What Causes Poor Acceleration in CVT?
2 Answers
Due to unstable oil pressure regulation, the valve body is damaged, resulting in poor acceleration. Here is the relevant introduction: CVT Introduction: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between CVT and geared transmissions is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving good fuel economy, power performance, and smooth driving, while also reducing emissions and costs. Working Principle: In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the small pulley, which drives the large pulley through the steel belt.
Recently, my car with a CVT transmission feels sluggish when accelerating, with a delayed response when pressing the throttle, especially noticeable during uphill climbs or overtaking. There could be several reasons, such as old or deteriorated transmission fluid reducing efficiency, or worn/damaged drive belts causing power loss. Faults in the ECU control system may also lead to delayed gear shifts and sluggish acceleration. Additionally, insufficient engine output—due to issues like poor fuel injection or clogged air intake—could be a factor. In such cases, regular maintenance and fluid checks are crucial. Neglecting these can result in poor fuel economy, safety risks, and a significantly degraded driving experience.
