Engines For  Cars

We will learn about different types of engines for cars in this article. The classification of engines depends on the types of fuel used, the cycle of operation, the number of strokes, the type of ignition, the number of cylinders, the arrangement of the cylinders, the valve arrangement, as well as the types of the cooling According to their suitability, these engines are used in a variety of different areas like the automotive industry, aircraft industry, marine industry, etc. There is a variety of different fields in which these engines are used depending on their suitability.

We will therefore discuss different engine types one by one. Although, there is a wide variety of IC engines to choose from. This article gives a brief overview of the different types of engines used in cars. Turn your ignition on, and keep reading to find out more.

How do car engines work?

The engine begins to run the moment the ignition key is turned on. Do you ever wonder what happens to an engine when it is turned on? Engines today generate power through the combustion of internal fuels or controlled explosions. During the igniting process, the air-fuel mixture inside the cylinders of the engine is ignited. This process is called the combustion cycle, and it is repeated thousands of times per minute by the engine to propel the vehicle. There are four steps involved in the combustion cycle. Hence, the term “four-stroke” refers to the modern-day engine as well. A four-stroke engine includes intake, compression, combustion, as well as exhaust. Each of these steps is explained below.

Types of automobile engines

Basically, the principle behind a reciprocating internal combustion engine is: If you place a tiny amount of energy-dense fuel (such as gasoline) in an enclosed environment, and then ignite that fuel, a huge amount of energy is released in the form of expanding gas. There are a number of interesting things that can be done with that energy. As an example, if you can create a cycle that allows you to set off explosions like this hundred of times a minute, and if you can harness this force in a useful way, you can create what amounts to the core of an automobile engine. Here are the types of auto engines  for cars:

Naturally aspirated engine

Engines with internal combustion are internal combustion engines. Normally aspirated engines are also known as NAS.

  • The air intake depends on atmospheric pressure in this type of engine.
  • The intake manifold does not have forced induction of air.
  • Engines with forced air induction (turbocharged/supercharged) produce less power.
  • Compared with forced air induction engines, it is simpler to construct and more reliable.

Turbocharger

  • Forced air induction is used in the engine.
  • Forced air induction is achieved using an additional component called a turbocharger.
  • The turbine part of a turbocharger is connected to an air compressor part. A snail-shaped cover with an inlet port houses the components.
  • Through the inlet port, waste exhaust gases enter at high pressure.
  • Through the turbine, the exhaust gases spin the compressor.
  • By sucking in more compressed air, the air compressor passes it through the air outlet port.
  • In an intercooler, the air is cooled before entering the cylinders.
  • The engine produces more power when the air pressure is higher than the atmospheric pressure.

CRDi engine

  • CRDi engines are a type of diesel engine.
  • In modern diesel engines, CRDi fuel injection technology is used.
  • Fuel is supplied to all fuel injectors via a common rail (line).
  • The presence of a common rail enables CRDi engines to maintain a constant injection pressure.
  • The fuel spray is very fine and uniform due to the constant pressure. It increases performance and efficiency.
  • Fuel injection pressure is controlled by the engine’s ECU (Electronic Control Unit).

MPFI engine

  • A Multi-Point Fuel Injection engine is a type of petrol engine.
  • Petrol engines use MPFI fuel injection technology. Diesel engines use CRDI technology.
  • MPFI delivers fuel to each cylinder using fuel injectors.
  • MPFI enhances fuel efficiency by delivering fuel precisely.
  • As a result of MPFI, engine power is increased as well.
  • Even in cold weather conditions, MPFI engines start effortlessly.
  • Because MPFI engines deliver fuel precisely, they produce fewer carbon emissions.
