4 Interesting Facts about Dual VVT-i Engine. The development of increasingly advanced technology makes the car's performance more capable both in terms of power and fuel efficiency. Fuel efficiency is crucial because the need for saving gasoline consumption is one of the main needs of vehicle users. Toyota calls it an improved Vios, which gets a much more refined and fuel efficient powertrain with a new 1.5-litre dual VVT-i engine and CVT (continuously variable transmission) with a 7-speed Sport Sequential Shiftmatic mode. The new 1.5-litre dual VVT-i engine produces 107ps at 6,000rpm and 140Nm of torque at 4,200rpm. It is a 24-valve DOHC engine with two belt-driven camshafts and a dual-stage intake manifold. 1JZ-GE 1996 Toyota Mark II Grande G (X90) shown with a 1JZ-GE The adoption of VVTi, a much higher efficiency single turbocharger than the twins as well as different manifold and exhaust ports were responsible for most of the 50% torque increase at Mengenal Teknologi Mesin Toyota VVT-i dan Dual VVT-i. Liputan6.com, Jakarta - Sejak 2004, mobil Toyota yang dipasarkan di Indonesia sudah menggunakan teknologi VVT-i. Sejatinya, teknologi merupakan pengembangan mesin variable valve timing (VVT), yang sudah digunakan oleh raksasa asal Jepang tersebut sejak 1991. Meanwhile, for dual VVT-i car engines, spark plugs with a size of 14 mm are usually used. In addition, spark plugs for dual VVT-i car engines usually use iridium spark plugs. This spark plug has the characteristic that the center electrode is smaller than the spark plug for VVT-i car engines. Here you can see clearly the spark plugs on a dual On VVT engines, valve timing or valve overlap occurs. Valve overlap is the period during the valve timing where both the intake and exhaust valves are open. Occurring towards the end of the exhaust stroke, the intake valves are opened just before all the exhaust gases are released, providing more time for the intake air to enter the engine. The difference between the 1GR VVT-I actuators of year models 2003-2004, and 2005-2015, for the SINGLE VVT-I 1GR (NOT the dual VVT-I 1GR) is their pick-up design. Visually obvious in the two pictures. The first picture is what the intake cam gears look like, on the '05 Tacoma to '15 Tacoma. The sensor which reads it is different from the sensor Male.

Wouldnt be worth your time money etc. While it might bolt up 90% of the way that extra 10% is going to chew 90% of your time and money. All for really not much. Stick with a single VVTi or if you are going to do a swap do a better swap. Perbedaanya Dengan Dual VVT-I. Pada dasarnya, konsep antara VVT-I dan Dual VVT-I itu sama, namun VVT-I itu hanya digunakan pada mesin dengan camshaft tunggal (SOHC) atau kalau pada mesin DOHC, maka hanya intake camshaft yang memiliki mekanisme VVT-I, sementara exhaust camshaft masih konvenional. Rebuilding a single vvt-i to a dual vvt-i would not be worth the effort. Just buy a already built dual vvt-i but even then the systems in the vehicle probably wouldn't work so you would have to go through every sensor and module and update it if there was a difference. At that point, just trade in the 2007 for an 2010+ and you would save money. Single VVT: Continuously varies the timing of your intake camshaft (only) Dual VVT: Varies the timing of the intake camshaft and the exhaust camshaft. Essentially, the dual VVT system creates a solution that helps the engine breathe more efficiently. By adjusting the timing of the valves, you can generate more power, better fuel efficiency, and Mengingat inovasi mesin Dual VVT-i memiliki banyak sekali keunggulan atau kelebihan, bila dibandingkan dengan kekurangannya. Teknologi generasi penerus dari VVT-i tersebut diklaim lebih bertenaga, namun hemat bahan bakar. I checked all "gen 2" 2tr-fe equipped Toyota products aka the dual vvti 2tr-fes are equipped with immobilizers. and yes, I did just get it running unfortunately during the test drive the radiator fan hit the radiator, it dumped all the coolant and the engine seized. when it cooled down it would turn over but it has zero compression. it was The new Toyota Yaris and Vios are now available in the Philippines. Toyota Motor Philippines held the launch for the two cars in Bonifacio Global City earlier today, providing would-be customers with more efficient engines and a few minor aesthetic upgrades. Both models now come with Toyota's NR-series Dual VVT-i engines. In 2015, the 2TR-FE was upgraded, which resulted in the introduction of the Dual VVT-i variable valve timing system (before that, the phase shifters were only at the intake) and the compression ratio was increased from 9.6:1 to 10.2:1. The simple design and time-tested components make the 2TR-FE engine one of the most reliable Toyota engine. x8wOkn6.
