To improve the deterioration of combustion in the cylinder of diesel engines due to insufficient supercharging pressure under low operating conditions, two-stage turbocharging is combined with sequential turbocharging technology. First, the matching calculation of two-stage sequential turbocharging and diesel engine is carried out through propulsion characteristic tests, and the turbocharger model is determined. Secondly, the combined operation curve of the supercharger and diesel engine is obtained by using GT-power software to verify the feasibility of the scheme. Finally, the bench test is carried out to analyze the influence of two-stage sequential turbocharging on diesel engine performance under propulsion and load characteristics. The test results show that with propulsion characteristics, single turbocharging (1TC mode) can effectively improve the combustion deterioration under the engine load of 0–50%. Under the engine load of 50%–100%, the twin turbocharging (2TC mode) can further increase the air-fuel ratio and improve the in-cylinder combustion; especially at 60% engine load, the fuel consumption rate is 8.08% lower than that of the original engine. The two-stage sequential turbocharging mode can achieve good matching of turbochargers at low speed and full torque as well as medium-high speed and high torque.
