As a tool that travels and lives with us, we should consider RVs usually bear heavy loads. It often needs to be replenished en route, including long journeys, including water, gasoline and fuel. Equipped with some necessary tools, food reserves and various living facilities of the RV itself. A trailer may also need to be hitched. Therefore, the RV spends most of its time in a relatively "heavy" state and may not be suitable for high-speed driving. What is more needed is that the engine can have good torque output at low speeds and obtain sufficient driving force, especially when driving on mountain roads or high altitude areas.
The first advantage of a diesel RV is that energy is relatively cheap. Diesel is cheaper than gasoline, and the fuel consumption of a diesel RV for 100 kilometers is relatively cheap. Think about the RV itself, it's on the road a lot, it's certainly been on more roads than the average family car. Therefore, in the long run, it will save a lot of costs; secondly, the diesel RV has greater torque, because the RV has a heavier weight, greater torque, stronger power, and is easier to climb and climb; the service life of the diesel RV Also relatively long. Because diesel engines are simpler than gasoline engines, they have a lower failure rate and therefore have a longer service life. However, there are also disadvantages: the maintenance cost of diesel engines is higher than that of gasoline vehicles, and diesel engines are relatively noisy.
Gasoline RVs have a longer service life, but their reliability and economy are slightly worse. At present, domestic RVs use gasoline chassis, and most of them are pickup type self-propelled RVs . Although gasoline RVs do not have a scrap life, they are not as good as diesel RVs in terms of power supply reliability and economy. This is because the load capacity of gasoline vehicles is not as good as that of diesel vehicles, and the RV itself is heavier. Therefore, gasoline vehicles are prone to the problem of "small horses and big cars". Condition.
Generally speaking, gasoline engines have weak power and high average fuel saving rate, so the requirements for road conditions are more stringent. Low noise, quick start, high temperature in winter. Diesel engine, no need to adjust for road conditions to run, perfect for touring! RVs have great potential for future development. Major automobile manufacturers should segment the market as soon as possible and seize opportunities and challenges!
Specifically, diesel vehicles have low fuel consumption, high torque and relatively simple post-maintenance. The disadvantages are high noise and vibration, and black smoke in the exhaust gas. Especially in the north, it is difficult to start at low temperatures. Of course, these technologies have improved so much that this isn't a big deal.
If you take into account the economic benefits, especially the salient features of the RV itself, the author still recommends that the diesel engine is the first choice. Generally speaking, for small cars and sleeper cars with low weight, it is relatively cost-effective to choose a gasoline engine from the perspective of comfort.
Diesel engines are of higher quality than gasoline engines, so once they break down, they may cost a lot of money to repair. If compared only with the various maintenance costs of gasoline cars, this kind of maintenance is actually nothing. However, considering that an RV often runs long distances, it may require high power and fatigue resistance, so in this regard, it is better to choose a diesel RV. This is also the main reason why many RVs on the market use diesel.
