Flashcards

Air cooling system advantage

Air cooling systems are preferred for engines because they are lighter and have a simpler design compared to water cooling systems.

Tractor application

Tractors are designed for agricultural tasks, with a key function being plowing the land.

Piston ring function

Piston rings act as seals in an engine, preventing combustion gases from escaping into the crankcase.

Octane and Cetane

Octane number measures how resistant gasoline is to knocking or premature detonation, while Cetane number measures the ignition quality of diesel fuel.

Study Notes

Cooling Systems in Engines

Air cooling system has an advantage over water cooling system in that it is simpler and less expensive to install and maintain, with fewer components prone to leakage or corrosion.

Applications of Tractors

Tractors are correctly applied in agricultural purposes, such as plowing, cultivating, and hauling crops.

Engine Components

Piston rings serve the purpose of providing a seal between the piston and cylinder wall, preventing oil from leaking out and ensuring compression is maintained.

Fuel Ratings

Octane number and Cetane number are both fuel ratings, but the key difference lies in their application: Octane number is used for gasoline engines, measuring resistance to engine knocking, while Cetane number is used for diesel engines, measuring fuel ignition quality.

Fuel Injection Systems

The multipoint fuel injection system in an engine functions by spraying fuel into each cylinder individually, optimizing engine performance, reducing emissions, and improving fuel efficiency.
