Wooden Air Engine

1. INTRODUCTION

Air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air to mechanical work through either linear or rotary motion. It has existed in many forms over the past two centuries, ranging in size from hand held turbines to engines of up to several hundred horsepower. Some types rely on pistons and cylinders, others use turbines. Many compressed air engines improve their performance by heating the incoming air, or the engine itself. Pneumatic motors have found widespread success in the hand-held tool industry and continual attempts are being made to expand their use to the transportation industry. However, pneumatic motors must overcome inefficiencies before being seen as a viable option in the transportation industry.

3. FABRICATION PROCESS

1.     CUTTING OF PARTS

Following Parts are prepared using carpenting BOSCH tools like jig-saw.sander,roter etc:

·         Flywheel                                      • Piston rod

·         Control rod

·         Crankshaft

·         Piston Housing

·         Bearing block

·         Cylinder mount

2.     ASSEMBLY OF PARTS

·        We assembled the piston housing using wood screw , super-glue and fevicol.

·        The valve slider was connected to crankshaft such that the control rod moves freely.

·        Fix the bearing block onto the base as per requirement.

·        Then ,we connect the flywheel to the crankshaft such that flywheel rotates with the crankshaft.

·        The connecting arm was attached to the piston such that it moves freely and other arm was connected periphery of the flywheel such that piston moves connecting arm rotates the flywheel.

·        Piston housing was mounted on the cylinder mount and cylinder mount was nailed on the base.

·        The bearing block was closed such that crankshaft was placed between two bearing block and crankshaft axis passing through the holes in the bearing blocks.
