Nissan's VTEC?

Being a honda owner I know honda went from many variations from 3-4 valves per a cylinder to a 2nd cam lobe to different lift to having it on the intake as well as exhaust. im sure i left some out.

I was reading the current 1.6 versa engine and others used a setup similar to bmw. Its a egg shape lobe between the cam and lifter and its rotated in and out to vary the lift and the cam has something to twist it to advance or retard it.

Seems like a lot to have on a cheap car like ours and the hp and tq are lower than the Fit .

Not sure I understand the dual injector thing either with direct and port injection. I thought direct was the new thing an could eliminate the need for spark plugs and allow use of flex fuel.

On the earlier '11 I have the intake has a VCT setup on the intake that moves the entire cam retard or advance, thinking it's mainly to change overlap to not need an EGR valve system.

Direct injection blasts the cylinder with way more pressure than normal injection, like 600-800 psi vs. the 50 or so of port. And directly inside the cylinder, it then allows a whopping increase in compression to make more power. You still need plugs to light it off though, unless a diesel, which never used plugs anyway.

Yeah I feel like Nissan put all their VVT and related magic into making a long flat curve of usable torque instead of worrying about the peaks. No doubt honda simply builds a better motor and gets more out of less, thats a fact, but the Nissan 1.6 isn't too terribly far behind the fit's engine.

I do like the lines of those Fits but just never could come around to paying the prices Honda wants for their cars. I had plenty of their bikes to know how they go about a lot of things.

I too looked at the Fit. You just as well toss in an extra grand and get the entry level civic.

DE engine updates (2006-)[edit]

Changes include:
neutral idle control achieved through the coordinated control of the engine
in tandem with the XTRONIC CVT
introduction of alternator regenerative control mechanism
Reduction of engine friction by machining the cam shaft to a crowning
mirror-like finish and application of a fluorine coating to the chain guide
Delayed valve closure timing of the intake, achieved through the increased
conversion angle of C-VTC and superior timing management, thus reducing
pumping loss when idling
Lower idling speed

The improved HR15DE engines were first used in Nissan Cube, Nissan Cube
Cubic, Nissan Note, Nissan Tiida, Nissan Tiida Latio and Nissan Wingroad
sold since December 25, 2006.[5][6]
