What does d-45t mean?

This is not d-45t, but D-4ST, where D-4 represents Toyota's proprietary direct injection technology, "S" stands for the enhanced version, and "T" indicates turbocharging. Below are the detailed specifications: Parameters: The D-4ST 2.0T+ engine delivers excellent power output and responsiveness across all RPM ranges, with a maximum power of 173Kw and a peak torque of 350Nm. Technologies employed: To achieve the four "+", it adopts the "four duals"—dual injection, dual scroll, dual cycle, dual VVT-i(W), along with water cooling technology and start-stop technology, among others.
In the automotive world, codes like D-45T typically refer to specific engine models. The 'D' stands for diesel engine, which is a crucial part, indicating it's more suited for long-distance driving and high torque output. The '45' most likely denotes displacement parameters, such as 4.5 liters or a related capacity, as numbers in vehicle codes are commonly used to identify engine size or power. The 'T' signifies turbocharging, which makes the engine accelerate more fiercely while being more fuel-efficient. I've seen similar structures used in SUVs and pickup trucks, such as the diesel version of the Ford F-150's engine; this design helps drivers understand the power characteristics, allowing them to avoid purchasing models unsuitable for daily needs by checking the code. A common issue is that the turbo system requires regular maintenance; otherwise, carbon buildup can easily affect performance. Maintenance is straightforward, but it's essential to change the oil on time.
