Result: Reaches 37kW (≈50HP) at rated speed; 41-52HP at some points (within allowable error).

4.1.2 Torque

Method: Synchronous dynamometer measurement with power test.

Result: Max torque 74N·m (69N·m in individual tests), within normal fluctuation range.

4.1.3 Fuel Efficiency

Method: Bench tests under idle/low/medium/high speeds to calculate consumption.

Result: Meets average level for same-type engines; no obvious fuel waste.

4.2 Reliability Test

4.2.1 Durability

Method: 20,000km-equivalent bench simulation with component wear checks.

Result: Slight normal wear on key parts; maintains power and stability without faults.

4.2.2 Thermal Shock

Method: 50 cycles of 85°C operation/-10°C cold starts.

Result: Normal low-temperature starts; no component cracking/deformation/failure.

4.3 Adaptability Test

4.3.1 Installation Compatibility

Method: Installation on 2004-2008 Chevrolet Spark 0.8L manual models.

Result: Smooth installation with good component matching; no extra modifications needed.
