What is vtech

If you're a car enthusiast, you've probably heard the term "VTEC" before, but you might not know what it means. If you don't, here's an explainer. VTEC is a type of variable valve-timing system developed and used by Honda. Like most other variable-valve timing systems , VTEC varies oil pressure to shift between different cam profiles.

At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower. But the way VTEC goes about switching cam profiles is totally distinct. Most variable valve-timing systems use increased oil pressure to shift the timing of the camshaft, opening the valves earlier; VTEC uses an entirely different set of cams at high RPMs.

Larger lobes will open the valves further than smaller ones. If you are interested in knowing about the reasons why your check engine light is on , you can check the guide we created. In an engine, the camshaft is a long rod that normally sits above the cylinder and the piston, and that operates the valves which plug up both an intake channel and an exhaust channel.

Your spark plug discharges, allowing the fuel inside to combust, and another rotation opens the exhaust channel as the intake channel is closed, pushing out the exhaust gasses. During this process, the pistons move up and down in the cylinders. Quite a few variables control how an engine produces the power needed to make a car move. The process of opening and closing the valves that we just described works well at low revolutions per minute rpm , but the valves open and close so quickly as the engine builds up speed that performance ultimately starts suffering.

We suggest you watch it before reading the rest, because it will help our explanation make a whole lot more sense. The caller was the same — Michael Jordan — and the number was the same — I screen all my calls through my answering machine and did not pick up.

This is the second call in a month from the same caller. When I called my bank to say this was a fraudulent charge made without my consent, they canceled it, but sent me a new credit … Read more ».

Maybe you used to scam cuz you know it so well. Do you feel smarter now.

Go make Merika great again. I just go this call from a Jeffrey saying I would be charged He said he had to show my on my computer how to cancel it out so my bank account would not be charged.

I said if they sent the product they could cancel it out from where they were and refund me without any information or me going on my computer with them to cancel it out.

Thank you for the above information — I just received a call with the call back number Name to call was Sam Smith. Just received an automated call from VTech Solutions and a Mr. If we want to cancel we should call Totally bogus! The voice was computer animated I pretty much know it was a scam and oh well so it is.

I was not home but it was on my answering machine, the number they called from is Account manager was a Sam Jorden, I thought it might be a scam as I do not have anti virus with them.

Martin security manager Cancel charge within 48 hours. Ignored call. Here is another phone number you can add to the list for V-Tech Solutions Donald Richard, Customer Relationship Manager was giving us 24 hours to cancel the subscription we had not purchased in the first place. I just received a Vtech call from Washington DC.
