The cars need to have a clutch. The reason is that the #engine stays rotating while the wheels are stop at the same time ,
Thus there is no need to turn off the engine when you need to stop the wheels from moving. In addition, the
The electric arc is the discharge of electrical charges through a gap between the conductors and the temperature of the electric arc up to 5000 degrees Celsius is enough to melt #iron and its alloys.
A filter that converts these gases to less toxic gases it called catalytic converter
In the ideal case, the #combustion inside vehicles #engine results a group of gases consisting of #carbon dioxide and #water vapor, but in the normal case, other gases such as carbon monoxide resulting from incomplete combustion (hydrocarbons) also result from incomplete combustion and Nitrogen oxides (NOx) resulting from high temperature inside the combustion chamber are produced.
These gases are highly toxic to the environment in general,
