What Are The Characteristics Of Gasoline Engines?

Since gasoline has low viscosity and evaporates quickly, it can form a uniform mixture with air outside the cylinder, and then suck the mixture into the cylinder, or use a gasoline injection system to inject gasoline into the cylinder to expand the gas and do work. The disadvantages of gasoline engines are that their thermal efficiency is lower than that of diesel engines, their fuel consumption is higher, their ignition systems are more complex than diesel engines, and their reliability and ease of maintenance are not as good as diesel engines.
