The Impact of Control Valve Lag on Injection Performance

The Effect of Control Valve Lag on Injection Function 

That's right — so much has to come together and work just right for our cars to run smoothly. The control valve is one of those key parts, and it can have a serious impact on the way that the fuel injection system performs. So today we are going to discuss control valve lag, and how it can actually be one of the more impact elements for how our cars perform. 

Control Valve Lag, and why it matters to fuel injection accuracy 

Give—or try to give—an image: It is a very hot day and you are at the Water Paradise. Your standing in line, waiting for the huge slide and anxious to take it down for a refreshing break. However, all of a sudden, the slide jams and the water stops running. You need to wait until the water begins running through it again before you can eventually take the plunge. It's somewhat akin to resting when the injector control valve lags in an automobile fuel injection system. 

Such as a gatekeeper, the control valve makes sure that only the right quantity of fuel is entering into the engine at correct moments. However, occasionally there can be a delay with how fast the valve opens and closes. And this delay, or lag, messes up the timing of when the characteristic fuel needs to go into the engine and hinders how well the car runs. 

If the control valve is delayed, it will affect the performance of the engine 

The engine may idle poorly or even die with control valve lag. If we understand that its a pool of water this is easy for us to conceptualize, the engine receives the cylinder into which fuel and air enter when it begins to intake, or "open", as our hole lets some (or all) of the water in (our "port open"), but remember now that with no pressure built up first there will still not be enough force behind it so our port is working like a straw if at all presently. This makes the car bog down with reduced acceleration and/or less power, thus higher emissions. 

How control valve lag is related to fuel efficiency 

Not only does delay in the control valve influence the efficiency of engine performance, but also fuel consumption. If the valve fails to open and close at the correct times, this can result in an engine using more fuel than it truly requires. That means more stop at the pump fill ups which can get expensive and be harmful to the environment. 

Mitigating the Influence of Control Valve Lag on Injection Performance 

Now these are just a few things that we can do to reduce the negative effects of the control valve injector lag on our cars. One tactic is to maintain and clean the control valve on a regular basis so that it works effectively. One trick is often the use of high-grade fuel and added muscle to get a good shot at improving fuel injection. 

Control valve response time is a critical in dictating engine responsiveness 

In the end, making sure that the control valve responds quickly and accurately to the engine is what keeps our cars humming along. This also, in turn, implies that the valve has to open and close at very precise times to make sure that everything is working as it should. Now that we know a little bit about fuel metering control valve lag and how it can affect our automobiles, we can avoid its common causes and keep our cars is top operating conditions. 

In the end, control valve lag may appear to be small in the overall scheme of things but it has a huge effect on how well our cars function. Now we are just aware of the impact that control lag in this case leads to poor fuel injection accuracy which directly impacts engine power, efficiency and overall immediate performance all around. And since small things do count when it comes to keeping our vehicles in good working order. Derun Mechanical helps keep our cars purring like kittens!
