“…Basically VE of an engine depend upon the inhaling and exhaling of the engine [2,3] and mostly breathing of the engine depends upon the parameters of the intake system. According to Radivoje B et al [4] dimensions of the intake system will have greater influence on VE, VE will impact on the engine performance and empirical studies has proven that optimization of appropriate dimensions can improve favorable VE to high VE [3,4,5,6].…”

“…Which results in lack of optimality in the result, expensive, consumes much time and simulation cycles. [4,12,13] Disregard to the inefficient optimization technique that has been described above, using the Design of Experiments (DOE) appropriately gives optimal results by determining the combination that gives the best response. It is systematic approach in order to obtain maximum amount of output from various types of experiments while reducing the number of experiments.…”

Improving the Volumetric Efficiency (VE) can boost the engine performance. However, there is no Variable Valve Timing (VVT) and variable intake manifold systems especially for most of the conventional scooter engines. Computer aided simulation has significantly reduced the product development time. Users can analyze more design options across multiple design parameters combination. In this study, 150c.c. single cylinder engine parameters were optimized for maximum VE by using design of experiments. The airbox geometry and valve timing and profile are defined as input variables, which are also controllable factors in the co-simulation work of one-dimensional engine simulation software and DOE analysis software. The advantage of this optimization method is that it allows the flexibility to increase the maximum VE for a specific operating condition or to increase the VE for all operating conditions. The results showed that the VE of the conventional engine increased by 9-17% in the speed range of 3200-5600rpm, and by 4% in the remaining speed range of 6400-8000rpm, showing an overall improvement. This method can effectively reduce product development time, budget and simulation cycle.

Continuous compressor improvements demand the measurement of compressor characteristics at corresponding, specific test benches, where standard and non-standard compressor parameters may be measured. Application of inadequate test bench, in addition to measurement errors, may preclude the measurements of parameter's dynamic variations and may even affect the operation of reciprocating compressors as test objects and induce the drawing of the wrong conclusions from the test results. In order to avoid the realization of inadequate test bench, an original mathematical model of the test bench and the reciprocating compressor as a test bench load was formed. By simulations using mathematical models, the test bench behaviour was investigated and, based on the simulation results and previously defined standard and non-standard compressor parameters, the test bench for testing of reciprocating compressors for motor vehicles was designed. The test bench was realized based on the project documentation. The results obtained by measurement on the compressor and on the test bench were compared to the results obtained by simulations using mathematical models. The test bench characteristics were verified separately from the reciprocating compressor characteristics, all by comparison with the simulation results. By comparison between the measurement and the simulation results, a good agreement of the results was established, thus verifying the test bench for non-standard testing of reciprocating compressors for motor vehicles. The realized test bench may be used for measurement of nominal parameters in stationary conditions, dynamic testing of compressor's working processes, tribological testing of the compressors, determination of the compressor's mechanical losses structure, comparative testing of lubricants for compressors, etc.
