I-VTEC
INTRODUCTION
The most important challenge facing car manufacturers today is to offer vehicles that deliver excellent fuel efficiency and superb performance while maintaining cleaner emissions and driving comfort. This seminar deals with i-VTEC (intelligent-Variable valve Timing and lift Electronic Control) engine technology which is one of the advanced technology in the IC engine. i-VTEC is the new trend in Honda 's latest large capacity four cylinder petrol engine families.
An internal combustion is defined as an engine in which the chemical energy of the fuel is released inside the engine and used directly for mechanical work. The internal combustion engine was first conceived and developed in the late 1800’s. The man who is considered the inventor of the modern IC engine and the founder of the industry is Nikolaus Otto (1832-1891).
Over a century has elapsed since the discovery of IC engines. Excluding a few development of rotary combustion engine the IC engines has still retained its basic anatomy. As our knowledge of engine processes has increased, these engines have continued to develop on a scientific basis. The present day engines have advances to satisfy the strict environmental constraints and fuel economy standards in addition to meeting in competitiveness of the world market. With the availability of sophisticated computer and electronic, instrumentation have added new refinement to the engine design.
What is VTEC? VTEC (standing for Variable valve Timing and lift Electronic Control) does Honda Motor Co., Ltd. develop a system. The principle of the VTEC system is to optimize the amount of air-fuel charge entering, and the amount of exhaust gas leaving, the cylinders over the complete range of engine speed to provide good top-end output together with low and mid-range flexibility. VTEC system is a simple and fairly elegant method of endowing the engine with multiple camshaft profiles optimized for low and high RPM operations.
