Engines types

Please be more specific in what you want to know. Automotive Engines is an endless topic and nobody knows everything about it.

engines are a class of prime movers, which convert thermal energy into mechanical energy.

engines are not only used for automobiles, but they have a wide range of applications, and based on each application , there is a different type of engine.

as rightly said by zaveri be very specific regarding your question

this is a 4 cylinder and 2 stroke

This looks serious ;-)
I want to share with you a recent project I was involved in. I recently worked on The REX which is is a multi-logistic robot, and basically a field porter for military use of small units. The power unit was designed by our engine shop, including 13hp@8000rpm engine, equipped with Motec EFI system. The engine designed to work in harsh conditions.
Here you can find more information about the company <a href="https://www.its-eng.com" target="_blank" rel="nofollow noopener noreferrer">Motion control Systems | ITS - provider of technological solutions</a> and of course this #-Link-Snipped-# project.
I really proud of the result after all the hard work and on its mechanical abilities and would really love to hear what you think.

well engines are designed to convert energy into useful mechanical motion.
generaly they burn fuel to produce energy.
