Summary:

To improve the performance and durability of two-stroke engines,temperature of the liner/block is an important parameter, whichneeds to be optimized. In this paper, an attempt is made to measureand investigate the maximum liner temperature of aforced-air-cooled two-stroke engine.The vehicle was tested on both chassis dynamometer and testtrack to identify the maximum liner temperature during operatingconditions. Thermocouple locations were selected at or near the hotspots (TDC and Exhaust port) in the cylinder block. The chassisdynamometer test revealed that the maximum liner temperatures forthe test vehicle were near the exhaust port reference position (34mm from the top face of cylinder block) and TDC reference position(8 mm from the top face of cylinder block near the exhaust port).The Computational Fluid Dynamics (CFD) simulation was used to studythe flow pattern around the block and the results revealed thatdesign modifications can be done on the base cowl to improve andoptimize the cylinder block liner temperature. Hence, the base cowlwas experimentally modified using prototype cowls and was tested onchassis dynamometer to verify the temperature reduction.The target of reducing the maximum liner temperature for thetest engine below the critical value (240°C) was achieved using thefinalized experimental prototype cowl. Confirmation trials on thetest track for the finalized prototype cowl demonstrated that therewas a temperature reduction of 9% at exhaust reference position and5% at TDC reference position
