subject: Honda V-tec Motors ; A Term Of Legend To The Import Enthusiasts. [print this page] The number one Japanese car manufacturer in the world, Honda has made another remarkable advancement in their technology called VTEC. It stands for Variable Valve Timing and Lift Electronic Control. This means variable valve control system. Honda has created a niche in the society and made a mark for itself by being the first to become the most successful developer of lift control systems and variable valve timing system.
Sports bikes during the 80s persistently insisted on extremely powerful engines thus influencing Honda to produce such cutting edge engines. High power-driven output and driveability were the main aspects of this engine. Thus the first ever Revolution Modulated Valve Control, or REV with a regulator pausing device was created whose function was to effectively stop the progress of multiple valves that were required to aid optimum airflow thereby attaining stableness and amplify smoothness for medium to low operations of engines.
Honda VTEC engines have two camshaft profiles, medium to high and low to medium speed engines and changeable valve opening valves.
Slowly from this Honda developed the VTEC engines. They have both two camshaft profiles, from middle to high speed engines and low to medium engine speeds, variable valve opening valves. The very first automobile to be privileged with Honda VTEC engines were the Civic CRX SiR and the 1989 JDM - Spec Integra which uses 160 hp B16A DOHC engine. In 1991, the American car industry was able to obtain Honda VEC engines in the Acura NSX super sports car.
The Honda VTEC engines were initially created for the Double Overhead Camshaft or the DOHC gasoline engines. The main objective of it is being able to switch from fuel saving operating mode to a performance operating mode. Low fuel burning and enhanced burning up of fuel can now be attained through small cam profile and low speed valve timing.
The Honda VTEC engines specializes on improving fuel consumption of low profile cams to high profile cams that increases power output through a locking pin that connects the lobes of the two cam profiles at certain engine speeds. This system works much like a mechanical turbocharger or compressor by making a higher "swirl" effect and exceptional filing efficiency that materializes in high power output.
Different variations of Honda VTEC engines have been created by this world renowned automobile manufacturer. They are the VTEC - E, the 3 stage VTEC, I - VTEC and the AVTEC. Different engine have different outputs and the fuel intake requirements. Honda has been able to create reformed valve systems to cater to individual requirements. This Honda VTEC engines could also be used in Single Overhead Camshaft engine or the SOHC but it would compromise the advantages of the high profile cam on the exhaust part.
They have converted valve systems to harmonize diverse engine outputs and fuel intake requirements. The Honda VTEC engines could as well be useful to Single Overhead Camshaft engine or the SOHC but the benefits of the high profile cam on the exhaust region would be lost.
We are sure that with every passing day Honda will continue to supply the desires of the industry with advanced technology and at the same time extreme driving satisfaction.
