What is the difference between diesel and gasoline engines used in walk behind road rollers?

Normally, Walk behind road rollers use diesel and gasoline as power. What is the difference between these two fuels? There must be many people who prefer diesel engines. But there are still people who will choose a small roller with a gasoline engine. Therefore, further in-depth analysis is required.

The molecules of gasoline are smaller, and it is easier to mix with air, and it is not easy to separate from air in the mixed state. Gasoline and air are mixed evenly, and there is basically no situation in which the density of gasoline in the mixture is too low or too rich. Therefore, gasoline engines are highly volatile, while diesel engines are difficult to volatilize. Diesel, when the temperature drops to a certain level, solidified objects will appear in inferior oil, and the oil pipe will often be frozen, making it difficult to start. Need to fill the tank with hot water, or preheat several times to start.

Therefore, gasoline engines and diesel engines have their own advantages and disadvantages. Here, Master recommends that users choose engine rollers with different fuels according to environmental requirements and conditions when purchasing small rollers.

It is recommended to purchase a single-drum vibratory small roller with a gasoline engine. Its fuel consumption is not significantly different from that of a diesel engine, and its rotational speed kinetic energy is not much different from that of a diesel engine. It is easy to start in winter and has less noise.

When purchasing a small double-drum road roller, it is recommended to buy a diesel model. Since the body of a small-sized double-drum road roller is larger than that of a small-sized single-drum road roller, the required power is also greater. At this time, it is better to choose a diesel engine that can provide higher kinetic energy.
