Engine Technologies-Four stock Diesel Engine

How diesel four stock engine work

Diesel four stock engines have four steps. Because of these four steps power will generate in the engine .these stocks are

1. Intake Stroke 
2. Compression Stroke 
3. Power Stroke 
4. Exhaust Stroke

Main components of diesel four stock engine

P-Piston

How diesel four stock engine work

Intake Stroke

Intake Stroke

This is a first stock in diesel engine. In here inlet value has opened Exhaust valve has closed. All air comes into the cylinder. In here piston goes to up to down

Compression Stroke

Compression Stroke

In this step piston goes to down to up.in here inlet and Exhaust valve has closed. All air in the cylinder is compress when the piston goes to up. The compression ratio is 20:1, 18:1

Power Stroke

Power Stroke

This is a important stock in four stock engine. Both valves are closed .Power is generate in this step. When the piston reach the top of the cylinder,Injecter spray diesel to heated, Compressed air. Then diesel burn. Because of that power is generate and piston goes to down high speed.

Exhaust Stroke

Exhaust Stroke

This is last step of four stock engine.In here inlet value has closed Exhaust valve has opened. All combustion air from Power Stroke is exhaust from this stock.in this stock piston goes to down to up.

Generate Electricity from floating wind turbine

We know generate electricity from wind. A wind turbine is converts kinetic energy in the wind converts into mechanical energy. This process is known as wind power. There is some tower with a propeller on the top. Propeller is connected with a generator. When the wind is flowing, propeller will rotate. Because of that generator produce electricity.

 wind turbine

Main disadvantage is this type of turbine is it can’t be moveable to place where wind is flowing. As the solution of this problem American company has invented moveable wind power station.

 floating wind turbine

It is called High Altitude Wind Turbine. It is fully automated turbine. It is like a balloon can fill helium gas.it can made travel by using truck. This turbine located in 1000feet high on the sky. This power stations is more efficiency, It can move any place. Now it on testing. IN near future we can use these kind of power stations to generate electricity.

Generate Electricity in a Satellite and transmit to earth in future

Day by day power consume is increasing. As result of this people have to generate electrical power more. Because of that NASA is planning technology to make a solar power in space and convert it to micro wave and transmit it to the earth.

NASA is planning a make a solar power Satellite in space it consist lot of solar cell. It is shape like a wine glass. When sun light coms to this sola cell it converts to sun power to electrical power. After it convert microwave and transmit to antenna which has located in earth. It is known as Solar Power Satellite via Arbitrarily Large Phased Array / SPS-ALPHA.

This Satellite is going to make thin film mirrors. This Satellite is very big.so they are planning to make Satellite parts and after they will assemble it in space.If successful this project will make possible to answer to the world energy Crisis.

solar power Satellite in space consist lot of solar cell.

How to work hybrid vehicle ( hybrid technology)

How to work hybrid vehicle

what are the components of a Toyota hybrid Car

components of a Toyota hybrid  Car

• Power-split transmission
• Engine
• Fuel Tank
• Motor
• Generator
• Battery

components of a Toyota hybrid  Car

An important thing is a Toyota hybrid Car is Power-split transmission. It connected Fuel engine and motor to vehicles wheel according to the running speed, type of road, amount of weight in the vehicle and transmit power.

As a design Toyota hybrid Car electrical motor can run vehicle to forward without engine. Fuel engine also can supply power to wheel without electrical motor. Also electrical motor and Fuel engine both can supply power to wheel together. In this vehicle there is a computer, the computer define which method is suitable for supple to the power to wheels

Now we you can see how Power-split transmission are work are work various situation

when the vehicle travels to forward very beginning

when the vehicle travels to forward very beginning

In this position vehicle start to travel till to 15kmph.In here Only motor is supplying to the power to wheels. Battery is supplying energy to motor. In here engine does not work.

when the vehicle travels to than 15kmph speed

when the vehicle travels to than 15kmph speed

In this position fuel engine supplying power to wheel.in this position Generator also connect with Power-split transmission and generate power and charge Battery.

When the vehicle requires high torque

When the vehicle requires high torque  

when the vehicle requires high torque. Electrical motor and Fuel engine both supplies power to wheel together

When the vehicle apply break

When the vehicle apply break 

When the vehicle applies break. Electrical motor and Fuel engine both cut supplies power to wheel. Then only generator is connected to wheel via Power-split transmission. Then generate power and recharge battery. While decreasing speed, when seeped lower than 15kmph,fuel engine stop. Vehicle is run using motor.
Main purpose is using hybrid vehicle is saving energy. Hybrid technology is very useful technology for today.
