Honda i-VTEC (intelligent-VTEC)[5] 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. Performance i-VTEC is a combination of conventional DOHC VTEC with VTC (which operates for intake valves only). Timing refers to an angle measurement of when a valve is opened or closed with respect to the piston position (BTDC or ATDC). The intake and exhaust rocker shafts contain primary and secondary intake and exhaust rocker arms, respectively. All; Parts; Accessory Components . TruYou Member Categories. Most Honda or Acura 4 cylinder powered vehicles sold in the United States of America used i-VTEC by the 2002 model year with the exception being the 2002 Honda Accord. Also called 16-valve mode, this method resembles a normal engine operating mode and improves the mid-range power curve. Honda J-Series Engines using i-VTEC combine SOHC VTEC operation with Honda VCM (Variable Cylinder Management) variable displacement technology to improve fuel economy under light loads. Example: EPA estimates for the 2011 (271 hp SOHC 3.5L) V6 Accord are 24 mpg combined vs. 27 in the two 4-cylinder-equipped models. Vehicle. Performance Improver Gasoline Additive, AMSOIL Synthetic Multi-Purpose Grease NLGI #2. The primary rocker arms are actuated by the secondary (drum attached) rocker arms. The 2-litre DOHC i-VTEC I integrates the i-VTEC system which uses the VTEC and VTC which uses a direct injection system for an air-fuel ratio of up to 65:1 for an unprecedented level of ultra-lean combustion. High-Low. Using these inputs, the ECU is programmed to switch from the low lift to the high lift cam lobes when certain conditions are met. The Transmission Fluid Filter is not designed to be changed as part of regular maintenance. Search. The drum will only rotate to advance or retard the position of the secondary rocker arms, to take advantage of their varying profiles. JDM 1998-1999-2000-2001-2002 HONDA ACCORD F23A2.3L 4 CYL SOHC VTEC AUTOMATIC TRANSMISSION. Correspondingly, VTEC attempts to combine low-RPM fuel efficiency and stability with high-RPM performance. Each exhaust valve on the J37A2 corresponds to one primary and one secondary exhaust rocker arm. [9], A related U.S. patent (6,968,819) was filed on January 5, 2005. 2001 Honda ACCORD SEDAN Change Vehicle . In newer version of 3-Stage i-VTEC combined VTC and PGM-FI to allow ECU to control full range of mode to archive greater fuel economy improvements and performance. Honda's advanced VTEC technology departs greatly from its previous incarnations by no longer relying on switching between two sets of lobes on a given camshaft. The system electronically deactivates cylinders to reduce fuel consumption.

There are 3 intake cam lobes: 2 for the low-RPM mode (1 for almost closed valve, 1 for normally opened) and 1 for the powerful mode when the VTEC solenoid is activated. As the engine's speed and load increase, both valves are needed to supply a sufficient mixture. Stable combustion is achieved by using less fuel than conventional direct injection engines which have an air-fuel ratio of 40:1. The switch-over point is variable, between a minimum and maximum point, and is determined by engine load. The two types of engines are easily distinguishable by the factory rated power output: the performance engines make around 200 hp (150 kW) or more in stock form, while the economy engines do not make much more than 160 hp (120 kW). i-VTEC VCM was also used in the 1.3-liter LDA engine used in the 2001-2005 Honda Civic Hybrid.[6]. [citation needed]. This engine was only available in the EX and LX trims and produced significantly more power than the non-VTEC … 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 first type is for performance engines like the K20A2 or K20Z3 used in the 2002-2006 RSX Type S or the 2006-2011 Civic Si and the second type is for economy engines like the K20A3 or K24A4 used in the 2002-2005 Civic Si or 2003-2007 Accord. 2001 Honda ACCORD SEDAN EX 4 Speed Automatic Catalog; New Vehicle; Search All Vehicles; Clear Recent Vehicles; Search Bar 8. The ideal engine would have fully variable valve timing, lift and duration, in which the valves would always open at exactly the right point, lift high enough and stay open just the right amount of time for the engine speed and load in use. A version of i-VTEC with direct injection, first used in 2004 Honda Stream. At low RPMs, the small lobe locks onto one of the larger lobes and keeps one of the intake valves partially open during the compression cycle, similar to the Atkinson Cycle. The low-end fuel economy improvements of VTEC-E and the performance of conventional VTEC are combined in this application. AMSOIL AUTO & LIGHT TRUCK LOOKUP GUIDE Disclaimer and Technical Concerns 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. 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. Both intake and exhaust cams have 3 cam lobes per cylinder. Vehicle Specifications. With free shipping on orders over $100, and an average 25% savings for Preferred Customers, shopping online is the fastest way to get AMSOIL products to your doorstep. Honda originally planned to produce vehicles with AVTEC engines within next 3 years. The VTC is available in the economy and performance i-VTEC engines.

