Hello sir, I am ramesh being a ME student i am intrested to present a paper on cam less engine i search in the net and came to know that it is already in reasearch by some companies and they are using elctro-mechanical valve actuator and microprocessor to actuate the actuators. still some costraints are there to develop a camless engine. my doubt is, can we replace the micro processor with micro controller and this can be used to control some other components and elctro-mechanical valve actuator with servo motor
so please give me a clear idea ....etc

Introduction

TThe 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 around the world are pursuing a radical camless design that promises to deliver the internal-combustion engine's biggest efficiency improvement in years. The aim of all t ....etc

Camshaft


Double overhead cams control the opening and closing of the valves
The camshaft is used in IC Engines to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes or cams protruding from it, one for each valve. The cams force the valves open by pressing on the valve, or on some intermediate mechanism, as they rotate.
The relationship between the rotation o ....etc

OVERHEAD CAMSHAFT ENGINE
* INTRODUCTION :-
OHV means OverHead Valve –
An engine design where the camshaft is installed inside the engine block and valves are operated through lifters, pushrods and rocker arms (an OHV engine also known as Pushrod engine).
Although an OHV design is a bit outdated, it has been successfully used for decades. An OHV engine is very simple, has more compact size and proven to be durable.
* Classification :-
Single OverHead Cam
Double OverHead Cam
Pushrod Engines
* Single O ....etc
