ABSTRACT
Micro air-vehicle is a small flight vehicle that uses a lift-generating mechanism that is different from the mechanism used for large aircrafts. In micro air- vehicles, one of the methods for creating lift is a special flapping mechanism, which consists of translation and rotational motions of wings. This is adopted from one species of insect Encarsia Formosa. For this purpose, a 6-link mechanism is designed for three positions of wings by synthesis using kinematic inversion, and dynamic force ....etc

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 4A-GE 20-Valve engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.

VVT-i, introduced in 1996, varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft positi ....etc

ABSTRACT


MICRO AIR VEHICLES




Have you ever thought of a class of air vehicles which are less than 15 cms in size (most prominent linear dimension), can hover for two to three hours in air at a velocity of 20 to 30 mph at an altitude of 600 meters or even higher. This seminar will give you an idea of such vehicles called MAVâ„¢s (micro air vehicles). A dwell into the design and aerodynamics of such vehicles would be quit ....etc

ABSTRACT
Gone through a rigorous four weeks training under the guidance of capable engineers and workers of bajaj motors limited, headed by the executive director of the company Mr. J.C Jha in the machining plant situated in Narsinghpur, Gurgaon, Haryana.
The training was specified under the CAMSHAFT department of the machining unit. Working under the cam machining department the basic grinding, scaling and machining was shown on heavy to medium duty lathes planted in the same ....etc

Valve timing is the regulation of the points in the combustion cycle, at which the valves are set to open and close. Since the valves require a finite period of time in which to open or close without abruptness, a slight lead-time is always necessary for proper operation. The design of the valve-operating cam provides for the smooth transition from one position to the other, while the cam setting determines the timing of the valve.

In a typical four-stroke engine, the inlet valve is set to open before TDC (top dead centre), towards the end 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

SYNOPSIS
Until recently, a manufacturer used one or more camshafts (plus some pushrods, lifters and rocker arms) to open and close an engine's valves. The camshaft/camshafts was turned by a timing chain that connected to the crankshaft. As engine rpm's rose and fell, the crankshaft and camshaft would turn faster or slower to keep valve timing relatively close to what was needed for engine operation. Unfortunately, the dynamics of airflow through a combustion chamber change radically between 2,000 rpm and ....etc
