An engine is an automobile’s most vital component, serving as its soul and heart. It serves as the principal power source and transforms energy into mechanical motion.
Undoubtedly, car models and designs have changed significantly during the past few years, and strangely, car engines have done the same. And for most individuals who do not enjoy tinkering with their cars, the engine appears to be a massive jumble of tubes, wires, and metal. All automobile owners know that this mechanical component makes their vehicles run. Instead, it is in charge of converting all energy into mechanical form, which enables your car to move and operate as intended.
Car engines come in a variety of designs and with a range of functions. However, they all have the same function. So, it would be advantageous to familiarise yourself with the engine before purchasing one, new or used. This blog will go through the many car engine types you could run into when looking for used cars online.
In autos, a variety of engines are used. The main characteristics of the various automotive engine types are the fuel type and engine layout/number of cylinders (cylinder configuration). Petrol and diesel car engines are among the most frequent in the context of engines. However, that’s only a general description of an automobile engine.
1. Natural-aspiration motor
• An internal combustion engine powers it; a normally aspirated engine, or NA, is another name.
• The air intake in this kind of engine is influenced by atmospheric pressure.
• The intake manifold is not compelled to induct air into it.
• It has less power than forced air induction engines (turbocharged/supercharged).
• Compared to forced air induction engines, it is more dependable and has a simpler structure.
2. A turbocharged motor
• It has forced air induction and an internal combustion engine.
• For forced air induction, a turbocharger is a separate component used.
• A turbocharger consists of a shaft with an air compressor at one end and a turbine at the other—an inlet port and a snail-shaped covering house the parts.
• The input port is where the waste exhaust gases enter under high pressure.
• The compressor is spun due to the exhaust gases passing through the turbine.
• The air compressor draws more compressed air and exits through the air outlet port.
• An intercooler that cools the air before it enters the cylinders is used to feed air into them.
• The engine produces more power because the air pressure is higher than the atmospheric pressure.
3. CRDi motor
• It is a Common Rail Direct Injection (CRDi) engine, a subtype of a diesel engine.
• Modern diesel engines use a fuel injection system called CRDi.
• For fueling all of the fuel injectors, it consists of a single common rail (line).
• Because they use a common rail, CRDi engines can maintain a constant fuel injection pressure.
• The gasoline spray is incredibly fine and is dispersed uniformly because of the steady pressure. It contributes to increased power and efficiency.
4. MPFI motor
• It is a particular gasoline engine called a multi-point fuel injection engine.
• A fuel injection technology used in gasoline engines is called MPFI, comparable to CRDi, a diesel engine technology.
• The MPFI system uses gasoline injectors to precisely supply the right amount of fuel to each cylinder.
• MPFI improves fuel efficiency because of the precise fuel distribution mechanism.
• The output of the engine is additionally increased via MPFI.
• The MPFI engines are sophisticated and even start up easily in cold weather.
• MPFI engines emit fewer carbon emissions since the fuel is delivered precisely.
Cylinder layouts are another factor used to categorise auto engines. Many automakers employ various layouts to fit the engine under the hood or generate greater power. Here are a few of the typical engine designs that automakers utilise.
• The cylinders are positioned linearly in a line parallel to the vehicle (front to back).
• More cylinders can be added because of the linear engine design. For example, the displacement of an engine increases with the number of cylinders. Consequently, there will be an increase in power output.
• Most powerful sedans from the stables of BMW, Mercedes-Benz, etc., use the straight engine arrangement.
• In the engine compartment, the cylinders are positioned side by side (perpendicular to the car).
• Engine parts can be arranged more neatly using the inline configuration. Inline engines are therefore small in size.
• Generally speaking, hatchbacks and compact automobiles have inline engines.
• When viewed from the front, the arrangement of cylinders takes on the shape denoted by the word “V.”
• The cylinders in this arrangement are positioned on either side at a 60-degree angle. As a result, the rows of cylinders are oriented outward in a V shape.
• A single crankshaft at the base connects the pistons of all the cylinders.
• Several cylinders can fit in the V configuration. As a result, it is mostly found on expensive supercars.
• The cylinders are positioned horizontally in this engine arrangement. Both of the cylinder rows are oriented outward.
• Flat engines are not typical, but due to the configuration of the cylinders, they are renowned for providing a low centre of gravity.
• Flat engines hence contribute to driving dynamics and superb handling.
• One of the biggest producers of flat cylinder engines is Porsche, a flat-six (6 cylinder) engine that powers the legendary Porsche 911 sports vehicle.
The number of cylinders in an engine makes up the car’s cylinder arrangement.
• Engine with two cylinders:
These days, cars do not have this kind of cylinder design. Instead, two-wheelers with dual cylinder engines are available. Unfortunately, the lack of use in automobiles results from their weak power output.
• Three-cylinder motor:
It’s a setup that’s typically found in compact autos. However, three-cylinder engines are now also utilised in large hatchbacks thanks to the development of turbochargers. Unfortunately, this engine’s lack of refinement due to its odd number of cylinders is one of its flaws.
• Four-cylinder motor:
It is among the most prevalent arrangements found in contemporary automobiles. Almost all small and big cars have four-cylinder engines typically laid out in an inline configuration. These engines are more sophisticated than three-cylinder engines and can provide more power because of the addition of turbochargers.
• Five-cylinder motor:
It is a highly uncommon setup that is all but obsolete. A five-cylinder has vibrations as well because of the odd number of cylinders. Manufacturers like Volvo, Audi, and others started using five-cylinder engines.
• Six-cylinder motor:
This arrangement can be found in luxury or sporty cars. These engines typically have a straight or V engine configuration. The development of turbochargers has increased the power of six-cylinder engines.
• Engine with eight, ten, twelve, or more cylinders:
The only automobiles with eight or more cylinders are supercars, known as V8, V10, or V12 engines and typically have a V configuration. These engines have enormous capacity, which results in enormous power.
