🪁 How Does A Vtec Engine Work

First-Generation CR-V Engines (1997-2001) The original 1997 Honda CR-V had a 2.0-liter B20B I-4 engine. It pushed out 126 horsepower and 133 lb.-ft. of torque. That’s pretty decent for 1997, considering it was actually an Acura Integra engine. autiger. 328 posts · Joined 2006. #9 · Aug 4, 2010. dude, there is a reason why skunk2 cams work for k20a3, k24a1, and k24a4's. The heads are the SAME, yes the ports are a little different, but the valvetrain components are the same. This information is in fact in the thread everyone is telling you to look at in detail. Ktuner changed it based on ideal performance over the power band. Vtec is intended to account for power drop off at high RPMs, pushing the activation lower would net no benefit, or actually hamper performance. You can look at the power maps from their dyno and see they "did it right". OP. How does the DOHC engine work. For any die-hard Honda fan, the term i-VTEC or VTEC would be synonymous to top-notch performance and fuel efficiency. If you are curious to know how the VTEC does its magic, you are at the right place. But before knowing how the VTEC works, let’s have a look at how a basic DOHC engine functions. The first Honda automobiles to receive the VTEC system were the 1989 JDM-spec Integra and Civic CRX SiR, which used a 160 hp B16A DOHC engine. The American market received the VTEC system in 1991 Overview of iVTEC. An engine is considered internal combustion if the fuel’s chemical energy is released inside and used immediately for mechanical effort. The late 1800s saw the creation of the internal combustion engine. Nikolaus Otto is regarded as the creator of the contemporary IC engine and the industry’s pioneer (1832-1891). Rough engine idle. One of the top symptoms of a bad VTEC solenoid is very poor idle at low RPM which clears at high RPM. When your Honda VTEC solenoid is bad, it prevents the valve timing from retarding or advancing as it should. This causes the engine to exhibit performance issues, including rough idle and poor acceleration. The Pilot is a mass-produced vehicle made by Honda so they are relatively easy to work on and parts are affordable. The most common problem that has been reported with the Pilot is warped brake rotors. These have been known to get warped around 50,000 miles and they cost about $200 to $250 to replace. The i-VTEC system was implemented into more modern K series engine, as opposed to the VTEC system of the older B series engines. There is a performance i-VTEC system, and an economy i-VTEC system. The performance variant allowed three cam lobes per cylinder for both intake and exhaust, whereas the economy i-VTEC system only possesses two lobes The VTEC system has been around since 1989, and was first introduced on a 1.6 litre dual over-head cam DOHC) engine in a Honda Integra. These engines have a separate camshaft for the intake and exhaust cam, and the VTEC changes the profile of both camshafts at the same time. Later, Honda started introducing VTEC also in single cam ( SOHC VVA Applications. Abstract: Variable valve actuation (VVA) technologies are used to add flexibility to the engine’s valve train by enabling variable valve event timing, duration and/or lift. The main types of VVA technologies include valve timing control (VTC), variable valve lift (VVL) and camless valve trains. Classification of VVA Technology. Here’s a step-by-step guide on how to do it: 1) Locate the VTEC solenoid on your engine. It should be located near the top of the engine, on the passenger side. 2) Unplug the electrical connector from the VTEC solenoid. 3) Using a pair of pliers, remove the two 10mm bolts that hold the VTEC solenoid in place.
