Inside and Outside: Evolution of the Car Engine Design

Francie Grubba

Introduction

The history of the car engine is a fascinating story that goes back over 100 years. The first cars were powered by steam engines, and even though they were unreliable at times, they paved the way for modern internal combustion engines. Today’s vehicles are much more powerful than ever before, but there are still improvements being made in this area of vehicle design all the time!

Before the automobile era, most cars were powered by steam engines.

Prior to the automobile era, most cars were powered by steam engines. Steam engines were the first type of engine used for cars and remained popular until the late 1920s, when they were replaced by internal combustion models.

The first internal combustion engine was invented by Nicolaus Otto in 1876.

The first internal combustion engine was invented by Nicolaus Otto in 1876. It was a stationary engine, not a car engine. The four-stroke engine is still used today, but it’s been modified over time to be more efficient and powerful than its original design. The four strokes are:

  • Intake: air is sucked into the cylinder through an open valve and compressed by a piston moving down into the cylinder against atmospheric pressure
  • Compression: The piston moves up again compressing air and fuel together until they ignite at the end of this stroke (combustion)
  • Expansion/Power: The hot gases produced during combustion travel out through an exhaust valve while power from expanding gases pushes down on another piston that drives other components such as wheels or pumps

The first electric starter was introduced in 1912 by Charles Kettering and Thomas Midgley.

In 1912, Charles Kettering and Thomas Midgley invented the first electric starter. This device was used in cars starting with the 1912 Cadillac and it’s still used today. The electric starter replaced hand-cranking as a method of starting cars, which had been around since 1872 when Gottlieb Daimler invented it for his invention called “Daimler’s Horseless Carriage.”

The first water-cooled engine was created in 1925 by Piero Taruffi, who is considered as one of the fathers of Italian motor racing.

In 1925, Piero Taruffi was the first to use a water-cooled engine in a racing car. He designed the engine for his own car, the Tipo 6C 1500. This innovation would later become standard practice in all modern day cars.

The first turbocharged production car with a twin-rotor Wankel engine was launched in 1978 in Japan.

The first turbocharged production car with a twin-rotor Wankel engine was launched in 1978 in Japan. The Wankel engine was invented in the 1950s and has been used by Mazda since then.

The twin-rotor Wankel engine is used in the Mazda RX-8, which was produced from 2002 until 2012.

In 1993, Ford Motor Company released its Duratec 25 V6 engine that has a forged steel crankshaft, capable of handling high levels of power and torque without any fracturing or bending.

In 1993, Ford Motor Company released its Duratec 25 V6 engine that has a forged steel crankshaft, capable of handling high levels of power and torque without any fracturing or bending. This was the first car engine to use forged steel crankshaft.

After this breakthrough, other automobile manufacturers were quick to follow suit and started using forged steel crankshafts in their vehicles as well.

There have been many advancements over time for automotive engines but there are still more improvements to come!

New engine designs are being tested and developed. New technologies are being developed and implemented into current production vehicles as well as future models. This constant evolution has led us to an era of high efficiency engines, which have helped reduce emissions significantly compared to older models.

Conclusion

As we have seen, the evolution of car engines has been a long and complicated process. There are many different types of engines with different features that could be beneficial or harmful depending on what kind of car you own. However, one thing is certain: there will always be new ways to improve these machines so we can continue driving them for years to come!
