Fuel savers are useful for cars. Relevant information about fuel savers is as follows: Function of Fuel Savers: The fuel-saving effect of fuel savers can easily achieve an average range of 5-10%. Installed in vehicles, fuel savers are devices that help reduce fuel consumption through certain methods or techniques. Principle of Fuel Savers: The principle of a car fuel saver involves utilizing the vehicle's own generator power source, automatically generating the required current for the water-powered fuel saver through a power controller. The water-powered fuel saver electrolyzes water inside its main unit into hydrogen and oxygen. The hydrogen-oxygen mixture is then delivered to the engine cylinders via a safe isolation water supply and piping system, where it combusts along with other fuels to enhance performance and achieve fuel-saving purposes.

From my years of experience in the automotive repair industry, fuel-saving devices for cars are actually not very useful. Common products on the market, such as magnetic fuel savers or vortex generators, claim to optimize fuel combustion. However, car engines are already precision systems designed for maximum efficiency. Aftermarket devices may interfere with sensors or circuits and even cause malfunctions. I’ve seen many car owners install these gadgets only to find their fuel consumption increased instead of decreased, ultimately costing them extra money to remove them. If you really want to save fuel, it’s better to maintain good driving habits—such as smooth acceleration, avoiding sudden braking, or regularly servicing your car with oil and filter changes. These small actions can add up to significant savings over a year without harming your vehicle. Ultimately, engine mechanics are complex, and expecting a cheap device to drastically reduce fuel consumption is nothing short of a fantasy. Remember, technological advancements follow scientific principles—don’t be fooled by exaggerated advertising.

What to Do If You Lose the Key Code

You can find the code in the instruction manual. If the key is lost, you should immediately notify the 4S store to have a new key made. For safety reasons, it's best to replace the lock cylinder as well. Below are detailed solutions for lost car keys: Mechanical Key Lost: The main key and the spare key of a mechanical key are identical. If the main key is lost, you can buy a key blank and have a new key cut based on the spare key. However, if someone finds the lost key, they can easily open the door and start the vehicle. Therefore, in such cases, it's best to replace all the locks on the car. Remote Control Key Lost: Essentially, a regular remote control key is just a remote control plus a mechanical key. If one remote control is lost, you only need to take the spare remote control and a newly purchased one to the 4S store to have them rematched with the car. The lost remote control will then become invalid. Chip Key Lost: Many car models now have a chip inside the key for engine immobilization. If a chip key is lost, you can buy a new key and take both the spare key and the new key to the 4S store for rematching. In this case, anyone who finds the lost key can only use the mechanical key to open the door but cannot start the engine. Of course, the most thorough solution is still to replace the mechanical lock.

What Are the Car Maintenance Items and Intervals?

Car maintenance items include: engine oil and engine oil filter replacement, air filter replacement, fuel filter replacement, pollen filter replacement, spark plug maintenance and replacement, transmission oil-related system inspection items, and maintenance. The car maintenance intervals are: 10,000 kilometers is considered minor maintenance, while 20,000 kilometers is considered major maintenance. The benefits of car maintenance include: 1. Ensuring the vehicle operates in optimal performance condition; 2. Improving vehicle efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle malfunctions; 5. Reducing noise and environmental pollution; 6. Maintaining a clean vehicle appearance and preventing damage.

Does the Start-Stop Function Harm the Engine?

The start-stop function does not harm the engine. The engine start-stop function is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when needed to continue moving. When the automatic start-stop is activated, the engine will shut off with a slightly firmer press on the brake pedal and will restart when the brake is pressed again. An engine is a machine that converts other forms of energy into mechanical energy, categorized into internal combustion engines, external combustion engines, gas turbines, and jet engines. Methods for engine maintenance include: 1. Using high-quality engine oil; 2. Using qualified coolant; 3. Regularly cleaning the radiator scale; 4. Periodically removing carbon deposits from the car; 5. Timely replacement of the car's three filters; 6. Maintaining a reasonable engine speed.

What is the normal RPM for car startup?

It is normal for a car to start between 1200 RPM and 1500 RPM. In cold seasons, the engine RPM may be even higher because the vehicle could stall if the RPM is too low, and a slightly higher RPM helps warm up the engine faster. However, during a cold start, the RPM should not be too high either, as the lubricating oil may not reach the upper parts of the engine. To minimize wear, keeping the RPM below 2000 is advisable. Solutions for high or low idle RPM: 1. Adjust or replace the throttle position sensor; 2. Clean or replace the idle control valve and perform a basic idle setting using a specialized decoder; 3. Clean and inspect the fuel injectors to ensure proper atomization; 4. Replace the catalytic converter and check for system leaks.

How Many Spark Plugs Does a Vehicle Have?

A vehicle typically has as many spark plugs as it has cylinders, commonly 4, 6, or 8. However, there are exceptions. For example, the Nissan Bluebird U11 and Honda Fit 1.5 engine have two spark plugs per cylinder, meaning a four-cylinder engine in these models has 8 spark plugs. The working principle of a spark plug is to generate an arc between its electrodes through voltage, igniting the air-fuel mixture in the cylinder to maintain normal engine operation. The function of a spark plug is to discharge the high-voltage pulse delivered by the ignition coil, breaking down the air between the two electrodes to produce a spark, thereby igniting the air-fuel mixture in the cylinder.

Is the Mitsubishi Pajero a body-on-frame vehicle?

The Mitsubishi Pajero is a body-on-frame vehicle. A body-on-frame structure refers to a vehicle with a rigid frame, also known as a chassis frame, where the frame and body are flexibly connected via springs or rubber cushions. The engine, part of the transmission system, and the body assembly components are fixed to the frame using suspension devices. Taking the 2020 Mitsubishi Pajero as an example, it belongs to the mid-to-large-size SUV category, with body dimensions of 4900mm in length, 1875mm in width, and 1900mm in height, a wheelbase of 2780mm, a fuel tank capacity of 88 liters, and a curb weight of 2155kg. This model is equipped with a 3.0L naturally aspirated engine, delivering a maximum horsepower of 174PS, a maximum power output of 128kW, and a maximum torque of 255Nm, paired with a 5-speed automatic transmission.
