Why does the new Santana dual-fuel vehicle suddenly fail to run on gas?

Dual-fuel vehicle cannot run on gas, possibly due to low gas pressure, and the power when running on gas is not as strong as when running on gasoline. Introduction to dual-fuel vehicles: Equipped with two sets of fuel supply systems, one supplying natural gas and the other supplying liquefied petroleum gas. The two fuel supply systems deliver fuel to the combustion chamber according to a predetermined ratio, where the fuels mix and burn inside the cylinder. Advantages of dual-fuel vehicles: Stable combustion without knocking, and easy cold and hot starts. The storage, transportation, decompression, and combustion of compressed natural gas are carried out under strict sealing conditions, making leakage unlikely. Additionally, the gas cylinders undergo various special destructive tests, ensuring safety and reliability. Compressed natural gas burns safely, produces less carbon deposits, reduces vapor lock and knocking, which helps extend the service life of various engine components, reduces the frequency of maintenance, and significantly lowers maintenance costs. It can also reduce the engine's oil consumption. Compared to gasoline, using compressed natural gas can significantly reduce emissions of carbon monoxide, sulfur dioxide, carbon dioxide, etc.

What to Do If the Mitsubishi ASX Has High Fuel Consumption?

Here are some solutions for high fuel consumption in the Mitsubishi ASX: 1. Regularly clean the air filter to ensure the engine breathes fresh air and maintains smooth airflow in the intake system. 2. Periodically inspect and replace spark plugs in the ignition system, as a strong spark is essential for complete combustion of the air-fuel mixture. 3. The fuel system should also be cleaned regularly, as carbon buildup on the fuel injectors can cause needle valve leakage, leading to fuel wastage. 4. The engine should undergo periodic carbon deposit cleaning, as excessive buildup can disrupt accurate fuel control and increase fuel consumption.

What Causes Difficulty in Cold Starting a Car Engine?

Here are the specific reasons for difficulty in cold starting a car: 1. Excessive carbon deposits leading to frequent malfunctions. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start the engine. Only when the carbon deposits become saturated with gasoline does the engine start more easily. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. This fluctuation between lean and rich mixtures causes the engine to idle roughly after a cold start. 2. Low engine temperature. When the engine temperature is too low, the fuel and lubricating oil do not reach the required temperature, so more fuel should be injected during cold starts to meet performance demands. Poor fuel atomization at low temperatures leads to reduced ignition energy, affecting performance and causing the car to shake. Aging ignition coils, spark plug high-voltage wires, or electrical leakage can also reduce ignition energy.

What Causes the Odor When Turning on the Car Air Conditioner?

Mold growth and humid air are the causes of odors in the air conditioning system. The specific details are as follows: Humid Air: Due to prolonged lack of cleaning of the air filter, combined with humid air during rainy seasons, the air filter becomes damp and warm, leading to mold growth and a musty smell. Mold Growth: Outside air flowing through the air conditioning system ducts inevitably brings moisture and dust. Most of the moisture and dust are expelled from the vehicle through the air conditioning drain, but a small amount of residual moisture in the air conditioning ducts combines with dust from the air. If not cleaned for a long time, this can lead to mold growth, producing sour and rotten odors. Solutions: Regularly clean the air conditioning system or replace the air filter to reduce mold growth; master the correct method of turning the air conditioner on and off. It is generally best to turn off the air conditioning cooling 5 minutes before parking, then switch to natural air to allow the interior temperature to rise quickly. This prevents water condensation in the air conditioning ducts due to temperature differences after parking, keeping the ducts dry and blocking mold and fungus growth. Using natural "air fresheners," such as placing fruits like pineapple, lemon, or apple in the car, can help eliminate odors.

Can Tap Water Replace Windshield Washer Fluid?

Tap water cannot replace the function of windshield washer fluid. Because water contains impurities, it can easily clog the washer fluid nozzles. When purchasing windshield washer fluid, avoid low-quality products as they can accelerate wiper blade aging. Additionally, prolonged use of tap water to clean the windshield may increase friction between the windshield and wiper blades, leading to scratches on the glass surface. Moreover, tap water can only remove surface dust and is ineffective against other dirt and insect residues. In summer, you can use concentrated wiper fluid as a substitute. Add the concentrated wiper fluid to water, shake it thoroughly, and then pour it into the vehicle as windshield washer fluid. Windshield washer fluid contains specific cleaning agents that effectively clean the glass, which tap water lacks. Therefore, the proper substitute is concentrated wiper fluid, not tap water. Use dedicated windshield washer fluid in winter: During winter, it is essential to use specialized windshield washer fluid with a low freezing point. Otherwise, the fluid may freeze due to low temperatures. When liquids freeze, their volume expands, which can damage the washer fluid reservoir. Windshield washer fluid offers the following features: Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, effectively removing dirt. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing fog droplets and ensuring clear visibility. Lubrication performance: The ethylene glycol in the fluid has high viscosity, providing lubrication to reduce friction between wiper blades and the glass, preventing scratches. Anti-corrosion performance: The fluid contains multiple corrosion inhibitors, ensuring it does not corrode any metals, car paint, or rubber, making it completely safe.

What Causes the Steering Wheel to Feel Heavier?

There are several reasons why a car's steering wheel may feel heavier: 1. Insufficient power steering fluid. Power steering fluid is a medium oil used in the car's power steering pump to transmit steering force and provide cushioning. It needs to be replaced regularly, and any leaks should be checked. When the power steering fluid is insufficient, the steering wheel may feel heavy and stiff. 2. Low tire pressure. Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. 3. Toe-in issues. Toe-in can also affect the car's steering. Toe-in helps the steering wheels automatically return to the correct position, ensuring stable straight-line driving. Problems in this area can also cause the steering wheel to feel heavy. 4. Malfunction of the steering gear or power steering pump. The steering gear and power steering pump are also critical components affecting the car's steering. Any malfunction in these parts can make steering difficult. Issues such as universal joints, chassis suspension stabilizer bars, or plain bearings should not be overlooked. 5. Overly tight bearing fit. If the rolling bearings or sliding bearings in the steering system are too tightly fitted, it can lead to poor lubrication and cause sticking or resistance.
