Engine Technology-Two stock engine

How two stock engine works

Tow stock engine has two steps. These are Up Stroke and Down Stroke

Up Stroke - Intake and Compression

In this stock piston goes to down to up. In this step there is air fuel mixture inside cylinder. When piston goes to up air fuel mixture compressed. Then air Fuel mixture comes to the bottom side. End of this stock air fuel mixture compressed and spark plug ignite. Then air fuel mixture will burn. Then force will generate up side of piston and piston goes down very quickly. Up stock is combination of   Intake stock and Compression

Down Stroke - Power and Exhaust

Down Stroke is combination of Power and Exhaust stock. In this stock piston goes to up to down. When the piston goes down exhaust valve is opened. Combustion air goes to out. Then bottom side fuel and air mixture pull and it will comes to intake valve.

Tow stock engine has some advantages

• Every revolution has a power stock.
• It is more efficiency than four stock engines.
• It will reduce fuel west
• Engines maintain cost is very low.

Tow stock engine has some disadvantages

• Should mixed lubrication oil with fuel.
• Faster wear and shorter engine life than a four stroke
