4 Advantages of Variable Valve Timing (VVT) Engines
Automotive engines have a new technology called variable valve timing (VVT). Using this technology improves the engine’s efficiency and overall performance. Keep reading to find out how variable valve timing works and its main benefits.
How variable valve timing works
Variable valve timing controls the opening and closing of intake and exhaust valves. These valves are responsible for allowing the inflow of fresh air and the exchange of exhaust gases. The timing and speed at which these valves open is critical to engine performance. The engine will function without this technology, but will consume significantly less fuel.
The variable valve timing system is made up of various mechanical and hydraulic components that create the valve lift effect. This allows the engine to respond quickly to driver demands. High engine efficiency can be maintained even during periods when engine power is not required. Currently, the big three Japanese automakers, including Honda, Toyota, and Nissan, use this technology. How these processes work may vary slightly from car to car.
For example, the variable valve timing system in Honda engines uses camshafts to lower RPMs. To make this possible, a computer monitors inside the engine to calculate every state of the vehicle. It checks engine RPMs and accelerator pedal position to determine if a high-performance camshaft needs replacing.
The Four Most Important Benefits Everyone wants a high-performance engine, whether they want to admit it or not. Of all the components and machines in a car, the engine is the most important.
If you can keep it functioning properly, your car will stay in good condition for a long time. In addition, drivers of vehicles equipped with VVT enjoy many benefits. To summarise these benefits, here are the top 4 advantages of a variable valve timing engine:
1) Higher Speed
The primary benefit of variable valve timing technology is that it increases the number of revolutions per minute of the engine. When you step on the accelerator and accelerate your vehicle, the engine RPM increases, which generally translates to more power (to some extent).
Variable valve timing goes a long way in making this possible. That “boom” sound you hear when you step on the accelerator is the variable valve timing mechanism working hard to keep the engine revving.
2) Reduced fuel consumption
Engine efficiency depends heavily on the control of the exhaust and intake valves. If these valves can be controlled properly and with variable valve timing technology, the engine can produce the same power without using as much fuel.
If the engine doesn’t need as much fuel, it can reduce fuel consumption. This means fewer trips to the gas station and more savings on fuel costs.
3) Reduced CO2 emissions
Every time an engine becomes more fuel efficient, it also reduces CO2 emissions. Variable valve timing technology is under-recognized for its environmental friendliness.
If the faster speeds and lower fuel consumption didn’t convince you of the technology’s effectiveness, we hope its ability to reduce CO2 emissions will change your mind. If you live in a state that requires emissions testing, this technology will increase your chances of passing the test.
4) Longer Engine Life
If you maintain an efficient and powerful engine, you can expect it to last for many years. Many people wait until their engine breaks down before deciding to replace their car. Having variable valve timing on your engine helps keep it running as efficiently as possible for as long as possible.
