Chrysler engines were equipped with VVT (for variable valve timing) starting in 2007. Here's how they work. There is a piece of modern technology for car engines called variable valve timing (VVT). VVT engines use cams on a camshaft to drive the flow of air into the intake and exhaust valves. with more precise handling of engine valves, some auto makers have shown that VVT can produce better fuel economy for vehicles Although it is possible for the engine to exist without this technology, you would see a great decrease in your fuel economy if this were to happen. This means fewer trips to the gas station and more money saved on fuel costs. This is how the engine can respond quickly to the demands of the driver. Since we won’t be seeing a camless engine in the average consumer’s hands anytime soon, we will have to continue adapting the age old camshaft to keep up with our ever-increasing horsepower needs. Maximum overlap usually occurs at high speeds, but if it is used at medium speeds with a light engine load, for instance during highway travel, engine efficiency increases. Required fields are marked *. If you’re interested, I recommend looking up each implementation to see how they work. That roaring sound you hear when you step on the gas pedal is the variable valve timing system hard at work to keep your engine running strong. NOTE- Honda's i-vtec tech is also same as VVT and VTVT. Many VVT implementations are very similar and generally pretty good. Regardless of industry, product, or machine design, one thing remains constant – the need for safety. For instance, a sedan would probably run the most efficiently at medium engine speeds, while a sports car might run more efficiently at a higher RPM. of torque at 2,800 rpm. Adding multiple valves per cylinder certainly made a difference, but efficient valve timing is tied to a specific engine speed. The way these processes work can vary slightly in each type of car. At times when engine performance is not needed, you can still maintain great efficiency in the engine. Variable valve timing technology does not get enough credit for its eco-friendly nature. Introducing VVT to a combustion engine allows for more precise control of engine output and can greatly increase fuel economy You may think that it is counterproductive to have an overlap in the exhaust and intake valves because that means exhaust … Some models also adjust the height that the valves open, giving more area for air to flow in and out of the cylinder. Variable valve timing and lift can dramatically change an engine's power output and efficiency. We conclude that VVT has much potential. If you have variable valve timing in your engine, then it will help keep it strong for as long as possible. As the engine speed increases, there is less time for exhaust and intake air to enter and leave the cylinder since the valve isn’t open as long. 3.6 Liter VVT.
