Types of Car Engine

An engine is the soul and heart of your car simply because it is the most important part of a vehicle. It acts as the main source of energy and converts energy into mechanical movement.

Without a doubt, car designs and models have evolved considerably in recent years and, interestingly, car engines have followed suit.

The engines have an interesting history and if you plan to buy a car soon, understanding the different types of car engines will help you make the best decision. People are different and, while some prefer fuel efficiency engines, others focus on greater power.

With that in mind, car manufacturers are working hard day and night to meet the needs of all customers and, therefore, have devised several types of car engines and these are some of them.

The evolution of car engines parallels the development of car models and designs. Simply put, it also has a lot of history. Modern car engines are complicated and specially designed to meet our diverse needs.

Some people prefer more power, while others focus only on fuel efficiency. To meet the needs of all customers, car manufacturers have devised several different types of car engines in recent decades. Today, we will explain each type of car engine to increase your knowledge about the engines.

Different Types of Car Engines.

Spark-Ignition engine:

All gasoline engines are based on spark ignition, where the combustion process of the air and fuel mixture is ignited by a spark from a spark plug.

Although spark ignition engines are commonly known as gasoline engines, they can also run on autogas (LPG), methanol, bioethanol, compressed natural gas (CNG), hydrogen and nitromethane.

Compression Ignition Engine:

In the compression ignition engine, the combustion of fuel in the chamber is caused by the high temperatures reached by the gas or air due to adiabatic compression. The diesel engine is the perfect example of a compression ignition engine, since it only works by compressing the air.

There are numerous benefit of having a diesel engine over other internal combustion engines. Higher thermodynamic efficiency and lower parasitic load on the engine are some of those advantages.

Wankel Engine:

The Wankel engine is also known as a rotor motor because it uses an eccentric rotating system (instead of a piston) to convert the pressure into a rotating movement. It is simpler, softer and much more compact compared to its piston engine or alternative of the most popular competition.

Although it is mechanically better than pistons, Wankel engines are not typically used in the automotive industry. effectively, they are not at all efficient than piston engines. They are plagued by slow combustion, poor fuel economy and poor emission problems.

Since Wankel engines produce more power pulses per revolution compared to two-stroke and four-stroke engines, they are generally used in race cars. The most popular example is the Mazda RX-8.

Reciprocating Engine:

The main component of an alternative engine is a piston that is used to convert pressure into rotating motion. Each piston is placed inside a cylinder, in which gas under pressure is injected and heated inside the cylinder by igniting a mixture of fuel and air.

Then, the piston begins to move alternately (from side to side). This alternative movement becomes a rotating movement with the help of a crankshaft.

Types of Car Engine

Six-Stroke Engine:

Although the six-stroke internal combustion engine is in its development phase, it is already generating a stir in the engine industry.

The six-stroke engine has several dedicated advantages over traditional engines and can result in greater fuel efficiency, less mechanical complexity and lower emissions.

Four-Stroke Engine:

A four-stroke engine is a variant of the internal combustion engine in which the piston completes four times while rotating a crankshaft. The mechanism here is several from that of two-stroke engines.

Here the piston moves up and down twice inside the cylinder and completes two crankshaft revolutions. This type of engines has a high average compared to two-stroke engines. The four-stroke engine is most commonly used in cars and trucks.

Two-Stroke Engine:

In a two-stroke engine, a piston completes a two-cycle power cycle, one up and down inside the cylinder to complete a crankshaft revolution during a single fuel burn time.

In this type of engine, the end of the combustion stroke and the beginning of the compression stroke occur simultaneously, which means that the intake and exhaust functions occur at the same time. The two-stroke engine has a high torque compared to a four-stroke engine.

Electric Motor:

Unlike traditional ICE-powered cars, electric cars get power from their pre-installed rechargeable car batteries. These batteries not only power the engine, but also other electrical equipment. An electric motor simply converts electrical energy into machinal energy.

Although electric cars became somewhat popular at the end of the 20th century, the first electric car was produced at the end of the 1880s. Since 2008, due to concerns about the increase in greenhouse gas emissions and the increase in fuel prices, the growth of electric vehicles has had a positive trend.

Electric motors are more effective than traditional ICE for converting stored energy. They also have greater efficiency on board than diesel engines. Most current electric cars use lithium-ion or lead-acid batteries. Each has its own (des) advantages.

Single Cylinder Engine:

This type of engine has only one cylinder connected to the crankshaft. Single cylinder engines are compact, lightweight and have a better weight / power ratio. It is usually used on motorcycles, scooters, cross bikes and go-karts. Single cylinder engines are not used in modern cars.

HCCI:

HCCI means homogeneous load compression engine. It is a revolutionary step to minimize emissions and maximize fuel efficiency. HCCI technology combines features of conventional gasoline engines and diesel engines to produce a hybrid solution.

Although its lower core temperature (while burning fuel) causes an insignificant amount of nitrogen oxide emissions, it leads to incomplete combustion of the fuel, resulting in relatively high emissions of carbon monoxide and hydrocarbons.

As of 2017, HCCI engines are not commercially produced. However, we still have several working HCCI prototypes.

In-line engine:

What does it mean when someone says it is an online engine? Well, it’s just an alignment or the shape of the cylinders. In inline engines, the cylinders are arranged in a straight line, one behind the other, along with the length of the crankshaft.

Among its three different variants, the online four is the most popular in the automotive industry, as it is compact, saves fuel and offers a higher power / weight ratio than flat six or eight engines.

OPOC engine:

An OPOC engine consists of a piston with 2 cylinders at both ends. There is no cylinder head, and therefore there are no valves.

Compared to conventional engines, the opposite piston engine of the opposite cylinder has very low rolling loads, which means there will be less friction. And since it is quite small, it has a high power / weight ratio.

Supercharged and Turbocharged Engine:

Supercharged and turbocharged engines have some fundamental differences. A supercharger uses the crankshaft to boost energy and produce energy instead of the exhaust current as in turbochargers.

The superchargers are connected directly to the engine through a belt and, therefore, can reach speeds of up to 50,000 RPM. While the turbochargers are not connected directly to the engine and can reach up to 15,000 RPM.

In addition, turbochargers are equipped with instruments that alter smog that reduce carbon emission, so they are greener than superchargers.

Naturally Aspirated:

The natural aspiration engine is a type of ICE in which the air intake depends solely on atmospheric pressure and does not depend on forced induction through a turbocharger or supercharger.

Many sports cars specifically use naturally aspirated engines to prevent turbo lag. Most gasoline engines for cars, as well as many small engines used for non-automotive purposes, are naturally aspirated.
