The origin of ATVs is also due to the interaction between people and the environment. Since 1960, snow-capped areas in North America have become popular. This kind of snowmobile that can replace snowmobiles - small engines, off-road three tires, similar to motorcycles, ATV is superior to superior flexibility. Through the characteristics of the terrain, gradually expand the use of ATV, and become a rescue tool for the rescue team to overcome various evil roads. It gradually matures in performance and equipment to be used as a kind of entertainment and interest, such as "Spanish Rally". ATV, the All Terrain Vehicle, refers to a locomotive that can travel on all terrains.
Freely shuttled on the most difficult beaches or muddy grounds, with four large OFF-ROAD off-high-voltage tires, four-wheel independent suspension system and four-wheel drive, manned, loaded, and even rescued in the wild. Non-ATV models are not available. This small, off-road, high-mobility four-engined vehicle is even more maneuverable than the powerful SUV four-wheeled off-road vehicle in some cases!
After the new ATV is filled with gasoline and engine oil (referring to the two-stroke car, separate lubrication type) and the preparation work is ready, the starting method is correct. A good performance ATV should be able to be between -10 °C and +30 °C. Start at ambient temperature and start time is no more than 15 seconds. Otherwise, the starting performance is poor.
After the engine is started, preheat it for 3 to 5 minutes. (The specific preheating time depends on the local ambient temperature: generally a little longer in winter and a little shorter in summer). The engine should be stable at idle speed, its speed should not be high or low, and the sound is soft and there is no obvious noise, which means that the engine idle condition is normal. At this point, the crankcase (ie gearbox) and the transmission parts should be listened to with a slight acoustic response, no noise, and the power transmission is correct and reliable. The operation should be smooth, no abnormal noise, good power performance, acceleration performance, normal fuel combustion, and no overheating of the engine. After parking, touch the right cover of the crankcase with your hand should not be too hot. The thermometer should be used to measure the oil temperature below 85 °C. After restarting, the engine should be idling smoothly, and only the monotonous sound of the mixture combustion explosion is allowed. After the throttle is added, the throttle handle is released and the engine must not be turned off.
