What Is Covered Under Heavy Duty Engines Market?

Heavy-duty engines refer to the engines that are used for heavy-duty vehicles. Heavy-duty vehicles usually have a gross vehicle weight of 10,000 pounds or more, which can be worked only with the help of heavy engines. The heavy-duty engine is used in producing power for heavy engines for many sectors, such as marine, locomotive, and mechanical drive applications and electrical power generation. The main types of heavy-duty engines are class 7 and class 8 vehicles. The class 7 heavy-duty engines are defined as vehicles designed to carry heavy loads. The class 7 vehicles usually have three or more axles, with a gross vehicle weight rating of between 26,001 pounds and 33,000 pounds. The most commonly used class 7 vehicles are garbage trucks, city transit buses, and street sweepers. The various horsepower include below 400hp, 400hp-500hp, 500hp-600hp, and above 600hp. It is employed by numerous end-users in such areas as agriculture, mining, construction, transportation and logistics, and others.
