Toyota's D4ST refers to the use of a four-stroke dual-injection turbocharged engine. The 'D' stands for the dual-injection system, 'T' represents turbocharging, and '4' indicates four-stroke. The dual-injection system is also known as a hybrid injection system, meaning the engine has two sets of injection systems: direct fuel injection and intake port injection. Under different operating conditions, the engine adopts different injection methods. Engines equipped with the dual-injection system are more powerful and fuel-efficient. Many Toyota models feature the D4ST badge at the rear. Toyota is an automobile manufacturing company founded by Kiichiro Toyoda in September 1933. Its passenger car brands mainly include the core brand Toyota and the luxury brand Lexus.

How often should the transmission fluid be changed for the Tiggo 3?

According to the manufacturer's specifications for the Tiggo 3, the transmission fluid should be changed every 15,000 kilometers or every 18 months. Transmission fluid is a lubricant that maintains the cleanliness of the gear system, ensuring the proper functioning of the transmission and extending the lifespan of the transmission components. Below are two methods for changing the transmission fluid: 1. The traditional gravity method involves draining the fluid, similar to changing engine oil, by loosening the drain plug of the transmission to release the old fluid and then refilling with new fluid. 2. Using a transmission fluid exchange machine to replace the automatic transmission fluid, which primarily utilizes the machine's pressure to dynamically replace the fluid in the torque converter's lubrication lines and cooling lines.
