What does continuously variable transmission mean?

Continuously variable transmission (CVT) is a type of automatic transmission system that can continuously obtain any transmission ratio within the speed range. Below is relevant information about CVT: 1. Classification: CVT allows for optimal matching between the drivetrain and engine conditions. Common types of CVTs include hydro-mechanical CVT, metal belt CVT (VDT-CVT), and variable-angle CVT. To achieve continuous variation, three transmission methods can be employed: hydraulic transmission, electric transmission, and mechanical transmission. 2. Historical background: The primary structural difference between CVT and conventional hydraulic automatic transmissions lies in their design. The latter consists of a hydraulically controlled gear-shifting system with fixed gears, achieving stepless shifting only between two gears. In contrast, a CVT comprises two variable-diameter pulleys and a belt, making it simpler in structure and more compact than traditional automatic transmissions.

What Do the Gears in a Car Mean?

In an automatic transmission car, the P on the gear stands for Park, R stands for Reverse, N stands for Neutral, and D stands for Drive. Regarding speed: First gear corresponds to a speed of 0-5 km/h. Second gear corresponds to a speed of 5-20 km/h, third gear corresponds to 20-40 km/h, fourth gear corresponds to 40-60 km/h, and fifth gear corresponds to 60-100 km/h. Shifting timing: Generally, the shifting timing for most cars is when the engine speed reaches 2000 r/min, and it should not exceed 2500 r/min. For some high-displacement, high-power engines, shifting can be done around 3000 r/min.

What size rear axle is a 4.875 ratio?

4.875 ratio corresponds to a 158 rear axle. Here are the details: 1. Content: 4.875 is a low-speed axle. The rear axle ratio is an important engine parameter, referring to the gear ratio of the main reducer in the vehicle's drive axle. There is a set of gears in the rear axle behind the driveshaft that serves to reduce speed and increase torque. The vehicle's transmission ratio, also called the speed ratio, is the ratio of rotational speeds between the front and rear transmission mechanisms in the vehicle's drivetrain. The rear axle refers to the assembly that transmits power to the rear drive wheels, supporting the wheels and connecting the rear wheel assemblies. 2. Advantages: A smaller rear axle ratio provides higher speed and lower fuel consumption. The 4.875 ratio is suitable for heavy loads and offers good power performance.

Is 100,000 kilometers a lot for a car?

100,000 kilometers is considered mid-life for a car. However, after reaching this mileage, many minor issues often start to appear, making regular maintenance essential. Overview of car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain components of a vehicle, also known as vehicle servicing. Currently, car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other related systems. The purpose of car maintenance: The goal of car maintenance is to keep the vehicle clean and in good technical condition, eliminate potential hazards, prevent malfunctions, slow down the deterioration process, and extend the vehicle's service life.

Does Engine Oil Decrease Over Time?

Engine oil does decrease over time. Here are the specific reasons why engine oil decreases with use: 1. Combustion Consumption: The piston, piston rings, and cylinder liner have the function of sealing high-temperature combustion gases and transmitting engine combustion power, so they must be well lubricated. The crankshaft splashes oil to various parts of the engine, and the piston rings scrape off the oil adhering to the cylinder liner each time they move downward. However, some oil still remains on the cylinder liner and participates in combustion inside the cylinder, leading to consumption. This is the primary reason for engine oil consumption. 2. Power Stroke: To enhance lubrication between the cylinder liner and piston and reduce wear, the engine has patterns on the cylinder wall surface designed to store oil. These patterns can hold more oil, resulting in higher oil consumption during each power stroke.

Will 3M Adhesive Damage Genuine Leather on the Dashboard?

3M adhesive can damage genuine leather on the dashboard. Here are the details: 1. Content: Any adhesive should be kept separate from leather, otherwise the leather's shine will disappear, the surface will be damaged, and it will become rough. 2. Treatment methods: You can wipe it with a cloth soaked in vinegar or alcohol. Use the hot-dry method, or wipe with a cleaner or sneaker stain remover. First, scrape off the adhesive on the surface and treat it with adhesive remover. Essential balm, rubber solvent, alcohol, or gasoline can effectively remove surface adhesive. Use asphalt cleaner. Blow the 3M tape with a hairdryer on high heat to soften it, then slowly peel it off. For residual adhesive, wipe with diesel fuel, and after some time, wipe with a towel.

What is Honda Maintenance Additive?

Honda maintenance additive is an engine oil additive that is directly added into the engine to prevent oil deposits. More knowledge about engine oil additives is as follows: 1. Introduction: Engine Protector, also known as engine oil additive, is a professional additive specifically designed for engines. Engine Protector can effectively lubricate the engine, enhance oil quality and durability, thereby achieving the purpose of protecting the engine. The additive content in lubricating oil is based on meeting the minimum requirements of API (the best mass production cost-performance ratio), not the best effect as the design standard. The highest-grade lubricating oil cannot be directly used in off-road rallies or F1 races. 2. Principle: By using engine oil additives, the performance of the engine oil is improved to the top level, and expensive components such as graphene and organic molybdenum, which are too expensive to be added in lubricating oil, are also added.
