How does the camshaft work in a Honda VTEC?

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.

What should the compression be on a Honda ATV?

You will need to check your repair manual for your particular model for the correct compression specifications. See note below. Usually, an engine will run OK if it has at least 100 PSI of compression. Most engines will have somewhere between 100-250 and some as high as 300 PSI, depending on the engine.

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.

How do you test engine compression in a Honda?

OK, when you’re ready, have a helper crank up your Honda as you observe the needle on the compression tester’s gauge. Once the needle on the gauge stops climbing, have him or her stop cranking the engine.

Can a Honda 2.2L engine have no compression?

OK, having covered the most common scenarios of low compression and no compression, let’s get testing to see if this is the case on your 2.2L, 2.3L Honda. Let’s jump right into the engine compression test. Before you start, let me just say that you’ll be working around a cranking engine, so you have to be careful and stay alert at all times.

What kind of compression ratio does a Honda K24A have?

The compression ratio is 9.7:1. The engine also has a 16-valve DOHC i-VTEC head. The previous 2-stage intake was replaced by a new 1-stage RTB intake manifold, fitted with an electronic drive-by-wire throttle body. The exhaust system has a high-density catalytic converter that helps the engine meet emission standards.
