Presentation within is a synopsis of the conceptual development of a piezoelectric controlled hydraulic actuator. This actuator was develop for use as a replacement for the camshaft in an internal combustion engine (ICE). Its development results in a new device; called, the camless engine (CLE).
The objective of the project was to prove the concept of a CLE. More specifically, it is a electro/hydraulic device capable of producing engine valve displacement at typical automotive demands. The goals for maximum displacement and frequency are 10 mm and 50 Hz, respectively. In general, the unit must be capable of varying engine valve displacement and valve timing.
The system utilize a customize piezoelectric stack and hydraulic spool valve combined with an in-house designed hydraulic amplifier. Control is facilitate by a function generator, and feedback is monitored with an oscilloscope. The resulting system is capable of displacing an engine valve to nearly 11 mm, and frequencies up to 500 Hz have been obtained. As the ability of piezoelectric control of hydraulics for use as an ICE valve actuator.
SYNOPSIS:
INTRODUCTION WORKING OF PUSH ROD ENGINE AN OVERVIEW OF CAMLESS ENGINE
Camless valve train
Hydraulic pendulum
Valve opening COMPONENT OF CAMLESS ENGINE ADVANTAGES AND DISADVANTAGES CONCLUSION
INTRODUCTION
The cam has been an integral part of the IC engine from its invention. The cam controls the “breathing channels” of the IC engines, that is, the valves through which the fuel air mixture (in SI engines) or air (in CI engines) is supplied and exhaust driven out. Besieged by demands for better fuel economy, more power, and less pollution, motor engineers
