The Integra Type R (1995–2000) available in the Japanese market produces 197 bhp (147 kW; 200 PS) using a B18C 1.8-litre engine, producing more horsepower per litre than most super-cars at the time. These secondary rocker arms, which have a varying depth profile (similar to cams), are directly actuated by the camshaft, in a scissor-like manner. The technology was originally introduced to the US on the 2005 Honda Odyssey minivan, and can now be found on the Honda Accord Hybrid, the 2006 Honda Pilot, and the 2008 Honda Accord. At the switch point a solenoid is actuated that allows oil pressure from a spool valve to operate a locking pin which binds the high RPM rocker arm to the low RPM ones. The performance i-VTEC system is basically the same as the DOHC VTEC system of the B16A's. When engaging VTEC mode, a pre-defined threshold for MPH (must be moving), RPM and load must be met before the computer actuates a solenoid which directs pressurized oil into a sliding pin, just like with the original VTEC. 197000 Miles. VTEC Turbo engines come in three displacement capacities: a 1.0 liter 3-cylinder, a 1.5 liter 4-cylinder, and a 2.0 liter 4-cylinder. AMSOIL AUTO & LIGHT TRUCK LOOKUP GUIDE Disclaimer and Technical Concerns Japan levies a tax based on engine displacement,[3] and Japanese auto manufacturers have correspondingly focused their research and development efforts toward improving the performance of their smaller engine designs. Critics maintain that VTEC adds little to the VFR experience, while increasing the engine's complexity. Although it was speculated that it would first be used in 2008 Honda Accord, the vehicle instead utilizes the existing i-VTEC system. A version of i-VTEC with direct injection, first used in 2004 Honda Stream. The economy i-VTEC used in K20A3/K24A4 engines is more like the SOHC VTEC-E in that the intake cam has only two lobes, one very small and one larger, as well as no VTEC on the exhaust cam.

The Transmission Fluid Filter is not designed to be changed as part of regular maintenance. At 5500-7000 RPM, the second VTEC solenoid engages (both solenoids now engaged) so that both intake valves are using a middle, third camshaft lobe. A 2.4-liter DOHC i-VTEC four-cylinder engine that develops 177 horsepower and 161 lb-ft. of torque powers the LX and LX-P Accord Sedans. Timing refers to an angle measurement of when a valve is opened or closed with respect to the piston position (BTDC or ATDC). The primary exhaust rocker arm contacts a low-profile camshaft lobe during low-RPM engine operation. This induces swirl of the intake charge which improves air/fuel atomization in the cylinder and allows for a leaner fuel mixture to be used. The earliest VTEC-E implementation is a variation of SOHC VTEC which is used to increase combustion efficiency at low RPM while maintaining the mid range performance of non-vtec engines. Honda seemed to agree, as their VFR1200, a model announced in October 2009, came to replace the VFR800, which abandons the VTEC concept in favor of a large capacity narrow-vee "unicam", i.e., SOHC, engine.

The i-VTEC system in the R-Series engine uses a modified SOHC VTEC system consisting of one small and two large lobes. According to Honda, VCM technology works on the principle that a vehicle only requires a fraction of its power output at cruising speeds. Advanced VTEC motors still use the now standard oil pressure controlled variable cam gear angle mechanism. The high-profile camshaft lobe which normally contacts the secondary exhaust rocker arm alone during low-RPM engine operation is able to move both exhaust rocker arms together which are locked as a unit. V6 power when accelerating or climbing, as well as the efficiency of a smaller engine when cruising.

Honda incorporated the technology into the NC700 series, including the NC700D Integra, released in 2012, using a single camshaft to provide two timing routines for the intake valves. Performance i-VTEC is a combination of conventional DOHC VTEC with VTC (which operates for intake valves only). Hey everyone I'm new here but not to this site, I have a 2001 Honda Accord V6 coupe. This 12 Valve mode results in swirl of the intake charge which increases combustion efficiency, resulting in improved low end torque and better fuel economy. VTEC controls of valve lift and valve duration are still limited to distinct low- and high-RPM profiles, but the exhaust camshaft is now capable of advancing between 25 and 50 degrees, depending upon engine configuration. Carteret, NJ. If the motor is not maintaining oil pressure or reaching engine temperatures, it can cause the solenoid to fail and not activate VTEC. From this point on, the valves open and close according to the high-lift profile, which opens the valve further and for a longer time. 4 cylinder Regular fuel. The technology first appeared on Honda's K-series four-cylinder engine family in 2001. AMSOIL synthetic lubricants are the solution for drivers who want the most from their 2001 Honda ACCORD. This is because VTEC requires a third center rocker arm and cam lobe (for each intake and exhaust side), and, in the SOHC engine, the spark plugs are situated between the two exhaust rocker arms, leaving no room for the VTEC rocker arm. The low-end fuel economy improvements of VTEC-E and the performance of conventional VTEC are combined in this application. Always compare fluids and lubricants that were installed in the vehicle with those replacing them during service. It instead uses a single cam lobe per valve, and two rocker arms per valve whereby the second rocker arm has a movable pivot point, thereby providing the varying cam lift. However, each secondary intake rocker arm is shaped similar to a "Y" which allows it to contact two intake valves at once.
