Problems of operating internal combustion engines in dusty conditions
Year: 2025
Type: article
Abstract: The operating conditions of motor vehicle engines in dusty environments resulting from sandy terrain, as well as helicopters using adventurous airstrips, leading to the 'brownout' phenomenon, are discussed. The parameters of mineral dust are examined, including particle shape, hardness, size, and air concentration, along with their impact on the accelerated wear of piston and turbine engine components. It is demonstrated that the primary effect of dust particles entering internal combustion engines through the intake air stream is the accelerated abrasive and erosive wear of individual components and entire structural assemblies of both reciprocating and turbine engines. Additionally, dust accumulation on turbine engine components is highlighted. Both factors contribute to the parallel deterioration of power characteristics, fuel consumption, and oil consumption. Cases of tragic helicopter engine failures caused by the absorption of excessive dust mass are also presented.
