Is Honda Earth Dream Engine Really Bad? Will there really be as much carbon deposit as they say? If it is not good, then why is Honda equipped with so many models?

VTEC system actually improves the intake efficiency of the engine by switching the camshaft with a longer stroke. At low speed, the small angle cam pushes one valve to open, and at high speed, it opens two valves to enhance air intake.

Honda's i-VTEC variable valve lift system realizes the switching of high and low angle camshafts by separating and combining three rocker arms, thus changing the valve lift.

In-cylinder direct injection technology is added, which is also a highlight of this engine. Using in-cylinder direct injection technology can control fuel injection more accurately and make the mixture burn more fully, thus reducing fuel consumption and improving engine power performance.

Honda released a new generation of powertrain "Earth Dream Technology", which is a perfect combination of low fuel consumption, high power and driving pleasure. Earth Dream Technology is a brand-new technology aimed at protecting the earth's environment and ensuring driving pleasure, which will be gradually expanded and introduced into Honda products in the future.
