Performance advantages of diesel engines
2025-07-08
Leading thermal efficiency: Diesel engines have a thermal efficiency of 30% -40%, higher than gasoline engines' 20% -30%, mainly due to high compression ratio and compression ignition combustion.
Strong torque output: High torque can be output at low speeds, suitable for heavy-duty scenarios. For example, the Weichai WP17H engine has a torque of 3750 Nm and is widely used in mining excavators.
Excellent fuel economy: Load regulation is achieved by directly changing the fuel supply (quality regulation), resulting in more complete combustion and a 30% lower fuel consumption rate than gasoline engines.
High reliability: no ignition system, low failure rate, and reduced maintenance costs. For example, Weichai engines achieve fault prediction through the vehicle networking platform, with a success rate of 98% in a single repair.
Strong adaptability: It can operate stably in extreme environments ranging from -40 ℃ to 50 ℃, meeting the requirements of harsh working conditions such as mines and plateaus.
