Presentation Description

Outboard engines are classified into two types one is 2 stroke outboard engines and another one is 4 stroke outboard engines. Both these outboard engine has its own advantages and disadvantages. In 2 stroke outboard engine the crank shaft take only one revolution to complete the entire process cycle of the engine. This happens when the cycle starts with a compression stroke and combining with combustion stroke at the end. This mechanism makes the 2 stroke outboard engine to generate high specific power.

INTRODUCTION:

INTRODUCTION Outboard engine is the most important part in a boat. Outboard engine is used mostly in marine propulsion in all the types of boat. These engines have a spark ignition system and an internal combustion engine. Outboard engines are attached to the rear end of the boat, which makes them to propel through water.

COMPONENTS OF OUTBOARD MOTOR:

COMPONENTS OF OUTBOARD MOTOR There are three important components in an outboard engine; they are gear case assemblies, outboard mid section and outboard power powerhead. The midsection of the outboard engine contains tilt/trim mechanism, steering and housing assemblies.

OUTBAORD ENGINE TYPES:

OUTBAORD ENGINE TYPES O u t bo a r d e ng i n e s a r e c l a ss i f i e d i n t o two types one is 2 stroke outboard engines and another one is 4 stroke outboard engines. Both these outboard engine has its o w n a dv a n t a g e s a n d d i s a dv a n t a g e s . 4 stroke outboard engines are widely used in most of the boats.

WORKING PRINCIPLE OF 2 STROKE OUTBOARD ENGINE:

WORKING PRINCIPLE OF 2 STROKE OUTBOARD ENGINE In 2 stroke outboard engine the crank shaft take only one revolution to complete the entire process cycle of the engine . This happens when the cycle starts with a compression stroke and combining with combustion stroke at the end . This mechanism makes the 2 stroke outboard engine to generate high specific power .

CONCLUSION:

CONCLUSION Even though the 2 stroke outboard engine has some drawback, most of the people still prefer it because it is fun to ride. Four stroke outboard engines are dominating the market for the past few years, but 2 stroke outboard engines are still used widely. Most of the companies started experimenting with crankcase volume and changing the exhaust pipes of the outboard engine to make it more efficient.
