VVT-i Intelligent Variable Valve Timing System

VVT-i Toyota's Intelligent Variable Valve Timing System

The VVT-i system is an acronym for Toyota's Intelligent Variable Valve Timing System. The VYT-i system has been widely installed on the latest Toyota sedan engine. Toyota's VVT-i system continuously adjusts valve timing but does not adjust valve lift.

Its working principle is that when the engine is switched from low speed to high speed, the electronic computer automatically presses the oil against the small turbine in the intake camshaft drive gear. Thus, under the effect of pressure, the small turbine is relative to the gear. The shell rotates a certain angle so that the camshaft rotates forward or backward within a range of 60 degrees, thereby changing the timing of the intake valve opening and achieving the purpose of continuously adjusting the valve timing.

Cutting Machine Series

UTECH Cutting Machine Series include Plasma Cutting Machine, CO2 Metal and Nonmetal Laser Cutting Machine, Fiber Laser Cutting Machine. Mainly be used for cutting metal materials, such as stainless steel, carbon steel, aluminum, etc.

1) Plasma cutting machine include Portable type, Desktop type, Gantry type, you can choose any type you`d like. With CNC plasma cutting machines, businesses can greatly increase their capabilities, offering their clients and consumers high quality, high-end results. Known for precision, efficiency and versatility, CNC plasma cutting machines are an effective solution for manufacturing businesses, and with operations of all sizes and scopes. Here, you`ll learn more about CNC burn tables and CNC cutting machines.
2) Metal and nonmetal laser cutting machine can cut metal and nonmetal materials. Nowadays acrylic and steel is the most popular material in the advertise industry. Laser machines can do well performance according to it. For acrylic, customers normally need engrave and cut. The best option is co2 laser engraving cutting machine. There is different power(60w-300w) and working size(600*400mm-1500*3000mm) for meeting different requirements.
3) Fiber laser cutting machine, with 600*400mm, 1300*2500mm, 1500*3000mm working area. It is manufactured with aerospace standards and formed by 4300 tons press extrusion molding. After aging treatment, its strength can reach 6061 T6 which is the strongest strength of all gantries. Aviation aluminum has many advantages, such as good toughness, light weight, corrosion resistance, anti-oxidation, low density, and greatly increase the processing speed.

These kind of machine`s size and appearance can be customized.
