Why is 92 octane gasoline recommended for a compression ratio of 13?

This situation mainly occurs in Mazda engines, which have a compression ratio of 13 but can use 92 octane gasoline. This is primarily because the engine has been structurally designed specifically for lower octane gasoline, and engines without such design cannot adopt this approach. More reasons are explained as follows: 1. Reason one: To reduce engine knocking, this engine features a specially designed exhaust manifold. The long exhaust manifold design is used to minimize the impact of exhaust heat on the combustion chamber temperature. 2. Reason two: The engine also reduces the temperature of the piston and combustion chamber by installing an oil spray nozzle under the piston, preventing knocking caused by high temperatures and the relatively poor anti-knock properties of 92 octane gasoline. 3. Reason three: This mainly applies to Mazda engines with special designs. For ordinary engines with a compression ratio of 13, 95 octane gasoline should be used.

What is the intake manifold pressure?

Intake manifold pressure is normally between 40 and 80 kPa. When the engine is running, during the intake stroke, the downward movement of the piston creates a suction effect, causing the intake manifold pressure to be lower than atmospheric pressure. The intake manifold is usually made of plastic. Since PA has lower thermal conductivity than aluminum, the fuel injectors and incoming air temperature are lower. The main factors affecting intake manifold pressure are as follows: 1. Throttle opening: The smaller the throttle opening, the greater the suction effect created by the piston during intake, resulting in higher vacuum suction in the intake manifold, meaning lower intake manifold pressure. 2. Sealing performance: This includes the sealing of the intake manifold and cylinders. Better sealing performance leads to a greater suction effect created by the piston during intake, resulting in higher vacuum suction in the intake manifold, meaning lower intake manifold pressure.

What Does the Left Foot Control in a Manual Transmission?

Left foot controls the clutch pedal. The clutch pedal has functions and working principles. Functions of the clutch pedal: Through proper operation by the driver, it achieves the engagement and disengagement between the front and rear parts of the clutch (engine and transmission). It indirectly enables: starting, gear shifting, reversing, and braking. Working principle: The clutch consists of friction plates, spring plates, pressure plates, and power output shafts, arranged between the engine and the gearbox. It transmits the torque stored on the engine flywheel to the transmission, ensuring that the vehicle delivers appropriate driving force and torque to the drive wheels under different driving conditions, falling under the category of the powertrain. During semi-engagement, the clutch allows a speed difference between the power input end and the power output end, meaning it transmits the appropriate amount of power through this speed difference.

How to Fold the Rearview Mirrors of Ora Black Cat?

Ora Black Cat's rearview mirrors can only be folded manually. The methods are as follows: 1. Hold the base of the rearview mirror with one hand and push the mirror backward with the other hand. 2. Fold the manual rearview mirror by pulling it backward with force, but avoid using excessive force. Lift it slightly upward. If you find it difficult to do it yourself, it is recommended to have someone with experience handle it to avoid unnecessary damage. 3. Adjust the left rearview mirror: When adjusting the left rearview mirror vertically, position the distant horizon in the center. For horizontal adjustment, adjust until the car body occupies one-fourth of the mirror's surface. 4. The central rearview mirror can effectively control the distance. Adjust the left and right positions so that the left edge of the mirror just aligns with your right ear in the reflection.

Can Alcohol Be Placed in the Car?

It can be placed, but medical alcohol has a high concentration and is not recommended to be kept inside the car. The following items should not be placed in the car under high temperatures: Mobile phones and chargers: Chargers and mobile phones pose a risk of explosion under high temperatures, presenting a hidden danger. Lighters: Do not casually leave lighters in the car. If you have a lighter, place it in a shaded area to avoid explosions. Reading glasses and magnifying glasses: Reading glasses are convex lenses, no different from magnifying glasses. Sunlight refracted through reading glasses can form a focal point, which may lightly damage the car's interior or, in severe cases, cause a fire.

Will Insurance Cover a Smashed Windshield?

Only if you have purchased insurance, the insurance will cover a smashed windshield. Auto insurance can be divided into compulsory traffic liability insurance, vehicle damage insurance, and third-party liability insurance. Compulsory Traffic Liability Insurance: Compulsory traffic liability insurance is the first mandatory insurance system implemented by national law in China. The 'Regulations on Compulsory Traffic Accident Liability Insurance for Motor Vehicles' [hereinafter referred to as the 'Regulations'] stipulate that compulsory traffic liability insurance is a mandatory liability insurance where the insurance company compensates for personal injury, death, or property damage caused by the insured motor vehicle in a road traffic accident within the liability limits. Vehicle Damage Insurance: Vehicle damage insurance refers to the insurance company compensating for the loss of the insured vehicle caused by natural disasters (excluding earthquakes) or accidents within the scope of insurance liability, according to the provisions of the insurance contract.
