The Magnetic Field

As we are moving towards the developed country, the need of fossil fuel is increasing day by day with increasing population. We need alternative to replace fossil fuel. In IC engine, the chemical energy get converted into mechanical energy, i.e., the low grade energy get converted into high grade energy. The IC engine we use cause more pollution. So to overcome this problem, the electromagnetic force and compressed air is use to run the engine. The solenoid compressed hybrid air engine which uses electric energy and compressed air to run, can replace the use of IC engine. As we pass current through the copper wire winding, the magnetic field generated near the copper wire. The polarity of the magnetic field can vary according to the current. The magnet attached at the piston get attracted up as the polarity of permanent magnet and this force is transferred to the connecting rod and crankshaft assembly, which transfer the reciprocating motion of piston into rotating motion of crankshaft and finally the flywheel. The electromagnetic engine should be more compatible. The electromagnetic engine does not require extra components like cam follower, valves, fuel pump, injectors, fuel tank etc. The strength of magnetic force can be increase by varying the input voltage and current.

The Mathematical Model

To eliminate the pollutants exhausting, this paper presents an idea of using compressed air as the power source for engines. Instead of an internal combustion (IC) engine, this automobile is equipped with a compressed air engines (CAEs), which transforms the energy of the compressed air into mechanical kinematic energy. Through analysis of the working process of a CAE, the mathematical model is setup. Experiments are carried out to verify the engine performance and the basic model’s validity. By selecting the appropriate reference values, the mathematical model is transformed to a dimensionless expression. The dimensionless speed and efficiency characteristics of the CAE are obtained. Through analysis, it can be obtained that the dimensionless average rotating speed is mainly determined by the intake duration angle, the dimensionless inertia parameter, the dimensionless exhaust pressure, and the scale factor of exhaust valve. Moreover, the efficiency of the CAE is mainly determined by the dimensionless exhaust pressure, the intake duration angle and the dimensionless cylinder clearance. This research can be referred to in the design of CAE and the study on optimization of the CAE.

The purpose of this paper is to investigate working performance for a four-stroke piston type compressed air engine (CAE) via experimental research. A conventional internal combustion engine(IC engine) is modified to a four-stroke CAE and a mathematical model is set up. Working performances are investigated by output torque, power, air consumption, exhaust pressure, exhaust temperature and cylinder pressure on a test bench. The CAE is installed on a vehicle for the road test. The experiment and analysis show several meaningful results. The increase of the supply pressure will result in the increase of the rotational speed, and it can effectively improve the output torque and power. However, it can lead to an increase in air consumption. The success of this application demonstrates compressed air cars are likely to be industrialized duo to their zero pollution and zero emissions.