Simply shop amsoil.com and add a P.C. This engine was an optional engine as an upgrade from the 2.3- liter non-VTEC Accord DX. The switching operation between the two cam lobes is controlled by the ECU which takes account of engine oil pressure, engine temperature, vehicle speed, engine speed and throttle position. The camshaft is surrounded by a partially open drum which has secondary rocker arms attached to it via a pivoting point. 23/30 MPG. Direct injection 2.0L DOHC i-VTEC I gasoline engine. At higher RPM, both intake valves run off the larger intake cam lobe, improving total air flow and top-end power. The primary exhaust rocker arm contacts a low-profile camshaft lobe during low-RPM engine operation. V6 power when accelerating or climbing, as well as the efficiency of a smaller engine when cruising. Hey everyone I'm new here but not to this site, I have a 2001 Honda Accord V6 coupe. With these two technologies combined Honda has developed an infinitely variable valve timing and lift system ("VVTL"). Previous versions of VTEC included only staged VVTL i.e. In The Past I Have Replaced The Timing Belt & Water Pump On 4 Cyl Hondas, But This Is The First One With Balance Shafts. However, each secondary intake rocker arm is shaped similar to a "Y" which allows it to contact two intake valves at once. The United States market saw the first VTEC system with the introduction of the 1991 Acura NSX,[4] which used a 3-litre DOHC C30A V6 with 270 bhp (200 kW). There are two types of i-VTEC K series engines which are explained in the next section. The primary rocker arm contains the VTEC switching piston, while the secondary rocker arm contains the return spring. If either does not confirm, then you may need to troubleshoot those two issues independently. Introduced as a DOHC (Dual overhead camshaft) system in Japan in the 1989 Honda Integra[1] XSi which used the 160 bhp (120 kW) B16A engine. Phasing is implemented by a computer-controlled, oil-driven adjustable cam sprocket. 1 - 150lbs 2 -25lbs 3 - 155lbs 4 - 150lbs - Answered by a verified Mechanic for Honda We use cookies to … In basic form, the single cam lobe and follower/rocker arm of a conventional engine is replaced with a locking multi-part rocker arm and two cam profiles: one optimized for low-RPM stability and fuel efficiency, and the other designed to maximize high-RPM power output. Protect your ACCORD in any driving condition with our specially formulated motor oils. Lift refers to how much the valve is opened. VTEC (Variable Valve Timing & Lift Electronic Control) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. 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. Thus, through varying the position of the drum about its axis, each cam profile is changed to an optimal height for maximum engine performance without sacrificing fuel efficiency at lower speeds.[12]. You will receive an immediate savings on products for your 2001 Honda ACCORD. Honda also applied the system to SOHC (single overhead camshaft) engines such as the D-Series and J-Series Engines, which share a common camshaft for both intake and exhaust valves. By reading the temperature gauge, when the car is running, we want to make sure it reaches 178 degrees. The 2.3-liter VTEC engine was only used in the sixth-generation Honda Accords from 1998 through 2002. Learn more about the 2001 Honda Accord. Valve - Rocker Arm (VTEC) (L4) for 2001 Honda ACCORD SEDAN. The improvements in low-RPM performance, which is where most street-driven automobiles operate a majority of the time, occur in trade for a power and efficiency loss at higher RPM ranges. 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. Shop online and get your products in 3 business days or less. I just need the firing order for a honda accord 19991 v/6 3.0 what side is the number one cilinder thanks for you hellp For the 1999 Honda Accord 3.0L SOHC V6 (VTEC): Firing Order: [10][11], Advanced VTEC has a standard camshaft and rocker arms, attached as they normally are with camshaft overhead, and rocker arms pushing down on the poppet valves. VTEC implementation on the exhaust rocker arms causes the turbo to be spooled quicker, eliminating turbo lag. From idle to 2500-3000 RPM, depending on load conditions, one intake valve fully opens while the other opens just slightly, enough to prevent pooling of fuel behind the valve, also called 12-valve mode. Honda's J-Series SOHC engines use an entirely different system also, confusingly, marketed as i-VTEC. Because of this, at low RPM, when VTEC is not engaged, one of the two intake valves is allowed to open only a very small amount due to the mild cam lobe, forcing most of the intake charge through the other open intake valve with the normal cam lobe. Combustion control through the use of high-precision EGR valves and a newly developed high-performance catalyst enable the 2.0 litre DOHC i-VTEC I lean-burn direct injection engine which qualify as an Ultra Low Emissions Vehicle. At low RPM only one valve on the intake opens fully, promoting combustion chamber swirl and improved fuel