2021 bi-fuel vehicle models include the Elysee, Dongfeng Fengshen S30-CNG, and Emgrand. Introduction to Bi-Fuel Vehicles: Bi-fuel vehicles are equipped with two fuel supply systems: one supplies natural gas, and the other supplies liquefied petroleum gas. These two fuel supply systems deliver fuel to the combustion chamber in a predetermined ratio, where the fuels mix and burn inside the cylinder. Advantages of Bi-Fuel Vehicles: They provide stable combustion without knocking and offer convenient cold and hot starts. The storage, transportation, decompression, and combustion of compressed natural gas (CNG) occur under strict sealing conditions, minimizing the risk of leaks. Additionally, the gas cylinders undergo various destructive tests, ensuring safety and reliability. CNG combustion is safe, produces less carbon deposits, reduces vapor lock and knocking, and helps extend the lifespan of engine components. This leads to fewer maintenance requirements and significantly lowers maintenance costs. It also reduces engine oil consumption. Compared to gasoline, using CNG can greatly decrease emissions of carbon monoxide, sulfur dioxide, carbon dioxide, and other pollutants.

What are the reasons why the Kia K5 won't start?

The reasons why the Kia K5 won't start are: 1. The car battery is low on power. 2. Low temperature causes the viscosity and rotation speed of the car engine oil to decrease. 3. There is an issue with the ignition system. 4. Insufficient fuel in the car. 5. Excessive carbon deposits inside the vehicle's engine. 6. The fuel pump is damaged, preventing fuel from the fuel tank from being supplied for combustion. Taking the 2020 Kia K5 as an example, here is its introduction: 1. The front suspension of the 2020 Kia K5 is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. 2. The 2020 Kia K5 is equipped with a 1.5L inline 4-cylinder turbocharged engine, with a maximum horsepower of 170ps, a maximum power of 125kw, a maximum torque of 253nm, and is paired with a 7-speed dual-clutch transmission.

What does the mode button in a car mean?

Mode button in a car is commonly found on the multifunction steering wheel and the center console. When the mode button is on the multifunction steering wheel, it is used to switch between different multimedia modes, such as FM radio, AM radio, CD, or USB. When the mode button is on the center console, it is used to switch between different air conditioning vent modes, typically cycling through foot-level vents, head-level vents, and windshield defrost modes. Other common buttons in a car include: RES to resume or increase cruise control speed, CANCEL to exit cruise control, and SET to set or decrease cruise control speed.

What to Do When a Vehicle Won't Start After Being Parked for a Long Time?

First, consider that the battery may have been depleted due to prolonged inactivity, unable to power the starter motor, ignition coil, and fuel pump. In this case, an external battery is needed to jump-start the vehicle. Secondly, gasoline has a shelf life of only about one month. After three or four months, the gasoline will have evaporated and deteriorated, becoming essentially unusable. Even if the car starts, it should be driven to a gas station to add fresh fuel and use up the old gasoline. Additionally, it is necessary to replace the engine oil, as used oil can also deteriorate after five or six months. The reasons why a vehicle won't start after being parked for a while are as follows: 1. Insufficient fuel: The fuel gauge shows the level below the red line, making it impossible to start. 2. Dead battery: This could be due to the battery being drained from leaving the headlights on or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every two years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause electrical faults in the vehicle. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If left in R (Reverse) or D (Drive), the vehicle won't start. Some manual transmission vehicles may also fail to start if the clutch pedal is not depressed.

Which is More Fuel-Efficient, 1.2T or 1.5T?

Under the premise of the same car brand, the 1.2-liter engine is inevitably more fuel-efficient. Both being turbocharged engines, a smaller displacement and lower power naturally result in lower fuel consumption. A larger displacement means the engine releases more energy and operates more efficiently per unit of time. The greater the power, the higher the fuel consumption. More details are as follows: 1. To compare the fuel efficiency, power, or performance of engines, it must be done under the same technical level, and there are significant differences in engine technology among different brands. Fuel efficiency and performance are inherently opposing factors, which is something car owners need to weigh carefully. Generally, a larger displacement means greater power and stronger performance, but fuel consumption mainly depends on the output power, which essentially reflects the fuel injection volume. 2. Generally, the larger the displacement, the higher the fuel consumption. However, there is no direct conversion formula between the two because many factors affect fuel consumption, many of which cannot be quantified. Factors influencing fuel consumption are numerous, not limited to the engine's powertrain but also include the transmission, drag coefficient, vehicle weight, and tires. Additionally, driving habits, vehicle condition, and road conditions play crucial roles.

Can You Still Drive When the Tire Pressure Yellow Light Comes On?

You can still drive when the tire pressure yellow light comes on, but it is best to pull over safely and check the tires. If you have a tire pressure monitoring tool, you can check whether the pressure in all tires is normal. If you don’t have a tire pressure detector, you can inspect the tires manually. Tires play a significant role in driving safety, and a sudden blowout at high speed could lead to disastrous consequences. The tire pressure warning symbol resembles a jar shape with an exclamation mark inside. This warning light illuminates whenever there is a change in the tire pressure. Tire pressure refers to the air pressure inside the tires, and its level has a crucial impact on the performance and power of the vehicle.

How to Check the Tire Manufacturing Date?

Methods to check the tire manufacturing date: 1. The manufacturing date of the tire can be found on the outer sidewall of the tire, where there is a set of four-digit numbers in an elongated oval shape at the end of the letters DOT; 2. The first two digits represent the week of the year, and the last two digits represent the year. For example, 1713 indicates that the tire was manufactured in the 17th week of 2013; 3. If you cannot find these corresponding marks on the tire, it means the tire is installed backward. For instance, a mark like 3907 represents the manufacturing date as the 39th week of 2007. Check whether the tire's manufacturing date matches the car's purchase date. If the dates differ significantly, it may indicate an issue. If you are buying a car, also pay attention to the tire's manufacturing date mark.
