As per the requirement of the assignment we have to make a survey from the market about the competitive designs of small engine and about the current standards of designing of small engine and also the cost for making it. After completing the survey we have to design a small engine for a lawn mower.

This design mainly will be focused on the following key factors like-

• The design will be for a 4-stroke engine.
• Type of joint forces acting on the engine.
• Type of shaking / vibration forces acting on the engine components.
• All the details about the bore, crank length, stroke, and the connecting rod.

Some description about the engine: -

- Internal combustion engine (IC engine) is a mechanical device that use controlled explosion of air fuel (petrol, diesel, gasoline etc.) mixtures in order to produce power for the movement of the components and hence the movement of wheels.

- In a reciprocating engine (to and fro type engine) air fuel mixture explodes and forces the connecting piston to move up and down in a cylinder.

- The motion of piston inside the cylinder is transmitted to the crankshaft which ultimately transmits the same to the wheels via connecting rod.

- Firing order of a engine is the sequence of the strokes in function.

2. Calculation of joint forces with the variation of crank angle

1. Calculation of the joint forces at the joint of connecting rod and the crank shaft: -

Fc = force on the connecting rod

As by equating the horizontal components of the forces:

F x  cos β = F

Fc =  

As per the question, in intake process.     Lie between = 0-180degree

By this we have the value of Fc  is (F to -F)
