What is CVVT?

CVVT stands for Continuously Variable Valve Timing technology. Below is an introduction to CVVT: 1. CVVT is the abbreviation for Continuously Variable Valve Timing in English, which translates to continuous variable valve timing technology in Chinese. 2. The working principle of CVVT involves installing a CVVT assembly on the camshaft. When the engine shifts from low speed to high speed, the computer automatically applies oil pressure to a small turbine inside the camshaft drive gear. Under this pressure, the small turbine rotates a certain angle relative to the gear housing, causing the camshaft to rotate forward or backward within a 60-degree range. This changes the timing of the intake valve opening, achieving the goal of continuously adjusting valve timing. Therefore, under the influence of this structure, the engine can adjust the timing of valve opening and closing according to different road conditions. 3. The CVVT control device generally consists of components such as the oil control valve (OCV), CVVT drive assembly, crankshaft position sensor, camshaft position sensor, and engine control unit (ECU).

How to solve the ignition advance angle of cylinder 1 being less than 5?

You can use the method of a special distributor housing to adjust the ignition advance angle. The working principle of an automobile cylinder is to guide the piston to perform linear reciprocating motion within the cylinder. In the engine cylinder, air converts thermal energy into mechanical energy through expansion. In the compressor cylinder, gas is compressed by the piston to increase pressure, providing a power source.

How to Distinguish Intake and Exhaust Valve Springs?

Valve springs with five dots are for intake, while those with three dots are for exhaust. The rocker arm's larger wheel is for exhaust, and the smaller wheel is for intake. Longer valve springs are for intake, and shorter ones are for exhaust.

How to Deal with Normal Air Pressure Alarm?

It may be caused by a punctured tire, which triggers the tire pressure warning light. This situation usually involves a very slow air leak, and you can use a tire pressure gauge to measure it. When the air pressure drops below 1.8, you should immediately replace it with the spare tire and then drive to the nearest repair shop for fixing.

What is the method for valve adjustment?

According to the cylinder firing order, after determining that a certain cylinder's piston is at the top dead center of compression, the intake and exhaust valve clearances of this cylinder can be adjusted. After completing the adjustment, rotate the crankshaft and gradually adjust the valve clearances of the other cylinders using this method.

How to completely drain water from the cylinder?

If the engine has only mixed with water vapor and taken in water through the air filter, simply clean the water vapor from the air filter, throttle valve, and cylinder. If water enters the engine cylinder but does not affect normal driving, and there is a small amount of water in the engine oil or gasoline, it is necessary to replace the engine oil and clean the related engine components. If a large amount of water enters the engine cylinder, causing severe damage to engine components, a new engine must be replaced.
