How Your Car’s Engine Works

How Your Car’s Engine Works

 This is how the combination of an engine, fuel, and air makes your car move, explained in plain English, in case you’re not an engineer.

Most people think cars are a vehicle filled with gas that takes them from one point towards point B. But have you considered, how do they actually accomplish this? What causes it to move? If you’re not already using an electric vehicle for your everyday driver the mystery of what it does can be explained down to the internal combustion engine-that device that is making noises under the under the hood. But how exactly does an engine function?

Particularly, an internal combustion engine is a type of heat engine, in which it converts energy generated by the heat from burning gasoline into mechanical work, also known as torque. This torque is transferred to the wheels in order to make the vehicle move. In other words, unless you’re driving a rusty two-stroke Saab (which is as if it’s a chain saw, and releases oily smoke from the exhaust) Your engine functions using the same basic principles regardless of whether you’re driving in a Ford as well as a Ferrari.

The pistons in engines are able to move up and down within the tubes made of steel known as Cylinders. Think of riding on a bike. Your legs move upwards and downwards to move the pedals. Pistons are linked through rods (they’re similar to the shins of your feet) into a crankshaft and then they move between up and down to spin the crankshaft in the engine in the same way that your legs spin your bike’s. This is then a source of power for the drive wheel on the bike or the car’s drive wheels. Based on the car the engine is usually comprised of between two and twelve pistons inside the engine which has a piston that is moving upwards and downwards within each.

Where Engine Power Comes From

Combustion engine for power generation: Introduction

Combustion engines are well-known technologies employed in trucks, automobiles boats, and construction machinery as well as backup power systems. Combustion engines make use of an expansion process of heated gases in order to push the piston inside the cylinder, and convert the linear motion that the piston is into rotary movement of the crankshaft to produce energy. Although the steam engines that drove during the Industrial Revolution were powered by steam produced externally but modern combustion engines utilized to generate electric power use internal combustion that use an air-fuel is used. mixture is compressed using the piston, and then ignited inside the piston and a cylinder. Internal combustion engines that are reciprocating (ICE) are identified in terms of the kind of fuel used used: spark-ignited (SG) or compression-ignited sometimes referred to as diesel.


Combustion, also referred to in the same way as combustion, represents the fundamental chemical process that releases energy from a gas and fuel mixture. When an engine is internal combustion (ICE) the ignition and combustion of fuel happens within the engine. The engine converts the energy produced by the combustion into work. The engine is comprised comprising a fixed, cylinder as well as moving piston. The combustion gases expand and move the piston which in turn turns the crankshaft. In the end, thanks to a set of gears within the motortrain system, the movement is able to drive the wheels of the vehicle.

There are two types of internal combustion engines that are currently in production that are the spark ignition gasoline engine as well as the diesel engine with compression ignition. They are mostly four-stroke cycles, which means that the four strokes of a piston are required to complete an entire cycle. The cycle is comprised of four distinct phases that include intake, compression combustion, power stroke and exhaust.

The spark ignition gasoline as well as diesel engines that use compression ignition differ in how they provide as well as ignite the fuel. In an ignition engine that uses sparks, it mixes the gasoline with air, and is then injected into the cylinder through in the process of intake. Once the piston has compressed the mixture of fuel and air and the spark is ignited, it, leading to combustion. The growth of the combustion gases pushes up the piston through an electric power stroke. For a diesel motor air is the only thing that is introduced into the engine, and later compressed. Diesel engines spray gasoline into compressed hot air in a quantity, and at a controlled rate, causing it to burn.


In the past 30 years research and development has allowed manufacturers to reduce ICE emissions of the most polluting criteria like Nitrogen oxides (NOx) and particulate matter (PM) by over 99percent to meet EPA emission standards. Research has also resulted in enhancements of ICE efficiency (horsepower and the acceleration time from 0-60 mph) as well as efficiency assisting manufacturers improve or maintain the efficiency of their engines.

What are Different Types of Engine – Complete Explanation

Within this post, we’ll be able to learn about the different kinds of engines. The classification of engines is determined by the type of fuel, cycles of operation, the number of strokes, the type of ignition, the number of pistons, arrangement of valves, arrangement of cylinders kinds of cooling, etc. They are employed in many different fields, including within the automotive industries, aerospace manufacturing, the marine industry etc. in accordance with their performance, they are utilized in various sectors. Therefore let’s look at the various types of engines one by one.

Types of Engine

Basically, the engines are of two types, and these are external combustion engines and internal combustion engines.

01.  Internal combustion engine:

(i). In an internal combustion engine, burning of the fuel occurs within the engine. Two-stroke and four-stroke diesel engines are the instances of internal combustion engines.

There are various types that are internal combustion (I.C.) engine, and the classification of each depends on various factors.

The I.C. engines are classified according to the basis of:

(ii). External combustion engine: In external combustion engine, the combustion of fuel takes place outside the engine. Example: steam engine.

1. Design Of Type

(i). Reciprocating engines: In a reciprocating engine, there’s two cylinders, a piston, and the piston performs a the reciprocating (to and from) movement within the cylinder. In response to the reciprocating movement from the piston it’s known as a an engine that is reciprocating. Two-stroke and four-stroke engines are common examples of a reciprocating engine.


(ii). The Rotary Engine: a rotary engine, the rotating part makes the rotary motion in order to produce energy. There isn’t any reciprocating motion. A rotor is inside the chamber that performs rotation inside the chamber. The Wankel rotary engine , turbine engines are rotary varieties of engines.

2.  Fuel Used

Based on the type of fuels used, an engine is classified into diesel engine, petrol engine and gas engine.

(i). Petroleum engine: Engine that makes use of petrol to operate is known as a petrol engine.

(ii). Diesel Engine: An engine that utilizes diesel for its work is known as a diesel engine.

(iii). Gas engine: A machine that uses gas fuel to do its functioning is known as a gas engine.
