Please complete all sections below Learning outcome LO1 Be able to read and interpret pneumatic and hydraulic fluid power diagrams 1. For each state their purpose and application. Using current standards study and explain the following statements: How a Pneumatic and Hydraulic drawing should be laid out.
The design is based on a rather simple working principle.
The compressed air is the source of energy that is stored in a high pressure cylinder. Basically this cylinder is re-filled by the compressor. But in the present case, the compressed air is supplied directly from a compressor at a pressure of bar.
When the piston is at TDC Top dead center then the inlet cam allows the inlet follower rod to open the inlet port and let the compressed air enter into the air chamber. In this situation the exhaust port is closed by the respective follower controlled by the exhaust cam.
The high pressure air introduced to the chamber passes through the inlet passage and creates a downward thrust on the piston and the piston starts moving downwards. After pushing the piston downwards the air is then reflected towards the other passage of the chamber and meanwhile the exhaust cam opens the exhaust port to leave the air by the use of a follower rod.
The inlet cam has to close the inlet port with the help of the inlet follower before the piston reaches the BDC Bottom dead center. The first evidence about compressed air used in vehicle found in 17th century, which is used by Dennis Papin royal society London While in the Mekarski air engine was used for street transport consisting single stage engine.
As a result they introduce two stage engine. The most remarkable work was done by Charles B. Hodges who remembered as father of compressed air concept applied in cars not only invent car driven by compressed air engine but also got commercial success in it.
After twelve year of research and development Guy Negre has developed an engine that could become one of the greatest technological advanced of this century. He is of French origin and Engineer by profession.
The environmental pollution in the metropolitan cities is increasing rapidly mostly because of the increased number of fossil fuel powered vehicles. It can be said as a green environmental protection vehicle with near zero pollution in the metropolitan cities. Many alternative options are now being studied throughout the world.
This can be reduce and controlled by using compressed air engine to produce energy, which runs on air which is abundantly available in atmosphere.

One of the alternative solutions can be a compressed air driven vehicle 1. It was patented in and and was tested in Paris in Another application of the compressed air to drive vehicles comes from Uruguay inwhere Armando Regusci has been involved in constructing these machines.
He constructed a four-wheeler with pneumatic engine which travelled km on a single tank in He developed compressed air- 4- cylinders engine run on air and gasoline in which he claims to be zero pollution cars.
It uses compressed air to push its pistons when running at speeds under 35 mph and at higher speeds of 96 mph, the compressed air was heated by a fuel bio fuel, gasoline, or diesel ,due to which the air expanded before entering the engine.
A fuel efficiency of about mpg was observed. Light weight vehicles are the next advancement in the development of automobiles. Reducing the weight of the vehicle has many advantages as it increases the overall efficiency of the vehicle, helps in improving maneuverability, requires less energy to stop and run the vehicle.
The latest researches are going on around the world in order to come up with innovative ideas. But global warming is also one of the problems which is affecting the man.Here is your handy-dandy cheat-sheet of rocket engines.

Plc Based Electro Pneumatic Engineering Essay. A pneumatic system is a system that uses pressurised gas to operate mechanical devices. It is powered by a compressor which then powers the mechanical devices through solenoid valve.
If the shut off valve is open (as shown), then pressure is applied to a solenoid operated servovalve. When closed, the SOV ports pressure to return.
Masters in Engineering. Pressure from an external compressor or manual pump moves the piston inside the cylinder.
As pressure increases, the cylinder moves along the axis of the piston, creating a linear force.
