Is Engine Oil Additive Useful?

No, it's not useful. The so-called engine oil additive refers to a type of oil additive produced by some manufacturers, whose ingredients include viscosity index improvers and anti-wear additives, among other things. Here is some relevant information: 1. Overview: Engine oil, also known as engine lubricant, English name: Engine-oil. With a density of approximately 0.91×10³ (kg/m³), it serves to lubricate and reduce wear in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 2. Classification: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the deficiencies in the performance of the base oil, imparting certain new properties, making them an important component of lubricating oil.

What type of engine oil is suitable for the Ford Escort?

The Ford Escort uses 5W30 semi-synthetic engine oil. Engine oil, also known as engine lubricant, is an essential lubricant that ensures the normal operation of the engine. Its functions include lubricating metal components, reducing friction between parts, and dissipating the immense heat generated during engine operation. Types of engine oil include mineral oil, semi-synthetic oil, and fully synthetic oil. Taking the 2019 Ford Escort as an example, it belongs to the compact car category, with body dimensions of 4587mm in length, 1825mm in width, and 1490mm in height, a wheelbase of 2687mm, a fuel tank capacity of 50 liters, and a curb weight of 1265kg. This model is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 122PS, a maximum power output of 90kW, and a peak torque of 152Nm, paired with a 6-speed manual transmission.

What does the wrench light on the car dashboard mean?

The small wrench is a maintenance reminder indicator. This is a maintenance alert function. The owner should take the vehicle to a service center for inspection. The wrench warning is set by the car manufacturer to remind owners to perform maintenance at specified mileage intervals. After maintenance is completed, the reminder light must be reset following a specific procedure to turn it off. It's also possible that the reminder wasn't reset during the last maintenance, requiring another reset. Here is some relevant information: 1. The wrench warning light on the dashboard illuminates every 5,000 kilometers or six months (whichever comes first). When the maintenance light comes on, you can go to a repair shop to change the engine oil and oil filter. After replacement, ask the technician to reset the maintenance light so it can remind you for the next scheduled maintenance. 2. The vehicle's maintenance cycle is preset during manufacturing, so the "small wrench" indicator will appear at regular mileage intervals to remind the driver to perform timely maintenance.

What are the causes of engine vibration?

Engine vibration can be caused by: 1. Damaged spark plugs, where the wear of the spark plug electrode gap leads to insufficient spark ignition, resulting in incomplete combustion of the air-fuel mixture; 2. Poor quality gasoline, which affects the atomization effect of the fuel injector, leading to incomplete combustion of the mixture in the cylinder; 3. Dirty throttle body or excessive carbon buildup in the fuel injector; 4. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor. An engine is a machine that converts other forms of energy into mechanical energy, first developed in the UK. It can refer to either the power generation device or the entire machine including the power unit. Types of engines include internal combustion engines, external combustion engines, and electric motors. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to generate power.

Is it okay to press the brake and clutch simultaneously?

It is generally not recommended to press the brake and clutch simultaneously. While doing so can prevent the engine from stalling to some extent, it may cause damage to the clutch, significantly reducing its lifespan over time. Here are some key points about brake and clutch operation: 1. Correct operation: Apply the brake first, then press the clutch when the vehicle speed decreases and is about to stop. 2. Incorrect operation: Pressing the clutch before braking increases the stopping distance and creates safety hazards, potentially leading to accidents. This is because the sudden disconnection of power output causes rapid engine RPM drop, reducing hydraulic system pressure and leaving wheels uncontrolled by the engine - creating significant safety risks. Emergency braking after clutch engagement essentially becomes neutral coasting, affecting braking distance. In congested traffic, using the half-clutch method not only wastes power but also negatively impacts vehicle longevity.

What to Do If the Vehicle Fails the Environmental Inspection?

It might be an issue with the catalytic converter. Here are some relevant details about the catalytic converter: 1. Principle of the Catalytic Converter: Vehicle exhaust contains many pollutants, with the most significant being carbon monoxide, hydrocarbons, and nitrogen oxides. Normally, after oxidation and reduction processes, the catalytic converter converts these into harmless carbon dioxide, nitrogen, and water, achieving purification. The catalytic converter is called a "three-way" converter because it contains three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name "three-way." 2. Solution: Before the inspection, drive on the highway for a while to bring the catalytic converter up to its operating temperature before testing. The most important point is not to turn off the engine before the inspection to keep the catalytic converter at a certain temperature. If it still fails, directly clean the catalytic converter and then retest to see if it passes.
