The 3-2-1 principle in design refers to the minimum number of reference points needed to properly locate a part for machining or assembly.

• 3 points are used to position the part in the X, Y, and Z axes

• 2 points are used to prevent rotation around the X and Y axes

• 1 point is used to prevent movement along the Z axis

• Example: Using 3 pins to position a part on a fixture for machining

Swirl in engine refers to the rotational motion of air or fuel mixture inside the combustion chamber, improving combustion efficiency.

• Swirl helps in better mixing of air and fuel, leading to more efficient combustion.

• It can improve fuel economy and reduce emissions.

• Examples include swirl-inducing intake ports or valves in engines.

Symptom of piston seizure due to lubrication system failure is engine overheating and loss of power.

• Engine overheating

• Loss of power

• Increased engine noise

• Visible damage to piston or cylinder walls

Squish in engine refers to the process of compressing the air-fuel mixture in the combustion chamber before ignition.

• Squish helps in creating turbulence for better mixing of air and fuel

• It also helps in increasing the efficiency of combustion

• Squish is achieved by the design of the combustion chamber and piston crown

Thermostat regulates the flow of coolant in the engine cooling system to maintain optimal operating temperature.

• Thermostat opens and closes to control the flow of coolant through the radiator.

• Helps maintain the engine at its optimal operating temperature for efficiency and performance.

• Prevents overheating by regulating the coolant flow based on the engine temperature.

• Common issues include thermostat getting stuck close...read more

Pistons seize when lubrication and cooling systems fail, causing friction and heat buildup.

• Pistons rely on lubrication to reduce friction between moving parts

• Cooling system prevents overheating by circulating coolant around the engine

• Without proper lubrication, friction increases and can cause the piston to seize

• If the cooling system fails, heat buildup can also lead to piston seizure

The radiator cap helps regulate the pressure in the cooling system of a vehicle.

• Prevents coolant from boiling over by raising the boiling point

• Maintains the proper pressure in the cooling system

• Allows excess coolant to flow into the overflow tank and back into the radiator when needed

Clamp load is the force applied to hold the clutch plates together, while release load is the force needed to disengage the clutch plates.

• Clamp load is the force that presses the clutch plates together to transmit power from the engine to the transmission.

• Release load is the force required to disengage the clutch plates, allowing for gear changes or stopping the vehicle.

• The clamp load must be greater than the release l...read more

The gear box in a vehicle is responsible for transmitting power from the engine to the wheels at different speeds.

• The gear box allows the driver to change gears to match the speed and power requirements of the vehicle.

• Different gears provide different torque and speed ratios, allowing the vehicle to accelerate, climb hills, or maintain speed efficiently.

• Manual gear boxes require the driver to manually shift gears, whil...read more

Main steering geometry parameters include caster, camber, toe, and steering axis inclination.

• Caster: The angle of the steering axis when viewed from the side of the vehicle.

• Camber: The angle of the wheels when viewed from the front of the vehicle.

• Toe: The angle of the wheels when viewed from above the vehicle.

• Steering Axis Inclination: The angle between the steering axis and vertical axis of the vehicle.

Preload in bearings is the internal load applied to a bearing before it is put into service to reduce play and increase rigidity.

• Preload is required to eliminate internal clearance and increase rigidity in bearings.

• It is commonly used in high precision applications where minimal play is essential.

• Types of bearings that may require preload adjustment include angular contact ball bearings and tapered roller bearings.
