This standard specifies the general reliability test methods of motor vehicle engines of complete vehicle on bench, including the load test specifications (such as the alternating load, mixed load and full-speed full-load), thermal shock test specifications and reliability evaluation methods. This standard is applicable to the water-cooling engines of passenger and commercial vehicles, and not applicable to the engines of motorcycle and tractor. The engine is reciprocating type and rotor type one, free piston type engine exclusive. This standard covers the spark ignition and compression ignition engines; two-stroke and four-stroke engines; non-supercharger and supercharger (mechanical supercharging and turbo supercharging, water to air and air to air inter-cooling); and is applicable to the engines fuelled with gasoline, diesel fuel, natural gas, LPG and alcohol fuel. Approval of new designed or important modified motor vehicle engines, approval of engines entrusted to manufacture and quality inspection of currently-produced engines are subject to the reliability test in accordance with the methods provided in this standard.
