VTEC Variable Valve Timing and Lift Electronic Control System

The VTEC system name is a variable valve timing and lift electronic control system. It is a proprietary technology of Honda. It can appropriately adjust the valve timing and valve lift as the engine speed, load, water temperature, and other operating parameters change. The engine can achieve maximum efficiency at both high and low speeds. In the VTEC system, there are three cam surfaces on the intake camshaft, respectively, which jacks the three rocker arms on the rocker arm shaft respectively. When the engine is in low speed or low load, there is no connection between the three rocker arms. The right and left rocker arms actuate the two intake valves, respectively, so that the two have different timings and lifts to form the effect of squeezing air. At this time, the high-speed rocker in the middle does not actuate the valve, but does no effective motion on the rocker shaft. Tiexue.net/ When the speed is increasing, the engine's sensors send the monitored load, speed, speed, and water temperature to the computer. The computer analyzes and processes the information. When it is necessary to change to the high speed mode, the computer sends a signal to open the VTEC solenoid valve, so that the pressurizing oil enters the top piston in the rocker shaft, so that the three rocker arms are connected into one, so that both valves operate in the high speed mode. When the engine speed decreases and the valve timing needs to be changed again, the computer sends out a signal again, opens the pressure of the VTEC solenoid valve, releases the pressure oil, and the valve returns to the low speed operation mode again.
