or the vehicle insurance card. The simplest and most direct method is to look at the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle. It contains very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or company practices, and the engine's attributes. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the manufacturer's name, model, and production number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's product line, and multiple engines can share the same model. The engine number, however, is the production number of the engine, and each engine has a unique number. Structure of the engine number: Front part: Includes the product series code, generation symbol, and regional or company code. Manufacturers can choose appropriate letters as needed, but they must be approved and filed by the industry standardization unit. Middle part: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear part: Composed of symbols for structural features and usage characteristics. Tail part: Distinguishing symbol. If differentiation is needed due to improvements or other reasons within the same series, the manufacturer selects an appropriate symbol. The rear and tail parts can be separated by a hyphen.