atomization. The same year, Europe saw the arrival of VTEC in the Honda Civic and Honda CRX 1.6i-VT, using a 150 bhp (110 kW) B16A1 variant. This variant of the VTEC-E is used in some D-series engines. Both engine load and RPM affect VTEC. Specifications contained on this website are based on manufacturers' information and were believed accurate at the time of publication. The trade-off was that Honda's SOHC engines benefited from the VTEC mechanism only on the intake valves. However, the valvetrain has the added benefit of roller rockers and VTC continuously variable intake cam timing. Always compare fluids and lubricants that were installed in the vehicle with those replacing them during service. Honda VFR800(A) (RC46) (2002–2009) Engine Type 781cc liquid-cooled four-stroke 90-degree DOHC V4; Bore and Stroke 72 mm x 48 mm; Compression Ratio 11.6:1; Valve Train VTEC chain-driven DOHC, 4 valves per cylinder; earlier versions were non-VTEC, gear driven DOHC, 4 valves /cylinder; Pre-cat converter delivered 110 BHP However, beginning with the J37A2 3.7L SOHC V6 engine introduced on all 2009-2012 Acura RL SH-AWD models, SOHC VTEC was incorporated for use with intake and exhaust valves, using a total of six cam lobes and six rocker arms per cylinder. Instead, there are two different intake cam profiles per cylinder: a very mild cam lobe with little lift and a normal cam lobe with moderate lift. This sliding pin connects the intake rocker arm followers together so that, now, both intake valves are following the "normal" camshaft lobe instead of just one of them. Find detailed specifications and information for your 2001 Honda Accord Sedan. This in essence supersedes VTEC and the earlier VTEC-E implementations since the fuel and low RPM torque benefits of the earlier VTEC-E are combined with the high performance of the original VTEC.

Although it was speculated that it would first be used in 2008 Honda Accord, the vehicle instead utilizes the existing i-VTEC system. It is my second car, and by all means it is a godsend compared to what I owned before. The switch-down back from high to low RPM cams is set to occur at a lower engine speed than the switch-up (representing a hysteresis cycle) to avoid a situation in which the engine is asked to operate continuously at or around the switch-over point. With filter 4.5 quarts After refill check oil level. If any discrepancies are noted, they can be simply reported to AMSOIL by clicking on the "Report a Problem" link. The shape of the lobes determines the timing, lift and duration of each valve. JDM 98-02 Honda Accord 2.3L F23A SOHC VTEC Engine & Automatic Transmission F23A1 (Fits: 2001 Honda Accord) $799.00 1998-2002 HONDA ACCORD 2.3L SOHC 4 CYL VTEC ENGINE AUTOMATIC TRANS JDM F23A (Fits: 2001 Honda Accord) DOHC VTEC engines soon appeared in other vehicles, such as the 1992 Acura Integra GS-R (160 bhp (120 kW)B17A1), and later in the 1993 Honda Prelude VTEC (195 bhp (145 kW) H22A) and Honda Del Sol VTEC (160 bhp (120 kW) B16A3). Honda CR-Z able to switch between low-end mode and standard mode from 1000 rpm to 2250 rpm uninterrupted and engage to high cam mode from 2250 rpm upward on SOHC. One method for increasing performance into a static displacement includes forced induction, as with models such as the Toyota Supra and Nissan 300ZX which used turbocharger applications and the Toyota MR2 which used a supercharger for some model years. 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.

The ability for Honda to switch between Atkinson cycle and normal cycle allows excellent fuel efficiency without sacrificing too much performance. 2001 Honda ACCORD SEDAN Change Vehicle. [7] The performance i-VTEC system is basically the same as the DOHC VTEC system of the B16A's. 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 exhaust phase varies from fully retarded at idle to somewhat advanced at full throttle and low RPM. AMSOIL products are subjected to rigorous third-party, industry-standard testing so you can rest assured you’re getting maximum protection. The VTEC system uses two (or occasionally three) camshaft profiles and hydraulically selects between profiles. I recently purchased a 2001 Honda Accord EX Coupe with a 4 cylinder engine with VTEC, manual transmission, and 110K miles on it. 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 lowest RPM for activating the VTEC is 2500, or it may be higher if the load is weak - ECM dependant. Duration refers to how long the valve is kept open. One primary intake rocker arm corresponds to each secondary intake rocker arm. Joseph Maldonado. 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. In 2003, Honda introduced an i-VTEC V6 (an update of the J-series) that includes Honda's cylinder deactivation technology which closes the valves on one bank of (3) cylinders during light load and low speed (below 80 km/h (50 mph)) operation. The engine is able to run on 3, 4, or all 6 cylinders based on the power requirement, essentially getting the best of both worlds. Use this guide to replace your Honda Accord's spark plugs.
