How do cars move? Here we will find out the principles by which cars work. The driving force that moves a car is generated from an engine and
electric motor. Engine technology has a very long history and has used gasoline, diesel and gas. An electric motor uses electricity as new technology
to reduce environmental pollution and resource exhaustion. Let's find out more!
We usually use gasoline, diesel and gas as fuel. These 3 fuels operate in similar ways. Gasoline engines are designed to run on fuel from the fuel
tank, and its spark-plug generates a spark through electrical discharge. When it explodes, the pressure pushes piston downwards and generate energy by
back-and-forth motion. The energy is delivered to the crankshaft, and this causes rotatory power that can move a car. Diesel also has the same process
as gasoline, but there is no spark-ignition device required. A natural explosion by is caused by increasing the heat. Gas engines have the same driving
principles as gasoline.
Cars using gasoline, diesel and gas as fuel contaminate the environment with their emissions. To resolve the problem, Hyundai developed a hybrid
car which uses both an engine and electric motor. The electric motor is operated when the car starts to move, engine and electric motor work in
combination when driving on a flat road, and electric energy from the battery will help the car to drive up a slope. When driving downhill, the engine
is stopped and the battery is recharged by collecting energy. The hybrid car is also called as environmental car as it is able to reduce toxic gas by
over 90% compared to existing cars as their number increases.
It does not use fossil fuel but moves the car by providing electric energy from a high-voltage battery to an electric motor. It applies the
principle of operating the motor by recharging the battery, and this results in a reduction of air pollution due to exhaust gas and helps conserve
scarce oil resources.
Fuel cell generates electricity through direct reaction of hydrogen with oxygen in the air. While still requiring water and consuming energy, a
car using a fuel cell can be an environment-friendly car that may cut down on environment destruction caused by toxic gas or greenhouse gas. Thanks to
the rechargeable fuel cell it is possible to operate the car's motor on electricity only
