What does i-VTEC DOHC mean?
i-VTEC stands for Intelligent Variable Valve Timing and Lift Electronic Control, a system created by Honda to improve fuel consumption of Honda vehicles. The VTEC system uses two camshaft profiles and hydraulically selects between the two. This technology was invented by Ikuo Kakitani, a Honda engineer.
Is the Honda i-VTEC a good engine?
The main reason why we can state that Honda VTEC engines are truly reliable and worth buying is their proven efficiency. Considering that the VTEC is a naturally aspirated engine, with 4 or 6 cylinders respectively, you wouldn’t expect a very high horsepower.
Does a DOHC have VTEC?
VTEC was introduced as a DOHC (dual overhead camshaft) system in Japan in the 1989 Honda Integra XSi, which used the 160 bhp (120 kW) B16A engine.
What is the difference between VTEC and DOHC?
Just wondering what are the main differences between DOHC vtec and SOHC i-vtec. Essentially speaking the biggest difference is the number of camshafts the engines have. DOHC engines are designed to rev higher, have peakier power outputs and PERHAPS high horsepower application.
Are DOHC engines good?
A DOHC, four valves per cylinder configuration allows better airflow at high engine speeds, resulting in better top end power. DOHC engines also allow the spark plug to be placed right in the middle of the combustion chamber which in turn promotes efficient combustion.
When did Honda stop using VTEC?
The Prelude was quietly put out to pasture in 2001, having become too refined and expensive for its own good. The Integra kept kicking for a while as the Acura RSX (it was still called “Integra” in other markets), but 2006 marked the end of the line.
What is a DOHC VTEC engine?
From the REV used in motorcycle engines, Honda developed the DOHC (Double Overhead Camshaft) VTEC system for automobiles. The DOHC VTEC improved the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
What is VTEC-E?
VTEC-E is quite different from the standard VTEC, because Honda did not design it for optimal horsepower at high RPMs, instead they designed for optimal fuel efficiency at low RPMs. VTEC-E does this by effectively forcing the engine to run as a 12 valve engine instead of its normal 16 valves.
What is i-VTEC Honda?
Honda i-VTEC (intelligent-VTEC) is a system that combines VTEC with Honda’s VTC (Variable Timing Control), a continuously variable camshaft phasing system used on the exhaust camshaft of DOHC VTEC engines. The technology first appeared on Honda’s K-series four-cylinder engine family in 2001.
What is i-VTEC and how does it work?
At the moment, i-VTEC is only implemented in the relatively low specific power output engine of the new JDM Honda STREAM van. Used in the 2.0l DOHC i-VTEC engine, it allows Honda to boost low-end and mid-range power of that engine, a characteristic very desirable for that model.
