How big is a Honda Civic EJ7 VTEC-E?
Feature is installed system VTEC-E. EJ7 (D16Y5) is equal to the displacement of 1.6 liters, and was named HX. There were also versions 1.6IES, 1.6Is and VTI. Effective Compression Ratio D16Y5 — 9.56; Variations of engine power from 115 to 127 hp. But look at each complete set separately.
Where are the intake valves located in Honda VTEC?
In the SOHC VTEC implementation (diagram on the right), Honda put a wild-cam lobe for the intake valves in the space between the two rocker arms. Note that the two exhaust rocker arms are separated by the two intake rocker arms and the “tunnel” for the sparkplug cable connector.
What’s the difference between Honda Civic EJ6 and D16Y5?
Unlike EJ6 ( D16Y7 ), EJ7 has motor D16Y5. Feature is installed system VTEC-E. EJ7 (D16Y5) is equal to the displacement of 1.6 liters, and was named HX. There were also versions 1.6IES, 1.6Is and VTI. Effective Compression Ratio D16Y5 — 9.56; Variations of engine power from 115 to 127 hp. But look at each complete set separately.
Which is the first Honda engine to use VTEC?
The first engine to benefit from VTEC is the legendary B16A, a 1595cc inline-4 16Valve DOHC engine with VTEC producing 160ps and first appearing in 1989 in the JDM Honda Integra XSi and RSi. Examine the diagram of a typical Honda DOHC PGM-Fi non-VTEC engine on the left, in this case the 1590cc ZC DOHC engine.

What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
What do the intake valves do in VTEC?
VTEC® operates the engine’s 12 intake valves in two distinct modes. At low engine speeds, the intake valves follow low lift and relatively short duration cam profiles. At high engine speeds the valves switch to high-lift, long-duration mode to deliver the best volumetric efficiency.
