The Advantages of Variable Valve Timing Engine


There is a piece of modern technology for car engines called variable valve timing. It helps to boost the efficiency and overall performance of your engine. How does it do this? Well, the variable valve timing manages the opening and closing of the air intake valve and the exhaust valve. These are the valves responsible for allowing outside air to flow inside and to replace exhaust emissions; respectively. The timing and speed at which these valves open are crucial for the engine to perform well. 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.

The variable valve timing system is comprised of various mechanical and hydraulic components to create the lift effect for the valves. This is how the engine can respond quickly to the demands of the driver. At times when engine performance is not needed, you can still maintain great efficiency in the engine. Today, you will find the top three Japanese car manufacturers using this technology, including Toyota, Mitsubishi, and Honda.

The Top 4 Advantages

Everyone wants to have a high performing engine. Out of all the components and machinery in a vehicle, the engine is the most important. If you can get it to do its job well, you can ensure that your vehicle stays healthy for a good long time. Meanwhile, you will enjoy many advantages as the driver of the vehicle which has this technology. To sum up what those advantages are, below are the top 4 advantages of having a variable valve timing engine.

Better RPM Strength – The main advantage of having a variable valve timing technology is the increase it will provide in your engine’s revolutions per minute. When you step on the gas pedal to accelerate the vehicle faster, it will require more RPMS to sustain this demand. The variable valve timing has a lot to do with making this happen. 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.

Better Fuel Economy – Engine efficiency has a lot to do with the timing of the exhaust valve and intake valve. If these valves can be managed and timed properly from the variable valve timing technology, then the engine will be able to produce the same power without needing so much fuel. If your engine doesn’t require as much fuel, then you will see your gas mileage increase. This means fewer trips to the gas station and more money saved on fuel costs.

Lower Carbon Emissions – Any time your engine provides a better fuel economy, you will see reduced carbon emissions too. Variable valve timing technology does not get enough credit for its eco-friendly nature. If RPM strength and better fuel economy weren’t enough to convince you that this technology is beneficial, then hopefully its ability to reduce carbon emissions will change your mind. If you live in a state which has required emissions testing, then this technology will increase your chances of helping you pass the test.

Increased Engine Lifespan – If you continue to maintain an efficient and high performing engine, then you can expect to get a great number of years out of it. A lot of people will wait until their engines go bad before they decide to replace their vehicle. If you have variable valve timing in your engine, then it will help keep it strong for as long as possible. Of course, there are other factors involved in keeping an engine healthy too. Make sure you regularly get oil changes and use the right kind of fuel.
