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

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

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, while automatic gear boxes shift gears automatically based on ...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.

Chamber angle is the area where the cornea and iris meet in the eye, important for proper fluid drainage and intraocular pressure regulation.

• Chamber angle is located where the cornea and iris meet in the eye

• It is important for proper drainage of aqueous humor, which helps regulate intraocular pressure

• A narrow chamber angle can lead to increased risk of angle-closure glaucoma

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

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.

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

ATS system is a type of transmission system in vehicles, while gear and engine type refer to specific components of a vehicle.
