DIESEL ENGINE 4 STROKE

Diesel Engine 4 Stroke – Physics Equipment

The Diesel Engine block models a diesel-fuel, compression-ignition engine with a speed governor. The engine runs at a variable speed that you can control with a Simulink throttle signal. The throttle signal directly controls the output torque that the engine generates and indirectly controls the speed at which the engine runs. If the engine speed exceeds the maximum speed that you specify, the engine generates no torque. The model does not include the air-fuel dynamics of combustion.

 The block accepts the throttle signal through a Simu link in port. This signal specifies the engine torque as a fraction of the maximum torque possible in a steady state at a fixed engine speed and should lie between 0 and 1. A throttle signal below zero is interpreted as zero; above one, as one.

 To prevent engine power and torque from becoming negative, the block imposes an upper limit on the maximum engine speed itself. If the maximum speed you specify exceeds this limit, the block issues an error that indicates what the upper limit is.

• 4 Stroke Diesel Engine is a model that represents the internal structure of a diesel engine.
• Internal surfaces are finished in different colors to indicate air, fuel, gas mixture, and exhaust gas content.
• Includes cam operated jerk pump and manually operated air inlet diaphragm injection nozzle and starting valve.
• Crankshaft can be rotated by hand wheel to show the operating cycle.
• Firing point of the engine is shown with a lamp which glows at the correct point in the cycle.
• Cast alloy construction on polished wooden base.
