What engine does Changan Oushang use?

Changan Oushang's engine is independently produced by Changan Company, with its production base located in Chongqing, making it a domestically manufactured engine. In the Changan Oushang series, the Oushang X7 is equipped with the JL476ZQCF engine model, featuring a maximum power of 131kW, maximum horsepower of 178, and maximum torque of 265Nm. The 1.5T version of the Oushang X5 uses the Blue Whale NE1.5T engine model, delivering a maximum power of 132KW, maximum torque of 300Nm, and maximum horsepower of 180. For daily maintenance of Changan Oushang's engine, the following methods can be applied: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine issues. 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 becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and 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. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

How Many Kilograms is 20 Liters of Gasoline?

The weight of 20 liters of gasoline ranges between 28 to 31.2 kilograms. The density of gasoline varies slightly depending on the type of gasoline and seasonal climate, with gasoline density ranging from 0.70g/cm³ to 0.78g/cm³. If the gasoline density is taken as 0.70g/cm³, then 20*0.70=14=28 kilograms. If the gasoline density is taken as 0.78g/cm³, then 20*0.78=15.6 kilograms=31.2 kilograms. The weight of gasoline itself also depends on temperature. Due to different seasonal climates, the density of gasoline changes slightly. When the temperature rises, the volume of each liter of gasoline increases, and the density decreases. When the temperature drops, the density of each liter of gasoline increases, and the volume decreases. This means that the same liter of gasoline has different weights and densities in different temperature seasons. Therefore, the mass of 1 liter of 92-octane gasoline should be m=0.725g/ml*1000ml=0.725kg=1.45 kilograms; the density of 95-octane gasoline is 0.737g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.737g/ml*1000ml=0.737kg=1.47 kilograms; the density of 90-octane gasoline is 0.72g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.72g/ml*1000ml=0.72kg=1.44 kilograms; the density of 93-octane gasoline is 0.725g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.725g/ml*1000ml=0.725kg=1.45 kilograms; the density of 97-octane gasoline is 0.737g/ml, so the mass of 1 liter of 95-octane gasoline should be m=0.737g/ml*1000ml=0.737kg=1.47 kilograms. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Its main components are C5~C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is divided into common grades such as 92, 95, and 98 based on octane levels. The calorific value of gasoline is approximately 44000 kJ/kg. The ignition point of gasoline is between 415-530°C. The surface of gasoline is a transparent liquid and is flammable. Gasoline usually contains mechanical impurities and water. Mechanical impurities can cause serious consequences such as clogged fuel lines and increased wear. Important characteristics of gasoline include volatility, stability, anti-knock properties, corrosiveness, and cleanliness. When adding gasoline, car owners can check the appropriate gasoline grade in the car manual or on the fuel tank cap, which is usually marked. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and those with higher compression ratios should use 98-octane gasoline. However, with the use of some new technologies, the gasoline grade cannot be determined solely based on the compression ratio. High compression ratios can also be adjusted to use lower-grade gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role.

Does the Baojun 310 have a rear anti-collision beam?

Baojun 310 has a rear anti-collision beam. The anti-collision beam is a device designed to absorb collision energy and reduce the impact force on the vehicle's longitudinal beams during low-speed collisions. It serves as a buffer in the event of an accident, rather than directly protecting the vehicle. The Baojun 310 is a compact hatchback with dimensions of 4032mm in length, 1680mm in width, and 1450mm in height, and a wheelbase of 2550mm. It offers two different powertrain options: a 1.2L naturally aspirated engine and a 1.5L DVVT naturally aspirated engine, paired with a 6-speed manual transmission and a 5-speed automated manual transmission, respectively.

What does high speed mean?

High speed refers to the fast speed of a vehicle. Below is a detailed introduction about it: 1. Introduction 1: Speed limits for small passenger vehicles should not exceed 120 km/h, other motor vehicles should not exceed 100 km/h, and motorcycles should not exceed 80 km/h. 2. Introduction 2: Minimum speed limits When driving normally on highways, the minimum speed should not be less than 60 km/h. For roads with two lanes in the same direction, the minimum speed in the left lane is 100 km/h. For roads with three or more lanes in the same direction, the minimum speed in the leftmost lane is 110 km/h, and the minimum speed in the middle lane is 90 km/h.
