The production of this engine is the largest investment in the country's car manufacturing industry in the last decade, Sattari highlighted.

Low-consumption and high-powered car engines will be mass-produced in the Caspian industrial estate in Qazvin city by the end of this year, he stated.

A straight-three engine, also known as an inline-triple, is a reciprocating piston internal combustion engine with three cylinders arranged in a straight line or plane, side by side.

In these engines, cylinder number one fires, then 180° later cylinder number two fires, and then 180° later cylinder number three fires. There is no power stroke on the final 180° of rotation.

Inline three-cylinder engines are not limited to propelling motor vehicles. They may also be used in general industrial applications.
