What kind of engine does yaris use?

Yaris yaris is equipped with the same 16 dual VVT-I engines as Corolla, which can fully release energy and effectively reduce fuel consumption.

Introduction to VVT

VVT is an English "variable"? Valve? The abbreviation of "timing" means "variable valve timing" in Chinese. Because it is controlled by electronic control unit (ECU), Toyota has a nice Chinese name "Intelligent Variable Valve Timing System". The system mainly controls the camshaft of the intake valve, and has a small tail "I", which is the English code for "intake". These are the literal meanings of "vvt-I". ?

With the development of science and technology, VVT-i engine has new technology, and now it is divided into VVT-i and dual VVT-i?

Single VVT-i is unilaterally controlled by variable valves, and there is a problem in the field when the engine rotates. The rotation area is only controlled unilaterally, and there may be dislocation of the rotation area. Therefore, it is very important to achieve the balance of intake and exhaust at this time, so that the rotation range of the engine can achieve the balance of intake and exhaust under any circumstances. ?

Dual VVT-i means to control the intake system and exhaust system of the engine respectively. When accelerating rapidly, VVT-i controlling the intake will advance the intake time and improve the valve lift, while VVT-i controlling the exhaust will delay the exhaust time, just like a small turbocharger, which can effectively improve the engine power. At the same time, due to the increase of air intake, gasoline burns more fully, achieving the goal of low emission. ?

The new 4-cylinder inline overhead dual camshaft EFI 16-valve ZR engine in yaris, yaris adopts dual VVT-i technology. Dual VVT-i means to control the intake system and exhaust system of the engine respectively. When accelerating rapidly, controlling the intake VVT-i will advance the intake time and improve the valve lift, and controlling the exhaust VVT-i will delay the exhaust time, thus effectively improving the engine power. At the same time, due to the increase of air intake, gasoline burns more fully, achieving the goal of low emission. In addition, the optimized rigidity of engine components achieves excellent low vibration and quietness.
