3-stage VTEC. Three-stage VTEC is a multi-stage implementation of Honda's VTEC and VTEC-E (colloquially known as dual VTEC) technology, implemented in some of the company's D series engines from 1995 to the present day, allowing the engine to achieve both fuel efficiency and power. VTEC-E (for "Efficiency") is a form of VTEC that closes off one
When conditions demand VTEC operation, one oil control solenoid locks two rocker arms together, which opens both inlet valves by the same amount to improve torque in the 3 000 RPM to about 5 400 RPM range. However, at engine speeds above about 5 500 RPM, the second VTEC oil control solenoid locks the third, high-lift rocker arm to the other two
How it works. 3. Turbocharger with electronic wastegate. ‘Turbo lags’ are a typical outcome of conventional turbo engines. Accelerations tend to lag upon accelerating, as exhaust energy must rise to spin the turbines which then increase intake amount. This problem is rectified with the VTEC TURBO – using a turbocharger with electronic
checked VSS (signal)-> functioned (= I can see it at see stack display, signal comes from the ECU) did a oil and oil filter change with 10W60. checked VTEC strainer -> clean. checked oil pressure level -> between 3 and 5,5 bar (it is a SAE60 oil ) changed testwise the complete VTEC solenoid -> does also not work. VTEC Tech. Honda also uses VTEC systems on the Acura NSX sports coupe, Integra GS-R, Prelude, del Sol, Accord and Civic automobiles. How VTEC Works. At engine speeds below 7000 rpm, the Interceptor's camshafts open only one intake and one exhaust valve per cylinder. Above 7000 rpm, cams open both intake valves and both exhaust valves for each
The 3rd rocker is what forces the "high cam" profile on the intake side (SOHC VTEC) or intake and exhaust side (DOHC VTEC). This allows engines like the B18C5 (Integra Type-R) to effectively use a lower duration, low-lift camshaft profile at low RPM, but switch over to a high duration, high lift profile at higher RPM.

A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston during only one crankshaft revolution

Below is a great explanation of what it is and how it works from How Stuff Works VTEC is an acronym for Variable valve Timing and lift Electronic Control. It is a mechanism for optimizing air/fuel mixture flow through the engine. An internal combustion engine converts the chemical energy stored in fuel into thermal energy. pcyoW.
