Auto Engine parts

Your engine needs energy to move, just like humans do. Even while most of us think of the engine as one main component, it actually consists of multiple smaller parts that all operate together.

  • The engine block provides air and oil flow paths to keep the engine cool and lubricated. 
  • A piston converts the pressure energy from fuel combustion into mechanical power. This energy gets transferred into the crankshaft helping it to rotate and spin the wheels.
  • The cylinder head is essential for managing fuel deployment and airflow in and out of the cylinders.
  • The crankshaft is connected to the pistons and converts the linear motion of the pistons into a rotational motion.
  • The crankcase is the largest part of the engine used to store and circulate the oil.
  • A camshaft regulates the closing and opening of the valves and is responsible to start the engine.

Engine and fuel control Unit

Engine control units (ECUs) are electronic control devices that make sure internal combustion engines operate as efficiently as possible. It regulates ignition, fuel-to-air ratio, fuel supply and injection, idle speed, and the timing of valve opening and shutting. 

All of this is crucial to ensure that the engine operates effectively and that emissions are kept to a minimum. The ECU collects information from a number of sensors such as brake system module and temperature and pressure sensors and others to decide the best course of action. 

Without an ECU, a modern automobile won’t run. Thus, it’s critical to look out for issues related to the ECU. The Check Engine Light is the first indication.

How does an engine work?

Modern engines use controlled explosions or internal combustion to produce power. The air-fuel combination inside the engine’s cylinders is ignited to accomplish this. 

Modern engines are also known as four-stroke engines: 

Intake: The piston descends and the intake valve opens during the intake cycle. It introduces air and gas into the engine thereby starting the cycle.

Compression: The piston raises when the compression cycle starts, forcing the air and gas into a smaller volume. 

Combustion: Next, a spark from the spark plug ignites the gas, causing it to erupt. The piston is forced back down by the explosion’s force.

Exhaust: The exhaust valve opens up to let the waste gas from the explosion escape through the catalytic converter before leaving the car through the tailpipe, where it is cleaned.
