What is single cam VTEC?
SOHC – Single Over Head Cam Shaft a design in which one camshaft is placed within the cylinder head. VTEC stands for Variable Valve Timing and Lift Electronic Control and represents a variable valve control system developed by Japanese Honda for its gasoline engines.
How does the camshaft work in a Honda VTEC?
In the traditional engine, the camshaft controls valve opening and closing, and its lobes are all the same size. In Honda’s VTEC engine, as you saw in the video, the camshaft has two different types of lobe sizes: Two standard-sized outer lobes and a larger center lobe.
When does the VTEC go on in a Honda?
It’s active when the engine is operating relatively high in the rev range, and you rarely get there in normal driving conditions, especially if your car has an automatic transmission. But, if you’re the shift-your-own-gears type and you like twisty roads, VTEC makes a noticeable difference.
Which is better a VTEC engine or a regular engine?
However, there are legitimate reasons for it. Hondas with VTEC engines are much more efficient across a wider RPM range than most other vehicles, and arguably are much more fun to drive for those of us who value pick up and go. But for a large majority of us, you’ll likely not “ride VTEC” in everyday driving.
Where is the camshaft located in a Honda engine?
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. One rotation opens the intake channel, allowing fuel and air into your engine’s cylinders.
Do you need dual cams to run VTEC?
You do not need a dual cam setup to run vtec. I believe your civic has a stock d series engine which is a single cam most, likely a d16 (if you have a d15 it is more complicated). The difference is with SOHC there is a common camshaft for both intake and exhaust valves. where as with DOHC there are separate cams.
How does the Honda VTEC engine timing system work?
A third option is to change the cam timing profile, of which Honda VTEC was the first successful commercial design for altering the profile in real-time. The VTEC system provides the engine with valve timing optimized for both low and high RPM operations.
What’s the difference between SOHC and VTEC in Honda Civic?
The difference is with SOHC there is a common camshaft for both intake and exhaust valves. where as with DOHC there are separate cams. VTEC is a variable valve timing system which is engaged at higher RMPs so you get better performance when you need it and don’t burn extra gas and risk wear on your engine riding around at lower RPMs.
Can a Honda Civic 150i be a VTEC?
Ok so my ’97 Civic 150i is running a little to slow for my liking. I want it to be able to hang with a 2.0. The first thing that comes to mind is swapping the motor out to make it the same as a VTEC under the hood. What I want to know is, do I need to get the entire engine, motor. . . I’m really clueless?
