Abstract:
      Objective To study the influences of air leakage in cylinder on power output performance diesel engine. Methods A 150mm cylinder single cylinder diesel engine was studied by adding a simulated air leakage device and establishing a single-cylinder engine simulating working process model with air leakage in GT-suit, to study the influences of different opening area on the maximum in-cylinder burst pressure, output power and effective fuel consumption of a single cylinder diesel engine. Results Under the same operating conditions, with the increase of the opening area of the simulated air leakage device, the maximum drop of in-cylinder burst pressure and output power of the single cylinder diesel engine was 7.22% and 7.02%; and the maximum raise of the effective fuel consumption was 5.70%. Conclusion Under the same operating conditions, with the increase of the opening area of the simulated air leakage device, the maximum in-cylinder burst pressure and output power of the single cylinder diesel engine drop significantly, while the effective fuel consumption rises.
